Is there anything remotely comparable to the HP 2570p?

...

Regarding an alternative to the 2570p: I have a 13.3 Thinkpad E330 lying around, that model might be an option for you. It feels quite light for its size and supposedly supports IvyBridge quad-cores and mSATA. Maximum RAM was 16GB if I remember well. Furthermore it seems to run pretty cool and silent.

However I find the touch-pad to be just plain awfully bad... Also be careful if you are replacing the battery, Lenovo has imposed some strict limitations on the model and a battery from an E320 just won't work.

If you really consider buying one, just drop me a line so I can test it with the 3720QM. But anyway I would rather stick with the 2570p if I were you.

Have some newbie questions again, sorry.

 

Just read that the i7-37xxQM CPUs are more power efficient than the i7-36xxQM CPUs. How is that? I have an i7-3612QM with a TDP of 35w. The others have a TDP of 45w, correct? If I can pop in an i7-3740QM with lower power usage (and hopefully lower temps), I'd be tempted to do so.


As I recall from reading this thread, the higher end models that reach higher multipliers, and so frequency, can do it because they are the ones that when made and tested resulted drawing less power and heating up less, and so were labelled as those specific models. On the 2570P, since the power the CPU can draw is limited to around 40W, a CPU that uses more, in this case 45W, but is thus limited to 40W will be, for what matter to us, more efficient that other CPUs at the same multiplier it can reach, but still it will use 40W, unless it is limited to a lower multiplier, so that it can consume less at the same frequency of other worse CPUs. Supposedly efficient CPUs are actually the worse, as the fact that they couldn't reach higher frequencies resulted in them be labelled as efficient models, but to do so they have a limited lower max multiplier, and from tests here 

it seems that at equal frequencies the higher end models are more efficient.

I am planning on picking up a used 2570P as a second portable laptop. The first thing I usually do is a BIOS upgrade and a clean install of the OS. I noticed that HP has periodically released many BIOS updates with the latest being F.65 Rev.A (8 Nov 2016). However this revision comes with the warning "Due to security changes, after this BIOS update is installed, previous versions cannot be reinstalled.". Given this warning I wanted to check if anyone has any comments on going with the latest. Is there any drawbacks like  certain hardware upgrades cannot be done with the latest BIOS. Also any tweaks lost?

 

I searched this topic and couldn't find any information. Any comments would be appreciated!

 

Since there is no comment saying otherwise I take it that updating to the latest BIOS is all good. Thanks.

From my experience with desktops where you can make adjustments to voltage, bus speed, and sometimes multiplier, that's only true if you can undervolt the cpu in question. A lower-binned cpu may or may not be as good as a higher-binned one. Basically, if the production run is of high quality, there's too many "good" processors. They'll test X number at the highest specs, once they get that, the rest are sold as lower end (of course there's more grades than just "high" and "low", but you get the idea).

 

Anyway, to bring it back to the topic at hand, a (maxed out) cpu running at 2.1GHz and a TDP of 35w would draw less power than a cpu running at 2.7GHz and a TDP of 45w. Now, if you restrict the 2.7GHz cpu to 2.1GHz and 35w, they should be neck and neck. The 2.7GHz cpu might, however, be able to run at 2.1GHz at an even lower voltage. If the motherboard supports it, you'd keep lowering the voltage in tiny increments until it becomes unstable, then up it a notch or two. 2.1GHz at 30w would surely use less power. Also, perhaps you got a gem of a cpu and it'll run at 2.7GHz at 35w.

 

As far as I know, there's no way to change the voltage and/or multiplier in the bios. Perhaps it's possible to adjust the voltage after the OS has booted (used to have a Windows program that could do that if the chipset supported it, haven't tried it in a while). It'd be interesting to see if you could indeed lower the voltage.

 

Curious how much hotter the i7-3740QM would run. The i7-3612QM is already running a bit warm. Cores are between 54-61C at low load. Might just need the thermal paste redone, had the motherboard replaced once and it just has whatever the tech put on it.

Well, depends what you're doing. If you're using the laptop in a manner HP supports, all should be good. If you're doing something non-standard, then ?

 

When I get a "new" laptop, I check if a large number of people have problems with the newest bios. If not, I flash it and setup everything the way I want. Then I leave it alone. I'm guessing if someone has a complicated setup, they wouldn't go flashing a new bios willy-nilly unless it was to solve a specific problem they had.

ii. Remove the Setup 1.x bootitem from bootmgr bootmenu with c:eGPUuninstall-disk-image iii. Download BootICE v1.30 or newer iv. Configure the options as shown here

Does anyone still have this picture or instructions on how to configure properly bootloader to automatically load DIY eGPU image, run the script and then chainload bootmgr?

For now I have to manually pick eGPU option from bootmgr and after that pick windows option. I want everything automated.

Tech Inferno Fan July-2015>> Anybody interested in the 12.5" 2570P should also consider a 14" Dell E6430. The E6430 is the superior performance platform due to it's 900P LCD option, NVidia dGPU option, unlockable turbo bins (+400Mhz) on i7-37xxQM/i7-38xxQM CPUs and x2 2.0 eGPU capability. All with a minor size/weight penalty. See http://forum.techinferno.com/dell-la...tml#post118135 for details.

