The Definitive Guide to Acer Aspire Gemstone Blue Throttling Issues

He did? Whoa, I had no idea.
Also: happy 600th post, throttlers.

 

oh Im very sorry about that I misunderstand throttlestop, LoL!

 

here's the new log file

http://www.sendspace.com/file/bn69qx

 

Vinch the new log file looks good. No signs of any Chipset Clock Modulation and the multiplier is mostly at 9.0 which is a good thing so your laptop is finally running at full speed and not being throttled to death.

When you post a log file, it's a lot easier for me to understand what's going on if you provide a few details like:

10:13:45 - Started hunting down bad guys.
10:52:45 - All finished gaming.

Your log file shows a minimum multiplier of 3.00 so that means that Super Low Frequency Mode (SLFM) is enabled and working properly.

The highest multiplier I noticed was 9.31 which tells me your CPU supports Intel Dynamic Acceleration and can use a 9.50 multiplier when lightly loaded and only a single core is in the active state. If you ran a single threaded benchmark like Super PI, you should see a lot more readings above 9.00 in the log file. Everything looks good.

 

unclewebb, that log file is a full game of NBA 2k10 (3mins/quarter). NBA 2k10 is one of my problematic games that triggers throttle even using the rmclock tweak and using a laptop cooler. I cant even pass 3rd Q before using throttlestop. Now that I have throttlestop, I can play the game flawlessly w/o rmclock and a laptop cooler (my laptop becomes very very hot when playing this game).

since I installed throttlestop, I never had experience throttling again. I dont even use my laptop cooler now.

 

That's great news Vinch. Thanks for explaining what you were up to during that log file.

Most 45nm Intel mobile CPUs are rated not to throttle until 105C. When this starts to happen the multiplier will rapidly cycle back and forth between 9 and 6 to control heat output. With the multiplier steady at 9 in your log file, that's a sign that your CPU is not throttling which means it is running within its thermal specification. It might be a little hotter now but as long as it is within spec and running at full speed then no worries. Happy gaming.

Edit: The thermal shut down temperature isn't until 125C. Some users get worried that if it hits 100C it will instantly shut down but that's not the way Intel designs their CPUs. They leave lots of head room in these chips so you can fully use them and run them at full speed.

 

Dudes... You seem to be the real experts in this subject.

I'm going to be honest, this is a big thread so I didnt read all of it. But I really urge for your help.

I have a acer aspire 6920g gemstone blue. The CPU is a intel core 2 duo T7500 2.20GHz. The video is a NVIDIA GeForce 9500M GS. Im running a Vista Ultimate 32.

I have experienced really bad problems with it. It feels to me the when i bought it, the gaming performance was a little bit better. But today after serverals formats it's really bad.

I cant play games like Borderlands or even Company of Heroes in medium. Prototype for instance, started really good, but after 3 minutes it became unplayable.

So now I search a solution. Im using ThrottleStop to check if there is Throttle and speedfan and coretemp to check teh temp.

I tried played the games, but ThrottleStop dont acusse Throttling. The temprature in the cpu is aways around 18 to 28 C never higher than that. So I'm confused.

What I want to know if is there something I can do?

And also, in a previous OS installation, i tried undervolting but got nothing but blue screen. Could it be that something a made then persisted in my BIOS until today, hence stoping me from getting a good performance?

Please help.

 

Hi leonardo, and welcome to the forums!
I've moved your post from the older throttling topic to the stickied one so people will notice.

Any number of things could be happening here.
1. The CPU is throttling, but for some reason ThrottleStop isn't picking up on it. Try enabling the Chipset Clock Mod at 100% anyway to see if that fixes it.
2. The throttling you're experiencing is legitimate, and from either the CPU and GPU. This could be:
a. because the fan can't draw air in - check the intake and exhaust for dust and clean it out.
b. because the thermal sensor on the CPU is broken (18-28 ain't right).
c. some other issue that we don't know right now

I wouldn't say that undervolting caused something to persist in your BIOS, specifically because undervolting with RMClock is a software-level change, not BIOS-level. The worst thing that can happen is that your system becomes unstable and BSODs - as long as RMClock doesn't start again, the system would be back to its regular voltages.

