[GUIDE] Dell E6530 CPU TDP/multi unlocking


Recommended Posts

I never figured out how to undervolt. The best you can do is use BCLK as high as possible, since BCLK overclocking does not cause an automatic voltage increase, which multiplier increases do.


Thanks!!! That's what I did. x40 would BSOD with an OC over 102 and that's why I finally set @ x39 104,8.

We could overvolt/undervolt our CPU fiddling with the Voltage Regulator but I don't think it would be easy and/or worth the effort

Regarding my non thermal limits I set Long duration power limit 0xB40, Short duration power limit 0xB41 at 100W (0x64) and Long duration maintained Variable 0xB42 to each maximum (0xff) 128 sec.

Is there anything else I need to change?

Awesome! What sort of temps are you seeing running say TS bench at full 4C (unlocked) mode (x38)? Are you being temperature throttled there? Based on temps, is there headroom to consider getting a i7-3740QM (x39 4-core unlocked) or even a i7-3840QM (x40 4-core unlocked).

Oh, and can you link the above post in your E6430 thread? I've headlined a E6430 recommendation over the 2570P as the superior performance platform with not much weight/size penalty at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge.html#post33901 linking your excellent thread in the process.


Thermal limits on my i7-3720QM SR0ML

EDIT : Using cooling mods as described here, there is no temperature throttle now even after 6 minutes 4C@3,98GHz Prime95 full load.
The results here remain for reference of the stock dGPU cooler abilities with the bottom lid closed.


From an average of 55C-60C idle temperature starting a 1024M TS bench (8 threads 100% cpu load) until one core reaches 105C and throttles takes:
 
i7-3720QM _x34_ x35 x36 x37 x38
100 MHz 3' 43" 3' 05" 2' 39"
104,5 MHz 4' 07" 2' 40" 2' 22" 2' 04"


∞ It would complete a 1024M TS bench without throttling.
1 Used Throttlestop to set the turbo multiplier and HWMonitor to monitor temperature and clocks per core.
2 Used freshly applied MX-2 and no other cooling mod. I feel like it would get even better with a small copper shim and/or better Thermal Paste.
3 Test corrected with values from an Air Conditioned Room @ 23°C

E9VCOdxm.png
i7-3740QM @ 3.8GHz 1024M TS Bench screenshot from XTU
(Throttling shown in the end of the full load graph)


My assumption is that a high binned i7-3740QM (like your first sample) would complete an TS Bench 1024M @ x37 or even x38 without cooling mods... 

An 3740QM would add 104MHz resulting 4C @ 4,07GHz (assuming it will clock as good as this chip) and an 3840QM 4C @ 4,16GHz.
With one of these CPUs I don't know why someone would envy a 4C/8T Desktop CPU...

Even my i7-3720QM won't throttle @ benchmarks or games though since 4C @ 3,8GHz would never be @ 100% load. Most times there would be a dGPU or eGPU bottleneck.

@timohour There's a bug in the latitude BIOS that prevents proper TDP management with an xm cpu (both sandy and ivy bridge). TDP settings only function properly when the BIOS does not detect the power brick ID. When it does not detect the power brick ID, it will throttle the CPU immensely, but you can fix this with throttlestop, and both short and long term TDP values will be whatever was set in the NVRAM. When it does detect a valid adapter ID, you are stuck with the CPU's default long term boost power limit no matter what is set in NVRAM, with short term boost disabled. With an invalid adapter ID detected there is no way to prevent dGPU throttling, but this should not be a problem for you since you use an eGPU.

I can verify that your findings on your XM CPU apply on the QMs and possibly every other CPU.

My Latitude also ignores the Long and Short duration power limit that I set in NVRAM... The only setting that it doesn't ignore is the Long duration maintained, and that's why I got tricked that I fixed the issue. I did some primitive cooling jobs on my E6430 (which I will describe on the E6430 thread) and I can now be sure that I am not temperature limited (95°C top after 15 minutes of Prime 95).

The reason that I got tricked is that XTU may report that the Power Time Window is 128 sec but the actual time is the setting in NVRAM. I set the maximum I could (0xff) which is 255 sec, while the Throttlestop TS 1024M 8 Thread Bench took me just 235.524 (90°C maximum) @ 4C 3,97GHz without throttle because it was inside this window.

vvF88G9l.png

I realised that when I tested with Prime95 and after 255 sec of 100% CPU usage I could see that it would instantaneously throttle to x26 for every 5 sec.

