Okay, just tested 415 x 9 with tRD 10 and the OCZ ram, started up IBT and after 30 sec it suddenly restarted (same problem i got before).

Next i'm going to try other ram (G.SKill PC6400), and if that's no go, i go for Ket's bios.

About the LLC, i have it enabled, got me 1.4000 in bios, gives me 1.376 idle and 1.4000 load in windows.

With other words, what i set in the bios, i get in windows under load. But what's the problem with LLC ?
I mean, if i disable it, and i set 1.4000 in bios, i maybe only get 1.376 idle but a lousy 1.328 load... Why not enable i then ? Gives it extra instability ?
