Acer Aspire 6920G - Throttle FIX!

Can't agree more, they have affordable price and super awesome performance. anyway the throttle strikes back... sigh. after i turned on my laptop this morning and run the RMclock it seems on the "throttling tab" the Greyed "Force Thermal throttling" was ticked even though i didn't touch anything after yesterday success. but i think i was on the right track, gonna share it when i achieve the "TRUE" success.

 

I would like to suggest that after you done a TRUE tweak using the RMclock registry. Export the whole RightMark registry folder out. It would be a Registration Entries. Rename it to something like My True Fix.

When the throttling tab or whatever greyed out and cause the throttle to strike back, delete/wipe out the RightMark registry folder. After that, apply your My True Fix.

I know some of the changes can't be made in RMCLock. The RMClock would revert it back. I guess this is due to Acer BIOS(locked) which blocks RMClock features.
For example:
I have my IDA disabled in RMClock manually(not in the registry). It works for the time but everytime I restart, it would be IDA enabled(it doesn't tick on the box). Yet, it is enabled because when I press Refresh, the IDA got ticked.
I tried to disable IDA using registry, the result is the same. IDA enabled again after a restart.
So, I always have to disable IDA everytime I reboot or start my laptop. Luckily, it is not harmful LOL. It just gives unstable FID(raise 10% and revert back to normal) and VID(raise 10% and revert back to normal) every few minutes.

 

yeah, sometimes the set up keep changing just like that without any warning.. i think that's where my problem lies, pretty much i'm suspecting on the Greyed "Force Thermal throttling" was activated one way or another .

 

*darksilver
I just wanna ask you simple thing. Do you advice to use "disable power mixing". Can it be change something about gpu performance?

 

I don't see how the Acer BIOS could "control" RMclock settings...the cause is more likely in the old and no longer supported RMclock software which appears to get "bugged" in certain situations. Anyway, did you try to make RMclock folder(and all the files in it) read-only?

 

but unfortunately the current RMclock we are using is the latest which is 2.35. Pardon my ignorance, but what's the purpose of turning every files in RMclock folder into read-only?

 

Yeah the support(and future developing) of RMclock has been suspended a long time ago with no indications of coming back..in near future anyway.


According to DarkSilver(check his posts above), something is causing RMclock to change its settings back(enabling IDA). Well, by making all files read-only this shouldn't happen, nothing should be able to make changes in the settings...

 

I would try ATG method sooner or later.
Agreed with ATG, RMClock 2.35 is the latest but is an ancient software(the develops have stop the update/patch) LOL.
And onur83, the GPU performance is controlled by PowerMizer.
PowerMizer is controlling the GPU speed. When you're not gaming, it would reduce the speed and save battery life or electricity. While you're gaming, it would max out its speed. In short, it is a very nice technology.
Just that my laptop have some overclock issues with PowerMizer enabled. So, my PowerMizer got disabled.
What I do is create my personal PowerMizer(create many profiles of speed/clock of GPU and order the profiles to take action in different situation).
For example:
Increase my GPU speed to maximum(i set the value) while I play these games/applications and decrease my GPU speed to minimum(i set the value) after I quit these applications/games.

 

or rather download "Powermizer Switch" it will help you enable or disable the powermizer either on AC or Battery or both. Yeah last time i was having downclocking problem as well that made me to keep changing the driver from laptopvideo2go.com and when i'm done with the GPU issues which is downclocking, now the CPU issues appeared which is Throttling, what's next??? DownThrotling?

 

Once you change the setting using PowerMizer Switch, you need to restart your computer to take effect.
I do not use PowerMizer Switch, instead I use Nv GPU Pro.
This software is much better than PowerMizer Switch because it has more selection and function. Together with Nvidia System Tools(nTune), my GPU is running great now with my overclock. XD!

Not DownThrottling, I guess is HDD throttling LOL and keyboard and mouse throttling XD!

 

dude do i have to put rmclock as a startup for this to work?

 

I'd only do that once you've got your stable undervolt. That way, if things go sour and you BSOD while stability testing, you're back to your stock voltages on reboot.

