First off all memory has been run one stick at a time and passes 1 round of memtest86+. I did have one bad stick and sent the whole kit back; the replacement kit showed up the other day from G.Skill and those sticks tested and passed.
I'm running an Asus rampage ii gene with two 6GB F3-10666CL7T kits and an i7-920 D0. If I just set everything to "auto" and QPI-DRAM voltage to 1.35 then it will run with all 6 sticks installed at 1066. If I leave the QPI-DRAM voltage on "auto" then it won't boot into windows. So setting QPI-DRAM to 1.35 gets me up and running at 1066 on the ram and 2.6 on the cpu. Using hwmonitor shows all temps are fine.
However, if I set the bios to use the one XMP profile which I think is 7-7-7-18 1.5v at 133 then even with QPI-DRAM set to 1.35 it won't boot into windows.
I know that I'm using 2 of the 6GB kits but my understanding was that the XMP profile was just supposed to work and that upping the QPI-DRAM voltage might be needed because of running 6 sticks (instead of 3). I also tried not loading the XMP profile and just setting the ram setting manually but the result was the same.
Any ideas? I've no idea why I can't do something as simple as set the XMP profile, set the QPI-DRAM and be good to go. Do I need to go higher on the QPI-DRAM? This is supposed to be the easy part since it's just supposed to work.
Any help would be greatly appreciated.
