I'm still on the 1.3 BIOS. I brought the mem divider down to 140 last night, chip to 2772mhz (9x308), 1.6v, RAM 216mhz @ 2.5-3-3-8-1T and it Prime'd Large FFT (extra heat) test all night fine, with the room A/C off. Not bad on stock HSF, no reapplication of thermal compound..
I'd keep her slightly slower at 9x306 (1.55v) with the 150 divider, but the RAM @229 wasn't quite happy >30mins on the Prime Blend test, no matter what vdimm voltage I tried. I'm sure if I slowed down the timings (2T maybe) it would prime, but I'm fine with "settling" with 2772mhz and tight-timed 215 RAM.
Doobie: Use slots 1&2 for dual channel (one purple slot, one green slot, the two closest to the CPU)
Solarius: Depends on how high your RAM can handle. 10x240 might not be possible 1:1 unless you have high end RAM. So just use a divider. Follow
