I've tried the blue & the white slots. White do 1200MHz w/2.1v, but the system doesn't seem stable. Blue can't reach 1200MHz, even with 2.55v.

Got some clues?

Thanks in advance
I am having exactly the same problem with my Ballistix 8500 too.
I'm using 0505 BIOS.
1200 on white slots = not stable. On blue slots = cannot boot up.
Tried with different vDimm, vNB (as high as 1.7v) and subtimings, still not stable.
My Teamgroup 6400 seem to do somewhat better with the same settings.
At least they have passed memtest 600% 1200 @2.2v.