 

Welcome to the 2570P Owner's Lounge! A place to liase with other owners and share useful tips/tricks/mods to get the most satisfying user experience from this exceptional ultraportable notebook.


Release date: 22 June 2012, Model name: Inventec SIMBA, Nick name: EXtremeBook for i7-quad upgraded units

A 2570P can be had for as little as US$250 on ebay-US , still with remaining 3yr global onsite warranty. A bargain when you consider it's upgraded desktop-replacement performance and durable MIL-spec build in a small 12.5" package. A features set unmatched by any other Ivy Bridge or Haswell notebook that remains undisclosed by all online reviews and even by HP. Grab one before word gets out . 2570P highlights being: 

  • socketted CPU allows a easy user upgrade up to a 45W i7-quad, doubling i5/i7 dual-core CPU performance. The result of doing so being the smallest, most powerful systems available that can function as a desktop replacement. Ultraportable competitors like a 12-14" Lenovo X230/X1C/T430s, Dell E6230/E6330, Toshiba R930/R940 or 13" Macbook Pro all have soldered dual-core i5/i7 CPUs making CPU upgrades unfeasible. Need to upsize to a larger 14" Lenovo T430/T440 or (preferrably) a Dell E6440 to get a socketted CPU. 
     
  • rare 5Gbps expresscard slot allows implementing a ~$160 GTX560Ti@x1.2Opt DIY eGPU for gaming graphics, CUDA/OpenCL processing or driving more external LCDs. 
     
  • optical drive can be swapped with a second 2.5" 9.5mm SATA-III 6Gbps SSD or HDD in a caddy & in a JBOD, RAID-0 (performance) or RAID-1 (redundancy) configuration. Can have up to 4TB of internal storage (2x2TB 9.5mm). Or RAID-0 2xSSDs for superfast boot-times and > 1GB/s sequential transfers.
     
  • eSATAp port allows external bootable SSD/HDD to be attached using a single eSATAp cable. Ultra convenient when you consider USB-only systems like Macbooks require complicated software workarounds to get a Win7/8 disk booted off their USB ports.
     
  • upgradeable wifi : can upgrade to recently-released 802.11AC standard with a Broadcom BCM4352 or Intel 7260 HMW card as explained.
     
  • internal WWAN/3G capable : install a whitelisted WWAN/3G card, insert a mobile SIM and surf the internet anywhere
     
  • battery options include a 31Wh 3-cell, 62Wh 6-cell (9hrs) and 100Wh 9-cell battery (15hrs)
     
  • is listed by laptopmag as a top 5 HP laptop of 2013 (Dec-2013) and top 10 business notebook (Apr-2013)


Comparison: http://forum.techinferno.com/what-no...html#post34610 concludes the 2570P is the best one.

Comparison: 12.5" HP 820 G1 (Haswell: 4th-gen i-core) versus 2570P (Ivy Bridge: 3rd gen i-core) in spoiler:


 

  Reveal hidden contents

 

HP's 2013 successor to the 2570P, the "820 G1" is yet another take on an ultrabook thin but with business features and better LCD panels. The thinness and low weight targets have resulted in the 2570P's performance features being sacrificed: upgradeable CPU, ODD for second HDD/SSD, RAID-0/1 support, 5Gbps expresscard slot for eGPU use and probably the upgradeable wifi all gone!! A '820 G1' is a performance downgrade from a 2570P. It is more of a 12.5" successor to the ULV 2170P than the 2570P. What a disappointment from HP. 

Hence why a request for HP to make a Haswell 2570P successor, a "ZBook 12" was emailed. REF: Request for "ZBOOK 12" emailed to HP PSG head executive and reply received. The ZBook 14/15/17 range are HP's chunkier high performance 2013 Haswell notebook range this is missing a 12.5" unit.

Unfortunately the end result of that conversation being that in 12.5" there will only be a ULV "820 G1". The recommendation is to look at a 14" Probook 600 as being the smallest Haswell 2570P replacement. It has a socketted CPU, dual-drives, better HD/FHD panels and even a dGPU option. No expresscard slot though. The 12.5" 2570P small-and-mighty form factor being discontinued. 

I can't help but ask who marketted the 2560P/2570P? They'd win awards for stealth marketting since the 2560P/2570P was severly under-represented against the Lenovo X220/X230.

Comparison: 12.5" HP 2570P (Ivy Bridge: 3rd gen i-core) versus 2560P (Sandy Bridge: 2nd gen i-core)

 

  Reveal hidden contents

Difference between these systems is minor but in nearly all cases favors the 2570P. Hence no surpise the newer 2570P is a costlier unit.

- 2560P is TDP limited to 36W making i7-quad CPUs run at significantly lower-than-specced 4-core turbo frequencies. 2570P is TDP limited to 45W so can run their CPUs near their specced 4-core turbo frequency. REF: http://forum.techinferno.com/hp-busi...html#post79495

- 2560P uses a latch to secure the LCD down resulting in the top cover having latch cutouts as well as latches visible on the LCD bezel. 2570P uses magnets instead. The 2570P's omission of the latches and cutouts giving a cleaner LCD bezel and top cover appearance.

