Unlocked ThrottleStop 4.10 for Alienware M17X R3 Qm proccesors

Im using throttleStop due to XTU 2.1 IOCBIOS buggy behavior and speed drops 3.2 GHz to 3.0 GHz + unnecessary services, so I found that throttleStop 4.10 works with no issues, to unlock TDP TPL values you need an unlocked system Bios currently A12 or A08/A10 : http://forum.techinferno.com/alienware-m17x/2279-[m17x-r3]-bios-a12-unlocked-sata-tweak.html

1) F2 >Bios>Power>Advanced CPU Control>Turbo PWR Limit MSR Lock>Disabled

2) Advanced Options> Turbo set maximum short term turbo power limit 72> Long duration 56>Long term Power Limit 72>F10 save/exit.

3) Open ThrottleStop>click TPL>look for the default maximum short term turbo power limit (W) and set long term turbo power limit (W) with the same value: 72>hit apply>options make sure Do not reset FID / VID on Exit is checked the same with start minimized just leave it on Monitoring only mode and close it.

4) Open Task scheduler -click Task scheduler library >right click create task A) name your task >set Run with the highest privileges >Configure for Windows 7 B) Triggers>New > Begin the task: AT Log on - here is the trick: task scheduler must start ThrottleStop only after Intel(R) Management services does so you must set a delay start*, click the 15 minutes option and set it to 3 C) Actions> New >Start a Program >Browse ThrottleStop.exe D) Conditions >uncheck everything E) Settings ->check allow task to run on demand >unckeck Stop the task if runs longer than 3 days >Check If the running task does not end when requested force it to stop.

ThrottleStop 4.10 : Downloads


I use both ThrottleStop and HWinfo fan control as tasks so my system stays always cool, edited the ThrottleStop .ini with ExitTime=5 parameter (starts and exits 5 sec later), now when requested the CPU will run at full speed forever.

* -Delay start may vary depending on your system Hardware, if throttleStop launches first Intel management services will override it.




Thanks widezu69 and unclewebb for ThrottleStop

Capture2 is with 108 amps

 

this looks promising.

 

Thanks for the write up j95.

Question: What is the point of this? Is it to keep the CPU turbo tdp high so that the turbo does not fall off?

Fortunately, XTU works on my computer

 

A 2nd Generation Quad Core CPU like the Core i7-2670QM has a maximum short term turbo power limit of 60 watts and a long term turbo power limit of 48 watts. These limits are hard coded into the non-Extreme CPUs. Going beyond these limits on a Core i7-2760QM should not make any difference to performance. In theory, setting higher power limits will simply be ignored.

That's according to the Intel datasheet for these CPUs but who knows, maybe it is wrong. Can you try doing some wPrime benchmark testing to see if setting this to 72-72 has any advantage?

Can you set the Turbo Power Limits in the bios to 60 short - 48 long? If you can then there is no need to use XTU or ThrottleStop. You can use ThrottleStop for monitoring purposes or to adjust the multiplier or turbo power limits lower than the preset maximums but you can not go higher.

 

Monitoring only mode the multiplier stays 32 all the time with XTU it drops after 80% to 31 and when it doesn't the clock modulation does PTune service randomly stops working.
Less services running I have 41 processes running.
I need to keep the Cpu between 36 to 41 for Media Encoder Premiere Pro, the 2760 is limited for this Apps.
I have the GTX 580M so i can use MPE, ray-traced 3D rendering engine CS6 is all about GPU but still need those 32 multipliers at full speed!
Blind flash from A04 with Svl7 unlocked A10 bios with Sata fix, works the same for the Gpu power throttle as A08 did and it is more responsive not sure if it is making any difference with ThrottleStop.

The defaults shown in ThrottleStop are 72 Short 48 Long, changed the default 97 amps to 108.
The multiplier stays 32 all the run Setting both to 72W in monitor only mode.
There is no need to turn it on, task scheduler launches ThrottleStop minimized right after intel management services then 5 sec. later exits and settings stick.
Congrats. for the AnandTech article!

 

Thanks for posting that pic and thanks for the Anandtech congrats.

I am glad I didn't cap the Package Power Limits in ThrottleStop based on what the Intel datasheet says. I trust the ThrottleStop multiplier during a wPrime run more than the docs.

Have you tried lowering the TDP limits while wPrime is running? You might be able to go as low as 60 - 60 and still get the full multiplier during wPrime.

The ThrottleStop TDP settings work independently of the Turn ON - Turn OFF button. I wasn't sure how to read the default TDP so I decided to use whatever TDP the user previously selected. If you click on Turn Off or exit ThrottleStop, it just leaves the TDP register as is. There have been more thumbs up than thumbs down so I just left it like that.

Do you need a ThrottleStop delayed start feature? Perhaps a simple INI option. The Task Scheduler is very limited when it comes to choosing how much time you need it to wait.

 

No changes 60 - 60

 

ThrottleStop shows about 57 watts so I thought it would still be using full turbo boost at 60 - 60.

That does prove that the long term 48W number in the Intel Datasheet for your CPU is not accurate.

With the non-Extreme CPUs, is there any need to run XTU at all? If the TDP register is unlocked in the bios, you should be able to run ThrottleStop by itself and bump it up to 72W for the long and short limits.

 

So i can overclock my i7 2670QM 2.2GHz to the Turbo that is 3.1GHz? with your trubles? or risks?

 

XTU must be installed first in order to unlock Throttstop, if not TPL is grayed out, the difference for me is that the multiplier stays 32 and the clock modulation 100% all the time.
With XTU I get fluctuations and it drops to 31, also Xtu triggers compatibility mode in W7 fills the registry with junk.
Loading the defaults in the Bios locks throttleStop again, forcing the multipliers,clock modulation,clock chipset,enable or disable Turbo doesn't work anymore but with my guide everyone can uninstall XTU without leftovers and use the benefits of ThrottleStop.

 

There is a single lock bit for the Turbo Power Limits register within the Core i CPUs. As far as I know, once this lock bit is set, ThrottleStop will not be able to adjust the TDP values. It is usually the bios that locks this register so it can not be changed after you boot up. It could also be locked by software such as a driver.

If loading the bios defaults locks out ThrottleStop TDP adjustment, is there some item in the bios that you can toggle on or off to control this bit and the adjustable TDP feature without needing to install XTU?

I am not sure what the bios looks like in these laptops but maybe have a look in the section where power limits can be set if that is available. Compare this screen in the bios to when ThrottleStop TDP adjustment works vs when TDP adjustment is locked out.

 

That was my first step besides TDP settings were all the same, perhaps it's hidden foreseeing unlocked BioSs.

 

Found it : Turbo power limit MSR lock >Disabled.
