Really have to play your own game with voltages, for example i'm stable @ 4.3ghz with 1.456v, but i now know i'm also stable @ 4.2ghz with 1.37v (perhaps less, not finished testing). So there's no way i'm going to set a whole .08v higher for only 100mhz extra when the clock is already so high that it won't make a difference to me personally.

Please do post your bios settings though, can't figure out why you need such ridiculous VTT. When i started to find max bclk all i did was:

Bclock 200 (my starting point as i knew it was stable already)
CPU Multiplier 12x
Uncore Multiplier 12x
QPI Multiplier 18x (36x in bios)
Memory Multiplier 6x
Vcore 1.275v
VTT 1.46v
Vdimm 1.64v

Then i started raising bclk until i hit walls. Under this setting your roof is only going to be how high your QPI clock tops out - meant to be around or just under 4ghz.
I'll give this a shot as well. Iirc I did try it when I first got the chip and I couldn't go over 200 Bclk with 1.46vtt. I then raised it to 1.55 and was able to hit 205.

Anyways, I'll try this again, maybe I missed something

I am running 6 x 2GB memory, so would that require a higher vtt?
