Damien - I do not run 2gb strips, others do and some have reported problems.
I have similar gskill memory as you but the 3x1gb (2k) and they work great.
One thing I noticed when setting the bios to use xmp - gskill has the xmp set to run the qpi/vtt all the way up at 1.5 to 1.55v!
So - 1st question - have you tried with xmp on?
Then 2nd question - have you tried with high qpi and mem v - for testing and even over night - 1.55 qpi and 1.84v memory v will not hurt you.
I would recommend that you keep qpi and mem v within .5 volt of each other.

i'm not sure what you mean when you say 2gb strips. im assuming ram modules?

anyway, your advice helped a bit. my qpi/vtt is one voltage setting and the highest it can go is 1.495v, so I set it to that. set my ram to 1.66v and my cpu pll to 1.9v.

booted at 798mhz just fine, farther than I got before. Except...only 2 sticks are showing up? check the Screenshot. CPU-Z looks good but everest and windows are reporting 4gb... i think something needs RMA'd here or i'm really just missing something. I want to think it's the advanced ram timings that I need to mess with but I have no idea what to even consider making them..

ALSO, I'm not so sure everest and windows are reporting wrong, because the bios splash clearly said 4gb checked out. it also said 2gb checked out on a few reboots. going back to stock settings, it shows 6gb checked out and everest and windows both showed 6gb as well.
