hmm great ! Then u've a very good CPU Quality.. i've not .. :p

For me default vbbx is 0xdb .. so 300mV ... it can run max stable @ 1150Mhz with 0x37 and 0x8F .. but very rare weird errors on kmsg during playing games.. but never an reboot.. so i decided to use go down to 1100Mhz with same voltages, and everything is fine.

Record on Codina is 1300Mhz stable.. but very rare ....

But i still don't trust the AVS File ... because they show different Values on Stock GB + JB !! So WTF ??

As for vbbx Values...

take a look here:

Table of non repeated Vbbx values:
