I have run my Q6600 to 4200 Mhz 466 Fsb on my Commando Motherboard.. http://valid.x86-secret.com/show_oc?id=195644
My Memory is Gskill green heatspreader BNR version...

and it Holds Great under duel orthos although i notice no matter what i do in the bios after 10 min or so it seems to throttle back the multiplyer..

i dont know why and im not sure if its Cpu related or motherboard related...

i cant see me ditching this board in a hurry as i know its so solid..I have killed a few p5b-delux mboards trying to get where i am today with the commando..

i do run a pencil vdroop on the motherboard as it helps my Oc greatly.
Cheers Hori
