Spent a few hours tweaking now trying to run at 425x9.5 but can't get Prime blend to run for more than 60 seconds but no BSOD's under normal use (surfting, itunes, etc) - think i'm missing a vital setting that this board needs. Have dropped the multiplier to 8 to eliminate CPU issues and mem timing is loose at 9-9-9-28. Will post what I have later tonight but from memory I have tried Vcore is 1.375-1.395, LLC-DIS, VMCH 1.48-1.55, VTT 1.3, PLL 1.5 , VDIMM 1.94.

Will try EF's comments in red on Mike's earlier post tonight to see if that helps - thanks for those.

What is the common setting for DRAM Static Read Control, DRAM Dynamic Write Control and LLC ?

MikeMK - how did you discover the weak core and what GTL value was needed to correct it ?.
