Acer Aspire 6920G - Throttle FIX!

Please check the Definitive Guide for an improved explanation.

Well, we have so much discussion on AS 6920G that would throttle(CPU) like crazy. Many AS 6920G users in the world doesn't know it is the CPU actually downclocking instead of the GPU. So, now, get to know about it. I highly believe the culprit behind this problem is Acer themselves. They provide some lousy BIOS setting which basically trigger the processor to throttle when hit certain temperature(LOL about 57.5C which is damn low). Moreover, the lousy BIOS setting is LOCKED! However, Tehsuigi claims that there is another possibility it is caused by thermal sensor thingy.
Now! I found a way to stop THROTTLING permanently!
RMClock is needed for doing this. Download it at, http://cpu.rightmark.org/download.shtml
Guide of RMclock(it is a downvolting guide but it teaches the basic function or how to use RMclock), http://forum.notebookreview.com/showthread.php?t=235824
This tweak/solution is basically for AS 6920G. However, other gemstone blue model seem to be work with this solution/tweak as well.

Before you start this tweak, make sure you know how to function RMclock. Please do set RMclock to Maximal Performance(FID) with lowest voltage(VID) you can apply(without Blue Screen of Death or randomly restart of the laptop). I do not suggest Performance on Demand. To increase the effectiveness, please do clean up the dust.
For Core 2 Duo T8100 2.1GHz users, please set your FID = 11.0x(it is actually 10.5x but RMclock does not have "0.5x" wording, I explain like this might be easy for newbie) and VID = 0.925V

Then, go to your RMClock folder. Find RMClock_Tweaks. It is a Registration Entries file.
Apply it.

Solution/Steps:

1.) Enter regedit(registry editor, click Start button, type in regedit and press enter).

2.) Ok! Now, find UnlockEIST, IntelPMP4.EIST, UnlockFid, UnlockVid and UnlockTM2 to value 1. Basically, the original value is 0.

3.) Then, find CpuTempOffset. Open it up. You would see something like "000 00 ." inside CpuTemOffset, set it to "000 05 .". Please don't included the "". RMclock reads Penryn Processor temperature 5C lower than the original. Changing this value would show a correct temperature. This is trustworthy, Real Temp 3.0 and Everest Ultimate Edition both shown the processor 5C higher than RMclock shown.

4.) Restart your computer and have fun. Make sure your RMclock is turn-on(can set the RMClock to start automatically for every boot-up), if not, it won't work. You're not totally done yet.

5.) To improve the reliability of this method, please follow this, http://forum.notebookreview.com/showthread.php?p=5629246#post5629246
With the Power Option tweaking, the throttle point will be set higher slightly too. Done.


Advantages of this method:
a.) Throttle gone(not sure work for everyone since there're no 100% fix currently).
b.) Accurate/true temperature reading for T-series(santa rosa/penryn) processor.(+5C)
c.) Lowered your Power usage(prolong battery mode).
d.) Lowered your CPU temperature(might lowered the GPU temperature too because GPU and CPU share the same heatsink).

Test of Stability had been conducted(myself):
a.) Left 4 Dead-ing for 1 hour and no throttle occurs. Usually, it occurs around 10minutes. But now nothing happen.
b.) Orthos CPU stress for more than 3hours without a single problem.

Getting problem or this tweak didn't work? Follow this:

To those who can't perfectly uses this tweak/tricks, please do not panic. Kindly undo the registry tweak ONLY. Then, follow this semi-fix tweak. I copied this from Tehsuigi's topic(I lazy to type all over again, beside, Tehsuigi's English level is better than me).

Important Notes:

Additional Step(I think this tweak only work for half-multiplier processor but it is harmless to try):
Disabling Pop up mode and Pop down mode in Rmclock Advanced CPU Settings > Chipset. This may decrease CPU load and may lower the CPU temperature while idling.

Extra information:
Some people said their AS 6920G have poor gaming performance.
Download the latest Nvidia Geforce Forceware from Nvidia website, http://www.nvidia.com/Download/index.aspx?lang=en-us
Download the latest DirectX from Microsoft website, http://www.microsoft.com/downloads/...38-DB71-4C1B-BC6A-9B6652CD92A3&displaylang=en
Install them of course. You would notice a huge performance improvement on gaming!

