New to multi-GPU folding, quick setup questions...

You don't need SLI enabled. If you are using Vista or 7, dummy plug isn't required either with 191.07 or newer drivers. I run with and without SLI enabled on a single monitor, no extended desktop and no plug while using Vista Premium 64.

Your board is SLI capable though, will it still work on an older non-SLI board like the P5K.

If it won't work and your monitor has dual inputs just plug both cards into it, if not just grab a dummy from Perineum.

Another way is to just use the monitor from your main rig to get it running then swap it back...

I ran two cards (GTS250 and 9800GTX+) on my old Gigabyte board that was not sli, and no dummy plug.

there is hack to enable sli on all non nforce motheboards if anyone is interested Making SLI work on ANY non Nforce chipset MB - XtremeSystems Forums

That's why I said I run it both ways, so Caldezar would know it worked. I have found that my PPD went up slightly while SLI was disabled. Plus when it's disabled I can game on GPU 0 while GPU 1 is still folding away.

Sorry I didn't explain myself well, what I meant was with your board it can still use the SLI capability to communicate even when you are not using SLI.

I didn't know it would work on an older non-SLI board as well, thanks for the info gents...

I tried the no monitor or dummy plug with my i7 860 board and found I would get a ppd drop on the non-primary cards sometimes, luckily my monitor has three inputs which fixed the problem...

You can't SLI or fold without the SolyTech SL-C350ATX 350W

If only I knew where to get my hands on one...



Thanks for all the reply's gang! I appreciate the help! I've already ordered the GTS250's through work and I got a good deal on a PSU here on the site. So now it's just down to shipping on both sides. When I get the gear in a week's time or so, I'll set it all up and see how far I get.

So to summarize, I don't need SLI or dummy plugs, nor do I need a second monitor at any stage. All I need to do is install the cards (separately with 2 separate driver installs? Or together with a single driver install?) then set up 2 GPU clients with extensions as noted in the linked thread.

Also curious, the thread that was linked shows the GPU's listed as GPU 0 and GPU 1. I assume this is a Windows default? Or does that need to be assigned?

Which GPU is 0 and which one is 1 doesn't matter. All that matters is that each GPU is assigned a different number, so that F@H doesn't try to run multiple clients on one card.

Not sure on how to install without using either a second monitor input, or dummy plug, but as far as the drivers go.... install one card w/drivers, and the second card with grab the drivers when you physically install it. (no need to re-install the drivers for successive cards).
