Hey guys,

got it sorted out - one of the Ultras 8the middle one) is defective... plugged them all in one after another, and this one gives the nvkpll... bluescreen when booting. Sucks but it's better than a dead mobo, I guess..

Anyway, VERY impressed with the performance so far, this really is something entirely different from 680/780i.
Hit 19950 3DMark 06 with the 2 Ultras at stock clocks ant the QX9770@400*10 - even running 2T mode (mem at 1600@7-7-7-20 sync).
How much NB voltage does it need to run 1T at 1600? Tried 1,4 but it froze after 10 seconds in windows, lol.
