Perhaps run default clock, 133fsb but bench the memory @ 133 and >then at 100mhz. Might be interesting to see what happens. It would be less useful on our machines than on the Xeon systems. The 760MPX and 760MP chipsets don't add bandwidth with more processors as the Xeon chipsets do. It's been a long time since I peeked into my BIOS, but I believe I have FSB controls. I'll try to get at least 4 sets of results, 5 tests each with min/max/ave. No promise for this weekend, but definitely by next weekend. -Matt
