The Definitive Guide to Acer Aspire Gemstone Blue Throttling Issues

i have the ability to monitor my temps with rivatuner, but i have not done so. maybe i am just looking for an excuse to upgrade ill do some testing and see if it does it at a specific cpu temp

 

errr?? You overclocked your GPU using Rivatuner?
Get something like GPU-Z to monitor your GPU temperature.
Clean your laptop, dust is your best friend.
If your GPU temperature is not beyond 80C or 75C and it is downclocking, then it is an abnormal downclocking issues.
I would suggest(well it is suggest only, is your choice) you to disable PowerMizer(Nvidia GPU) or disable PowerPlay(Ati GPU).
With PowerMizer/PowerPlay disabled, the GPU won't downclock no matter what happen. However, it would make your GPU stay at max speed even while idling. So, the battery would finish faster and the minimal idling temperature of your GPU would increase(1-3C) due to the GPU is at max speed.

 

ok, after testing, i do think it is a heat issue with the cpu, but its not the same thing your having. my processor actually reaches temps that would require throttling, so the upgrade should do the trick. sorry to interrupt your thread. good luck figuring this out.

 

Thanks!
I reinstalled RMClock (used RMClock_WipeOut to clear the registry) It works a bit better now but still doesn't recognise the chipset "Unknown (8086:2919)" & some of the greyed out options have changed values.
CPU Info reports Req.Vcore (VID) incorrectly as 1.0500V Minimal & 1.2500V Maximal (VID Voltage Range is 1.075V-1.175V for a Core 2 Duo T5800 according to Intel Spec's)
Disabling C4E seems to stop the Core fluctuating to 1.2GHz (didnt help the DPC issue but, still good to know)

This Acer Aspire 6930 doesn't seem to Throttle with Orthos running
(See attached images one with all CxE options enabled & one with C4E options disabled)

 

Cyberpunk, try changing the CPU Type setting on the Advanced tab in RMClock from Desktop to Mobile. That should fix the overvolting.
And yes, 6930s seem to be more immune to this problem than other Gemstone Blues. I've lumped them in just in case.

 

Hi all, first post here but i have followed the 6920G throttling threads for a while as i am myself another unlucky one with a 6920G T5750 and HD3650 with throttling issues.

So i've done everything, undervolted my T5750 to 12x and 1.025 volts and I still had some throttling, not that often though. Then I disabled the "Enable Extended Throttling" option in RMClock and guess what? No throttling! But...

After some gaming with GRID, my lappy suddenly shuts down! I did it again, only this time with HW Monitor running and I got 55 degrees CPU and 85 (!!) GPU! Needless to say I had already cleaned the vents from dust. Then shutted down again, unfortunately didn't manage to see temps since the game only runs full screen. By the way this has worked in Vista x32 and i only got that problem now that i installed seven x64. I'll try and get a reading of the temperatures though when it shuts down, i need to find a program that logs them..

 

these options are grayed out on my 6935g, i cant untick the box.

any help?

will contact acer support later about this issue, i hope all aspire blue users will too.

 

they are greyed out on mine too...
i already contacted acer for this....hope ill get a response soon

btw tehsuigi ,as i understood,u got rid of u're throttling by undervolting ure cpu?
if yes,did u use this guide ?

 

No clue about the greyed out settings. Try using the RMClock_Wipeout.reg file first with RMClock closed. It's possible that RMClock hasn't been updated to the point where it can interface with the PM45 chipset.

Vlad6, I did indeed use that guide. It's not completely gone, but only one 60-second throttling incident in 3 hours of full stress testing is damn close.

 

I seem to have managed to finally get rid of my throttling issue. Stress tested with Orthos for a full 6 hours at 1.025v for my T5750 and no throttle in games, too. I solved the shutdown problem (100 degrees on the GPU!??) by simply removing the stupid perforated thing under the fan like said in some post here and my GPU won't now go above 83 degrees, while the CPU is at a maximum temp of 58. Thanks for the guide(s).

