Evga 780i problem

I'm building a system with q6600 and 8gigs of ram on this board with a 750 corsair tx power supply and the system doesn't boot with more than 2 gigs of ram in a single slot.
I get a blue screen error message with irql not less or equal message.

Does that mobo definitely support that brand and model of ram?
Also is your bios up to date?
 
Yeah, I updated the bios just the other day ago, and the ram is only list of recommended types ocz 6400 ddr2 sli.
The update didn't help.

Sorry don't quite follow you there - is it supported or not? Are any listed supported at 8gb?

I know I can't go above 4gb when I go for 1066 stuff as some weird incompatibility with my motherboard means you can only run dual channel and not fill all the slots. Maybe you are encountering a similar issue?

Another thing if it's bluescreening is make sure you have your memory voltage set correctly in the bios - a lot of mobo manufacturers under-rate this default by quite a margin.
 
Ummm, the model of ram is listed as one of recommended brands, and as far as it being an 8gig problem 4 gigs doesn't boot up either, tryed changing power supply got a 1st time boot up with all 8 gigs but since than same problem only one 2gig stick in any of the 4 slots. Mem test only fully responds with one 2gigs which it diagnoses working no problem, anymore than 2 gigs test pauses at 5 percent or so and nothing...
 
How much RAM does your motherboard support? If the motherboard supports up to 8 GB, and you have 4 DIMM slots, you can't put more than 2 GB in each DIMM slot.

Yeah two per slot

If each slot doesn't support more than 2 GB of RAM, that means that it won't boot properly. So you either need to get a different motherboard that supports more than 2 GB in each slot (very rare at the moment), or repace the ram with 4 2GB chips.
 
And you've rotated all the different ram sticks you have into that first slot to check each of them are ok?

If so then its kinda gotta be the motherboard at fault then - weird one though.
