well seems I'm running out of mobo. The MSI just isn't playing nice much above 305HTT for some reason. Lower cpu multi in bios isn't allowing higher HTT scaling. Even tried 2x HT multiplier. Oh well, might try this in a DFI board later to see if I can get higher . Would be sexy with some Mushkin UTT I have that goes 253MHz 1.5 -2-2-6 stable 24/7 and benches into the 260's .
