I think it is impossible to get 4ghz UCLK on my chip with 1.35v QPI I don't want to damage my chip.
you should be able to do 1.41v for your QPI voltage (seeing as according to others who have measured, it get's to about 1.39-1.4 by the time the voltage hits the components it's controling). seeing as you're running 12 gigs of memory, you may very well still need the voltage in QPI for it to be stable. try 1.38-1.39 for QPI and stick between 1.5-1.75x ratio for your uncore to start with. the higher you go, the higher the strain but the better the performance. also try to keep QPI link around 6200-7200 range. any more than that and you may not post on startup... atleast stable that is.


at the moment i'm gonna have to agree about the whole hardware matching with this board. at the same time, i'm going to go with the much larger crowd that points at the board to be the issue as it's a prooven statement when said hardware works just fine at whatever settings on other decent boards but come to this specific one...

i'll deal with 1866 being my cap for the time being and just wait for the 2011 boards to come out this fall. i think i might get away with using my G.Skill ECO's then if nothing changes with DDR levels. 1600-1800mhz at CL5-6 timings sounds pretty darn nice if you ask me. specially on 4 channels of memory.
