Theres a bug with this board in the way it handles dual channel and adjusts TRD. Gigabyte is working on it, and should release a working BIOS as soon as its sorted out. Until then, run your ram in dual channel below 950mhz, or in single channel at higher speeds. In most cases, you'll get the best performance with tight timings and below 950mhz anyway, so..

Most ddr8500 memory should do just fine on this board at 2.3v 950mhz 4-4-4-4 timings. Adjust up to 4-4-4-7 if unstable. Make sure TRD is 8 or above no matter what. Also, Use standard or turbo on the performance enhance setting,- extreme is unstable in most cases in dual channel mode.

Most of us are having trouble making this board run stable at ddr8500 with just optimized defaults, just because of this bug. Just reset bios and boot with a single stick so you can set TRD to 8 manually. After that youll be set...

Ive also noticed unstability when upping FSB and MCH voltages. The board seems stable at default values up to 475mhz, so no need to touch'em anyway unless your multiplier is below 8.

for 950mhz 4-4-4-8 you only need 2.1v -2.2v max and 2.2 can get you to 1040 easy i wouldnt do 2.3v 24/7 on a gigabyte board unless i needed to
i lost 6 gigs @ 2.26v
with 2.26v i did 5-4-4-9@ 1150 on the dq6
