My system:
Mobo: Asus P5QC
CPU: Q9550
RAM: 2x2GB Corsair XMS2 DDR2 1066
PSU: Bequiet SP7 450
HDD: 1 SSD, 2 7200 RPM, 1 5400RPM
VGA: Geforce GTX750Ti KalmX
If I leave the bios on its default settings, RAM works ok but only at 800. If I manually set frequency at 1066, timings and voltage suggested by the manufacturer (5.5.5.15, 2.1V), my system works too but at boot it restarts once. Turns on, turns off and then restarts.
I previously had an E7500 CPU which I've replaced with the Q9550 and the manual settings for the RAM worked perfectly with that.
Anybody could help? Thanks.
EDIT: I forgot to mention: this only happens if the computer is left off power for some time. If I boot then restart or if I shut down but leave the computer plugged and re-boot, this doesn't happen.

RAM ratio of 1:2; now with the Q9550, same manual BIOS settings, it's 5:8.
