THANK YOU ASUS for this bios. fixes all my 1066mhz ram problems.

my crucial ballistix tracer 8500 2x1gb use to fail at stock settings with the 0502 and 0601 bios's. With the 0602 bios, i just completed 20passes of memtest finally.

i've noticed that with the 0502 and 0601 bioses, memtest reported a bandwidth of 5593mb/s at stock speed. The latest bios reports 4895mb/s. so i guess to increase stability, they reduced the speed a little.

finally i have a stable system with no random BSOD's from ram errors
