The Definitive Guide to Acer Aspire Gemstone Blue Throttling Issues

YES! Once you exit the game, it's back to default. That's why this tweak is so-called SEMI-FIX. Due to it can't totally fix the throttle problem or it can only fix the throttle problem on some machines, not all machines.
Duration = before you exit the game.

As for the COOLER PAD again. I forgot to tell that DIY type of cooler pad = better than a market cooler pad.
A superb powerful fan which you attached/adjusted it nicely on a metal plate(while holes) or metal cage. Make sure the Fan you attached is blowing the CPU part.

 

As far as the market cooler pad is concerned I can add here that I have been using one (good quality too, with 2 powerful fans) and I didn't see any difference whatsoever, even being in a cold country like UK compared to where I normally live in Greece. What completely solved the problem for me seemed to be the combination of undervolting and the removal of ALL the meshes (especially the GPU and FAN ones) under the hood. Those 2 had accumulated that much dust I couldn't see through them anymore. It is really the most stupid thing i have ever seen in a laptop design, while it can keep the dust away from the mainboard it seriously undermines the cooling capacity in a laptop that uses one fan and an exhaust connected to both the CPU and GPU.

ACPI on the other hand does seem to trigger the CPU throttle, and it actually makes sense, because in gaming conditions without undervolting the CPU can go up to 68 in my T5750 and the GPU all the way up to 85-90. It looks like the thermal zones start from 53 for the first fan speedup, 58-60 for the second speedup and 70 brings the throttle on...

 

Different than my system - the GPU's temperature seems to trigger the fan, not the CPU. So as a result, I throttle before 60 degrees.

 

same here (i have the same cpu).

also, has anyone tried if throttling occurs with epower installed and configured at high performance? cause i have had it uninstalled since day 1. maybe it overrides throttling??

i really hope they can fix it using a bios patch. for now, i can live with the semi fix provided. i've emailed acer, they still didnt reply.

 

Now, I am having a headache on my GPU.
It turns back to his stupidity random downclock =.=!
I gonna fix that, damn!! I don't know what have happened.
PowerMizer already turned off. I checked it a few times. Still, random downclock =.=!

Meanwhile, CPU doesn't throttle. ARGH STUPID GPU!

@hna,
Acer seldom reply the mail, instead they call you via phone.

 

Why don't you give the modded DSDT a spin.
I dare say it should work.

 

Hna, I tried using ePower once when I had done a factory reinstall (just to check). Still throttled.
And yes, Acer's email response time stinks. Give 'em a call instead.

 

Hey! I just notice the SUPERFETCH may affect the CPU and GPU temperature.
With SUPERFETCH enabled, the HDD activity is increased too. Thus, HDD is heated up more than usual. Heat = Not stay a point or rigid. Heat = Area of Effect.
So, HDD heated up, the nearby stuffs would increase temperature as well.
This theory was very logic and make sense:
Turn on the natural gas cooker(fire) in the kitchen, put a metal stuff near to the fire. After a few minutes, check the temperature of the metal stuff. It is heated up right!?

However, disabling SUPERFETCH, the system performance would reduced. T.T

 

disabling superfetch wouldn't reduce performance. i have it disabled whenever i reinstall windows.. it just shaves a couple of seconds of a frequently used application boot time. i personalyl think it's unneccasry.. here's acer reply to my email:

?

 

Not necessarily and i think i can prove that:
As you probably know, the Txxx series (Core 2 Duo) have two thermal zones (TM1 and TM2) along the temp sensors inside the chip itself (thus two different temps on each core). Your GPU, again, has an embedded temp sensor, too (either nVidia or ATi, they both do have one). If you take a close look at the four acer sensors you'll notice that they go along the temperatures of some components in your system. In my case I found with the help of Everest that two of them are called "CPU" and "Motherboard". CPU is for example right now at 44, MB at 42, while my two cores report 22 and 26. The GPU is more close at 48. Now, both of these two (CPU and GPU) can trigger the fan (since it is shared) and its done through ACPI, or one of the two acer sensors (in my case i found it to be the CPU one). CPU does not necessarily mean that the sensor is directly on the cpu, or that there is a sensor, rather than just an estimate of both in the ACPI (although that would be plain stupid). Moreover, there is no fan control in my ATi bios either (and I bet there is none in the nVidia too).