 

No throttling problems for me?

Hello to all. I have acer 6935g with p8400 and 9600m gt and have never noticed throttling when playing games. Anyway back to the point, I read almost complete thread here and noticed that Angelwings mentions two different types of bios v1.14 and that later has no problems with cinedash. If she or anyone else can point me to where to download this new bios please post reply here. Thanks forward.

 

@lunar: That's because this issue only occurs in certain Aspire models: 6920G, 6930G, 6935G, 8920G, and 8930G.

@jmhdj: I've messaged Angelwings to visit the thread and post information.

 

thanks for reply tehSuigi. I should do that anyway now . Have checked on google but there is nothing about new 1.14 bios. That leads me to think its unnoficial relase or what?

 

leonardojg: If you want ThrottleStop to display your core temperature on each core then add this to the ThrottleStop.ini configuration file:

TJMax=100

By default ThrottleStop shows you the data coming from the digital thermal sensors (DTS) and shows you how far you are away from the throttling point.

It would be a lot easier to help you if you posted a screen shot or better yet did some gaming and created a ThrottleStop.txt log file while you are gaming. Upload it to www.sendspace.com and then post a link to it here so I can have a look.

There are lots of people willing to help but we need to see what your computer is doing and how it is set up. A check mark in the Chipset Clock Modulation option in ThrottleStop is usually enough to fix up many Acer laptops.

 

Hi, my friend has an Acer 6935 and she downloaded the 1.14 bios from here...

http://forums.mydigitallife.info/th...for-Acer-Aspire-6935G-8930G-Slic-2-1?p=228110

She had no problems with her cinedash, Im sure I download mine (8930) from a link somewhere on this forum but that link should be ok. as its the Official Acer Link.

 

Thanks for answering Angelwings. Unfortunately I Have tried that bios yesterday and it made my cinedash dead . So if thats the one then Im out of luck. Also when I extracted bios folder that contain it is marked as acer 8930 bios on both files.? One more thing is there anyone with 6935g that can monitor their cpu temp constantly, I mean not just static temp reading which shows actual temp of startup. Thnks

 

When running 3DMark06, your CPU should be using its full 16 multiplier. It looks to me like it is throttling all over the place during that test with the multiplier dropping down into the 12 or 13 range. That's not right.

When testing keep track of exactly what you're doing so you can go back and add a note or two into the log file at the appropriate time to make it easier to follow.

Your Orthos test is only working half your CPU. Download Prime95 so you can fully load your CPU with as many threads as necessary. The Intel specs say an i3-330M is a Dual Core that supports hyper threading so you need to run 4 threads of Prime95 to fully load your CPU.

http://www.mersenne.org/freesoft/

When you have 4 threads of Prime95 Small FFTs running, try running Furmark at the same time. You will likely see some throttling then. Prime95 alone might be enough for throttling to start.

unclewebb, thx for the help

i will create the log and will post it as you required

 

This *appears* to be great work. Unfortunately, I must be full of fail today since I can't even seem to find its home to download it. I've spent over an hour reading through this thread (obviously not all of it, but good stuff) and now a half hour setting up a fileden.com account, dealing with 20 pages of adds and futzing around with it.

I've tried various links throughout the thread with no luck. I've tried the initial link to download ThrottleStop (on first post) on 2 computers and 3 browsers now (Win7x64 and Linux) and either that link is dead or fileden is the biggest scam site out there (which it seems to be anyway - not sure why anyone would use it ESPECIALLY with the forced phone number and address, which it does check area code+prefix, zips and validity of city names :-/). Sorry, no offense, I'm just thoroughly frustrated primarily with fileden and a not-so-old thread filled with many dead links.

Does ThrottleStop have a new (or better) home that doesn't require my name, address, ssn and first born + 20 scam adds for online degrees and credit card applications?

Thanks much.

