Also, your vtt/qpi will need to be 1.5v-1.55v to start to run high memory clocks.
***edit***
Also there's a funky relationship between vtt and vcore on this board for it to post depending on cpu. For eva it was .27v- .31v on one cpu on the other is was less. For me it's .20 or less. You'll need to get that figured as well.
Thanks for your efford nemesis. I too was wondering WTF went on about this overvoltage thing reported in Smart Guardian, so you are saying SG reports crap and the voltages set in bios are pretty close to actual? I sure hope so.. gotta measure it, where can I find the spots to measure on?

The strange correlation between VTT and Vdimm I noticed as well, for instance if I go too far up or down with Vdimm while leaving VTT the board will only post showing 4GB instead of 6. The range on my current 920 seems to be 0,25-0,3V difference between the 2.

And yeah I tried 1,55V all right, went as high as 1,65V with some CPUs, to no avail. And remember I am not talking about 2Ghz+ here just stupid 1600Mhz. Impossible with normal/low volts... if I feed it 2V Vdimm then sure it'll do it.. but I sure as hell ain't runnin 2V for 1600Mhz.

It's also not the uncore speed, I just upped the uncore to 16x at 210 BCLK and its still linX stable at 4,4Ghz, no change whatsoever. Changing the ram mult to 8x causes the system to freeze on boot

I'll maybe play with it some more tomorrow, and I wouldnt be complaining if I had trouble hitting 2Ghz+ ramspeed, but we are talking officially supported 1600Mhz here. Somehow I feel like an idiot running 4,4Ghz with HT rockstable but running the memory at 1200 something

And I ain't exactly new to OCing or to DFI either, to say the least... tried 5 different CPus so far and 3 different mem kits. Maybe I need to try a kit with XMP profile or something, cause the ones I tested were all CSX and they don't have XMP or anything.