Both the power adapters that I have (130W on the docking station and 90W at home) are from Dell (probably valid ID) and I think that I don't have any adapter with invalid ID to check.

Do we have any other options?

You can pull the ID line in one of the power supplies. If you want it to be reversible disassemble the power supply and desolder the line. Alternatively you can just break off the center pin on the power connector.

OK finally Ι used an 90W universal adapter . Also changed settings as follows:

Long duration power limit set to 80W

Short duration power limit set to 100W

1-Core Ratio Limit x40

2-Core Ratio Limit x39

3-Core Ratio Limit x38

4-Core Ratio Limit x38

Result was the CPU to throttle @ x9 BUT using Throttlestop although I could set multiplier manually up to x40 CPU multi won't go higher than x30... Seems like it is throttled @ 3.00GHz.. Any ideas?

Yeah I forgot to say you needed to use TS to get over x9. Have you disabled BDPROCHOT?

Yeah I used ThrottleStop but it would go 10 multipliers lower than I set eg x40, would go up to x30, x39 would go up to x29, x38 to x28 etc...

BDPROCHOT is disabled...

Maybe there is an easy way to mod EC firmware to fool the bios that cpu uses less power?

That is bizarre. It sounds like your BIOS has its own special bugs too.

Ok, found a way to overcome this. I don't know why but once I boot I have to check chipset clock modulation. Then the multiplier would go up to the specified value.

Strange thing is that if I check chipset Clock modulation once it will stop the throttling even if I uncheck it.

:02: I don't get it...

Maybe this is the problem with the original adapter???

Added M4600+M6600 IFR files to opening post, which are nearly identical



Certainly so in the following sections that *might* be useful in enabling the iGPU on AMD dGPU equipped M4600/M6600 systems to extend battery life and make them a better eGPU candidate. TOLUD can be adjusted manually too.

Series-6 chipset support for Ivy Bridge 3rd Gen i-core CPUs

@Khenglish, a while back you suspected Ivy Bridge CPUs could work on Series-6 chipsets. Well, coreboot custom BIOS for a Series-6 Lenovo T420 proves that it is indeed possible.

From Board:lenovo/t420 - coreboot

Tested:

Ivy Bridge processor (see below. you need to modify the config, and it needs more testing)

proprietary components status

CPU Microcode: strongly recommended if you want to use an Ivy Bridge processor

Ivy Bridge processor support

Sandy Bridge and Ivy Bridge processor use the same socket, so an Ivy Bridge processor can be installed. You must modify your .config file and replace all 'SANDYBRIDGE' to 'IVYBRIDGE' to support Ivy Bridge processor, otherwise system will halt when booting. And a patch is going to be submitted so you don't need to manually modify the config file.

Up to now, an i7-3720QM(QS version) is tested. However, the native graphic init cannot work properly until kernel boots up and reinitialize the graphic system. You need the CPU microcode to make the system stable, otherwise VMX will not work and strange kernel panics will occur.

It only took 4 years! Is there proof that it works? There's not much on that page.

Yes, he claims a i7-3720QM QS works in the blurb posted earlier. AFAIK looks like the HD4000 init code and CPU microcode needs updating to support the cpu.

Gerrit Code Review tells us

Quote
northbridge/intel/sandybridge: support both Sandy&Ivy on one board Sandy and Ivy Bridge processors use the same socket, and a mainboard with the socket can support both types of CPUs. However, they use different native graphics init code and cause a crashing if running the wrong code. So it needs a detecting, then selects the right code to run. This patch will add some more code in ramstage (maybe we can add some more flexible Kconfig settings). Tested on a Lenovo T420 with i5-2520m or i7-3720qm Needs testing: desktop/server platforms, 7 series chipset with SNB/IVB Signed-off-by: Iru Cai <[email protected]> Change-Id: I4624759f9c92d56d547db1ab4b9a1d611a182a91

What's interesting is it seems a stock factory BIOS boots but doesn't display anything.

