DFI 754 UT max 3.4v vdimm?

[PanaBob]

Quick rig specs:

DFI 754 UT w/ modded BIOS for vdimm
3200+ Clawhammer
512MB Corsair BH-5
510W PCP&C w/ 3.3v rail at 3.65v
idle around 0C w/ TEC
92mm fan blowing on RAM area
80mm fan blowing on mosfets

seems the most vdimm I can push is 3.4v
while benching it fluctuates b/w 3.25v and 3.4v so 245Mhz is my max solid OC. Screenshots at 265Mhz 2-2-2-6 are worethless with no stability. Is anyone getting more vdimm with this board without a DDR booster?

You need to have your 3.3V rail at least .3V above what you want to set in the bios to get stable voltages on that setting.
