The Acer ThrottleStop Thread

The most important change is that starting with ThrottleStop 1.94, it won't expire anymore. The donation button hasn't been used much lately but I figure users have suffered long enough so ThrottleStop is freeware now. If you want to buy me a beer, that's OK too. You don't have to worry that I will hold a gun to your head trying to get $5 bucks out of you or forcing you to go to some pirate website to get a crack for ThrottleStop.

In the most recent version, there were a few minor changes to the VID formula mostly for Extreme mobile CPUs. There was also a change so it will work with older CPUs like the T2300 Yonah series. Other than that, same old stuff.

Happy gaming.

 

Hello there guys. Im wondering where I can get the newest updated ThrottleStop, cuz the version I got tells me that it has expired. I then press OK, and it downloads another one, but it's the same. Expired. Would be awesome if some of you could give me a link Thanks.

 

If you are using Firefox then clear your Cache. Instead of downloading a new version it is just getting the old version from your hard drive instead.

Version 1.94 is available from the fileden site.

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

In Firefox go to the menu item Tools -> Options -> Advanced -> Network and click on the Clear Now button. Then try downloading it.

 

I upgraded to 1.94, but my settings won't stick anymore like they would in the previous version. I have it running in my startup folder. Now every time I reboot my computer, it gives me the warning about using Throttlestop and I have to re-enter all the settings. Is there any reason in particular it's acting this way now? Is this something you changed in the latest version? Or something I'm doing wrong?

"Nevermind, I realized I need to exit the app entirely after dialing all the settings, then reopen it."

 

That might have been designed as a safety feature so in case someone made some adjustments to voltage, etc. and their computer locked up, those settings wouldn't be saved. Glad to hear you got it working.

 

Completed Bioshock 2, thanks throttlestop and of course kevin.
Time for my next game

 

Ok. I am a Lenovo user and I read the *whole* thread but as some of the undervoltaging terminology is unclear I have a few questions:

1. I will not auto start the program. I have a Lenovo T400 with a Intel T9900 CPU and no throttling issues. I will only use TrottleStop for undervoltaging to get more battery time. What exactly do I need to set on all these options for lowest possible watts used?

2. Can you explain (again?) how all the boxes with numbers are interconnected with each other - i.e. when i move one up what about the rest - do they have to go up or down?

3. Just to make sure again - undervolting can not damage anything, right? Only overvoltaging?

4. If uninstalling, is deleting the TS folder enough - nothing is registered in windows, added to registry, etc?

Also to add my vote for having the functionality to select the frequency and voltage based on cpu load. (no load = low MHz, low voltage mode; high demand = high freq, higher voltage). Or at least remember the combination voltage/frequency and have it change automatically when using one of the up/down buttons.

Finally, thanks for doing this for the "common" good. People appreciate it!

 

My worst experience when under volting a long long time ago was I went too low in one big step in the bios with voltage, booted up and got a BSOD which caused an error on the hard drive and then I was screwed and couldn't boot up anymore even after the voltage was reset in the bios to the correct amount. No modification is 100% safe. Anything can happen. If you use some common sense and slowly under volt a notch here and there and make sure you are Prime95 stable at each notch down then you probably won't run into the disaster that I once ran into when I was in a big hurry to under volt. Baby steps is the key.

ThrottleStop never adds anything to your registry so you can move the folder where you like and delete it when you are sick of it.

Most users that under volt are using RMClock. It is better integrated into the operating system and safer once you get it set up. The dilemma for me is that there is some interest in adding more RMClock like features to ThrottleStop but the newer Core i CPUs don't have adjustable voltage and most Core 2 owners already have a solution with RMClock so there isn't too much demand for me to re-invent the wheel.

A lot of users use ThrottleStop to max things out while gaming and then turn it off after that. I might add more features into it but there hasn't been a big demand for that so far

Show me a screen shot and ask a specific question about what box means what and I'll be able to give you a better answer. Read the included documentation too which might answer some of your questions. Do a search for an under volting thread. There is lots of good information in a thread like that about how to accomplish what you're looking for.

 

PERFECTT!!

working very good @Asus UL80VT



but i can't change voltage lower than 0.875V, for next release of throttlestop.. can i request lower voltage more than that?

 

Thanks for the detailed reply. I am now a bit more familiar with the link between voltage and frequency but that made me wonder how to find the default voltage for each supported frequency.

As TS does not automatically reset to the default (or previously manually set) voltage for a given frequency when the frequency is "upped", it is really easy to get you PC to freeze. I would imagine this to be relatively easy to implement in a future version.