2. I have not tried installing the CPU yet, but the usual symptoms for putting a Ivy Bridge processor is no screen output, but the computer does act like it boots up and halts. Someone did try this with a T520 in early 2013: https://forums.lenovo.com/t5/ThinkPad-W-Series-Laptops/Sandy-Bridge-to-Ivy-Bridge-CPU-upgrade-in-the-W520/td-p/766063/page/2

This begs the question then. Would a SB notebook with MUX switchable iGPU+dGPU configuration switched to dGPU only (such as a Dell E6520) boot with a IVB using the factory BIOS or a slightly modded one with the newer microcode? Or even a Win8.1/Win10 machine with an eGPU attached? In either case the dGPU or eGPU would function in place of the iGPU.

Or even a remote login test?

Yup. Took a while.

Since all H61 desktop boards supported IB cpus with microcode updates it will probably work without issues with a dGPU/eGPU. IMO though, the lack of native USB 3.0 on SB machines is worth the extra $$ for an IB machine.

Q: Do we know if the i5-33x0M series have the extra turbo bins? The desktop i5-33x0 (it is 4C though) have 4 unlocked turbo bins. I am considering a lighter/smaller E6330 but it comes with non-socketed i5/i7 cpus and I was wondering if I can get a bit more out of it or it. I can't find any info online.

Best bet for unlockable turbo bins would be a i7-3520M. I believe Haswell dual-core i7s can have +200Mhz turbo bins unlocked. Not sure if SB ones can too.

For something smaller than a E6430 I'd suggest look at a E6430s over the E6330. It's pretty much the same chassis as a E6330 but sports a thin bezel allowing a 14" LCD to fit. AFAIK it's only single-channel LVDS so can't go beyond 1366x768.

E6430s was noticably smaller and lighter when I compared it against my E6440 though it has a 6-cell that protrudes from the back. The 6-cell wasn't compatible with the E6430/E6440. The 3-cell fits flush, plus there's an option for a modular bay battery.

Review Dell Latitude E6430s Notebook - NotebookCheck.net Reviews

Of course there's also a 12.5" HP 2570P which can take a quad-core socketted CPU. That's if the 12.5" is workable for you. Though no had no UEFI vars or modded bios to unlock turbo bins or TDP there.

You might even want to scout out for a 14" Dell E7440 with i7 CPU. It certainly thinner/lighter than the SB series, has a FHD option but no optical drive or expresscard slot.

http://www.notebookcheck.net/Review-Dell-Latitude-E7440-Notebook.103185.0.html

14" Dell E5440 being a good compromise. FHD LCD option, optical drive, expresscard slot but no socketted CPU. Then there's the E6440 with the socketted CPU.

I'm currently using a E5540 as my main machine. 15.6" FHD, mSATA SSD, 1TB HDD, optical drive, expresscard slot, i5 ULV. Does the job nicely until some 14-15" FHD TB3 machine replaces it.

Thanks for your super fast answer! A colleague envied my E6430 and I was thinking to swap to something smaller/thinner and if possible with backlit keyboard.

12,5" is too small for me at least for my needs right now. I would also like to keep it as low in price as possible.

I would love something thinner ULV based but, from your exprerience, aren't those Haswell ULVs much worse than the i5-33x0M that comes with the E6330/E6430s for as low as 200$?

The only compromise is the standard HD screen vs the FHD options on the 5440. E6440/E7440 is more than I intend to spend for a Haswell. Skylake is on the corner :)

EDIT: AFAIK 6430s doesn't support 3G. The slot is there but there are no antennas due to the bigger screen.

Surprisingly, the 15W Haswell ULVs give CPU benchmark results near the 35W i5-330xMs. Consider a entry level [email protected] performs pretty much onpar to a [email protected]

https://cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-4300U+%40+1.90GHz&id=2054

A [email protected] performs pretty much the same as a [email protected]

if can unlock an extra +200Mhz from say the i7-4600U then you'd be outperforming a i5-3360M/i5-3380M.

Only issue would be if you start putting both the iGPU and CPU under load. Then those 15W Haswell CPUs would start throttling one or the other depending on your iGPU/CPU power balance preference in say Throttlestop. Though I haven't played much with TDP settings on those CPUs as haven't had a need to. Maybe open up their TDP using latitude UEFI vars to eliminate the iGPU/CPU power balance throttling?