Do you throttle when running just Orthos and nothing GPU intensive? Have you tried unchecking the "Enable Extended Throttling" in RMClock (and leaving it this way)? Also, try unchecking all the low power states too, while it didn't matter in Vista, i found that unchecking them along with all the other settings removed the throttling in Win 7 x64 (i see in your signature that you have them too).

Just tested your DSDT table, and it didn't report 10 degrees lower, still throttling without undervolting

 

Thanoulas, nice research! Didn't think to use Everest.
My system has throttled in Orthos AND in CPU-intensive 3D games such as Team Fortress 2 (and even in Audiosurf, back when this issue was just coming to light a year ago).
Unchecking Enabled extended throttling and ditching the CxE states still had throttling woes when I was back on Vista, but since I've undervolted so much on 7, it's a non-issue for me.

 

Send him plenty of our topic regarding this stupid problems at point out it is not the software problems.
Those people think we're newbie and they don't know what exactly happen.
So, they would answer/reply some useless craps.
That's why sometime I feel lazy calling them. Making them to understand is like forever.

Everest of course, it is great. I have it too. XD!
However, it needs to pay =.=!
My tweak actually develop from observing those stuffs in Everest Ultimate Edition. I found Tjmax, TM 1, TM 2, EIST kind of stuffs. I saw these settings in RMClock too. I begin to think and tinkering with the RMClock Registries. I successfully create the solution. However, now, I am on stupid Nvidia GPU(overclocked) downclocking issue again(basically on The Sims 3 only)!!! I have disable the PowerMizer!! Still!! Anyone have any idea???

 

yep, i believe its the thermal zones too. when it reach 70c for several minutes my laptop throttles.

 

Did you all mean the ACPI zones?

 

Just to be sure did you install it correctly?
You have to get the table overload message successful to be sure.

Ok to conclude is it the GPU that causes the throttling or the CPU?
If it is GPU then you can try using Nibitor to modify the GPU slowdown temps

 

Perhaps a stupid braincrackling I had. But why do we all rely on rmclock? That program is no longer supported. Some users here report the advanced chipset tab being grayed-out (as do I, 8930 with a x9100).

Isn't a program like crystal cpuid a better solution? Sure it has a different look, but it can do pretty much the same. I think I go look in that direction as I have a found something like advance multiplier settings and you can lock you multiplier. (isn't that what throttle does? switch to a lower multiplier a.k.a intel speedstep)

I need to restore my lappy to factory defaults and then I think I will thinker with crystal cpuid. At least all the functions are available.

PS. Rmclock doesn't even see my chipset :S

 

Throttling isn't switching to a lower multiplier, it's activating the On-Demand Clock Modulation (ODCP) of the Core 2 Duo and forcing the CPU to perform slower on the same multiplier.
But please, go right ahead and try CrystalCPUID. Maybe it'll help!

 

edit: wrong thread lol

 

I was wondering if the Chipset and Throttling options in RMClock being greyed out is due to old chipset drivers? I personally haven't encountered this issue.

 

It is not greyed out due to old chipset/drivers.
Basically, it is due to:
a.) BIOS setting(which Acer has locked many of them)
b.) Wrong RMclock registry setting
c.) The CPU is too new, RMClock(already stop develop long ago) does not have the information of the CPU

 

What are the latest CPU's/Chipsets that RMCLock support's?

 

It said Penryn Core if not mistaken. Go to RMClock official website for details. Thanks. The website is here, http://cpu.rightmark.org/products/rmclock.shtml

 

Thanks ... I was looking for information in terms of the Chipsets/features supported (esp. Centrino 2)

 

nope. only 2 for me. my P8600 have 4 thermal zones. TZ00, TZVR, TZVL and TZ01. Only TZVR and TZVL reach 70c.

 

i'm using the semi-fix of rmclock, and it's working great! Finally, I'm able to play with no fps drops whatsoever!

 

acer sucks!

 

Unfortunately I think you may be experiencing more throttling than others because you upgraded your CPU, which runs a bit hotter (plus there is a +5 degrees limit of 105 instead of 100 on my T5750). Try my suggestion in 7 though it seems that windows manages the CPU in a different way than vista, it is evident even in the RMClock monitor. Plus, you have to try that undervolted

Yeap weinter, i got the message and windows requested a reboot, i am pretty sure I did it the right way and i used the latest DSDT table you posted. Idle temperatures are all exactly the same... Maybe we have to put it in a customised BIOS? (yikes!)

