Can I set the GPU load for folding? Temps are kinda high...

post #1 of 9
Thread Starter 
I just started folding and followed a couple guides and i think i screwed up somewhere because in the FAH control client, my gpu slots are paused and only my cpu is folding. So I went and got the FAH GPU Tracker V2 and configured it so that both my ref. GTX 670s would fold as well.

Now the problem is the temperature on my GPUs skyrocketed. I quickly used Afterburner to raise the fan speed to MAX and now they're at about 76 degrees C.

So my question is, how do I lower the gpu usage in order to lower the temprature? and how do i get the gpu slots in FAH Control to a running status instead of pause

To get your GPUs folding you will need to move the "Folding Power" slider to full.

You can't set GPU load. The BIOS/drivers/etc. for GPUs have never been made to have fine-grain control over usage, so it ends up being all-or-nothing approach. The best workaround the Pande Group was ever able to come up with was a duty cycle approach, e.g. 5 minutes of folding, 5 minutes idle, 5 minutes of folding, etc. They scrapped this because a) it didn't really help people's issues with lag, as you'd still be seeing lag 50% of the time (or whatever you set the duty cycle to) and b) its a lot more physically stressful for chips to see frequent, large temperature swings than it is for them to run at a high temperature for extended periods of time.

I would call 76C somewhat warm but nowhere near dangerously high. If this is causing your room to be uncomfortably warm, then that's a different matter. How old are these cards, and have you cleaned them recently? Dust buildups can cause GPUs to run several degrees C hotter than they would normally. In general, though, you will see temperatures in that vicinity when folding, as FAH pushes GPUs very hard.

Sorry I should rephrase myself, they get "warm" as you say but the fans get freaking loud, so should i just drop the speed and let them get hotter until i watercool them?

EDIT: @tictoc
I see... thanks alot thumb.gif

Only you can really determine what's too loud or too hot. What temps do your cards hit at, say, 75% fan speed?

My solution to high temps and loud GPU fans was to take the side casing off and add a 120mm fan to blow directly between both GPU's - dropped my temps by 10 - 15C and lowered the GPU fan speed. Just an idea.

Use v7, and fold the core 17 WUs, they are around 10C cooler on my 670s, and give ~95k PPD each vs 21-23k on core 15.

thanks you guys i really appreciate the help. After seeing my points daily, it makes me want to make a dedicated folding rig with my older/left over parts