Now a question, sorry if it is a bit off-topic, but i'm thinking of upgrading the CPU to a T9500, is there a chance i'll have the same throttling issues with that one too?

 

Possible - I went from a T5550 to the T8300 I've got now (basically the same upgrade you're planning, just a few MHz slower), and both throttled for me. Then again, undervolting seemed to fix it, and removing the mesh probably helps a ton.

 

another problem.

rmclock temp reading on my P8600 cpu is stucked at 48C, hardware monitor on the other hand shows it is stucked at 43c.

im on bios 1.10, will upgrade to 1.13 later.

 

Erm it is very common? Did you mean the max temperature of your CPU shown in RMClock is 48C but HWMonitor shows 43C?
If you mean this, it is very common since HWMonitor and RMClock do not read them correctly.
Download Real Temp 3.0, it is better(basically true reading) on reading temperature of your GPU and CPU.
My Throttle FIX Gemstone Blue topic have a little tweak on RMClock to make it show correct temperature.

 

yep, and it never changes. tried playing crysis on windowed mode until my laptop throttles and the temp readings didnt changed at all.

will try realtemp 3.0.

thanks!

 

Another wild guess is that maybe the max temperature for it is 48C or 43C, perhaps. LOL.
Mine maximum would get about 53-55C. It won't increase any further too.

 

upgrading to bios 1.13 didnt help at all

 

Of course, because it is not the BIOS fault. It is the monitoring tools not able to read your CPU temperature correctly.
So, have you tried Real Temp 3.0?
For extra information, it is normal for a CPU to stay at its max temperature for a long period.
Well, have you tried tehsuigi's throttle fixing tweaks?
If you have tried it and the problems still there, you can try my tweak, here, http://forum.notebookreview.com/showthread.php?t=393073
If have any problem or question, ask me there. Thanks.

 

yep. real temp and rightmark shows the same core temp.

i cant try tehsuigi's fix coz some of the options are grayed out. i also tried your registry tweaks but havent tried undervolting yet.

 

You need a UNDERVOLT, if not, everything won't work. Same to Tehsuigi's method. It needs UNDERVOLT.

 

DarkSilver, I think the problem is that his temperature readings are STUCK, not that they're at their maximum all the time.
I wouldn't know how to fix that - if it's a temperature sensor problem, you need to be calling Acer Support.

(and HWMonitor does read CPU temperatures 5 degrees below actual on Acer models)

 

LOL. That would be awful. T.T

 

"Of course, because it is not the BIOS fault".

DarkSilver in a few posts above. Thanks for warning people DarkSilver.

Do not encourage BIOS upgrades other people....it's the very last thing to try when all else has failed.....

 

When did you see/read I told him to have the BIOS upgrade?
I did say "it is not the BIOS fault" means obviously "that it is not BIOS fault". Did that sentence mean "update your BIOS please"?
And for the other replies on few posts above, I did not told him to update/flash the BIOS. If you can't see or read them clearly, then, I would copy each of them out and show you. Seriously, do not simply say something that does not exist. I am not in a good mood now.
Lastly, I know very well on bad BIOS flashing result, it can lead to motherboard failure or system unstable/error/corrupted.

 

I edited to make my post clearer about 1 second before yours got posted.......

I agree with you dude. Chill

Now leave the mood and don't be so sensitive

 

I will be sensitive if something shoot on me LOL.
Anyway, you have edited your post. I should forgive you and I need to say sorry too for my CRAZY emotion.

 

wow...how did u disable it?

 

As I stated, 6930Gs are less prone to the throttling issue than other 69xx models.

 

In detail you can said majority of 6920G and 8920G has basically affected by throttle issues.
I know many 69XX/89XX users(not every users are interested on computer tweaking or exploring) did not know what actually happen to their laptops. If they know, I guess they would have complaint to Acer.

 

now trying at 0.9875v

looks stable. will update you guys later.

-edit-

nobody told me to update the bios. just tried it coz im having a temp reading problem. tought updating the bios will fix it.

