Good IOH chip can run over 240MHz with x36 QPI link speed.
Average IOH can run around 220 - 230MHz with x36 QPI link speed.
Bad IOH chip just only run under 210 MHz with x36 QPI link speed.

The first you check your IOH QPI limit.
You can check QPI link limit with x12 CPU multi, easilly.
(If x36 QPI link & slow mode limit are same, it's CPU BCLK limit.)
I'm limited to 215 before degradation kills my 3D scores and 220 before it stops booting... which is absolute bull crap considering how expensive this board is.

What kind of support does Asus have for extreme benchers? Can someone PM me a better way to go about getting this resolved (or a good contact) since on the front end "overclocking voids warranties"?
