it's not so much a dumb board as a really weird and puzzling board.
but not so weird and puzzling as blackops, thank god.
Visualist, basically the jist of the last 20 or so pages of this thread has been that 2x2gb modules are rarely able to operate at speeds of 1600mhz or above on this or any other P45 board because of inherent instabilities in the memory controller of the P45 chipset itself. Tony (the OCZ tech support guy who posted in this thread a lot) has tested and tested again 2x2gb modules on this and many other P45 boards and has concluded that your best bet is to drop your RAM speeds, tighten your timings, and be happy.

Now on the quad core overclocking side of things, i may be able to help you there. This board has been great to my Q9450, and I've been able to get it to 3.9ghz stable with 488fsb, and 4ghz benchable with 500fsb, and 4040mhz validate at 505fsb. This chipset seems to be a great option for quad OCing as it allows for higher fsb than many and seems to stay stable. Are you having problems OCing as well?
