SMP folding on AMD FX 6/8 core

post #1 of 9
Thread Starter 
My next rig is going to be an AMD FX based system. I will be folding on it, SMP & GPU. I'm trying to decide which processor to get. I'd prefer an 8 core, but I keep hearing that folding SMP with 7 threads is...bad. Would I be better off with a 6 core folding on 5 threads, or the 8 core folding on 6 (yes, captain obivous, 6 is better than 5 lol).

Folding on an odd number of cores above 3 isn't recommended.
post #3 of 9
One of these days I'm going to have to put my 780 & 680 into one machine and then put up two separate VMs--each folding a separate GPU and a single core--and see what the results are like.

Has anyone else done this?

I've never tried to fold on a GPU in a VM in general... Never had any host software that it would work on.

So, if I went with, say, an FX 8320, I would set CPU to 6 in FAHControl? I guess 6 cores isn't enough for bigadv

With the time limits on the bigadv, you won't get even close with anything less than 16 threads...at least that's the rumor and what the threads I have read have said.

You're not going to be doing bigadv at all. The only way you'd get a single socket doing bigadv is with a ~5GHz 39xxK/X, 49xxK/X or new Xeon E5 V2 chip. Recommended is at least a overclocked 2P LGA 1366 Intel setup. Or a 2P/4P AMD G34 setup.

Dang, they've really changed things since I was last into folding. Back then a 4.8 oc'd 2500K could do bigadv. SMP6 it will be smile.gif

Yeah. It's a bummer frown.gif. It was awesome being able to do bigadv on a 2500K. That was when I got back into folding and it blew my mind.
Before that I folded on my tri-sli 9800GTX Q9300 rig... That thing was a furnace!
