tRP --------------------- 7 ---------- : 5
tRAS ------------------- 20 ---------- : 15

MCH/ICH

MCH Reference ----------- 0.760V ------- : [Auto]
MCH/DRAM Ref ------------ 0.900V ------ : [Auto]
ICH I/O ----------------- 1.500V ------- : [Auto]
ICH Core ---------------- 1.100V ------- : [Auto]

I would try swapping out your PSU(even though it's a decent one) for something a bit heavier. These boards seem to be a bit power hungry.

Oh please don't be silly, his system won't stress any halfway decent PSU, and besides, we are talking "BOOT" here, not load in 3D mode

OP, does each stick boot in isolation in DDR3_1?

I can assure you that I wasn't being silly! I am using a GA-X58A-UD7(the next one to yours) and I couldn't get it to boot with a decent 750w psu. I had to put in a Corsair HX850 to get it stable. Anyway good luck with your new build, I will watch with anticipation.

+1^^ I think it is a power issue. He has memory voltage and MCH voltage in the ballpark, he could list his memory strap for us tho.
