I've searched around, but unfortunately haven't found this information. Does anyone here know how well a Q9550 will overclock on a Gigabyte GA-EX38-DS4 motherboard. I'm not shooting for a fantastic overclock, but would like to hit 3.6+ GHz, which is basically 425MHz x 8.5, although I would prefer 450MHz x 8.5 = 3.825GHz. Also, should most DDR2-800MHz memory hit 900MHz, or am I better off with 1000MHz RAM? With DDR2 memory prices so low, I'm thinking of just getting 8GB RAM (4 x GB). Will that interfere with the overclock?