To those who're interested on more advance method and dare to try more:
Moral Hazard and Weinter were trying to create some fixes to cure this problem.
They're modifying DSDT and BIOS in order to solve this problem.

DarkSilver, keep in mind that all of these settings are included in the RMClock_Tweaks.reg file in your RMClock directory.
Just set them there, and merge it with your registry. No muss, no fuss, and less chance of boogering something up.
I'll test it out later.

 

What you mean by merge it to my registry?
Of course I know these settings are included in RMClock_Tweaks.reg.
The RMclock REG is already inside my registry editor long time ago because of RMClock_Tweaks.reg(I double click it and it fused itself to my registry and this is a pretty common stuff for RMclock).

Last time, I don't know what all the settings for. A few weeks ago, I got some info(EIST,TM1,TM2) on what they actually do. So, I conduct some experiments. After all, I successfully find out this solution and it works!

 

I think TehSuigi meant that you can make the modifications in the RMClock_Tweaks.reg instead and then just run the file - it will "merge" the settings(from the file) with the registry.

 

So, he meant editing the RMClock_tweaks.reg 1st. Then, only merge it to the computer?
Can be done as well. The result is the same.

 

what ATG said xD

trying this immediately when i wake up tomorrow... if it works... awesome! ^^

 

Anyone test this out on the 6935g? Not that i've heard of anyone else with this model having a throttle problem :/

 

Try yourself. This is just some registry trick on RMclock to make your EIST disable. With EIST disabled, the throttle(throttle is set by TM1 and TM2) setting can't be use. Even Acer set TM 1 and TM 2 and lock them to prevent us to change it.
But once EIST disabled, TM 1 and TM 2 can't be use anymore. So, your computer won't throttle anymore.

Currently, max CPU temperature I get is 60C(if you do not +5C using the tweak I suggest, then it wil be 55C but it is a wrong reading).

So, it is proven that EIST on the BIOS play important role on this THROTTLING stuff.
Acer lock and invisible the EIST function in the BIOS and caused such a disaster.

 

OK, I made the reg tweaks and it throttled on me again after 30 seconds of ORTHOS.
Did you do anything in RMClock itself to stop the throttle?
(and even after using the registry edit, the box to disable EIST is still greyed out)

 

I think I need to show everything I have done.
EIST is greyed out as usual. Before that, I want to ask you, did you follow exactly?

Take note that do not change your processor codes. Your processor codes is not same as mine because different in model.
*warning*

 

not got my laptop on me so i cant test. posting with psp

 

do i have to undervolt the cpu before i do what you said?

 

Of course, you need to undervolt it 1st(you may do my tweak 1st too but later you need to undervolt it to prevent high temperature that may reduce the life-span of your CPU). So, the maximum temperature that your laptop goes would be lower even after EIST disabled.

Tehsuigi please read back the 1st page of this Thread, I have 6 attachments there.
These is the other 5, I have no problems running orthos more than 15minutes. I haven't try out 60minutes but I think no problem for me because I try to play Left 4 Dead for 1 hours and no throttle occurs.

 

and has anyone of you had problems while undervolting?

 

Just follow the step provided by flipfire. You won't get wrong. If you find BSOD while adjusting the voltage(basically too low), just restart your computer. Everything will be fine.
LOWERING VOLTAGE = HARMLESS
INCREASE VOLTAGE = HARMFUL

Flipfire undervolt guide, http://forum.notebookreview.com/showthread.php?t=235824

EDIT: To all, Please read the 1st Thread again. I added IntelPMP4.EIST which I forgot to include.

 

OK, I just did about 2 minutes on ORTHOS with no throttling...on battery.
Probably doesn't mean much b/c my GPU's PowerMizer is keeping it nice and cool, and not contributing to any thermal alerts.

 

LoL? Have you done tweaking all the stuffs?? I edited the 1st Post. You read it carefully and follow all the steps. Surely you can do it.
DO NOT USE THE REG FILE and merge it to registry.
Just use the regedit to edit it.

