Last night, after some pressure from a friend I finally started to OC since getting my board back from RMA (was a bit nervous, yes).

BIOS: 0901
CPU: Q9450
RAM: G.Skill DDR3-1600 2x2GB

Hit 1600 Linked and Sync'd (7-7-7-20, 2T, 1.9V) with ease (had corruption and memory errors prior to RMA)
Hit 1700 Linked and Sync'd (7-7-7-20, 2T, 1.9V), again very easy
Hit 1800 Linked and Sync'd (7-7-7-20, 2T, 1.9V)

Memory Timings and Memory Voltage were the only things modified, everything else was on Auto. Started the easy way...

1800+ is where problems started to happen and I was too tired to keep going. I'll post up BIOS settings tonight for some help from you all, but what worries me is the result after going above 1800. Going back to stock timings I could not boot into Windows, got the blinking cursor after POST and no amount of tweaking would boot into Windows.

Like I said, will post BIOS settings and some SS's of my results tonight, but just wanted to see if anyone had this happen.
