I'VE FINALLY DONE IT!!

i7 920 @ 4600 (21x219) HT OFF 1.472v on air, no tricks and with case closed.

I guess i can lower the vcore, 1.472v was just to be sure it would be enough. The vcore reported easytune is wrong, eist is enabled so vcore is dynamic.

The trick? Look at the qpi pll voltage!

Wish i could try with HT ON but the temps rise too much.
