I cant seem to get 465fsb stable. All skews are on auto, 0802 bios. Any idea's?

Your problem is auto skews. They don't work properly like that, same with GTLs. Auto value on Clock Skews does nothing more than use base value, and if it doesn't then god knows how badly Asus AI functionality is setting them.

Auto is fine on voltages. But you can't just set Auto for settings which make or break stability at high FSB. They generally tend to break on auto

Try
CPU Clock Skew Delay 100PS
NB Clock Skew Normal
DRAM Clock Skew A & B start with Advance 100-150PS and slowly go towards Delay if possible. Delay gives higher memory bandwidth but also risks memory corruption if too much.
