Been reading thru this thread as I am planning a q9650 buy. Got a ep45-ud3p buying some g.skill 1100 now. I am just to about to page30 and am reading thoroughly trying to understand the oveclocking and the relationship of settings as they help or hinder sucess. My big question now is what batches have you seen that are most reponsive to overclocking. there seems also to be A B and C codes in the batch numer are they significant ? Meaning A's on average clock better Than B's ? Any help in this regard to help me try to get a good batch will be appreciated. thanks
