No idea if that's accurate but i use quad superpi/systool pi tests to test and for my QX9650 stability occurs at 1.28v VTT with 115/107/88 for quad pi tests. When it's unstable it just reboots at high fsb.
Thanks for the advice, I'll go try this. If I wanted to hit around say 475 FSB on 1:1, I'm guessing I'm going to need around 1.3, or will I need more? I'm right now OCCT'ing at 440 with 1.3VTT and values of 125/115/105. Also, should I just focus on ONE set at a time? Or do each affect the others values? Once again, thanks for the help eva
