OK so I have been figuring out this whole OC thing. And unfortunatly I'm lost BIO's wise. However...my motherboard has OC genie ii and it over clocked it for me. My ram stock clock was 1333 now it's 2250. CPU was 3.4 and is now 3.85. I can attest that it made no difference in FPS what so ever so I'm going to assume that I would need another 570 sli'd to increase FPS stability. I do like that my core's are no longer peaking and very supprised to find that over clocking can be so stable.
Sorry I missed this but you may not want to run your RAM that high with Phenom II. If you post your mobo it'll be easy to see how to just up the multiplier. OC Genie OCs the BUS not the multiplier. That's why your RAM runs so high. But if it's stable, go for it.
