Acer Aspire 6920G - Throttle FIX!

LOL. That was exaggeration only(about the destruction). Not so serious. I know it is only system/boot up files corrupted or errors. I have experienced it a few times before(long ago).
If the CPU, GPU, HDD, RAM and Power can be turn on.
1 thing left to do would be re-installation of OS(D2D OEM, Clean Vista or Whatever that will do).

 

every seems to be on but just black screen and im going to try that dvd recovery now so i tell ya what happened


EDIT: ok... now it started up like nothing.. thanks for the help guys im keeping those in case if happens in the future

 

Congratulation.
LOL. I need to edit this reply. Because I saw something wrong with my eyes.
Now, are you still undervolt and no throttle?

 

Good to hear everything's fine - what was the last thing you did before it got fixed?

 

yup no throttling for now even in day with undervolt as i said 0.975 its for me nice dude this is awesome gears sf4 wow and other without problems thanks man! you are the best.

 

nothing it just randomly worked. thanks again for helping tehsuigi and darksilver

 

However, I plan to raise to 1.00V because I gonna disable the DFFS setting.
I can get more FPS in games with 1.00V.

 

Which doesn't make any sense, as more voltage doesn't improve CPU speed. Stability yes, temperature yes, but not speed.

 

I guess it is due to full stability? I mean like if I am using 0.925V, maybe the CPU would drop it speed due to instability for like 0.5seconds then raise back to normal(I noticed it sometime but not everytime). With 1.000V and DFFS setting disabled, I got a full stable CPU.

 

Hey, whatever works for you.

 

Frustrated? LOL?
I haven't completely testing it. I guess I might test it sooner or later. If the throttle kicks in with 1.000V, then, I should turn back to 0.925V.

I noticed the CPU load increased with DFFS disabled.
Actually, what does CPU load do?

 

CPU load is just how much work your system is doing.

 

Would that be suck?
How about OS load?
CPU Load and OS Load really confusing =.=!

 

CPU load - how much work your CPU is doing at that time.
OS load - how much work your operating system is doing on your CPU.

It's like checking in your Task Manager - neither good nor bad, just an indication of how busy your CPU is.

 

yup no throttle at all with undervolt why do you aks

 

I thought the undervolt spoiled your laptop. So, I ask is the "undervolt help you to avoid throttle?" If it is, then, it is a good thing.
This guide is not very stable already. Many reasons behind it. Even myself have some hard time on it. However, the throttle is gone with this tweak, just that there are some minor stuffs(bugging me).
I will try 64bit OS sooner or later. Experiment is needed. LOL.

 

oh ok and yes undervolt helps me avoid throttle

 

after doing this tweak throttling is gone on my laptop but still there's only 1 game that's making my 6935g throttle. that is Left 4 Dead!

 

Because Left 4 Dead is CRAZY. LOL.
I don't know why this game seems to use the CPU recklessly and brainlessly.
I have play higher end games than Left 4 Dead but Left 4 Dead uses more resources than the other. LOL.
However, I didn't throttle with Left 4 Dead with my tweaks.
I will update some new information soon on why Windows 7 can delay the throttle to kicks in or avoid the throttle. ^^!

 

i remember on my former 5920g laptop its 8600m gt reach 94c when playing that game! i guess its because its too many enemies for the cpu and the gpu to process.

just installed fallout 3, played for hours and no throttling at all.

 

The build of Left 4 Dead maybe a little crazy and it recklessly uses the GPU and CPU. My friend's laptop always got 100C on CPU when playing Left 4 Dead and after that, the laptop shutdown due to overheat.

 

Same situation for me, normally no throttle but when i open that game its throttling. what a game. I deleted it already hehehe. Then throttle's gone.

 

Today is a BIG day for me to test Windows 7 RC x64!!(RTM quite boring due to the deadline) I might install Windows 7 RTM x64 if I have cr@ck(my frenz got it already ).
Stupid 32bit OS can't let me make my USB flash drive into bootable flash drive for 64bit OS. Need to use CD to install windows 7 RC x64 T.T!

I will test Windows 7 for the throttle stuffs. Rumour said Windows 7 uses less resources(CPU and RAM) which can reduce some temperature. Some even said can prolong the battery life, this mean it might use less voltage as well. lower voltage = lower temp!!! ^^!

 

^nice! keep us updated

 

I don't think it will make a difference concerning the throttling issues, I'm running Windows 7 RC and the CPU still managed to throttle. However, I am using the x86 version so maybe you'll have more luck with x64

 

I am already on Win 7 RTM Did the modding myself

 

Well, I am rolling back to my stock OEM Windows just now. I have a headache on Windows 7 RC 64bit(left4dead can't be play, my private battle.net stuffs all can't be play, some softwares that I love can't be use). But I can see that the voltage usage(nice EIST build perhaps) is reduced on Windows 7. The temperature is slightly lower due to that.

