Good info Emu. This helps quantify the effect of QPI. When I raised QPI on my 860, I knew it was faster but not how much since we were using the old test method.

Question, I notice CPUz reports what I'm assuming is idle volts at 1.117? Did you get that clock with a LOT lower voltage this time? If so, WOW!

Good to hear you got them to exchange your old board.
