Hello everyone, sorry if I make mistakes, I'm french.
I have a Crosshair V Formula (bios 1301) and I try to overclock my X6 1055T to 4 GHz.
Currently I'm at 3.5 Ghz stable @1.325v.
I made several tests for one week ;
-I've started to find my max CPU with the other settings to minimum, so I found HTRef @305 , coef 10x.
-Then I've fixed 285x14 to obtain 3990 MHz always with other settings to minimum : it's stable at 285x14 @1.456v with the LLC in Extreme so it reaches a peak at 1.50v in Prime95 and OCCT. Max temperatures : CPU 59°C, cores 50°C.
-Currently I'm searching my max CPU/NB frequency :
Please find below my current bios settings (if you need pictures from Bios, tell me) :
Overclock mode : Manual, and no D.O.C.P.

Voltage HT du NB : 1.193 v
Voltage NB 1.8v : 1.85 v

DIGI+ VRM :
-CPU LLC : Extreme
-CPU Over-Current Protection : 130%

But with this settings, I cannot finish a Cinebench test, neither 10mn of OCCT.
Is one of my voltage to slow ?