Signed,
I used to know how to use a puter

 

Argh, goshdarnit. My apologies, hexbear.
I somehow botched BOTH links in the first post - they were missing a digit.
Try it now, or just click here.

 

There is NO way - too many of your posts are great... this would have never occurred to me!

As long as you didn't send me a package of malware for venting, I got the file and thank you tons.

Now, off to see what I can do.

 

Now why would I go and do a thing like that?

 

Hi, so i have a Acer aspire 6935G. Now, i had that throttlingproblem, which luckily throttlestop fixed. Now, my problem is that my computer just shuts down after a while of playing. Any of you have any idea of why ? Is it some settings in throttlestop i could change in order to prevent the computer from shutting down ?

 

Quakecry: I put an answer for you in the other thread you posted in. Your CPU is too damn hot. You might want to find another thread about how to under volt your CPU to get the core temperatures down.

I've never had a problem with FileDen for hosting files. You don't need to be a member there or give them your phone number or next of kin. Hopefully the updated link works now.

 

waves at unclewebb, just installed realtemp on my new acer notebook

 

Hello eva2000. You've got as many accounts on different forums as I do.

The Load meter in RealTemp is a little funny with Core 2 CPUs that go into the deeper sleep states. It is based on C0% and at idle, it tends to increase which is a sign of how well your CPU is able to stay asleep. There is an option in the Settings window called TM Load that lets you see a number similar to the task manager load meter.

I'll have to check the VID formula that RealTemp is using. If you look at the CPU-Z specifications box, that shows what information is written into the chip. Intel uses U3500 but software is supposed to figure out that they really mean SU3500. I'll make sure that works correctly in the next version.

It's getting the TJMax correct at 100C so your temperatures should be as accurate as these sensors are capable of.

First off, big thanks to Unclewebb! I've been putting up with throttling for atleast a year or more on my lappy, and this seems to make gameplay 'almost' perfect.

I'm using an acer aspire 8920g, or so I think atleast. The sticker pasted on it seems to be slightly wrong. As it says t5750 proccessor at 2ghz. Whereas system settings shows t7500 2.2ghz. It also has 3 gb memory and the geforce 9500m Gs. So I'm curious if it's a 6920g maybe?

Also, i'm wondering if after you lock the multiplier in throttlestop at say 11, if it's supposed to keep changing, say for example from various numbers between 6-8?

Because ingame, I get solid fps now, but it seems to hit random 1-2second patches where it will lose 1/3rd of the fps rate for a moment. Then return to normal, almost like it's attempting to throttle then instantly pushed back up. In shooters this seems anoying as you freeze multiple times a game and die, or walk off a cliff.

 

The first digit of the model number refers to the screen size - 6 being a 16" and 8 being an 18.4" screen.

 

Your multiplier at idle will depend on how your power options are set up. In Vista or Windows 7 set the Minimum processor state to 100% and see if that helps. Also disable C1E. When C1E is enabled you can get the multiplier at idle bouncing around randomly. You can use RealTemp to adjust C1E or you might be able to disable it in the bios.

Unfortunately, only Acer can make these laptops perfect. All ThrottleStop can do is react to throttling after the fact. If you can, post a ThrottleStop log file while you are gaming. Check the Log File and More Data options in ThrottleStop. Upload the log file to www.sendspace.com or similar and post a link here.

Some people hit slow downs in gaming because their graphics card simply isn't powerful enough and think that it is CPU throttling when it really isn't. When I see a log file then I can learn some more about how Acer handles throttling. Each manufacturer does things a little differently. The more I learn, the more I can improve ThrottleStop for users.

 

In poweroptions I have it set to 100% cpu in every setting I could find. Havn't really been able to change 'anything' in the 1.14 bios I got from acer, well besides device boot order. Though, today I tried locking the clock / chip clock mod in Throttlestop, well locking the multiplier and voltage in RMclock and it seems to be working perfectly.

Atleast in the logs from rmclock it ran smoothly over the course of an hour and a half. And ingame you no longer see any fps hiccups. So we'll see how this goes, or if it was just a fluke miracle test.

Any problems with using Throttlestop and RmClock side by side? I remember you saying something in a few of the posts about conflicting with each other?