I understand that RMClock provides some additional benefits but I much rather use a program that is simpler and focused on just a few things and does not leave traces behind once uninstalled (like RMClock). On my PC, RMClock does not integrate well maybe because of the 1/2 multipliers or because of Win7 x64, it got uninstalled quickly. Lenovo laptops come with a proprietary software that does power management better then RMClock or windows as it can use some specific features of lenovos (like optical drive power off, battery charge thresholds, managing the switchabe graphics, etc) so having TS overlap some of the features of RMClock can be good for some users. After all, RMClock is no longer developed.

 

kong ming: Each CPU has a unique minimum voltage that it can be set to. 0.875 is likely the minimum for your CPU so software can't make it go any lower than that. Happy to hear that ThrottleStop is useful for you. Try downloading the latest version of CPU-Z. It's better at reporting SLFM mode when it is being used.

garga: I plan to continue to develop ThrottleStop further but I don't have as much time to put into this project as I would like. CPUGenie is another tool that might be useful for you to try. I think it has a free 30 day trial period or something like that.

 

anybody tried running both rmclock and TS?

I configured RMClock for max performance and low voltage. i set up profiles for ac and battery.

if i just use TS for chipset clock mod and rmclock for voltage/clock, would it cause any trouble or conflict? thanks.

 

Is there anywhere I can download ThrottleStop, as the fileden link does not work (Connection reset every time)?

I'd be very grateful. Thanks

 

the link works

 

Hmm.. It appears the link won't work for me. It keeps saying connection is reset, been trying for a few days. Would someone be able to upload it to rapidshare or megaupload for me?

EDIT: ... aaand it now works. Heh. Havn't a clue why, unless someone changed something. Anyway, Thanks for the help.

 

ok so im running both TS and RMClock. no issues so far.

unclewebb, do you think i might run into conflict with both of them running TS (for chipset clock mod only) and rmclock (for voltage undrevolt and clock profiles)? thanks.

 

It's not a problem to run both TS and RMClock at the same time. Only use one program to manage your voltage and multipliers though.

I'm in the process of adding a safer and simpler under clock under volt feature at idle to ThrottleStop for Core 2 owners. Stay tuned.

 

unclewebb, thanks so much for your hard work on this.

However, I seem to be the only person who's finding that this is NOT solving my throttling problem on my 6935G. I never noticed throttling problems until a couple of days ago...

Without ThrottleStop, framerate drops dramatically, but to a new STABLE lower rate for a few minutes, and then goes back up, then down, then up... but always staying stable at whatever framerate for a couple of minutes.

When I enable ThrottleStop, as soon as throttling tries to kick in, I get weird "lurches" where the game will run overly fast for a moment, then pause altogether, then stutter, then run okay for a few secs, then stutter again and so on.

I recently upgraded to the latest Acer BIOS (V1.19)... Could it be that the new BIOS is manages throttling in some new way? Could those 6935G users who have had success with ThrottleStop tell me which BIOS version they've been using? And also, is it just the "clock rate" tickbox I should be ticking? Can anyone report success with V1.19 and ThrottleStop?

Thanks again everyone involved and especially unclewebb...

 

When ThrottleStop is enabled, the icon in the system tray will be red.

I don't know what or if anything has changed in the recent bios you are using. The biggest problem with these laptops is Chipset Clock Modulation. This needs to be set to 100.0% and that box needs to be checked. You can minimize TS to the system tray when gaming.

Turn on the log file option, go do some gaming and upload a log file to www.sendspace.com so I can have a look.

If you are experiencing throttling then try another test with the top 4 boxes checked including the multiplier and VID. Maximize VID first and then check this box before checking the multiplier box. I'm just about finished a TS update so this will be a little safer to use.

Post some logs so I can understand your problem better. I'll send you a link to an updated version of TS when I see some data. Hopefully the problem is just how you have things set up. If you're not sure include a screen shot of how you have TS set up with the log files you upload.

This post is for using TS on a Core i7 but it might answer some of your questions.

Hi,

Thanks again for taking the time... Okay, so I didn't have time for any real gaming, but I ran Orthos to stress the CPU... first with ThrottleStop running but disabled, and... nothing happened. The two percentages stayed at 100%, even though the CPU got up to 68degC!

So I guess I'm an idiot and have been wasting your time - I guess it's not throttling at all! Anyway just to be a completist, I then enabled the top four check boxes as you suggested and made this log:

http://dl.dropbox.com/u/4021321/ThrottleStopLog.txt

Weird though, as the symptoms that originally started me on this sounded EXACTLY like what was described for throttling, and even kicked in a the same temp that I'd read others complaining about (62degC)

Thanks

 

Most throttling only occurs when you are using the CPU and GPU at the same time. You need to be working both to test for throttling. You can do this by playing a game or you can do this by running Furmark AND Prime95 both at the same time.

68C isn't that hot for a CPU. When it gets to 100C then you need to be concerned but even then it can still go 25C or 30C higher before it will shut itself off automatically to protect the CPU from getting damaged.

