So far my results:

I have had ZERO issues with my RAID and SATA setup.

1.5 in BIOS reports 1.4ish with ASUS Probe under ORTHOS.

NB sink gets too hot for my tastes, I put A5 on it and a 120 mm fan on it.

Im at 1500 FSB and 850 RAM so far, but havent really messed with it THAT much.

So far Im pretty happy with it for the price I paid.
