I'm confusing myself do you mean 6x mem or 12x mem ? I rarely experienced better stability with CPU VTT and VDIMM so close - usually for me the ideal gap (depending on modules used) is between 0.3-0.4v difference between CPU VTT and VDIMM. But then I haven't tried 2GB density modules yet.

6x1GB @DDR3-1688Mhz 8-8-8-24 1T at 1.830v bios (DMM measured 1.835v real)

Bumped Bclk to 211 and reduced vdimm from 1.830v bios to 1.815v bios (DMM = 1.820v real) for DDR3-1688Mhz 8-8-8-24 1T.





Slightly faster 32M Pi times than 3x1GB D9GTR at same main timings even though below 6x1GB was done with considerably looser subtimings for tRFC, tWTP, tRRD and tFAW in bios. Will try tighter timings later.
