folding bottleneck?

post #1 of 6
Thread Starter 
hey guys,

i am currently folding with 3 5870s in my current system... one will run at full speed but the other two will only run at 1/3 of the speed if i have all three running... i am running them is a system with the same specs as my sig rig (but 5870s instead of 470s)... i was wondering if they are possibly being bottle necked by suck an old CPU or if something else may be wrong... any help is greatly appreciated

thank you in advance

Highly doubt it because running folding via GPU doesn't really affect the CPU at all if not by much if I am not mistaken.

For ATI cards, it does. ATI folding has a much higher CPU usage than Nvidia. There is a method to reduce it. I'll try to find it.

my CPU actually is only running at like 30-40%... i have tried this before and it does lower my CPU usage, but it doesn't increase the work rate at all because my usage is only at 60% max... do you know if there is some kind of decreased work rate wile using dummy plugs (since the 780i doesnt support x-fire)? i have been trying to figure out the problem for a wile now and just cant seem to figure it out... the only other thing i could think of is that they aren't getting enough power, but i can pull a steady 1200W, so i dont see that being a problem... the FSB of the 840d was the only thing i could think of it being, but it shows that i still have some more CPU to use