 

do you guys have ACPI temp reading on Hardware monitor? I notice that if one of these ACPI temps reach 70c it throttles while the core temp is not changing at all!

 

I do, but I've never noticed if any of the thermal zones triggers the throttling.
And like I said, you need to contact Acer and tell them that the thermal sensor on your CPU is broken. That's the only logical explanation I can think of for why your temperature is stuck that way.

 

tried undervolting to 0.9875v and no throttling occurs while playing crysis for about an hour. i think its gone!!!!

 

Why are you complaining to Acer about broken CPU sensors?
Shouldn't it be Intel?
And no one tried by DSDT although they requested the mod...people...wasted my time...

 

Intel's not the one that's going to be able to provide a replacement under warranty.

I think the people are wary of trying the DSDT table because we've found that undervolting is sufficient in most cases.
Did you test it on your machine?

 

My Laptop doesn't have Throttling issues
The DSDT is for the Acer Aspire 6920G.

 

You're not wasting your time.
LOL.
The DSDT table was too advance, that's why people would seldom try it. They would basically stick with tehsuigi's tweak to my tweak(if tehsuigi's tweak fail) and then only go to yours(rare since it is too hard).
Anyway, you're contributing a lot of information. No worries. Your tweak would be use one day.

 

Hey guys, I just tested weinter's modified DSDT but the throttle issue still occurs.

I turned off all the undervolts in RMClock and just as it hit 70C on HWMonitor the throttling still kicked in.

I think some more people need to try this out as I could be doing it wrong. I do know that I applied the modified DSDT correctly.

 

Its on the "Mobile" setting already & the Notebook I'm working on is a "6930" not "6930G" (I guess the "G" stands for Gemstone)

In RMCLock -> Advanced CPU Settings -> Processor Tab -> Intel Core/Core2 Family Enhanced low power states -> Uncheck Enable Enh. Deeper Sleep (C4E) & Enable Hard C4E

True! I suspect this issue affects more Laptops too!

 

No, G stands for Gaming. All G models have a dedicated Nvidia or ATi graphics card.
Any recent Acer Aspire model that isn't an Aspire One is considered a Gemstone (16:10 aspect ratio) or Gemstone Blue (16:9 aspect ratio).

 

I always suspected I have this problem. Im on a 8930g and just caught this thread. I ran rmclock and ran a game mercenaries 2. After a while it became very choppy. In the rmclock monitor it shows core 1995 and throttle is going to 900's, so it is definitely throttling for me. I usually run elevated and that seems to fix the problem, but one game like flatout 2 still slowed down to throttling i recall. Im going to try the undervolt see what happens...

 

If you are confident about undervolting you can attempt to undervolt GPU as well.
Use NVFLASH on a bootable thumbdrive to flash the VGA BIOS and Nibitor to edit the BIOS.

 

could a laptop cooler solve the issue?

 

Yep! With undervolt(minus 0.1V at least) and cooler(good one prehaps), this THROTTLE problem would vanish. However, there is still a little chance that it won't help you solve this THROTTLE issue.

 

can it work without the undervolt?

 

I guess NO. However, you can give it a try.
OOO yeah! Environment temperature play an important role too.
Cooler environment can decrease the temperature of CPU, so, it won't hit the TM 1(which trigger throttle to start).
I tried went into a 16-18C room and play Left 4 Dead without undervolt. It didn't throttle at all.

If you're in a cool area with a cooler pad, I guess you can run away from throttle. However, in a hotter area, cooler doesn't help much. Yet, you can try.

 

that's why i haven't noticed throttling in a couple of months, it's because it was winter/spring, and now it's a really hot summer.

 

You're quite lucky that your country/continent have winter/spring/summer/blah blah. So, in mathematic calculation, your AS 6920G only would throttle 25% in a year. LOL.

 

yeah, so i assume your in a summer only country ?

 

Urmmmm. Not really summer. Is near-to-summer country. LOL. Quite hot if not raining or not cloudy.

 

is this totally safe?

also, what's the duration of this method? so when i exit the game, it's back to default?
