Hi roboguy, I'm really sorry, but it's a bit hard to understand what you're saying. Why not just try building the SLI array and see if it causes your PC to freeze?

Hi I have a P7P55D EVO board brand new and I also have ram problems. I have the i7 860 2.8mhz cpu and 8 gig of corsair 1333mhz ram. My computer freezes for no aparent reason. This is random but is getting worse. I pulled out all the ram and am running with 2 gig for now till i figure this out. I still get freezes but not as many.Is a mother board thing or a ram thing? I am about to order some patriot ram and try it.

Any suggestions...

I've been getting the same problem with a P7P55D-EVO. From what I could read online, I've tried to do this two things:
1. Update the BIOS to the latest revisions
2. Set the correct dram voltage

The problem with #2 is the P7P55D setting the default voltage to 1.5V when using the '[Auto]' setting. My RAM is 2x Corsair XMS3 which has a spec of 1.65V. So using the default setting of the motherboard doesn't produce stable result, hence could easily result in the computer freezing.

The step #1 is pretty obvious... when you read the changlog of Asus about the latest BIOS update for this motherboard, you'll notice two of them being release to "improve system stability".
