Anyone got some suggestions on values to start with on a Q6600 G0?

It boots on 400*9 atm with voltages as, but crashes prime within a few seconds. I know the cpu can deal with 400*9 as I've had it on another motherboard before.

CPU : 1.45
DDR : 1.9
CPU VTT : 1.23
MCH : 1.29
ICH : 1.09
ICHIO : 1.55
CPU REF : 67%

It'd be fun to push it further than that as well of course