- 2570P nightlight gives a better spread across the keyboard.

- 2570P is RAID storage capable. 2560P is not.

- 2570P can host either a 35W/45W Ivy Bridge CPU or Sandy Bridge CPU. 2560P can only host a Sandy Bridge CPU. Ivy Bridge having the faster HD4000 iGPU and is built using the more power efficient 22nm lithography. There are efficient 35W quad-core Ivy Bridge CPUs. There are no 35W quad-core Sandy Bridge CPUs.

- 2570P has the newer Series-7 chipset which include USB 3.0. 2560P uses a Series-6 chipset with no USB 3.0

- 2560P does however have lower idle power consumption. I could get under 5W with one whereas the best a 2570P can do is 5.4W. This is probably due to USB 3.0 controller on the 2570P.

- 2570P supports DDR3L RAM. 2560P *I believe* does not.

- 2570P has a buggy WLAN bios whitelist allowing any WLAN cards to be used. 2560P only allows whitelisted WLAN cards to be used.

- 2570P has newer WWAN/Bluetooth whitelist cards.

- 2570P has boot Upgrade Bay bios option. 2560P doesn't by default - requires biosconfigutility.exe to set hidden option

Performance upgrade: i7-quad CPU resulting in 'IVB ZBook 12' or 'EXtremeBook'

Can effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Could also be desirable if you wish to lower fan noise and temps. Running a i7-quad with max 99% CPU utilization results in noticably cooler temps than their dual-core counterparts without loss of performance, eg: cool i7-quads by bjorm's i7-3632QM or Aikimox's i7-3840QM. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-3520M 2.9 will not void warranty while a i7-quad will void the warranty if HP know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded 2570P i7-quad system examples are shown in the table above.

NOTE: A 45W CPU can have highest multiplier limited to a 35W CPU level using Throttlestop software. That means a 45W i7-3630QM/i7-3610M (turbo=3.4/3.3Ghz) runs like a 35W i7-3632QM/i7-3612QM (turbo=3.2/3.1Ghz). Best 45W i7-quads being a i7-3630QM (x32) , i7-3720QM (x34) and i7-3740QM/3820QM (x35). There is at max 9% 4-core peformance difference between these with the higher end ones often not being able to maintain their upper multipliers as shown here. Meaning, suggest grab whichever is available and of lowest cost in your area.

The 4-core TDP limit means any faster 45W CPUs do not see any gains. If need more performance and have deeper pockets then consider purchasing a 55W i7-3920XM instead. It has an additional 10W heatroom for turbo. Though it will absolutely need cooling mods to be able to accomodate at that level. <- 55W CPU is being limited to 45W on a 2570P as shown.

It's possible to get and install cheaper PGA-to-BGA converted i7-quad CPUs as demonstrated by pandaleo.

Performance upgrade: external graphics (eGPU)

DIY eGPU to attach a desktop videocard via the 2570P's 5Gbps expresscard slot. Provides accelerated gaming graphics, CUDA/OpenCL processing and additional HDMI/DVI outputs to drive multiple monitors. 

To do this most users only need to set System configuration->Device configuration expresscard slot from Generation 1 to Generation 2 as shown below:

A NVidia GTX460/560/660/670 is a straight plug-n-play implementation on a 2570P when using Windows 7, though Win8.x is problematic (src: here). Win8.x users may consider doing a UEFI installation instead which resolved error12 and gave hotplug capabilities as noted here.

An AMD card, GTX650, GTX750, GTX9xx or older NVidia cards require a DSDT override and (maybe) DIY eGPU Setup 1.x interposer software to eradicate error 12 that prevents their functionality. See the 2570P DSDT override details if using one of these cards.

Implemented on a 2570P at x1.2Opt speed (5Gbps + compression) using a NVidia GTX670 (jacobsson), GTX660Ti (Tech Inferno Fan), GTX560Ti (bjorm), GTX660 (dewos), GTX560Ti (hatoblue), GTX650Ti (phillofoc)

Good Afternoon All,

 

New member here looking for some advice on the wonderful HP 2570p EliteBooks - basically I've recently managed to purchase a couple of them, here in the UK, for myself and a relative (specs are listed below) to replace a handful of older Lenovo ThinkPads.  I'm looking to get some input with regards to recommended BIOS versions that should be installed to improve stability but also does anybody have any information on the exact dimensions of the copper shin that should be used to assist with temperature control.

 

#1 2570p

Model #: A1L17AV

BIOS Version #: F.31 (68ISB)

CPU Model #: i7-3630QM

 

#2 2570p

Model #: C5A40ET#ABU

BIOS Version #: F.33 (68ISB)

CPU Model #: i5-3210M

 

Note that both systems will be getting the RAM maxed out to 16GB, along with getting a 480GB SSD installed as a the primary boot device along with 2TB HDDs via the Optical Drive Bay.

 

Any assistance and input from other members i greatly appreciated.  Thanks

Hello all!

 

Another new member, found this forum purely by chance while I was searching a fault with my 2570p.

 

Machine doesn't turn on whatsoever, AC LED just flashes 9 times when the power button is pressed.  

