HWinfo says it's "SROMJ".

Yes, that's an OEM chip, just an inefficient one. : http://www.aliexpress.com/item/Loptop-CPU-Intel-Core-i7-3820QM-OEM-SR0MJ-2-7G-8M-L3-Turto-3-7G-brand/823303261.html .

I'm of the opinion that you'd be better served by offloading your CPU and getting a i7-3740QM: http://www.aliexpress.com/item/Laptop-CPU-Intel-Core-i7-3740QM-OEM-SR0UV-2-7G-6M-L3-Turto-3-7G-brand/823461881.html . It will better your 4-core performance, getting somewhere between x33 and x35 4-core performance. Or even consider a i7-3630QM. One of those would have a good hitting x32 : Wholesale and retail LAPTOP CPU PROCESSOR INTEL CORE i7 Mobile i7 3630QM SR0UX 2.4GHz 1024MB SOCKET G2 CPU OEM-in Processors from Electronics on Aliexpress.com

So based on the aliexpress prices, a i7-3820QM costs US$149 more than a i7-3630QM yet in your case gives equal or even 100Mhz less 4-core TS-bench performance. This indicates poor grading/binning by Intel. A budget CPU should not be outperforming a premium one.

Would you mind submitting the complete x12, x23-x35 TS-bench TDP versus multiplier data for that i7-3820QM like here? We want to note this poor result so other 2570P owners may choose to avoid acquiring that series of CPU.

Thanks again for all the information. I'm gonna stick with it for now. I will make that report and post it tonight (my timezone :) ). Should I post entire logs? If not, which VID/TDP value should i choose? Highest TDP per multiplier?

Create a tabulated TDP/VID versus multiplier chart. The multipliers required being x12, x23 to x35. Examples and details instructions at the bottom of http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432 .

Hello again. I finally got my BCM4352 WiFi adapter up and running. Just wondering if there are any specific battery tweaks besides the Gen1 port for the WiFi adapter?

And as follow up, is there any way we can spoof our device to run WiDi? Got everything but the driver working for WiDi. lol

Ok, here's the data i gathered from tsBench: After x31 nothing changes so i just skipped it. Seems i've got the worst chip of all. :(

Agreed. It's unfortunate that you have the worst OEM chip we've seen so far. It has 4 strikes (XX) against it's 4-core available multipliers. Before yours the maximum strikes was two against OEM chips with the majority having only one strike. Your results now appearing int he summary table: [url]http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432[/url]

I replaced 3920xm QC22 es to 3740qm SR0UW BGA TO PGA and saved money. BGA TO PGA version cost about half price of original PGA version, just a little worry about the quality. The PGA pin is not so good at install to the socket. And it has two PCB boards, so is thicker than original PGA. I should pay attention to fixing heatsink screws slowly, prevent breaking the core. [ATTACH=CONFIG]12015[/ATTACH] [ATTACH=CONFIG]12016[/ATTACH] CPUZ detects it as PGA, but AIDA64 and hwinfo64 can detect it as BGA version. [ATTACH=CONFIG]12017[/ATTACH] also make a throttlestop test, cannot stand on x34, quickly get down to x33.

There's some options for battery life in the BCM4352 adapter settings->properties->Advanced. wifi driver itself. Eg: power output, minimum power consumption. Can play around with those. There's other important system wide battery life tweaks.

I replaced 3920xm QC22 es to 3740qm SR0UW BGA TO PGA and saved money. BGA TO PGA version cost about half price of original PGA version, just a little worry about the quality.

Thank you for posting this update. You are the first 2570P owner to install one of these BGA to PGA chips. I've added your Throttlestop bench results at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432 . We see you started off with a i7-3610QM (x31), then acquired a i7-3920XM ES (x32) and now settled on a i7-3740QM (x33). From start to finish, you've managed a +200Mhz 4-core improvement. While that may not seem that much, your tinkerings have answered these important questions:

  • will a 55W i7-quad be TDP limited to 55W in a 2570P -> no, the 2570P BIOS will limit those CPUs to 45W TDP.
  • can I install a PGA-to-BGA i7-quad CPU in a 2570P -> yes, as confirmed by user pandaleo here

Thanks Tech Inferno Fan. I did read on the tweaks before posting. What I meant was if there were other tweaks for the WiFi card other than those listed in the first page (like enabling WiDi or something like that). I'm holding off most of the power/battery tweaks until I get my RAM and processor.

