DFI LP UT X58-T3EH8 - First bench, bios screens etc

[d3885u]

Hi...is there somebody could help me with this kind of trouble...
I'm using i7 920 right now (S**K batch 3836B037)

When I'm using Biostar T-Power X58 I could make my procie run @ 3,8ghz BCLK 200x19 and RAM @ 1600 8-7-6-15 trfc 60 Uncore 3200
with vcore 1,312v (LOAD), vdimm 1,62v, vtt/qpi 1,34v
But now with my DFI UT X58 I can't run at that speed anymore coz I'd always had randomized BSOD and restart itself when I test with Prime95...
with the same setting or even I pushed my voltage more than that, but I still having that problem...

Please somebody help me...