I've tried the usual disconnect battery and keep power button pressed for 1 min but with no success so I've ordered a used mobo from eBay to try and get the girl going again!

 

Machine is a quad core i5, 10Gb RAM and an SSD.  Looking forward to getting it going again and indulging in some of the mods you guys/girls have found!

 

Thanks for sharing all your hard work!

Hi, Im a new proud owner of a 2570p, I always love the business-class notebooks since my first Thinkpad X60. Now I love my "new" 2570p.  As first upgrade i replace my odd drive for a second hdd caddy, but now sometimes my notebook dont finish to turn off. I read most of this threat and i remember that somewhere is posted the same behavior and some user tap a pin of his caddy or similar. Can someone help me with this issue please?. Thanks!

Hallo and thanks for all the useful information around this notebook and especially the person who collected most of them at the first post. I would like to set some questions for those who can respond, even if this topic seems a bit abandoned:

 

The bios here is F40, cpu i7 3520m.  Cleaned everything, new thermal paste, max temp at full load 90oC with ambient temp 30oC (50-55 idle). A bit high but normal I guess (maybe a better paste would do a bit lower). With linpack (linx) benchmark there might be a critical step further increase at 95oC but this task is a bit heavy (measured 50w consumption with this one). Multipliers stay at x34, small peaks at x36 rarely only at lower temps. No Overclocking.

 

I will save a full BIOS copy as described via the FPT tool, hopefully this will work, so, as I have read here I can restore it if I want.

Then I can apply the OC mod for XTU just to observe the behaviour of the CPU.

 

Q1. is this Overclocking XTU mod a universal add-on to the original bios?

Is this mod, bios version agnostic? Is this a safe bios addon? --- the file (date: 2014) named 2570pOC.bin.

What about if someone wants to use an other bios, will this mod remain or need to be re installed again?

What other bios version do you think I should try after fpt backup? The latest?

 

Q2. Have you ever used a 32GB at 2x16GB DDR3L configuration? The cpu does support 32GB with qm77 chipset, will the BIOS have a chance to recognise those newer modules even if the maximum officially stated value is 16GB(2x8GB) ? example: https://www.amazon.com/Crucial-16GBx2-PC3L-12800-204-Pin-SODIMM/dp/B011ISG132

 

Q3. there are some ram modules that support higher frequencies, 2133,1866 and lower latencies cl9/10 at 1600mhz. Is there any BIOS setting to tune ram parameters at 1600mhz, or it is about the specific module to configure itself upon boot? I have read for fails and successes also. So is it risky so to stay only with 1600mhz specification?

 

Possible CPU Upgrade: As far as I have read here, i7 3720m is a good candidate, even if throttling down a bit. Do you think that considering the current relatively high max temps of the 3520m cpu, will worth the upgrade even without any or with only minimal modifications, with no more than maybe a bit of a thermally glued copper plate above heat-sink or maybe using the heatsink of the 2560p model?

 

thanks!!

Running a 2570p with a i7 3820qm since 2-3 months.

The temperature is NORMAL at 48-55°C on Windows 10 with the core parking feature. Basically the 3820qm  with the core parking, is running as a dual core, until I open a heavy application.

On Windows XP, the temps are INSANE. At least on Windows XP : I am at 60°C with fan at 3200 rpm lowest settings, but the least of application I open like net browsing and it goes up at 75°C.

Previously, with an i7 2620M on XP, I had 74°C with fan off, but above all, 3.5W in idle or internet usage, on the 3820qm I am at 8-9W on idle and internet usage, always on XP. On Windows 10, I run at 3.5W in average.

Now, this is only for simple Internet browsing. When I do slightly more heavy work, for example multitasking, with ALL cores (so same as on Windows 10 or Windows XP), I go up to... 103°C minimum. The CPU throttles. And the fan is on MAX. And it still stays at 103°C.

On the i7 2620m I use to go down to 74°C with max fan and max cores. I estimated the i7 3820qm CPU, without throttling, would reach 130°C with the heatsink.

 

Conclusion : the heat-sink of 2570p is just to small for a 45W CPU. BUT, VERY IMPORTANT, even with the throttling, I get a clear boost (2x more scores in multi-thread benchmark, about 1.15x in mono-thread, even with throttling fully enabled) in computer speed. BUT, second BUT, the CPU is not on is max possibilities. I need a way to extract the 30-40°C additional heat to have the max possibilities of CPU.

Also, it is, at least for the Ivy Bridge, important to use the latest OS for the core parking, but for work purpose I have to use the old Windows XP.

The only way I found to remove the 30-40°C additionnal heat is to plug a flexible heat pipe under the CPU and stick it to a copper plate under the fan. Here is the link for the flexible heat pipe : https://www.ebay.fr/sch/i.html?LH_PrefLoc=2&_sop=15&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xflexible+cpu+heat+pipe.TRS0&_nkw=flexible+cpu+heat+pipe&_sacat=0&_oac=1

I tested also the 2560p heatsink : no real improvements.

 

I had my 3820qm at a very good price (only 110 euros, still expensive for a 4-5 years old CPU and still was the best price), but seriously, 45W is 45W don't need to choose between 3720qm or whatever, just choose the cheapest one available at the time in your country zone.

