2.9GHz on stock voltage
3.4GHz @ 1.55vcore
It popped with 1.49CPU VTT, I am at work, will have batch/week for you later
.002Vdroop on RD600 boards.... DFI FTW!
I took it to 350x9 on ~1.45vcore with a sufficient amount of tweaking then ran into a hard wall at 355. I pushed through it tweaking the FSB IO strength, GTL Ref voltage and CPU VTT and got it stable at 375, almost got 380 then it popped due to 1.49CPU VTT. The exact vcore stable @ 375 was 1.4v * 110.65%.
Memory is irrelevant on a RD600 due to fully independent clocking.
Load was 56c supposedly, but it may have been misreported... stupid E4300.