Meanwhile, I am orthos-ing. Now is 47minutes(haven't throttle) and 54C only.
I need to try 1hour. XD! God bless me ~~~~ If I can survive more than 1 hours which mean I successfully get rid of THROTTLE! YEAH!! Actually, I already know I get rid of Throttling a few hours ago by L4Ding for 1 hour.

 

Haven't made the PMP4.EIST reg edit yet, nor have I verified my registry with yours (kinda in the middle of something right now).
Trust me, I got this. :3

If this works, DarkSilver, I can't give enough REP.

 

plz reply as soon as possible.....
is it possible that even at the least undervolting i can reach using rmclock(i.e 1.0500V) i dont get a "bsod"?
and also at this voltage i get a max temp of only arnd 44C...
does that mean it has eliminated the throttling(because i think somewhere someone mentioned that it happens when the cpu runs at above 50C for few minutes)??i have been running orthos for about 1 hour and simultaneously decreasing the voltage and no bsod upto now?

 

Switch44, it's entirely possible that you can run your CPU at that voltage. But if I were you, I'd go up a step or two just to be safe, and run ORTHOS for an extended period of time (3-4 hours) just to ensure rock-solid stability.
(also, don't forget to do short tests on the intermediate multipliers!)

 

so if i go up say 2 steps then for the intermediate multipliers i try out voltages less than what i set for the max right?

 

I can get 0.925V(I always change the VID for fun LOL) as lowest.

But I don't think 44C is your max temperature.
Reasons,
a.)Orthos stress CPU slowly, 1 hour is not enough. Meanwhile, I am stressing my CPU to at least 2 hours.
b.)RMclock would read 5C lower than original temperature for T-series(santa rosa/penryn) processor. That's why I included that tweak(+5C) on this Thread.

Additional testing method,
Try some 3D intensive game such as Left 4 Dead, Crysis, Assasin Creed, TF2 and so on for 1 hour or 2 hours. If you find your machine does not throttle after 1 or 2 hours of 3D intensive gameplay, you're done. Your machine is sucessfully get rid of Throttling.

Simple method to use RMclock:
1.) Select Maximal Performance profiles, set it to the highest FID(do not choose FID if you're not using Half-Multiplier Processor).
2.) After that, go to the main profile tab. You can see On AC and On Battery, Current and Start-up, all set to Maximal Performance.
3.) Then, ticks all the index boxes below it, except IDA(unless you're using Half-Multiplier Processor).
4.) Select a certain VID value on the highest index(not IDA unless you're using Half-Multiplier Processor).
5.) Try all the VID value provided there until you get BSOD. If you get BSOD mean that VID value is not suitable for you and you can't go any lower.

 

nope no tweak...
mines a t5900 2.2ghz
yea it seems like the temp is going up...right now its reached 48C....
so if it still stays below 50C it means i dont need to do the registry stuff right?
the intermediate multipliers will be less than the max multiplier right?

 

Switch, ask these questions in the Undervolting Guide thread. Let's keep this thread for throttling and the possible fix.
DarkSilver, certainly sounds like you've solved your problem. I'll be more than happy to give it a whirl and cross fingers and toes that this fixes it.
(and also thank you for giving me an excuse to play TF2 for the first time in weeks)

 

T5900 is not a Half-Multiplier Processor so you don't touch IDA.
There is no assumption said that below 50C = Won't throttle.

Please do read my previous post, I edited it.

 

Ooooo yeah. I am still Stressing the CPU.
How about you? Have you done? Please send me your MSN address or whatever messenger address that you use via PM. Replying here is very slow. In addition, I can ask you questions there easily.

 

OK, I've made the changes you mentioned and confirmed my registry with yours (PMP4.EIST already showed up as 1).
Time to reboot and see if I got this.
EDIT: Nope, still throttling in under a minute. DarkSilver, my MSN name should be in your inbox momentarily. Let's figure out why mine doesn't work but yours does.

 

Conducted 3hours of Orthos CPU stress test.
The CPU still do not throttle with temperature of 53-55C.

 

hey ive gt a prob...i cant find cpu tempoffset value...it dusnt exist n ma registry.....i searched and all but its not there

 

in fact none of those values mentioned above are there...do i have some old version of rmclock or sumthing?

 

sorry people...i had to just add the registry tweaks file to the registry....