 

Ah okay, thanks. Probably best that I go back to the offending game then (Race Driver: GRID)... I may not get time to try this out for a few days then as my gaming time is severely limited these days! I'll report back once I've tried.

 

No problem. If you ever want me to have a look at some new data just send me a PM if you want to get my attention.
I can never get enough user data.

 

Furmark AND Prime95 = instant throttle without TS.

 

unclewebb, is it possible you can make throttle stop support for Atom n270 CPU?
Thanks!

 

On the Atom N270, Intel disabled the internal high performance timers that the Core 2 and newer Core i CPUs have so many ThrottleStop features won't work correctly or at all.

What sort of features do you need with your Atom? With a TDP power rating of 2.5 watts, I can't imagine it does too much throttling.

 

Hi again unclewebb,

I managed to find time to do the testing with Prime95 and Furmark simultaneously.

With ThrottleStop disabled but logging - CHIPM intermittently dropped to 0% and the temp maxed out at about 71degC, and dropped back to around 60degC each time CHIPM fell. I think that means that my machine was definitely throttling, right? See: http://dl.dropbox.com/u/4021321/ThrottleStopLog(disabled).txt

With ThrottleStop enabled and the top four boxes ticked on default settings - CHIPM stayed at 100%, and the machine got much hotter. The last time I looked at HWMonitor, CPU was 81 degrees - then I looked away for a few minutes and when I looked back the machine had rebooted... Ouch! See:
http://dl.dropbox.com/u/4021321/ThrottleStopLog(enabled).txt

Two other bits of info for you:
http://dl.dropbox.com/u/4021321/Capture.JPG
http://dl.dropbox.com/u/4021321/Capture2.JPG

So what this seems to show if I understand correctly is that ThrottleStop is doing its job properly. If so, that leads back to my original post - for some reason in Race Driver: GRID has the following symtoms (copied from my previous post):

Without ThrottleStop, framerate drops dramatically, but to a new STABLE lower rate for a few minutes, and then goes back up, then down, then up... but always staying stable at whatever framerate for a couple of minutes.

When I enable ThrottleStop, as soon as throttling tries to kick in, I get weird "lurches" where the game will run overly fast for a moment, then pause altogether, then stutter, then run okay for a few secs, then stutter again and so on.

Any thoughts? Oh and by the way I'd like to make a small donation for you but I don't have Paypal (I cancelled after they ripped me off...) Any other way, e.g. Amazon gift list or something?

Thanks!

 

CHIPM stands for Chipset Clock Modulation and when that is not at 100%, that's definitely a sign of throttling.

One thing I noticed is that it seems like your on chip temperature sensors might be broken and not reporting correctly. They look like they are stuck at a very low temperature and will report the same thing at idle or at full load. You can try using RealTemp and its Sensor Test feature to check for this problem.

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

When gaming, you can use ThrottleStop to stop the throttling of your CPU but that might be forcing your GPU to start throttling instead. You could try logging for that with the GPU-Z program. You might also be able to set RivaTuner up to prevent GPU throttling. If you can get your CPU and GPU both running at 100% of their potential then you might get some smooth gaming out of your laptop yet.

Thanks for your offer of a donation but if you don't use Paypal then don't worry about it. I know you appreciate my help. You can help me by continuing to test and to find out why GRID isn't smooth yet.

If you run a ThrottleStop log and GPU-Z log at the same time while playing GRID then this might start to make some sense. Check the 4 boxes in TS again so we can have a look at what the GPU is up to when game play starts to stutter and lurch.

http://www.techpowerup.com/gpuz/

Edit: On a side note. I'm just about finished updating ThrottleStop for better Core 2 support. The next version will let you run low voltage and a low multiplier at idle and will also have the ability to switch between 3 different profiles. If you get RivaTuner to lock your GPU then you'll be set.

 

looks amazing mate!

can the profile be switched automatically? like, if its on AC, a profile with max performance (max multi) is switched. if its on battery, a power saver profile is loaded.

also, will we be able to set different voltages for ech multiplier like in rmclock? or just a low one (x6 ?) on idle?

one last thing, what do you mean by locking your GPU?

 

Hi again,

Okay I'll run the test in GRID as soon as I get a chance. Regarding the CPU temperature not changing - it seems to be a common issue with the 6935G, if you Google it you'll see lots of other people reporting the same issue. The other temps all change okay, just not the 2 CPU cores...

 

rna: A lot of users with a variety of laptops are having problems with GPU throttling. Some users have had success with setting up RivaTuner so it locks the GPU core and memory MHz at a fixed value. 5150Joker has some information about setting up RivaTuner for this purpose in the M15x thread.

http://forum.notebookreview.com/showthread.php?t=439546

It should be easy enough to switch profiles automatically when switching between AC and battery. I'll keep that feature in mind.

