i have a 2500k 2 x hd6870 just starting to fold on the gpu's is it correct that you have to disable a core on ya cpu for each gpu you fold on, if so how do i do this on fah7 , is it in the expert settings under "extra core options" if so is the following the correct code smp4-1 (for 1 gpu) smp4-2 (for 2 gpu) Ross
Not entirely. I normally run on all cores but cap it to 80% to give it some head room. One core disabled will be plenty if you had to.
ive was setting the affinity in task manager, but when it starts a new WU its goes back to all cores..... ive trying getting the smp to use 3 core with any look
ATI GPUs use a full CPU core when folding, NVidia GPUs barely touch the CPU. So to use 2 x 6870 you will probably only be able to efficiently use 2 CPU cores for folding. Votick's reply would be right if you were talking about NVidia GPUs.