No it is not the GPU, it is the combined temperature that the system reads from a specific sensor of both the CPU and GPU temps, which is either malfunctioning or poorly calibrated in the BIOS. GPU is not slowing down at all, mine got up to 100 before shutting down the system, and it was because of accumulated dust on the mesh under the fan. Cleaning that up, and it gets to 83 tops even in very graphics intensive games.

 

I think I may have found the cause after investigating more thoroughly
Problem comes from _CRTT (Critical Temperature) which traps at (0x47 hex) 71 degrees I modified the values to (0x63 hex) 99.
Can you try the new DSDT?
If you want other values feel free to tell me as I don't know the number you require.
And also Acer actually did a poorly done DSDT as I encounter lots of error using Intel ASL therefore I had to use Microsoft ASL

 

This one critical at 80 degrees (if I remember correctly it is the Intel Processor limit)
Rename to DSDT.AML as with the previous post and overload it.
It is already aml compiled.

 

It seems the throttle seems to strike back to me if I do not use 0.925V. Currently 0.925V give me strange FID(jumping like ). ARGH!!! Don't know the reason!!! Try bunch of stuffs still can't. DAMN!!
I am planning on installing Windows 7 RC as Tehsuigi mentioned, the throttle issues on Windows 7 RC can be delayed or disabled. I hope it does help.

EDIT: It seems is the EIST problem which it can't be disable due to Acer BIOS Locked. When I running games and so on, the FID seems to be stable again. I think this is not a big problem. Yet, I will try 64bit OS soon. XD

 

Good job weinter, unfortunately I won't be able to test this one out yet because I am currently on vacation without my acer. As far as the absolute limit Intel has on the T5750 processor this is at 100 degrees and for later processors it is 105 you can check them out here on this link

I can certainly say that there is a huge difference as far as performance is concerned, though the throttling issues do seem to be delayed due to the x64 instruction set (which is the core 2 duo native) and there are lower loads from the OS (Win 7). Try it and you won't miss, i'm certainly not going back to Vista...

 

I have x64 and x86 Windows Vista only.
The Windows 7 x64 is RC version.
If I have extra pocket money, then, I think I would buy Windows 7 Ultimate x64. If I don't have golds, then, I think I would stick with my Windows Vista x64/x86 or wait my friend to get the pirated version of Windows 7.

As for the Processors Tjmax(maximum temperature supported), C2D T-series would basically have 100C to 105C.
My C2D T8100 have 105C as the Tjmax. Tjmax can be check using Real Temp 3.0 or Everest Ultimate Edition.

Back to topic,
Just now, I successfully make my RMClock stable again using 0.925VID. Phew~

 

Why don't you just use the semi-fix? it works just fine.

 

Me? Yea, I will use it(semi-fix) when it throttles. Well, I has been using semi-fix about half years. It is annoying to alt-tab and click click click, then, back to games again. After some research and experiments, I didn't suffer throttle anymore. This is due to my beloved Rmclock tweaks and my vacuum.
You can check my tweaks(throttle fix) here, http://forum.notebookreview.com/showthread.php?t=393073
If not mistaken, I thought I saw you before in my throttle fix tweaking topic.

However, I do agree with Tehsuigi, cleaning up the dust and lowered the VID can help to delay the throttle.
I do have my CPU running at 0.925V and I won't suffer the throttle using that VID even I run Orthos or Left 4 Dead for hours.

ARGH! SH!t~ the EIST strikes back!! DAMN!! Nevermind, as long as it doesn't throttle while gaming. LOL.
Recently found out that the FID would be unstable with 0.925V on my C2D T8100. This is due to too the programs during start-up has been decreased. =.=! I tried to increase the loads, it seems to be stable with more loads. Which mean while gaming, the CPU FID and VID is very very stable. =.=! So strange. LOL.

 

yeah, but isn't the semi-fix more stable and safer? i just wanna know.

 

YES! It is safer I think. LOL. You can even use the semi-fix without undervolt too. But 1 thing you should know is that lower the VID, the lower the temperature. Which mean if you have high VID and uses the semi-fix, it might be bad because the temperature may continue to increase endlessly after you apply the semi-fix. If you low VID and uses the semi-fix, it might be good because the temperature would increase slowly and won't increase anymore(reached certain peak).