EDIT: might be that the i7-4600M has unlockable bins. Not finding if the i7-4600U does too.

If you happen to go down that path then consider 0.0, "Dufus", was able to get fully unlocked multis by removing microcode updates on a i7-4600M and i7-4700MQ: http://hwbot.org/news/12230_interview_with_0_0_overclocking_locked_mobile_cpus/

Got a old-specced (LVDs screen) iGPU E6440 for my brother and an i7-4700MQ off ebay. He wans't interested in crazy performance so I didn't opt for a pricier 4800/4900MQ.

I didn't have much time yesterday to test, but I can confirm that changing the multiplier using NVRAM works for the E6440 too. You can set the i7-4700MQ to run with the extra 2 multipliers turbo (x34 4C - x35 2C - x36 1C) confirmed with Throttlestop too. It will be possibly TDP throttled, but didn't have enough time to test extensively.

 

Saddly enough BIOS version A06 (that came originally with the laptop) seems to have corrected the microcode issue that would allow the 4700MQ to run like an XM chip.

 

When I have time with his laptop (not soon probably since he is hardly here) I am probably going to try to downgrade BIOS to A01 or A02 if possible and check if they have the older microcode which will let me to unlock the multiplier!

Anyone has those tools, I created .py file, and found UEFItool, but can't find others for sites down or not available files... I'd need Universal IFR Extractor and any info on modifiable variables for E6420 (possibly for A23 BIOS if they've changed them). I'd be very glad to get this.

 

Thank you in advance

OK no answer yet, but would like to try something because I've now few other CPUs available in for my 6420 and 6520, second and third gen i7 cpu's. I'd like to test if 29xx XM will work with tdp unlocked (because don't work in stock), also if I can put higher than i7 3615 with unlocked TDP or if there's another mod needed, 3610 works without a problem on QM67, should officially support up to 3615, some even report 3630 out of the box. But I'd like to test as much as possible since I'll be keeping 2 best CPUs in it and others will have to go. 

 

I now have A23 bios already on, can I just simply reflash with A17 IFR file? Because I can't find IFR extractor since donovan's site is "down for maintenance"...

 

BTW.. @timohour I've noticed you've OSX 10.10.1 installed, which way did you prepare your USB and you run/boot from USB in UEFI, legacy with emulated EFI bootloader or straight legacy? I had installed already more than a year ago, but I've changed SSD and now have also second 750GB 7.2k rpm drive in bay unit, but just can't get it install, used like 15 different techniquest, from prepared to combo vanilla with custom bootloader straight to vanilla manually preparation. Just stuck in the middle of loading, no kernel panic, nothing in verbose mode, just freezes.

so first up sorry for the thread necro not sure whats up with the thread most of the links are broken

 

but I managed to piece enough together to make this work I am not  the happy owner of a E6430 with i7-3740QM now running at 4.0Ghz

fresh links to the tools since there appears to been some drama that resulted in breakage (why can't people just get along ffs) 

 

UEFI Tool https://github.com/LongSoft/UEFITool/releases I used NA A56

IFR Extractor https://github.com/LongSoft/Universal-IFR-Extractor/releases

 

and to anybody that needs it here is the pre extracted IRF for a Dell Latitude E6430 BIOS A23 the latest and probly last bios as of this posting

DELL 6430 BIOS REV A23 IRF_.zip

 

as well as a minimal efi shell

 

efi shell a minimal grub based cli with the setupvars tool

efishell.zip

 

dell.zip contains the python script for extracting uefi images from dells updater .exe (YOU MUST USE PYTHON27 To execute this script!

 

dell.zip

 

but in case you didn't want todo what i had to and spend 3 hours trying to navigate flamewars and broken links it boils down to this

get the IRF  table for your laptop 

boot to a efi shell

config your desired vars remember you need to make sure the following are disabled

 

TDP lock disabled

config lock disabled 

TDP config up ENABLED

then you can set your desired TDP and multis 

remember things are in hexadecimal so you need to remember to convert 

 

for example setup_var 0x25 0x28 will set the one core turbo multi to 40x

here is a handy converter to make it easy

https://www.rapidtables.com/convert/number/hex-to-binary.html?x=0x28

Same goes for tdp and other things you need to set

 

be prepared to open your device and disconnect the cmos battery should you mess up and cause a no boot