 

For the multiplier and voltage I would use RMClock or ThrottleStop but not both since the two programs will fight over the same registers. If you are using RMClock to manage multipliers and voltage then there's no problem using ThrottleStop to control Chipset Clock Modulation since that is the issue with Acer laptops. I don't believe any of them are using regular Clock Modulation so whether you have that checked or not in ThrottleStop shouldn't matter. I'd leave it unchecked if the log files show a column of 100% and shows that it is not needed.

Edit: A T7500 supports Intel Dynamic Acceleration which means when lightly loaded it can use a multiplier as high as 12.0. I'm not sure if RMClock will allow you full access to this.

Run a benchmark like Super PI and post a screen shot of ThrottleStop about half way through this calculation. I've seen average multipliers as high as 11.9 during this sort of testing. I don't think RMClock can accurately report this and it might even block IDA from being used if not set up correctly.

Here's how a T7300 looks. A lot of software including CPU-Z can't report IDA correctly.

 

hello

i know u guys asked me to make some tests but i've been very busy
so... i've noticed my acer actually is faster in balanced mode tha high performance mode. in hp its start's freezing.

Any ideas?

 

Wow, this is great! Just found this thread after randomly checking the Acer board - I've had the 8920g for about 2 years now and never understood why I get the slowdowns. Big thanks!

 

Glad we could be of help, ugly_bear!

 

Hi Everyone and thanks for all the hard work on this problem.

I've had my 6935G for a year and never had throttling problems before even though I live in a hot climate. I keep the fans clean and I'd never noticed throttling. I used to game a lot - nowadays not so much as I have a baby daughter! However, 2 days ago I upgraded to V1.19 BIOS and now I'm seeing throttling for the first time.

Unfortunately I don't game often enough anymore to be able to say for sure that V1.19 caused the problem, but I can say that I never noticed it until 2 days after that BIOS.

**Even worse** - Throttlestop doesn't seem to fix the problem for me - if anything it makes it worse - the game speeds up/slows down/locks up for seconds when Throttlestop is running. Without it, the game just slows down in a more predictable way.

Can anyone else confirm if V1.19 and Throttlestop are compatible/incompatible? I might try to roll back to V1.13 and check it myself if I can find some time in the next few days...

 

^make sure you tick the "chipset clock mod" in throttlestop.

 

Hi, thanks for the reply - but I did tick it already - the second checkbox down.

 

thank you!

my son bought himself the quad core 8930g last August. he only plays World of Warcraft but normally within 20 minutes of playing his frame rate would drop to around 9fps making the game unplayable for him.

weve tried running WoW with everything set low or turned off, same problem. weve updated graphics drivers, got our free Windows7 upgrade and installed that, checked cpu and gpu temperatures and nothing has worked or pointed at a problem.

the first time i ran Throttlestop the numbers in the red box had dropped to 25% when he got the frame rate drop. hopefully this is going to work, ive had enough of a 17 year old stressing when he dies during a raid because his fps has dropped!

one other question though, cpu and gpu temperatures, what is too high for them??? cpu temp is normally about 45 and doesnt fluctuate much at all when playing WoW, the maximum gpu temp we have seen has been 65. is this ok?

 

Hi Jeni, and welcome to the forums!
If the Chip% numbers drop below 100%, that's a definite sign of chipset throttling.
Tick the Chipset Clock Mod box before playing and you should be fine.

Temps look fine - start worrying when your CPU and GPU get into the mid-80s.

 

At what temperature would you say that a 8930G with a Q9000 processor is right to start making throttle?

Mine starts at 70 º C.

Thanks in advance.

 

Normal CPUs should start throttling in the mid-90s at the earliest - anything lower is a symptom of wayward chipset throttling, which ThrottleStop is designed to prevent.

 

Intel lists the thermal throttling point for a Q9000 as 100C.

Intel® Core?2 Quad Mobile Processor Q9000 - SLGEJ

I find that Intel Core 2 based CPUs usually start to throttle a degree or two before this limit to help keep the maximum temperature under the 100C limit.