@pandaleo, good to know that the BGA to PGAs work quite well. At least the issue regarding poorer performance due to added thickness from the customized pins was resolved. Question now is if the vendors were correct in claiming that the BGA to PGA are more heat efficient. Do the numbers prove that?

I personally still feel that how tight the processor is to the mobo is the determining factor for performance. The coper shim experiment and now the thicker BGA to PGAs try to hint us there.

The magician's trick - NBR's top 50 list sees the 2570P disappear!!

The beloved 2570P has disappeared from NBR's top 50 list: Best Laptops - The Top 50 Most Popular Notebook Computers .

It's been mostly in the high teens and only yesterday was number 25 with 593 views, according to google cache. Yet today, even the "Western Digital Black^2 Dual Drive Review" with 40 views at the last position (50) has outranked the 2570P.

Why disappear? I'd speculate, based on how quickly ebay 2570P units have been disappearing, that the 2570P huge performance potential at relatively low cost is becoming more widely known. Has that knowledge been cannabalizing sales of performance inferior ultrabooks and pricey workstations? Probably .. Is that good for vendor upgrade system revenue? No.

Hi all,

So after the fiasco with my last 2570p I ended up replacing both the notebook and the processor (i7-3720qm). Good news is that I managed to get the eGPU setup working with the notebook using the i7-3320m processor which it came with. Oddly enough GPU-Z showed it only being a x1.1Opt setup, even though I have a PE4L 2.1b which supports x1.2Opt on my X220 thinkpad. Is there some setting I need to change in the BIOS to allow faster link speeds?

Bad news is that the i7-3720qm processor was working for a few days but today it stopped working and now the laptop only boots to a black screen with blinking LEDs, which HP support website says means that the CPU is not functional. Have tried reseating the CPU but no luck yet, may just be another defective processor that I have to replace :\

Change bios->System configuration->Device configuration expresscard slot from Generation 1 to Generation 2 as shown below:

Please post your complete system spec so you can be listed on the opening post of this thread. Better yet, if you get the i7-3720QM working, please post it's TDP/multi data to be included at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-37.html#post77432 . We currently only have one sample of that CPU on that table.

Is the 5GT/s x1.2opt setup in our 2570p really viable for VR gaming? Just read this rant (Timothy Lottes: New Laptop + VR = Fail) of an NVIDIA guy regarding mobile PCIe bandwidth and dGPU drivers increasing latency, rendering his notebook useless for VR.

Will eGPUs suffer the same fate?

Tim is pointing out the issue with Optimus introducing latency due to the dGPU not being wired to the LCD but rather is routed out via the iGPU. This is not a problem with a 2570P + eGPU if you have an external LCD wired up. I wonder too if he's checked if his notebook wires up an external LCD directly to the dGPU too? That would solve his isue.

The problem with expresscard/mPCIe eGPUs is the bandwidth. 5Gbps, 4Gbps after overhead + x1 pci-e compression. The best solution there in terms of keeping a notebook is to either

(1) get a notebook with a dGPU

(2) get a Thunderbolt2 equipped (x4 2.0 - 16Gbps) notebook such as a ZBook15/17 or Macbook Pro 13/15. This is now viable since an affordable eGPU adapter/enclosure has recently been introduced: http://forum.techinferno.com/diy-e-gpu-projects/7205-us%24200-akitio-thunder2-pcie-box.html#post97941

Thanks Tech Inferno Fan. I knew about the bandwidth limits so I didn't mind a watered down, upscaled experience. Was more concerned about latency leaving a blurring, nauseating effect hence the question.