 

I just came out with an idea but I am not sure it is will work because I don't know how to do it. It is mere an idea only.

Disable the temperature sensor of the CPU, it is possible?
I mean via the Device Manager, I saw a lot of ACPI blah blah stuffs there.

Hello, Thank you for contacting Acer.

Regarding your enquiry,

If it was are fault and a known issue then every single one of the 6920 models would have this issue which is not the case at all so im afraid if you want us to assess/repair the laptop it will be a chargeable process as it is out of the manufacturers warranty

Regards
Jonathan
Acer Technical Support Team

 

Send him this bloody thread and I think there is 1 thread about how many people with similar issues.
In addition, find some other topic regarding this problem around the internet(a lot of 6920G have throttle problem but they think is GPU overheat damn!) and send him see this is not our problem but it is Acer problem.

 

I'm thinking of buying this laptop
AS6920-6898
http://www.newegg.com/Product/Product.aspx?Item=N82E16834115571

Is this model prone to this "throttling issue?" Seems like most of this thread refers to a 6920 G model, what's the difference? I'm not a hard core gamer but enjoy some flight simulators do a lot of video editing.

Should I stay away from this laptop?? Or is the throttling issue minor enough that I should still purchase it??

 

The G stand for Gaming.
AS 6920G has a dedicated graphic card.
Well, if you're doing 3D video editing(animation), you need a graphic card for sure.

Yea! This model love throttle very much. Throttle is its life-time partner. LOL.

 

Well this one might not throttle as much as the G series because the Intel graphics card is not what you'd call "hot"

But if for flight simulations you mean Microsoft's, then you should probably stay away from it because there is no way you could possibly enjoy the game with Intel's card...

 

Did someone tried this DSDT???? It was the one he modified but no one tried. I'm not sure how to do this. We should not let this opportunity go to waste. If someone could inform me how to load this properly I am willing to try it. It just seems everyone forgot about this.

 

im unable to do anything under the throtling tab in Rmclock, everything is locked

 

Welcome to forum, buzk.
You mean you're using the "semi-fix"?
It is not necessary to use the throttling tab, you can use Processor or Chipset tab instead. Just click on the refresh, then click apply. The throttle will gone and you can enjoy your games.

 

^thx, ill try that later

 

Hya there people,

im new to this forums, came across this after searching for hours and hours on google trying to solve my Fps drops in games after 10 minutes of gaming old games like Bf2...since my 9700m Gt normally would eat games like Bf2 for breakfast i almost went insane

after trying couple of things and formatted too many times i tried the undervolting tweak with Rm..

now it seems alot more stable, but i noticed my Fps werent as high as without the undervolting...

My Vid is set to the lowest possible ( 0,9250v ) and with enough experience i would say a undervolt could not affect the processors performance as long as it runs stable at those voltage ratings right?

 

Came across this forum and did the tests on my 6935g notebook p8600/ gf9600 and it throttles
after 11-12mins of running ORTHOS. Though am not so much into gaming, knowing that my notebook
has this problem really bugs me. Been searching the net and found this
utility called CPugenie. (see link below)

http://www.clockmod.com/index.php?/articles/view/notebook_temparature/

It claims to lower cpu temperature by a significant amount by undervolting.
Is it similar to what is being done in this throttling forum?
Has anyone tried it (CPugenie)? could it be the solution to our throttling
problems with the gemstone blues? If I do under volt, Can i damage the
notebook cpu,gpu,MB or anything in it?

Also one thing I noticed is that the Bios for some of these models are the same
(6920G, 6930G, 6935G, 8920G, 8930G). Found it weird that the 8920 and 6835g had exactly the same BIOS file.
Therefore is it possible that this is a BIOS issue?
Hoping it is, so that a simple update by ACER would fix this problem.

 

Sorry but what is throttle and what does it do / harm?

I have an acer 8930G with Q9000 2ghz 1066fsb 6m cache, 9600 GT 1GB graphics, 1000GB hard drive, TV Tuner, 4 GB ram. Deciding if to use vista 64 bit or windows 7 64 bit.

I want my system to run the best way possible so basically can someone explain what I need to do to get the best out of it? Cheers

 

So if I were to buy a 6930G or 6935G a, I likely to experience issues with throttling and is it something that should put me off buying either of those?