I will give another try on Windows 7 next time. I think I should get the cracked RTM of windows 7 from my friend and try it. I am quite lazy now. I got whole day sitting and tweaking the windows 7(for it to use or play older games). Lastly, I gave up. LOL. Now on Vista HP SP 1(I don't like SP 2). Busy installing back all stuffs. LOL.
I will see how my RMClock works on Vista SP1. XD

EDIT:
OPS is my fault for the left 4 dead can't be play on windows 7. LOL. It can run on Windows 7.

It seems Acer VCM and the BIO finger print stuff give instability(using 0.925V) to my laptop. I got Acer VCM and BIO finger print stuffs uninstalled before I install Windows 7. I noticed 0.925V is not stable after that. After a few days, I installed Windows 7 and now,
I roll back to stock OEM Windows Vista x86, after I tweak everything(delete bloatware, vista tweak, and so on) that I need, I purposely left BIO finger thing and Acer VCM, and test the stability using 0.925V. It is stable. ^^! So, I just ignore them being in my laptop for the stability using 0.925V(never use them even once LOL).

 

DarkSilver, I followed your guide and my 6920G works like a charm. Thank you so much, now I can play TF2 again!!!

 

tried playing fallout 3 then suddenly it shutted down w/o showing some errors or blue screens. turned it on again and i noticed that the battery is drained. what surprising is my laptop is plugged on a AC outlet. is it because of too low voltage settings? im running on 0.9750v on maximal performance.

-edit-

is it because im using a different ac adaptor? im using 19v 3.24a adaptor.

 

DarkSilver if you need any help just ask i've already installed windows 7 rtm x64 on my AS6920G and everything is running fine. I've also noticed fewer throttling issues without undervolting and with it the CPU cores idle at about 11-15 degrees (pretty cold even in a room with ~20 degrees temp)

 

I have this problem even I am not using RMClock(downclock) but this problem only occur to me while I am shutting down the laptop.
The symptom is like: I already pressed shutdown, then the screen goes black after finish saying "shutting down windows and all kind of stuffs" but the power is still ON. It is not hibernate or sleep due to it can't wake up and the power LED light is not blinking but is light-up all the time.

After pressed the power button long enough to shutdown the laptop, I turn it on again. I see the battery has been used for about few percent.

I think you should play Fallout 3 to do the experiment.
If the laptop goes bluescreen or restart or shutdown itself while playing Fallout 3 everytime, then, it should be VID too low for it.
If it only goes bluescreen or restart or shutdown itself seldomly/rarely while playing Fallout 3, then, it is not a big problem.

 

TBH i haven't tried running fallout 3 yet, though i will when i get back from my vacations (that is if that post was addressed to me )

For your problem, is it win 7 you're talking about? I had no problem with shutting down ever in vista of seven. Try removing the battery and then shutting down, see what happens.

 

Nope, not Windows 7 fault. I am not sure it is Vista fault too. It happens naturally and rarely. I think I experienced this 2 times only for 15months.

I am experiment something too. I found Windows XP and Windows 7 runs better Prototype. I think it is due to the device manager HID stuffs. Windows XP has only 1. LOL. But Windows Vista has numerous. T.T I already disabled all except keyboard and mouse. Yet, it still sucks. After some research, I found there are some hidden HID too. However, I can't disable them. LOL.

 

Well HIDs are those buttons acer put on this laptop like internet launch, the epower button etc so removing those may not make any difference.. What bios are you running on? Also did you try installing the chipset drivers and matrix storage manager from intel?

 

changed my adaptor to 4.74a from 3.42a, problem is gone.

played fallout 3 for hours didnt get any problems at all.

 

So you are suggesting insufficient power caused the throttling?
Can someone else test this?

 

Huh, I think it's definitely a possibility. Like running on battery...

 

Yep! I guess it is possible. But need confirmation though.
But how I know the Current(A) of the AC adapter??
However, it is silly too. Because we undervolt to much just to decrease the temperature(remove throttle) but you increase the voltage to remove the throttle. LOL.

Anyway, you're using 4.74A adapter with undervolt?
Or, just 4.74A adapter without undervolt?

 

I've been running on a 4.74A AC adapter since day 1 - that may not be the cause of the problem.

 

Well, I checked the AC adapter I use just now, it is 4.74Ampire too.
Later, I gonna check my Ancient Acer laptop AC adapter too.

I found out the instability(spiky graph) of FID and VID is due to the EIST.
If the programs/start-up/services/processes lessen, the EIST will start to act or force to act.
Without undervolt(C2D T8100 2.1Ghz stock VID 1.1375V):
EIST will decrease the VID and FID while computer is idling or very little processes. Basically, from VID 1.1375V and FID 10.5x to VID 1.000V and FID 6.0x because BIOS has set EIST to act like that.
With undervolt(C2D T8100 2.1Ghz undervolted VID 0.925V):
EIST will increase the VID and decrease the FID.
This is due to the BIOS has set the EIST to run 1V VID and 6x FID while idling/less processes. So, the VID 0.925V and FID 10.5x become VID 1.000V and FID 6.0x which is not convenient to see.
Raising and decreasing of VID and FID frequently caused spiky graph on RMCLOCK.
However, this is harmless. ^^! Since FID is 6x, it won't increase the temperature even the VID is 1.000V. Moreover, the FID will raise back to 10.5x and stay stable(max for T8100 with IDA disabled) as well as the VID will back to the VID you have set(mine is 0.925V) if you're running some pograms/software/games. Lastly, performance will not be affected while gaming and not gaming too.