While we do not have 100℅ eGPU performance yet, this notebook remains for me as one of the most powerful, portable devices available for gaming. Great bang for the buck!

To reiterate, Tim's point about latency (dGPU->iGPU->internal LCD) is not relevant so long as you use an external LCD with your eGPU. There it's a direct path (eGPU->external LCD) for the data. If you use the internal LCD mode then you would experience the latency (eGPU->iGPU->internal LCD) but worse is you'd load the already limited x1 bandwidth with the internal LCD display traffic. External LCD is definitely recommended for eGPU use on a 2570P to maximize performance.

Yes, a i7-quad upgraded 12.5" 2570P is the most bang-per-buck and bang-per-cm^3 you can get. FYI: I found that 4th generation Haswell runs hotter than 3rd generation Ivy Bridge at http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 without any notable battery life or performance gains. The spruiked Haswell battery life gains are confined to the ULT platform used in Haswell ultrabooks. Those combines a slower ULV CPU and chipset on the CPU.

Haswell being a hotter CPU explains why Dell elected to not offer a factory i7-quad in their Haswell 14" E6440 as they did in the previous Ivy Bridge 14" E6430. We can see too HP made the correct decision in not updating the 2570P to Haswell internals in say a 2580P refresh. Such an investment of their time and effort could even be considered as taking a step backwards. Intel dropped the ball on this one.

Can you too post your full system spec o including upgrades, so I can include you on the opening post of 2570P systems? Putting it in your signature making it even easier to know where you are coming from when responding to your posts.

@Tech Inferno Fan Thanks, changing it to Gen 2 fixed the problem. My current spec is the following:

i7-3720qm

GeForce GTX 560Ti with x1.2Opt

4 GB RAM

500GB HDD

3dmark06 score was 23875, about 6000 more than my X220 :D

I managed to get the i7-3720qm working by opening up the cover and letting the processor + heatsink cool down for a bit. However it seems that I have to do this every time I restart which is quite annoying, as the system will boot to a black screen with the blinking caps lock error if the processor is too hot on boot up. Also have ordered 4 GB more ram and a 256GB Samsung 840 Pro SSD which should boost performance quite a bit :)

I'll try to post throttlestop data once my SSD gets here and I get my system set up to be more stable.

Thank you for the spec list and congratulations on a fine 3dmark06 score :) I've added you to the opening post with current configuration.

Please consider the cooling details to sort out your heat issue. Easiest thing you can try it to use one of the fan control utilities to run the fan at 100% when loaded and/or remove the bottom cover. I did both when running my eGPU/CPU benchmarks, plus used a 25x25x1mm copper shim. That maximized CPU and corresponding eGPU performance. Never had a 'too hot to boot' situation.

Your Throttlestop TDP vs multi results will indicate if you've got a cooler or hotter CPU.

What thermal paste are you using? If you're using a generic white paste, I would upgrade to at least Arctic Silver 5 and consider running a copper shim like most of the 45W quad core crowd on here. For a point of reference, if i'm transcoding HD movies with Handbrake or playing games with lots of physics computations my CPU will hit temps over 100C. This is with a 35W quad core, so I imagine that the 45W CPUs will hit those temps quicker than my 3632QM.

If you follow the instructions with the AS5, to include the heatsink tinting, you hopefully will have better results.

@phillofoc I use GELID GC-Extreme thermal paste, have simply been applying a small pea-sized dot to the processor before attaching the heatsink. Is that heatsink tinting method specific to AS5 or can it be used with any thermal paste? If so I will give it a try.

I've tried putting a copper shim between the CPU and heatsink and I would still get the same error where the laptop boots to a black screen. Only solution that has completely eliminates the problem is using the factory i7-3320qm processor instead.

You actually might be using way too much thermal paste. You should only need about half to a whole grain of rice sized spread of goop to make it work. The purpose of the paste is to fill in the microscopic voids in heatsink and CPU, so you hardly need any at all for it to work properly. Otherwise you might be retaining heat to the point where you could have issues. The tinting part is optional, but Arctic Silver says that it should reduce the break-in time for the setup.

