I have a evga 780i ftw, with 4 gigs of 0cz pc 8000 SLI ram. I want to go with a 64 bit Win 7 OS. So I want to put 4 more gigs of memory. I found 4 gigs of pc 8500 ocz sli ram. Will these two pairs be compatible? Will I need to change some bios settings? here are the specs of both rams.

You can try but I do not recommend you mix modules, specially on a 780i.... Why dont you buy 4 more gig of the same ram you have now?

Because I found a good deal on this memory. I will probably just keep looking for a good deal on some more pc8000. Someone on another site said 4 gigs is more than I would ever need, but with a 64 bit it seems like 8 gigs would be pretty good.