 

guys
my cpu is not trothling at all...
staying on a constant 2395mhz on 1,000v..
but my gpu ...is trothling al the time...
shader 550
memory 100
core 230

how to solve that...
and where to disable powermizer?

 

This is not a problem at all.
When did your GPU throttle? Gaming? or when you're not gaming(listen music, surfing website, chatting and so on)?
If you're not gaming, the GPU will throttle itself to save battery life(if you're not on AC)/save electricity(eco friendly) and lowered its temperature(longer the life-span of the GPU).
If you're gaming, and the GPU throttle, then, it is a problem!

Disabling PowerMizer will cause the GPU to be MAXIMAL at all time. So, the temperature of the GPU will be higher when you're idling and lowered the GPU life-span.
Enabling PowerMizer will cause the GPU to adjust itself for the situation needs. So, when you're gaming, it will at MAXIMAL, when you're not, it will be lowered to reduce heat and longer its life-span.

 

So what should I do?

I just picked up an Aspire 9620g and been hearing about the issue.

I will be confirming if I have the issue tonight or not.

So I see there are two different ways of fixing.

One is to turn off the CPU throttling
One is to undervolt the CPU

Which one should I be doing?

I want the most automatic way. I am a tech I just don't want to adjust settings in mid-game.

 

Undervolting the CPU will prevent the throttling from being triggered in most cases - do that. Follow the guide here on NBR, test for stability, and make sure you've got a backup.
And remember, every CPU is different in terms of undervolting capacity. Just because mine can reach 1.000V doesn't mean yours can stably.
Check the Definitive Guide for more details.

EDIT: Speaking of which, it's pretty much solved my problem permanently. I've been encoding a video using HandBrake for about 90 minutes at full CPU load, and my temperature hasn't cracked 45 degrees.

 

Sorry i didn't see that thread before hand and I was looking.

I have to do some testing tonight, as I see no one is running or has atleast posted about Windows 7 RTM.

Also I'm running Windows 7 RTM, with some patches that might help the issue

 

I tested Windows 7 Ultimate 64bit RTM with RMClock(undervolt uses) before.
I work just fine. No problem.

Off topic:
However, I encounter some problem on SYSTEM FREEZING while using Battery Mode(plug off AC) even without UNDERVOLT with Windows 7.
I tried some methods, all fails. If anyone have similar problem on Windows 7, please tell as well. I wild guess is that the HIDDEN PARTITIONS of the Acer MBR(eRecovery).

Back to topic:
Follow Tehsuigi's advices.
To test or confirm that you AS6920G was throttling, you need to some monitoring tools such as Real Temp 3.0, RMClock(have it too), CPU-Z(information) and Everest.

Lousy method to check THROTTLING on AS6920G(fast and effective for newbies).
Reboot.
Play some games such as Left 4 Dead, GRID, Prototype and The Sims 3. These are CPU intensive and GPU(too) games. Run 1 of the games for about 30minutes or 1 hour. Check the FPS(smoothness/framerate per second) of the Games when the games just started and then, check the FPS again after 30minutes. If the FPS is lowered a lot, which mean the CPU is throttling. FRAPS(if not typed wrong) is the software to check FPS. Google and download, it is free.

OK. If you're throttling(confirmed), follow Tehsuigi's advices and do the UNDERVOLT(using RMCLOCK) and some other stuffs like cleaning up the DUST. If it still throttle, come back and try my method. I hope you fix the problem. >.<

 

I've no freezing, but I've made sure that all the Acer partions were deleted.

That above site has a massive patch list for Windows 7 x64 RTM.

These updates fix a few performance issues, and other bugs.

They will be hitting Windows update within a week or so, but we have access to them now.

I have ran into zero reboots, or bsods with windows 7. No issues on battery or AC.

But I do very basic installs, I keep it simple.

I'll post more about my build later.

 

Been running Win7 RTM with my undervolt and haven't noticed any of the problems DarkSilver is running into.
It's possible that Win7 RTM has fixed the throttling problem, but not exactly plausible if the issue lies with the BIOS or a borked motherboard sensor.

 

Well that I do understand.

Windows 7 may have better managment for such features for controling the CPU, and then would help reduce heat.

Now do we know if new models of the 6920g are affected or not?

I got my laptop from someone for cheap off Kiji and the it was made less then a year ago.

But the bios was outdated to 1.07v, which I placed at 1.14v; using a old dos usb boot stick.

 

Great link warwon, I think I will test them out while I am free.
I just installed back Vista Ultimate x64 and tweaked it as well as finish installing all software I need. Meanwhile, I won't install Windows 7 1st. I think I will install Windows 7 after sometime and test out the link you provided.
Thanks.