Next time you open up your laptop, try these instructions: http://www.arcticsilver.com/pdf/appmeth/int/ss/intel_app_method_surface_spread_v1.1.pdf

You also don't need to remove the entire bottom to get to the heatsink. You can get to it if you're careful by just removing the service cover. I don't know if this will work if you have a copper shim, but that's how I did it and it worked great.

Hi, I would like to ask some advices, I do not have a 2570p, but a 8570p, in a former Probook 6560b chassis. As I like to tweak it, too, I did not find any other thread regarding it, so I will post here, as I think they are very similar in some ways. Please excuse me if this is not a good place to post, and do let me know.

Now, about it. First it was a Probook 6560b, with i5 dual core. I upgraded to 2720QM, to find very big temps, over 90 degrees till 100 in prime, at 3,4GHz, no throttling at all. After discussion to HP support ( I believe by now you have an idea of their kind of way regarding these issues) I began to search for better cooling, mainly adding copper plates over heatsink, cutting a hole in the back cover and adding a big aluminum plate at the bottom. I will show the photos from it's original state.

Now, only the chasis remained from original computer, the mainboard is a Elitebook 8570p, ODD, eGPU expresscard, 3632qm with added holes in the case and an extra 6 cm thick cooler powered by 5V from the regular fan, and the processor limited to 2,6GHz with Thottlestop, because of the fan noise. I saw somebody did a tweak on the fan, by adding some diodes; is this for the noise, or did I misunderstood, and if so, could you explain more details to me?

Also, now I have a Elitebook 8570w backlit keyboard, that fits as size, and as the connectors position to the mainboard. For the illumination I saw hot to power it from 3,5V with an on off swich; however, the contact of the keyboard do not match, and therefore, the keys are wrong, only few work when pressed, and are not what they sould be, and shift or control seems to be always pressed; can anyone help me with this, is there a way, if I could change the order of some pins, to make it work? If so, how can it be done, how to know the correct layout?

I am attaching the old cooling mod pictures, and please again excuse me if I posted on a wrong place

Thank you

2720QM = 45W Sandy Bridge 2nd generation

3632qm = 35W Ivy Bridge 3rd generation

Your cooling mods are not necessary to run the 3632QM. You can see the significant TDP difference between the two at http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 . If you decided to run a 45W Ivy Bridge CPU you would probably see TDP throttling before temperature throttling. The 8570P/6560B hybrid you have has a decent heatpipe on it to be able to remove heat.

2570P fan diode mod was to decrease cut-in RPMs and so quieten the fan.

Thank you for reply. It was actually 2760QM, I mistook it. The reason why I bought the new one was just this, the 32W TDP. To be more specific, I added 2 pictures, both taken now. One shows the current state of the cooling system, the other the temps after one hour of prime95. They get as far as 90 degrees, with Package Power Limits set to 26W, and multiplier set to 26T, therefore clocking to maximum 2,4GHz, from it's possible 2,9. I would add I took the temps with an external thermometer directly to the heatpipe and it was showing 55 degrees Celsius, while internal sensor was showing about 80. And one more thing: neither the probook mb, this one, and neither one of the two processors ever throttled, even with stock cooling and prime on. Someone suggested the internal reading could be wrong, but I had 2 different processors and mainboards, and all showed similar results. I would like of course, to use it for prolongued at full 2,9 speed, but these temps at only 2,4 kind of worries me, that is why I ask your opinion about it, why do you think the temps are shown so high.

And the second question would be about the new backlit keyboard, if anyone can help me adapt it.

Hi guys,

first a big thank you for compiling so much information about the 2570p neatly here. However, after browsing all pages, googling and using the forum's search, I still don't get which CPU-Socket type to get if I want to do an upgrade. Most of all quad-core upgrades mentioned are available as BGA1244. If memory serves right, the 2570p has a BGA1023 socket. Can you just drop a BGA1244 CPU in a BGA1023 Socket, or does one have to get a PGA988->BGA1023 modded CPU?

Thanks in advance

BuzzDee
