Did you manage to do any higher than this yet? I was hoping this board has more in it, as I max out at around 542 FSB / 650 MHz on my P5Q-Deluxe.

Also regarding the max FSB of 571, managed to push this any higher?

After looking carefully at the BIOS options, I was wondering what the effect of altering the MCH Ref values is? I know with for example the Gigabyte UD3P the MCH Ref setting is critical to get high FSB. I assumed you tried playing with them, but if you didn't perhaps it may allow it to go a little higher. It'd be nice to see 580 - 600+ out of this board, as boards like the Rampage Formula can manage to do it.

Lastly, how hot does the digital PWM get? I've heard conflicting observations about digital PWM, some asy it runs cool, others say it runs very hot. Is the cooling for it sufficient?

There are quite a few permutations that can be derived from those four settings with all their options. I thought I found a DFI PDF that had suggested settings for certain DRAM chips or FSB settings but darned if I can find it. Getting this board to recover from a bad OC is a lot harder than the LT P35 where you just held down Reset and Power for 4 seconds.

I guess the other thing I wanted to know eva, is if you had any kind of system for testing the DRAM clock/driving options and skew models. There is scarce little documentation on what they actually do or even which levels are high and which are low.

Oh, and if you could share some of those BIOS settings for your high 2:3 memory clocks

Just another note, 3oh6 says Rampage Extreme uses the ICS 9LPRS919BKL clock gen, which is the same clock gen used on the P5Q-Deluxe, whereas eternal fantasy says its ICS 9LPRS918JKLF. Wonder who is right or if maybe both were used at different times/revisions.

Does increasing/altering the clock gen voltage and CPU clock amplitude affect/increase the max FSB achievable with the T2RSB Plus?
