yea I had some stability issues at 1560 and above, and couldnt post anywhere near 1600, so I think ill stick at 1550 for the time being. I've been running some occt tests to get it stable and havent really had issues yet so I may be at 2.9ghz for awhile unless I get the itch to push it higher. It seems some guys have been pushing the voltages pretty high but dunno if I wanna risk it. I found a huge thread about this mobo too. Thanks bman!
