Yeah, I only managed about 610 with my MIIF (which I was so glad to be rid of). Didn't mess around for as long with 3 of the the EP45 range, but I was guessing there'd be no FSB records hit and could post around the same. I reckon my E6300 (old type) could have gone further, but it's long gone now, ran a 100% o/c stable on that with a P5B.
