I've been testing my cheapo Crucial memory today. It runs quite nice at high vdimm

At 2,55v it does DDR1200 CL4-4-4-9

Setup:

Intel Core 2 Duo E6600 @ 3725MHz (TTBT cooled)
Biostar TForce P965 w/vdimm mod
Crucial BallistiX PC5300 CL3 @ DDR1240 CL4-4-4-9 2,8v

Mem contains Micron D9GMH.

I'll do some more testing later this week
