You right that this is the first Intel with an IMC. But! Intel specifically says all 1366 i7s should be able to run 3x2gb at 1066 (of approved memory chips) and still be with in voltage specifications. So any board should be able to do that with any 1366 i7. Though, the OPs problem is with the board not the CPU. Also it should be noted that the bios can have a effect on how well a rams memory chips will work and overclock (either speed or timings).
