Anyone else getting this with SMP and GPU3 folding?

post #1 of 7
Thread Starter 
I'm not sure if this has been asked (I have probably asked it before =/ but couldn't find anything on the search).

I'm getting weird usage on my 470 once I start SMP.





Is it simply that my CPU can't keep the 470 running at max whilst it's running SMP as well? Or is there something inherently wrong with my system?

I've got rainmeter and rocketdock running in the background, but nothing else (if that makes a difference).

Any help is appreciated

Yes aero is enabled, but it doesn't do this with just GPU folding.

The way I fixed this problem with my GTX 480 was to set the FahCore_15 to real time priority. (you could probably get away with High or anything above what the SMP is set at)

My guess on what was happening is the GPU client and the SMP client are competing for CPU time; the GPU client has to wait sometimes, and that causes the small drops in GPU use.

Also, it seems to drop like that when you scroll up and down on a webpage or do other graphical stuff... The GPU3 client is good at throttling back to let you have smooth performance for windows.

Ah makes sense... *goes and tries increasing priority*

It worked! Thanks k4m1k4z3! It's at a stable 99% now.

That is only a temporary fix, you need to use a program like Setpriority or leave one core for the GPU using the -smp 3 flag on your SMP client.
Check out the Setpriority guide.