 

I sent the laptop 5 times and fail to fix it. Acer has changed motherboard, processor, heatsink and the notebook and in all cases the same result.

In addition to the throttle in rare cases, the notebook is turned off.

Thanks for your help and the throttlestop.

 

I can't seem to fix the problem in throttlestop, when my pc starts to lag (in MW2) and I switch to throttlestop, the chip% is still at 100, but the C0% is around 50%. When I start playing, or do a benchmark, the C0% value starts at 100% and after a while it goes to 50% but my GHZ doesn't decrease from 2000 to 1000. And I can't check the Chipset Clock Mod box.

I hope someone can help me out. I hate it when my pc first plays MW2 so smooth and then after 5 minutes it starts to give me like 5fps...

Hi, I have an Acer Aspire 6920G, and I've download the program ThrottleStop, but after I open it the Chipset Clock Mod ins't avaliable to turn on. What is the problem?
Thanks.

 

I've got the same problem as the two above posters. The Chipset Clock Mod option is not available even though it worked in version 1.92

 

I disabled Chipset Clock Modulation a while ago because it was not operating properly on my Dell D830 laptop. I've been waiting and waiting and waiting to get some feedback to find out what laptops this works on and which ones it doesn't.

I will unlock this in the next version of ThrottleStop since it obviously works correctly on the Acer laptops without causing any issues. I'm not sure if the chipset Dell uses is a slightly different model or what?

On the Dell, when you manually adjust Chipset Clock Modulation, the adjustment goes directly to the regular clock modulation slider and display. It works correctly on other chipsets so I temporarily blocked it until I could find out some more. I'll enable it again and get an updated version uploaded shortly so you can test this out.

Edit: I just uploaded a fixed version with this feature unlocked.

http://www.fileden.com/files/2008/3/3/1794507/ThrottleStop.zip

To test this can you adjust Chipset Clock Modulation from 100.0% to 12.5% and make sure that this also adjusts the chipset clock modulation reported in the monitoring area. On my desktop it does but on my Dell laptop it doesn't. Hopefully this still works correctly on the Acers.

Here's an example of what happens on my Dell.



When I adjust Chipset clock modulation, that command is going directly to the regular clock modulation. This happens on my laptop with the Intel PM965 chipset but it works correctly on my desktop with a similar 965 chipset. No idea why. If it works again for Acer then let me know. If you can, post the Mainboard tab of CPU-Z to help me out. Thanks.

 

Thanks for your help, I've download the new version, activated the Chipset Clock Mod, and my game dind't throttle (I'm going to try with other games.)
It should be set to 100% right?
And should I activate the program only if my system throttle or before go to play games?
And here is the printscreen you asked:
Thanks.

 

I downloaded the fixed version but it didn't fix the problem for me. Here are some pics :

 

If you are using Firefox, try clearing out your cache and then try downloading it again. If you right click on ThrottleStop there is an About box that will show you the version. It looks like the old version and not the one I just uploaded.

andre159oliveira: You can leave ThrottleStop on all the time if you want. Just leave Chipset Clock Mod always set to 100.0% and have it checked. You might want to also check the Set Multiplier option and try lowering your VID voltage a little. Most laptops can run reliably with a little less voltage and they will run cooler too. Use a stress testing program like Prime95 with the Small FFTs option. When testing, lower the voltage in small steps and make sure your computer is stable at the new setting. If you get errors in Prime95 or your computer freezes up then you have reduced the voltage too much. If you have to, re-start your computer and try again with a little more voltage. Only use as much voltage as your CPU needs to run 100% stable.

Can you post a screen shot with Chipset Clock Modulation set to 75.0%. I would like to see if it works differently on Acer laptops compared to my Dell. It seems to work differently.

I also uploaded ThrottleStop to SendSpace in case you are still having trouble with the other link:
http://www.sendspace.com/file/posq5w

 

Yeah it seems like I downloaded the same old version again. I used the sendspace link, and now I've got the new version. It now works, so thank you again unclewebb for all your great work
