Overclock on P5G41-M LX

[Alex5800]

Hi, I have this motherboard and a Pentium Dual Core E6500 2.9 GHz, i can overclock it to 3.7 GHz without Vcore, but if I go over, the pc is going to crash and on the BIOS I don't found the Vcore option, can be the BIOS unlocked?

Nothing hidden to unlock but you already have lots of overclocking options under "Jumperfree Configuration"

if you cant see these options try pressing ctrl f1 , ctrl f9 , ctrl home or ctrl insert while in the bios. These key combinations sometimes unlock advanced settings
