New to this - SMP vs GPU folding

post #1 of 46
Thread Starter 
Hey guys I am new to folding, just started last night and my comp went to sleep (doh!). But I'm back up and running today, my question is if I don't want a small oven in my room and was going to pick between cpu folding and GPU - which should I choose?

Right now I have the SMP client set up and it's chugging away, but if I am not gonna fold 24/7 which would the most beneficial?

I am also wondering if I was to go to GPU folding, would I have to disable SLI in the Nvidia control panel?

Thanks

The i7 will put out big points if you fold -bigadv 24/7, but it'll take more than just days for it to complete the WUs and get you the bonuses/in before deadlines. The SLI 460s are also good for some serious PPD, SLI does not need to be disabled, but you need to specify which card each client runs on via flags in the shortcuts. The GPUs will provide alot of points, but they'll run 100% usage, so heat and fan noise may be an issue. For on and off folding, GPU is probably the way to go, the deadlines are a bit more flexible than -bigadv.

What about folding over night? SMP? or GPU's? At this pont I don't envision myself doing gpu and smp 24/7

Well it's entirely up to you what route you want to go. There will be significantly less waste heat if you do SMP versus GPU folding. When I've got two of my 470's running its rather warm. With all three of them my downstairs is nice and toasty. If I want a lot of points and little heat I go with SMP or bigadv.

If you want a decent amount of points I would suggest doing a bigadv once a week or something. You would need to leave the computer on for two days straight but then you could do whatever you want.

You can probably do both, just dont fold bigadv on the smp client because if your just running at night your most likely not gonna make any deadlines.

How tight are the deadlines? Also does anyone know who much clock speed will affect my ppd and overall output? I ask because I am thinking of lowering my OC down to 3.6 or so just so I can keep my temps in the 50's. I know i can go higher but if I'm just going to leave it cranking away I'd rather not have it in the 65-70 range.

Do you mean don't do the regular SMP? will one bigadv be enough for the week?

Sorry for the train of questions

If you're only folding overnight or something, just do GPU folding. I feel it's more worth it. I think the i7 will pull a bit less overnight.

Thanks for the advice!

-bigadv will take just over 2 days, if you do not use your computer for gaming or watching movies during that time.

GPU clients will spit out a WU every 3 hours or so.

A normal SMP client will spit out a WU between 4-8 hours, depending on the size of the unit.

Therefore, if you're going to be folding at night, it's best to run the SMP client + GPU clients. You should complete about 5-6 units each night.

Hmm I guess I could just leave it on when I'm at work as well, but I'm nervous as I can't use log me in from work. Any other way to monitor if its working other than waiting 3 hours for F@H to update?