I would take the 35W quad-core i7, it is very very cheap, and will not heat so much. In reality, the heat is not a problem, cause when I plug the 2570p on a monitor and keyboard the power of this laptop make anyone forget it is a laptup. But the metal case of the 2570p makes the heat diffuse everywhere and is very uncomfortable to use in hands.

Getting 103 degrees sounds way too high even for this kind of processor, and even if you live some place hot...

If we are talking about CPU loads alone: at 100% CPU stressing I hardly get above 90 C with my 3720QM with 8 threads x 3400 MHz, 31 C ambient temerature. It goes to 87 C in about 25 seconds, then starts throttling a bit, maintaining the temperature around those levels. Real internet usage like a 1080@60 YouTube video only reaches about 65 C. Currently using stock 2560p heat sink.

 

So you might want to check how your Ihtel HD graphics is being clocked/utilized under Windows XP, granted there are tools to measure that. I found out only recently that the Intel HD 4000 graphics can produce remarkable amounts of heat, that is, if you stress it right, or maybe if Windows XP keeps it at 100% clock (1350 MHz or so) for no good reason :))

 

After running some modern 3D games (something I do very rarely xD) and comparing with other stress tests, I noticed that serious 3D tasks can push temps well over over 90 C in just seconds. It seems that the GPU can utilize the rest of package (CPU+GPU) power consumption up to 45 watts quite quickly; otherwise consumption only reaches around 40 watts if CPU alone is stressed, as others on the forum have already noticed.

 

BTW I like the idea of a heat pipe leading to an aluminium sheet for cooling. I was considering something like that recently, since I am using a bottom cover made of metal anyway.

I expressively locked GPU at 1247 Mhz because it seems the base frequency of the CPU is related to the base frequency of the GPU. I read this some time ago when the Ivy Brigde has just been released. In the Intel GPU control panel, I set "plugged in" and "on battery" to "maximum performance", and in consequence instead the base frequency of CPU is not anymore 1200 Mhz and 650 Mhz for the GPU, is goes up to 2200 Mhz minimum and 1247. 

 

 

In low performance, I just tested, the idle temp goes from 74 to 62°C but the max temp is still 103°C. Good to know this tip for idle temp. But I wonder how do you manage 87°C on CPU stress test with 8 threads - 4 cores. This seems way to good. I read you use stock 2560p heatsink, is this all ? I repasted my CPU (with clean CPU surface and everything) many many times but this didn't change anything.

 

 

Also I never hit 103°C, it is only in real CPU stress test like Prime95, CPU-Z stress test, or 7z compression, that I reach this temps but it is still very far from the 87°C. Also, I almost never hit my max turbo at 3700 Mhz, my "mean max turbo" is more like 3400 Mhz (measured with HWMonitor) so I lost a lot of performance from the ideal 3820qm (but still 2x more than my previous dual core previous generation 2620m).

 

I just bench marked, I lose like 10% to 15% of performance from 3700 Mhz to 3400 Mhz full 4-cores 8-threads maxed out.  I recognize also that there are a lot of people that have hard times reaching the max turbo on all platforms but this seems very low, I should stabilise the temps from 103 to 60°C (70°C maximum) on load to have average max turbo at 3700 Mhz, which seems impossible with such small heat-sink, heat-pipe, and radiator.

Dunno, I might well be measuring it wrong... Temperature sensors on the CPUs are supposed to have a few degrees of variance, but silicon lottery / binning should be on your side because you got a more expensive model :))

Otherwise I have a custom bottom cover that leaves quite a big clearance under the cooling, but neither this nor the 2560p heat sink should make as much of a difference, too. If you use proper paste and a stock heat sink, you pretty much have the same thing.

 

Apart from that I am running Linux Mint, which in my opinion shouldn't matter much either. 
Anyway if you find it interesting, you might wanna try and see if you get same results under Linux - you only need a spare 2+GB USB memory stick to boot a live Linux Mint. Just download the latest ISO, then install it on the flash drive with something like YUMI, for example: https://www.pendrivelinux.com/yumi-multiboot-usb-creator/
When you boot into the live Linux Mint desktop, open two terminals (one of the icons visible on the lower left). 
In the first terminal enter the following to show live temp stats ("watch -n 1" makes the "sensors" command to refresh every 1 second):

watch -n 1 sensors

And in the second terminal run the following two commands to install and then run "stress" - a small program that stresses your CPU (-c 8 is for 8 threads):

sudo apt install stress
stress -c 8

So you got pretty much the same testing setup that I have :)) I do this live USB routine with most old PCs I refurbish, so I can see if the cooling is working properly.

GPU clock seems to me not to be hardware-locked to the CPU clocks - in Linux I can set max GPU frequency to anything between 350 and 1250 MHz without touching the CPU. If you are lucky, you might find some tool to do that in Windows XP as well (without setting a general power plan).