 

have you run RMClock_Tweaks.reg in the RightMark program folder under Program Files (or wherever you installed it to)?

btw.... i seem to be in the same boat as Teh Suigui... it is still throttling after the regedits and restart x)

 

yea sme here.....its throttling durin orthos....did the entire reg thing....
hey darksilver...the screenshots youve posted the second time....does it have to be the same?
becoz when i change some of the settings on mine to match that of yoursthe comp gets stuck....

 

have any of you tried using custom settings on orthos?
i tried it with min fft size as 192 and max as 10240....it starts throttling quite soon then....

 

I think I know the problem already.

@Tehsuigi,
Maybe you use MS W Vista Ultimate x64, that might be the case. Try reinstall MS W Vista Home Premium x86 and try this again.
But I think your case might be same as Switch44. Please take a look below.

@Switch44,
I think you need to choose IDA as your highest index FID in your maximal profile and use it. I can run Orthos on all different settings without throttle.
Now follow this,

 

I having the same problem even i do it according to what you said in the first post.

I run Othros for almost 4-5minutes then its start to throttle. But when i running the Othros, my tempeture is almost 55-60C. Is this normal?

Any help please. Thanks.

 

Uh no, I'm not going back to a lower operating system - I paid for this Ultimate upgrade, and I'm going to use it!
And I'm also not moving back to 32-bit. 64-bit is just too awesome.

 

Mmm what about going to windows 95?

 

LoL?
Windows 95 can't be install into your laptop I think.
This is because the hardwares do not match with the softwares.
Now, I am wondering why you all can't fix the problem. Maybe I could use 0.925V and you all couldn't? So, is that the problem?

 

it could be because of different processors?

 

Well my 6935g seems fixed after it came back with a new fan. Some mirror's edge with fraps recording in the background for a bit and didn't throttle but test wasn't long enough to know it won't happen.

nvm it did. Though now the fan is acting weird. It turned on max when playing a game and wouldn't slow down afterwards. Now im using Orthos and temps are higher than they've ever been yet the fan in on minimum :/

 

Oh, and DarkSilver?
Whatever changes you suggested for my RMClock were...not helpful. I started getting random system freezes, failures to hibernate, etc.
I wiped all the RMClock entries from the registry, and put the thing back together how I like it.

Not like it matters that much anyway - today's the big day!
Wish me luck at Acer HQ.

 

Good luck!

btw DarkSilver i couldn't find CpuTempOffset in my registry. Started going through the undervault guide and at first it would thottle at 7mins with Orthos (though mirror's edge + SF4 would throttle a lot quicker) and my first voltage down now and going at 20mins+ now! So hopefully this will be enough to semi fix it.

 

So, the new fan fixed your problems? Well, you can undervolt your laptop to lower the temperature. It doesn't matter you can't find it since your problems fixed.

@Tehsuigi,
Good Luck! Pawn Acer!!
As for the rmclock tweak, I got all benefits but you got all nightmares. What a contrast.
Never mind, every cloud have a silver lining. You would fix it soon.

 

I thought it fixed my problem but it didn't. My fan is quieter now but it still throttled in the end.

The undervolt seems to be helping a lot though with Orthos anyway. When i find the lowest stable volt i'll test it out with real games. If not i will phone/email Acer again.

 

yeah.. same here.... random system freezes and stuff.... but Good luck with Acer!

 

Dark Silver,

I follow every setting that you given, including those picture's. I finally done, but 1 problem is, everytime i restart or shut down my computer, its hang. Any clue? >.<

 

Don't copy my all my registry. Because some of them are for my laptop only.
See the 1st post on this topic, those are real tweak. Currently, I have no clue on why other machine can't use this method.
Those registry screenshoots were mean for Tehsuigi(acer chaser).

 

I followed the registry setting on the 1st post. But then i dunno what to do with the setting in Right Mark CPU Clock Utility. My laptop is the same spec as yours, means i can use the same setting as yours? can you upload picture of your setting here for me to refer? Thanks.

 

Read this page(my rmclock setting), http://forum.notebookreview.com/showthread.php?t=393073&page=2

Please enable IDA on the Advance tab. In the attachments I shown on the previous page, I forgot to include it.
Please use Maximal Performance profile(set yours to 11x FID and 0.925VID).