 

If your system is OK and stable already. Then, you should put startup for RMClock. I guess you have done(success) it right? I mean my throttle fix tweak.
If you have success with the tweak(you seem have success with it if not mistaken) and the system works well, RMClock for startup is a good choice. So, you don't need to click on RMclock to launch it everytime system reboot.

 

Hi!

just got a new 6935g and i think i also have the throttling issue. (FPS drops and the sound gets choppy after few minutes of gaming)

will this tweak also work on a 6935g?

 

Yup - the 6935G got hit by the same bug.
Check the Definitive Guide to Gemstone Blue Throttling for more info.

 

Follow Tehsuigi's advice.
If his solution fails, then come back to me again.
Actually, this thread(my thread) is connect to that thread(tehsuigi thread).

 

ok ive got a blue screen on lol better get more volt i put it at .925 like yours and got that also the registry tweak makes my laptop more slower :S dont know why( if i put it as startup) but when i open it without it is still normal.....

 

Well, like we said, no solution is one-size-fits-all. If your system runs better without the registry tweaks, remove them!
And not every CPU can drop to 0.925V stably - not sure if DarkSilver mentioned that in his guide.
Start 0.1V lower than stock, then keep dropping every 5 minutes of ORTHOS until you hit a BSOD. Then go one or two stages above that and give it a 3-hour stresser.

 

Agreed with you. You just save me from explaining these stuffs.
Basically, 0.925V may not be stable on many processor. Usually, Core 2 Duo T8100 2.1GHz can use it(0.925V) but there are exceptional too. Even the same model and brand of TV have different colour gamut due to its amount chemical substances have slightly different.
Lastly, I have 0.925V as my stable voltage.

 

ok sorry for my dumb question the semi fix works but i want to get more inside of this its addicting XD!

 

I believe your CPU's undervolt is the exception, not the rule. Most CPUs can undervolt 0.1V below stock, not all the way to the minimum voltage allowed!

 

You can tweak around RMClock registry yourself. Be confident to explore on your own. If something goes wrong, just wipe out the RMClock Registries Entries LOL.

@Tehsuigi,
It seems to be my undervolt are quite crazy. LOL. But some T8100 users are able to undervolt to 0.925V too according to this topic's replies. However, I agree with you it is quite rare to have such intense undervolt.

 

now stressing my P8600 at 0.9875v @9x. looks stable *i hope*

 

wow! i think throttling is gone!!!!

tried benchmarking and playing crysis for about an hour and throttling didnt occur!!!

thanks Darksilver!!!

 

P-series Processor have much lower Voltage Usage. You can try undervolt it slowly without having unstable system such as BSOD or randomly shutdown/system freeze.
I just love P-series Processor LOL. Much more cooler due to low voltage usage and faster in FSB!!

 

Actually that is not true, at least not in all the cases.

My T7500 is running 0.1V below my P8600.

 

I know. I just mean basically and usually P-series uses less voltage.
Of course, there are exceptional.

 

i have no throttling issues with as6920, so i want to know what is the default max temp. for the cpu that it undergoes without throttling? what about gpu?

 

In theory, the CPU is supported to reach up to 90-95 degrees Celsius before it downclocks, but for models that throttle, it's closer to 58.
The GPU downclocks around 90-100 Celsius on all models.

 

check out this realtemp log

this happens when i play far cry 2 (00:08), at some point (maybe at 00:14) in the game i experience fps drop. could this mean cpu throttling? i've noticed that the load% is cut in half, what does that mean?

this happened to me in burnout paradise. i've used orthos for 1 hour, and there was no throttling issues

how can i know whether i have a throttling problem or not? could it be a memory leak or something?

 

my laptop frezzed and it doesnt what to startup either i was undervolting looks like .975 is for me i putted .950 and didnt bsod just freezed

 

hna: Please check the Definitive Guide for how to diagnose a throttling issue.

metalroses: That can happen too. What do you mean, it doesn't want to start up?

