Hey guys, I have a few questions

1) What's the word on VTT and DRAM voltages? Is it to just keep them within 0.5v of each other like the guys from bit-tech say?

2) Can someone give me some general settings for a 3.2 (20 x 160) Ghz oc on the 920? (I know it's weak, but it's plenty enough for my needs)

I was thinking:
Vcore - 1.2v
QPI/VTT - 1.2
DRAM - 1.5 (since I'll only be doing 1280 Mhz)

Appreciate your guys' help!