I just bench marked, I lose like 10% to 15% of performance from 3700 Mhz to 3400 Mhz full 4-cores 8-threads maxed out.  I recognize also that there are a lot of people that have hard times reaching the max turbo on all platforms but this seems very low, I should stabilise the temps from 103 to 60°C (70°C maximum) on load to have average max turbo at 3700 Mhz, which seems impossible with such small heat-sink, heat-pipe, and radiator.

If you are getting simultaneous 4-core clock around 3500MHz, this should already be maximal performance of the 3820QM. The turbo of 3700MHz is only for 1 core at a time, at least according to specification:
http://www.cpu-world.com/CPUs/Core_i7/Intel-Core i7-3820QM (PGA) Mobile processor.html

You might be able to do some overclock if what @istinnstudio mentioned about those BIOS mods is doable, but I guess we got more than enough heat to deal with already xD

 

About the temperatures you want to achieve: I think it is quite unlikely that your CPU will fry any time soon even if it runs around 80-90 C most of the time. More likely would be some damage to other components near the processor, like the motherboard or some plastics, and that only in mid- to long-term future.

For the XTU overclocking: On my tests bios F40 is incompatible with --- the file (date: 2014) named 2570pOC.bin. Intel software does not unlock multipliers. So there must be some kind of bios version per "additional" Intel management. Maybe people that had tried it succesfully can post some version numbers or create one for the latest or the most recommended bios.

 

For the temps: 30oC ambient temp. -> simple cpu 100% less than 90oC. Stress  with Prime95 or Linx about 90-94 max. CPU i7-3520m 2-core / 4-thread. Tested with arctic mx-4 thermal paste.  x34 on 2 cores all the time.

the stock heat-sink and fan is far too small for cooling better than this unfortunately. So even a 35w cpu will heat up much also.

Okay, for a 3520m I find at my turn the temp very high, do you run with 100% fan ? I had a 2620m, which is the older gen, but same laptop, same TDP (35w) and had 74°C average max with 2c/4t full stress test.

Also, before I had something like 85-90°C just after I pasted the CPU. Then with pure randomness I converted a 1080p video that took like 1h to convert, using the 2c/4t, in ~15°C room, then the temps lowered incredibly low to 74°C, then it stayed about at this maximum average for months. So when you repaste you must burn the CPU to make the thermal paste more efficient.

On Windows to run 100% fan you can use Notebook Fan Control, which is working very good (the 2760p fan profile is the same as 2560p and 2570p)

 

But for my new case with the 3820qm, this is not enough. I will change the thermal paste brand to see.

 

batyanko, I will repaste my CPU with a new thermal paste. I will try your tip as I have a multiple partition hard drive with Windows, Linux, and even Android (haha, by the way working great with the 2570p). I will order a new thermal paste brand and try to get the famous CPU copper shim too on Ebay.

Fan turns @ 100% above 80oC (tested with Notebook Fan Control), I have used different methods to put the paste, usually with more or less the same results. And the arctic mx-4 is a good one.

I have a suspicion that a quad cpu can better handle heat with better efficiency considering the more power handled.

Some users report quads as of better heat handling than this i7 2 core cpu.

Performance upgrade: i7-quad CPU resulting in 'IVB ZBook 12' or 'EXtremeBook'

Can effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Could also be desirable if you wish to lower fan noise and temps. Running a i7-quad with max 99% CPU utilization results in noticably cooler temps than their dual-core counterparts without loss of performance, eg: cool i7-quads by bjorm's i7-3632QM or Aikimox's i7-3840QM. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-3520M 2.9 will not void warranty while a i7-quad will void the warranty if HP know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded 2570P i7-quad system examples are shown in the table above.

NOTE: A 45W CPU can have highest multiplier limited to a 35W CPU level using Throttlestop software. That means a 45W i7-3630QM/i7-3610M (turbo=3.4/3.3Ghz) runs like a 35W i7-3632QM/i7-3612QM (turbo=3.2/3.1Ghz). Best 45W i7-quads being a i7-3630QM (x32) , i7-3720QM (x34) and i7-3740QM/3820QM (x35). There is at max 9% 4-core peformance difference between these with the higher end ones often not being able to maintain their upper multipliers as shown here. Meaning, suggest grab whichever is available and of lowest cost in your area.

The 4-core TDP limit means any faster 45W CPUs do not see any gains.

 

 

this does not mean absolute lower temps @ stress but better heat management per cpu power overall performance... i guess

I didn't compare to the quadcore, I compared to the old 2620m witch is a dual core at 35W, basically the previous generation 3520m, where I had 74°C on stress and you more than 90°C on stress.

 

 

Coming back to my quadcore at 103°C, for my part I will try (again) the 2560p heatsink to see if I can lose temps. I strongly doubt this will remove 10 to 20°C just by swaping the heatsinks between 2560p and 2570p, but will try again. If I lose temps, I think you istinnstudio can lose temps also, and go down to about 74°C only by swapping the heatsink.

If not, I suspect either the thermal paste but, I also did repaste a lot, and many times and didn't get no big heat difference. If I don't manage to lower the temps, anyway I will order the famous copper shim on Ebay, it will delay the temperature accumulation.

Does it go really quickly to 103°C, like in a few seconds?

