C-N .. just wondering about your hypers @1067mhz.
do they also freeze 32m on w7 ? what about P95 on W7 ?

if you get 32m errors from lowering vdimm on w7, and not freezing then looks like same issue i have with my corsair

my OCZ don't freeze on vista 64 and XP, but > ~1050mhz on XP my corsair freeze 32m unless i raise vdimm up to similar level that ocz needs.
the corsair is higher bin than ocz, so the corsair min vdimm seems due to 'other' factors (idk )

also my corsair won't run @ default vtt, only @ 1 step lower (was your tip)

i didn't find an elegant solution for XP, just vdimm to avoid freezing 32m


btw, tried f6e bios
apparently my chip now boots 2 extra multi before i need int. pll enabled.
1.5v vdimm setting is fixed (now just normal overvolting)