 

black screen i just turn on the laptop and it stays on it

 

...that's bad. I know I botched up my Windows install once through undervolting, but I was playing TF2 when it hit.
Go download the Vista Recovery DVD and let it do a startup repair of your system (or System Restore). I remember it was able to get me to a usable state.

Oh, and did I mention that backing up on a regular basis is crucial for times like these?

 

Undervolt until can't start-up!?
That's strange. LOL. Because RMClock only take effect after windows boot-up(after it appear in the taskbar).
The blackscreen might be caused by system corrupted I think.

@Hna,
Tehsuigi's right.

 

Cut the power so the CPU Voltage registers will reset.

 

i've attached a log file from rmclock. at abt 11:47, i noticed fps drop down playing far cry 2

 

LOL! I noticed my AS 6920G even without undervolting or whatever, sometime, it can blackscreen too(during boot up). I already familiar with it since the 1st month. XD!
That time I thought OMG laptop SPOILED!? Then, take out the battery and remove the AC cord. After that, I plug-in the AC power again, everything work fine. LOL.

@hna,
Undervolt can cause FPS drop for some games. My GRID run slightly lower FPS(1-3FPS drop I think) with undervolt. However, some games still run as usual.

 

the black screen on startup happened to me once even before installing rmclock. i really dont know the reason what caused it. i tried vista recovery methods but it didnt work. i was forced to reformat my laptop because of that.

i experienced throttling again on 0.9875v when i didnt use my laptop cooler. but when i put my laptop on my cooler even if the fans of the cooler are off, i didnt experience throttling. i guess elevating our laptop helps a lot.

 

i still haven't undervolted. i'm just diagnosing if i have a throttle problem, i've posted a log above.

 

so mine does throttle... i've noticed it thru rmclock, its' cut in half (from 1995 throttle to about 900) weird thing is that it doesn't happen in orthos.

 

@hna,
LOL. It is throttling obviously.
Have 2 reasons why it doesn't happen in Orthos,
a.) Orthos test not using FFT small blah blah
b.) GPU not heated up(due to no 3D gaming), so, the heatsink is quite empty and can absorb a lot of heat from CPU
@Vinch,
I guess your laptop can't support intensively LOW voltage supply.
You need to find yourself a stable one.
Just now, I tried to play The Sim 3 for 2 hours.
I got no throttle with CPU temperature 60C and GPU temperature 70C.
I am doing experiments on the TM 1 Throttle Kick-In value.

 

yeah i thought it's due to heat coming from gpu also.. another thing is that it doesn't happen in other games (like sims 3 for example)

 

What games are you playing?
But The Sims 3 seems CPU intensive too.
Try Left 4 Dead? Last time, my CPU start throttle about 10minutes with Left 4 Dead. LOL. So, I actually use Left 4 Dead as my Throttle Test XD.

 

i used to play it months ago, it didn't throttle!

also, are the rmclock temps wrong? cause it reports a low core temp compared to that in realtemp.

 

Of course. Real Temp 3.0 is better on monitoring CPU and GPU temperature.

 

LoL! Thats my throttle test too. This is the game where I last experienced throttling. I never experienced throttling in Crysis, Burnout, SF4 and other games since I did the tweak.

Dont use Orthos for throttle test, use real games like.....

Left 4 Dead. LoL!

 

yeah ive got backup but it doesnt even start doesnt do anything gonna try taking off the battery. and your laptops runs crysis? do you have the aspire same as ours?

 

I guess it is a total destructive of HDD files.
Did alt+F10/alt+F8(restore to factory default) can be apply?
If all the recovery/system backup stuff can't be done. Then, you should do a re-installation of OS either using eRecovery(alt+f8/alt+f10) or a D2D eRecovery Disc(OEM) or a Windows Vista(normal not with Acer junks).

 

Total destruction of hard drive files? Bollocks. It's more likely a loss or corruption of the files needed to boot up.
Did you use the Vista Recovery DVD I mentioned last page? That should fix any problems with an unbootable Windows.

Wait, what do you mean it doesn't even start? Does the fan turn on, does the hard drive activate?