If so, chances are there is a problem with the contact between the CPU and heat sink, that is, the two surfaces not completely stuck to one another. This might be because of them not being parallel, for example. If it fits well, the paste will be nicely squished down to a transparently thin layer.

 

To test for something like that, you might want to turn the laptop upside down, remove the heat sink and put some heat sink from an old broken videocard or a desktop CPU. This way you can put it on the CPU manually and make sure the heatsink sticks flat on it (you will feel it, it sticks with a kind of a vacuum).

This way you can see if the difference between the 2620m and the 3820qm temps are still so drastic (which in my opinion shouldn't be the case). Meanwhile you can detach the 2570p fan and direct it to the new heat sink, even though a large desktop heat sink would cope passively for some time.

 

Or you can try and see what happens if you put a thermal pad instead of paste - pads are made to fill the gaps when the heat sink doesn't fit perfectly. Just make sure not to turn the laptop on without any cooling attached, though that would be a good way to see in practice how it goes from 20 to 100 to full throttle in mere seconds :)) (done that too though...)

 

Otherwise I've played with copper shims too - they are usually handy to replace a crappy thermal pad. Otherwise they make little difference if the heat sink fits well directly on the CPU.

INFO: How to choose the most efficient 45W i7-quad

Summary: recommend a i7-3720QM or i7-3740QM/i7-3820QM as best value CPU upgrades with at most 9% performance variation between the three. The i7-37xxQM or i7-38xxQM being more power efficient, if battery life is important than the i7-36xxQM CPUs.

@bjorm, I recently tested three i7-3740QM CPUs, all SR0UV spec. Notebookcheck says these have up to x35 4-core mode here. Results below for them. I skipped from x13 to x22, starting at x23 to see the ramp up to the the highest non-turbo freq (x27) of the lowest end 45W i7-quad (i7-3610QM).

Comparing the best (#1) and worst (#3) we find there is quite a difference between them. The more efficient one runs x12 at 0.1051V lower, can run x34 even engaging x35 for some time (2mins with bottom cover off) until presumably thermal limits start seeing it pull back the multiplier. It runs x34 at 0.04V and 3.6W TDP lower than the worst one's x33 multiplier. It's x34 mode using the same power as if the the worst was running at x31.5!! The worse one will not run at x35 let alone x34.

Q30PBhx.png

NOTE: Haswell results from a Dell E6440. Ivy Bridge results from a 2570P. Sandy Bridge results from a 2560P.

// = missing data in sample set

XX = specced multiplier unavailable due to TDP throttling or because is an engineering sample (ES)

BOLD = unlocked multiplier

YELLOW = x12 TDP

CYAN = x27 TDP used to gauge comparative efficiency

MAUVE= highest 4-core turbo multiplier used during benchmark

Note: (i) ordered by voltage/TDP at x27 multiplier, lowest to highest

(ii) values reported are the consistent ones observed after initial benchmark start fluctuation

(iii) TDP reported reflective of CPU temperature. Temperature value not being used due to significant individual machine variance, eg: ambient temps, cooling mods and other internal engaged hardware such as HDD, wifi, WWAN, bluetooth.

(iv) Throttlestop can be used to limit the turbo frequency. Eg: Can limit a 45W i7-3630QM to x29 so it runs like a 35W i7-3632QM.

Hello!

 

During the years I used several 3rd gen Elitebooks, 8470p and 8570p models. Currently I'm using a fairly capable 8570p and plan on buying a 2570p for my travel needs.

I'm an audio - video - multimedia - DTP guy, who does lots of audio/video recording and mixing, recently working on live VJ applications.

For my video needs my current 8570p became weak (HD4000), and upon seraching the net for solutions and found this forum, for which I'm very glad.

 

I would like to enhance my setup with a plug-and-play eGPU solution. I don't want to deal with DSDT overrides and custom startups.

 

I read through the whole forum, and for a truly plug-and-play solution noticed the importance of PCI memory space allocation.

So, I would like to stick with the most powerful NVIDIA card, which is perfect for the HP designed PCI allocation method.

 

Currently, based on the forum posts it seems to me, that card would be a GTX 770.

However, I couldn't find info on the GTX 780Ti, which I really aim for.

 

Does GTX 780Ti use the 128MB+16MB PCI allocation method?

Does anybody have such a working setup?

 

My aim is live VJ application both in the studio and on festivals. 8570p + eGPU would be used to design and program the VJ sets in the studio,

while on festivals a fairly powerful 2570p + eGPU would be used to perform.

 

For this I would use an ExpressCard-based solution with a portable case with built-in vents.

I'm not really sure what I have to use as a power adapter, i guess it depends on the TDP of the NVIDIA card.

The Dell might be the perfect solution, because of portability, dustproofing and ruggedness.

However, i would use a desktop computer power adapter, it that's the only way.

 

My questions to fellow forum members:

1. Is there complete list of NVIDIA cards using the 128MB+16MB PCI memory allocation method?

2. Is the GTX 780Ti a plug-and-play eGPU setup?

3. Which are the best power adapters for eGPU setup for traveling and general ruggedness?

 

Thank you in advance for your answers.

Hi, people!

A am a new user of used 2570p. Bougt it like new for outhome use. First of all in my study.

