I had recently killed a P5K-E and replaced it with a DFI LP P45 TR2+, I have not had much of a chance to overclock it until now and I cant get close to where I was with the ASUS board. With the ASUS board, I was 3d stable 24/7 with 3.6 (450x8), and I could do pi runs, and 3d bench to 3.8. With my DFI I can get 3.4 stable 24/7 but I cant even get 3.5 to run 3d mark, and anything above 3.55 wont even run spi 1M. Suggetsions?

Current Setup:
Q6600
Tuniq Tower.
Corsair Dominator 1066 5-5-5-15 (good up to 2.3v)
DFI LP P45 TR2+
4870 1 gig
PC Power & Cooling 750 Watt Psu.

To hit 3.5ghz I run:
1.328 vcore (+150 mV in bios)
2.2 vdimm
1.37 NB
.63x/.64x on the cpu refs
.67 on the nb ref
8x multi
440 fsb
I forget the exact memory divider, but I think its 5:6 in cpu-z. I ran memtest overnight with the ram at 5-5-5-15, 2.2v, 1059mhz and it passed with no problems what so ever, so I do not think it is a memory issue. What it may be is the CPU was damaged when the ASUS mobo died, the graphics card may be damaged from the crash (everything works fine at stock however, no issues what so ever), but that would not account for super pi and prime 95 errors at higher clocks. Any suggestions?
