GPU throttled back due to heat?

Just today I've noticed that my games weren't performing nearly as well as it was yesterday. Fraps is saying that my Rainbow Six Vegas and Neverwinter Nights 2 are all running around 20 fps. This is odd since everything was working fine last night. I ran 3dmark06 at default settings and it gave me around 2500 points. But today is a really hot day as ambient temperature is 27 degrees celcius and my gpu is idling at 87-88 degrees. Then i noticed that my fps is around 40 when i first started neverwinter nights and as the temperature climbed to 96 degrees my frame rate would gradually decrease until around 20 and remain there as well as my temperature staying constant at 96-97. So is the gpu being throttled? I've also read about other ppl's g1s gpu temperature reaching 110 degrees, so what is throttling mine? could it be the ntune that i installed last night?

 

Idling at 88? Ouch, that's pretty high. Are your fans working and not clogged?

Remove nTune and see what happens.

 

It shouldn't be cloggged... this laptop is only 3 weeks old. And it was idling at 80 degrees just last night. But I uninstalled ntune and it didn't make a difference.

 

My s96j freezes during gaming sometimes because the GPU gets really hot. Used to happen frequently but I took a can of compressed air and spray my vents and it happened A LOT less. Still happens occasionally, but cleaning it of dust really helped.

But idling at 88 is REALLLLLLLLY high...

 

Hmm well I brought it to a cooler environment (ie friend's basement) and its back to idling at 80 but the performance is still pretty bad, no idea whats wrong maybe i'll contact asus on monday.

 

Hy, sorry to bump this old post, but i've exactly the same problems as this user, when mi GPu reach 96 degrees on load BANG! performance drops sustancially, any ideas? I've undervolted the cpu to get less heat around the laptop and i'm running an orthos and another stress test to the GPU and everything seems to be fine (No fps drop) but I'm not sure if this is normal or I should call asus to pickup my notebook (Avoiding homemade solutions like the undervolting one)

 

I've finished the tests, They're not really a fps drop, It's like minor slowdowns, I mean, I gets a bit slowly 1 second and then continues normally, then slowly 1 second and back to normal etc.etc.. I've monitoring Hz both for the GPU and CPU and they don't drop during all the tests, any ideaS?

Edit1: I've Upload to youtube.com 2 videos to explain what I mean:

The GPU going fine: http://www.youtube.com/watch?v=Kl3e6RSvI70
The GPU afeter 5 minutes on the test: http://www.youtube.com/watch?v=nMfSrLNXtQo

Did you see the diferences? Can you notice the slowdowns in the second video?

I Need Some Help!

Edit 2: Is this the famous Stuttering thing described in this topics ?:

I remember this issue being mentioned, but I don;t remember a solution (happens many times with me). Try searching for similar threads.

 

So... Similar threads like what? The ones I posted?

You've said that this had happened to u, it was during long gameplay, or when? Thanks,

 

No, didn't happen to me. What happens to me often is that I remember issues being posted long ago, but I never remember the solutions. Perhaps there weren't any but I can't be sure.

Yes, similar threads to this / gpu throttling heat / overheating / try related keywords etc.

 

i just wanted to mention for the millionth time. All the notebooks mentioned here do not have any inherent overheat issues. Whatever your temps are they are normal unless you are overclocking, using fan modding software, or the notebook was not assembled properly (s96s for example needs to have the thermal pad tape removed before assembly). aside from that i would blame your issues on everything else but heat especially if it is a new notebook. We handle on average 20-80 rma's a month (as of 2007 most are old out of warranty notebooks). of the notebooks that came in due to heatings issues all were old and completely clogged with junk in the radiators. do not blame issues on heat. Asus thus far has not made any notebooks in the states that OVERHEAT without aid from the users or old age. C90s s96s g1s g2s are included in that fact above.

 

Well, it all depends on each person's definition of overheating. Or is there an official definition?

 

I just looked at the video and thats the exact problem that I have. I did contact Asus before and they told me to send it in but I have yet to do that because I didn't want to be without a computer.

 

Interesting, Tangerined tell me the results once u've sended and received the computer form Asus, anyway I've reading on this and most people agree that with the 163.67 ( http://www.laptopvideo2go.com/forum/index.php?showtopic=14932) drivers from latopvideo2go these problems dissapear. I've installed it and It's true instead of a full slow you get some less perfomance on a low framerate. Try it and share your results .

P.D.: What exactly did you told to Asus? "Hello, my computer is performing low on games" or what?

 

I also have exactly the same issue with GPU as the poster and KLaiN. I have been testing different drivers and I currently use 167.45, but the problem still exists.

I have been monitoring GPU temp with RivaTuner (shows temperature changes over time) and max I've so far seen is 108°C. It's constantly around 100°C (less than 90°C if game is not very GPU-intensive, like old Battlefield 1942) when gaming and gets down to 75°C when being quite idle.

These "slowdown peaks" seem not to be strictly related to high temperature, sometimes it takes just 15 mins and sometimes over an hour for them to appear. So I guess it also might be that known 8xxx GPU problem that KLaiN linked earlier. A true "gaming" laptop this is..

 

Did you try the suggested 163.67?

 

Yeah, try 163.67 works fine for most people (incluiding me), the problem it's not heat releated but anyway your temps are too high, the max my gpu reach it's 98º (Even after an hour playing) and it's at 64-67º at iddle.
