Folding on Core 2 Duo + 6970

post #1 of 7
Thread Starter 
I'm starting to get into more serious folding, and I have recently upgraded from the v6 client to v7. Before, I folded very sporadically on the GPU only, but with the v7 client having everything together I tried running SMP + GPU simultaneously. The GPU seemed to do pretty well, but the CPU didn't seem to be getting anywhere at all. I heard on this site that you need at least one CPU core to "monitor" the GPU folding? Would it be worth it for me to fold on my dual core at the same time as my 6970?

Also, is there any reason to go with the v6 client over v7?

Thanks in advance!

Folding with an AMD card does take up one whole core to run, and the AMD card won't even net too much PPD. I get about 9k on my OC'd 5850

I run both my smp and gpu client, along with the registry fix to only allow the client to use 5% of the total cpu to drive the gpu folding. Ill find the registry fix if you want to see how it goes.

That being said, I have another 24/7 rig with a Athlon 64 x2 3800+ and I dont even bother with smp, even when running a Nvidia card, its just too slow.

His 6970 would give around 9k PPD probably or thereabouts at stock, which isn't too bad, but currently they suck in terms of PPD-per-Watt until the client is improved.

Yeah, I certainly wish they would net more. Oh well!

Yeah, that's what I was afraid of. I think I am getting around with 9K ppd with it now, I just thought I might as well throw the CPU in there as well since I was running it anyway. But the WUs its giving the 6970 are finishing in about 8 hours IIRC, whereas the CPU was sitting at about 24 hrs.

I wasn't expecting great results on an AMD gpu regardless, but I did set the flags to get the new OpenCL WUs for it. I hope that once they've been more developed, folding on AMD gpus will become more worthwhile.

I'm also considering getting a low-power nvidia GPU for exclusive folding in my second 16x slot. A GTS 450 perhaps?

a 450 will get you around 7-9K depending on overclock... and will make very little difference to the SMP folding

Awesome! Thanks.

EDIT: I'm actually waffling between the GT430 and GTS450 right now and I happened to notice you have a 430 in your sig. How does it do in PhysX and folding?
