Is it just me, or is "DRAM Command Rate" non-existent in the BIOS? (I'm on 0803 right now)

Also, where do you guys find beta BIOSes for this board?

P.S.: I did notice ASUS posted up a new BIOS on their site, 1003, but I saw many many people getting problems with it, so I did not flash it. I'm still on 0803.