Before buying i read this theme and was quite hesitating what model to buy because of temp and so on but...

 

A have a 3320m cpu and after 40 min in aida stress test it is 100C max on over 3000 mhz. No throttling at all. And this is not my typical workload. So personally for me no need now to mod cooling system.

In general my desktop now is weeker that 2570.  I work with texts and internet.  So the power is syfficient. Now i do not need more.

 

But i need an advise about another thing. 

 

Sometimes i have to work without 220v nearby so i need battery life. As i wrote i do not need power so i minimized everything i could and got an estimated over5 hours on 6 cell bat. It is good for me. Cooling system in this mode switches on evetually.

 

I noticed that by configuring power profiles in win 10 i can see mininum multiplier 12 so the CPU speed is 1170-1200 on 8,5 v.

 

Using throttle stop i can set multiplier on 8 and get 800 mhz cpu on 8,3v. 

 

Is it possible to set mininum multiplier on 8 in win 10 without throttlestop????

 

Thanks.

I can confirm WLAN whitelist is still removed in the newest F.66 BIOS from 2017 (using intel 7260ac card)

Also can somebody explain to me why it is implied in first post that CPU power is somehow limited by BIOS?

Every test I do clearly shows same results of i7-3740qm as reported by other tested machines (W530 and T530 for example). I know programs such as hwmonitor doesn't report "full" 45W of power drain during maximum CPU load, but according to all my tests of pre-haslel CPUs this is normal and expected. This changed in Haslel and newer architectures.

Here's the screenshot: bHG6TCa.png

Keep in mind all cores are clocked at 3.4GHz as this is how Turbo mode works. 3.7GHz turbo clock is only available on one core if it's fully loaded. So nothing is limited, even in case of i7-3940xm CPU as long as 90W PSU is connected and there is a working battery present.

 

After modding cooling system a little bit (enlarged heatpipe with parts of 3mm soldered copper plates, another 3mm copper plate covering entire heatsink from above - mounted with mixed epoxy and mx4 paste - plus additional fan inflow from keyboard + coollaboratory pro paste used on the CPU and notebookfan control used with unlocked highest available fan states). Temperature NEVER goes higher than 93C degrees, no throttling of any kind detected (should occur at ~101C degrees)

Of course temps are even lower when eGPU is used, as iGPU has it's own part in overall TDP.

 

I can also confirm 2133MT/s (1066MHz) RAM works flawlessly in 2570p. After switch from 1600MT/s modules I did note about 35% of FPS increase in source-based games, such as Contagion and L4D2, which is pretty impressive for this old HD4000 iGPU.

 

Geekbench benchmarks:

https://browser.geekbench.com/v4/cpu/3160329 - CPU test alone, no eGPU used - 12597 multicore points, which is almost same as ThinkPad P50 Xeon

https://browser.geekbench.com/v4/compute/844456 - eGPU test (GTX960, 4GB, slight OC) - 80818 points, seems to be about 95% of typical GTX950 4GB results on GeekBench

https://browser.geekbench.com/v4/compute/844263 - iGPU test (HD4000, 1.30GHz, 2133MT/s RAM) - 6953 points

 

If anyone has any questions I'll be happy to answer.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      To anyone wondering about eGPUs on M6700s, its not too complicated, there is just a process that must be done on boot every time:
      You need to have the eGPU connected and powered on before booting the laptop, once you get to the Intel RAID screen disconnect the eGPU and wait for windows to load up, once windows is loaded reconnect the eGPU and you *should* be able to use it and be able to hot-swap it (though you should disable it in windows before unplugging it) installing the normal AMD drivers worked fine for me, though the original release of Adrenaline 19.1 blue screened the first time.
      I usually run with 3 1080p monitors attached to the 480, replaced my old i5 desktop with this laptop due to the convenience of storing everything on one machine, the laptop has a 256gb SSD and 2x 750GB hdds in raid 0, there is a 2TB WD black attached to the eSATA on the dock.
      eGPU and external HDD are powered by a 500W evga desktop ATX psu, the EXP GDC's ATX power adapter was clunky and broke while trying to use it, so I just plugged in a CPU 4 pin cable upside down to power it, not worried about it because the bulk of power is coming from the 8 pin on the GPU anyway.

      The GPU works, The PSU works, The system works. [individually they all do work]
       
      The system works perfectly fine without the WLAN card.
       
      When i put the system to sleep and hotswap the mPCIe riser and WLAN press something on the keyboard.. Restarts.
      Will shutdown in roughly 27 seconds for those 27 seconds it works just fine like how it normally would on external monitor.
       
      When i shut it down and plug the riser and switch it on, same story. 27 seconds.
       
      I don't even see a error. I get to login screen directly. I used DDU already.
       
      I timed it. no matter what i do if i use the eGPU, External monitor it restarts instead of pause-play. I have 27 seconds.
       
      Need help!

      Questions-
      1 is there any way to get this done without the mod?? 
      2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.

      Has any company out there launched a laptop with an external MXM port? 
       
      Just curious since with the boom in the gaming laptop market and some companies launching eGPU thunderbolt enclosures, isnt the MXM faster?
       
      Is it because of licensing issues? or hardware problems?
