I set my HTT up to 250mhz for my new ddr500 ram, then the multiplyer down to 8x so my proc. won't be oc. Then I reset a few times (bootvis) and next thing I know the multiplyer is back up to 10x and my proc. is running at 2.5ghz.
Good news is, runs insanely stable and only 4 deg C hotter than before, thanks to some awesome cooling with the arctic freezer 64pro and 2x areocool fans which push 89 cfm at just 43db! (or something like that, not sure about the db but it isn't loud to me)
