CPU and GPU Folding?

post #1 of 6
Thread Starter 
I'm folding with the machine listed below. Currently i'm trying to complete my 10 smp before I switch to bigadv WU.

Should I Just fold with my CPU or change the SMP to 6 threads and also fold with my GPU? From what I have read folding with the GPU also requires some CPU power.

Thanks in advance!

You could try -smp 7 with your GPU and compare PPD vs just -smp 8. A lot of people say they get higher PPD with both, as the GPU more than compensates for the lost points from one thread.

Im using the v 7 client and I can only change the threads in multiples of 2. I will try it for a few days and compare points though.

Can you only change in multiples of two? I know that when you use the arrows it goes in multiples of 2, but I think I was using SMP 3 and folding on my GPU for a while with the v7 client.

edit: I think if you enter "7" in the box it will work. Could be wrong.

The reason it says by 2 is cause certain work units will instantly fail on 7 threads, to be honest nobody really notices it but eventually if you fail enough it could hurt your passkey ratio.
Those in the beta team have been suggesting to move away from these work units and already had a few removed, so hopefully they stop showing up all together.
