AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[SergeantNathan]

I've already read tons of reviews on the Crosshair IV, so I was about to pass this by, but I thought I would take a look at their overclock:

I was always curious how some were able to exceed 300fsb, beyond just luck. Well, I found my answer: "CPU VDDA voltage", or, on other boards, CPU PLL voltage. I generally leave PLL voltages alone, but it looks like this particular setting helps with high FSB overclocks (also see their MSI results: http://hardocp.com/article/2010/07/2...board_review/1, again, higher CPU PLL voltage)

Even with my posted stable settings, I found myself sometimes being booted to desktop after long gaming sessions... lowering the FSB one notch sorted that out. After bumping the CPU PLL up one notch to 2.54, it looks like I can go back to my initial "untested" settings of 289fsb... I just past a 50-run on IntelBurnTest this afternoon. I'll do a 400-run tonight to confirm and update this post.

***Update***

Bah. 289 didn't pass overnight testing. Even 288. Back to 287. Looks like my RAM is at it's limit. Dropping timings and clockspeed down and upping CPU PLL to 2.7 for a max-fsb-test got me to almost 300, but it would not perform as well as my highly optimized timings. So, I'll stick with what I got.
