Its an Asus P6T...it should support up to DDR3-2000.
I started messing around with some of the settings in bios -- adjusting based on the specs on OCZ's website. I haven't upped the voltage yet; its still around 1.5v.
I set the frequency to 1600mHz
timings to 8-8-8-24
Everything started up fine but the settings were the same when I looked at speccy or cpu-z.
