help OC with C5F and 1055T

[fr4n5oi]

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) :

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

Increase your voltage on the CPU but make sure your temps are still manageable.

Or you have reached the limit of your quest.

hello HiVizMan,

I've fixed my VCore to 1.462v (1.51v in burn) and it seems to be stable.
I've done 10mn of Prime95 just for test and my temperatures don't increase up to 59°C.
What do you think about it ?
