Precision M4300 GPU Auto-downclocking

Yo! It's my first post here, be nice

I have an M4300 notebook with a Quadro FX 360m as the GPU. Now, my problem is that it is automatically downclocked by about half after it reaches a temperature of 85C. I *would* be able to play Crysis (low, of course) at around 30 FPS if it weren't for this.
I thought it might be a BIOS problem; therefore, I downgraded to A02 (I had A13), but that didn't work, so I upgraded again.
I thought maybe it was the graphics drivers; so, I installed the next lowest ones, but that didn't work either, so I re-installed the newer ones.

Any ideas? It's intensely irritating

 

These temperatures are way too high for the GPU.You have somekind of problem.Is your fan working? Check if it's not full with dust or something and clean it good ..With the ffan ON your temperatures should not be higher than 75/80C

 

Both you guys disappeared from the forum after this interchange. 85C shouldn't 'downclock' the GPU...its software, somewhere...find out what yet?

 

lol... it took so long for anyone to reply I stopped checking. Anyway, my fans are working fine, no dust, and I even have an Antec notebook cooler running on high, and it still reaches 85C fairly quickly. And I'm not so sure it's software anymore, because it happens in both XP and Ubuntu. In XP I have Dox Optimised 182.05, and in Ubuntu I have some 177.xx drivers (can't remember at the moment).
I tried having RivaTuner force Performance 3D constantly, but that didn't work either (still downclocks to low power 3D).

BTW I had my motherboard replaced by Dell (different problem, fixed now) and it's happened with both.

 

Dude, i had an M4400 and i got this problem, too. But a little different from yours. Mine is GPU auto downclocking when i am not playing games or other 3d progrems. I got a solution by modifing reg files. If you still interested in this problem, you can add my msn [email protected]

 

I can't get my GPU over 74C when gaming long and hard....in another forum here, there's talk about flaky Nvida GPU's being put out, all heat related. Can't find the link right now. I would have gone ATI had I been given the choice, but I don't have any problems. I think it's luck of the draw.

 

I doubt it's a flaky GPU because it's happened with both the original one and the replacement. The M4300 probably just has crappy cooling. Oh well.

 

I beg to differ....the GPU is the variable here. The Precisions are all built the same, and most of us don't have cooling problems. Just correcting your logic here When I say most, according to DELL, not these boards.

I'd sure get it replaced again one way or the other...tell them to call me, PM, and I'll read them off my temps under load

 

I know the GPU is the variable. It's happened with both the original GPU and the replacement GPU. The tech didn't replace just the motherboard and not the GPU.

If that's not what you meant, then I'm lost
I'm fine with it, anyway, unless there's a software fix. It's not like I game a lot.

 

The GPU is soldered on the motherboard,so changed motherboard means changed GPU(on dell laptops). 85C is really too high for the GPU,it's possible that it downcloacks from bios becouse of the high temperature.I don't know what's the reason for these high temperatures.How did you chech that there's no dust in the fan.Mine seemed completely clean before i disassembled the hole laptop and found a huge amount of....waste inside the cooling.
If you're with XP you can also consider using RMclock utility.The voltages of the cpu in laptop are set waay to high in this laptop.Mine got a lot cooler after setting a stable lower voltages for the cpu.
