P55A-UD3 Huge vcore Drops

[sotiris]

Even though i have Load Line Calibration enabled when i overclock my vcore instead of going highter on full load it drops and makes the system unstable. All my friends that have this board they dont have this problem.
Me and my best friend bought the exact same systems and i overclocked his without a problem.
When in full load his vcore goes up and keeps his system stable. Mine has the opposite effect.
After 40 seconds on full load the vcore goes from 1.360v to 1.240v and system reboots. I have all the energy options disabled.
C-states disabled,Turbo disabled, HEIST disabled, LLC Enabled. Do you think theres a bios update that you can send me to fix that or should i RMA the board?

Or if its something else please tell me cause i'm going crazy.

thanks for the reply. I do have the latest F5 but i did the update through @bios. Does it matter?

Also does anyone have the same combination as me to help me with this issue? i5-750 + GA-P55A-UD3

Just Loaded Optimized Defaults and rebooting. If it doesn't work i will try to clear the cmos and get back to you.