 

Hi unclewebb....

SIGH!!!!

I managed to find half an hour to play GRID... And guess what. Not a sausage. Worked perfectly... The framerate dropped as you would expect in busy parts of the game, but only as you would expect ANY game to do when in a particularly "intense" bit.

The other day though, the symptoms I described definitely remain true.

Here are the logs from this session, although annoyingly it seems the GPU-Z log didn't update while I was gaming - I needed to set a checkbox to tell it to keep updating when not in focus but overlooked doing so...

removing this as I have posted below

 

We should have a sticky post that it is unsafe to upgrade to the new BIOS from ACER.

1.14v is the safest at the moment.

I have two friends and another one MSN that confirm during normal use that 1.16v will start to snow *pixels go all crazy and *, this has nothing to do with over-clocking.

People should downgrade back to 1.14v, and we should make it known the 1.16 is unstable, untested, and even dangerous.

 

any news on new version? i'm really looking forward for it.

 

could you also provide some info about gpu lock? i'm having this problem, so i would like to know how TS would fix it.

 

Guys sorry I havent read the whole thing so I dont know if this has been mentioned already.

Have you tried installing Generic forceware drivers? Go to like guru3d.com and find the latest generic nvidia drivers for your OS. NOT laptop specifc drivers. This should stop the Throttling abilities of the GPU and should lock the mhz to whatever the max of the card is.

hna i was going to recommend you read this thread but looks like you found it already

 

Just a note Acer pulled the 1.16v bios from all there support sites for the 6920g

 

if you guys don't know, there is a new beta 2.0 version of TS. check it out, it's great!

 

I got TS added to startup by using the Task Scheduler method.

Only problem is that it doesn't save the options settings like "minimize on close" etc.

Anyone know how to fix that?

 

Where can we get the beta hna?

ThrottleStop 2.00 Beta 15
http://www.fileden.com/files/2008/3/3/1794507/ThrottleStop.zip

With some feedback from hna, I was able to get the C-States feature working a little better tonight.

 

Hi and thanks again to unclewebb, i tested the Beta yesterday, in general everything works fine, but there was one little thing i noticed, that maybe a bug.

If Throttlestop is Off, you can still check an uncheck the boxes e.G. Chipset, but the arrows are greyed out an the percentage stays at the number it was set with ThrottleStop On.
But if you pusch the greyed out arrows, nothing changes (ThrottleStop Off) but it seems that the change is noticed anyway.

Example:

Chipset 100% ThrottleStop Off Arrows greyed out. Box is checked.
Now if u push the down arrow few times its still at 100%.

BUT if you turn Throttlestop On the value changes instantly to the value it where as if the arrows weren't greyed out while pushing the arrows.

So i was wonderung (with Throttlestop Off) why the Percentage do not change and pushed the Down-Arrow very often. The Percentage said still 100%.

After Turning it On, the value was instant at 12,5% (because of pushing the greyed out Down-Arrow to often) and my System become so slow that i haven't another chance to reset ThrottleStop as reboot.

Now that i know this, this will not happen to me another time, but maybe to other people, so just as short note and sorry for my bad technical english...

 

Abraxis: Thanks for the bug report. Most appreciated. I normally never adjust the clock modulation settings to anything but 100% so I never noticed this before. I'll get that fixed up in the next release so when in monitoring mode you won't be able to access the control for this.

Edit: I think this should fix that problem you noticed. Let me know if there are any issues.

ThrottleStop 2.00 Beta 25
http://www.fileden.com/files/2008/3/3/1794507/ThrottleStop.zip

The chipset clock modulation adjuster has been enabled again in this latest version. There was a problem with this on my Dell laptop so I temporarily disabled it but it continues to work correctly for Acer laptops to prevent throttling.

 

Hello,
my probleme is a reboot when i use quickpar, it shutdown computer.
i have tried ortos and it shutdown about 30 seconds with ThrottleStop enable,
my question how setting it ????i don't uinderstand everything !!!
my computer : acer 8930g, quad 9000, 4go ram , 9600gt bios : 1.20
thanks

 

If your CPU is too hot or if you reduce the voltage too much, your computer will shutdown when using Orthos.

 

Hello, thanks
i thinks now it's the CPU too hot, because i haven't reduce the voltage !!!!
but if i use your programm with orthos : shutdown
it use with the user parameter (default)
have you got a idea ?

 

You need to show me some screen shots of ThrottleStop and CPU-Z so I can have a look at what you are doing. On a Quad Core CPU like a Q9000 you should be running Prime95 for load testing. Go to step 3 on this page and download Prime 95.

Free Software - GIMPS

Can you run Prime 95 on all 4 cores of your CPU without a shutdown? How hot does your CPU get when testing? If your computer is badly designed with poor cooling and is not stable then ThrottleStop will not fix that.
