Hi guys.

I'm owning a Gigabyte 8I865PE775-G-RH rev 2.0 board.
trying to mod this board to rev 3.0-4.9 and i need to know a PWM controller model

Is there any happy owners of this board rev 3.0 or 4.9 ? Could you please check the PWM controller model (small IC between the LGA775 socket and memory slots)

It's ISL6312CRZ, I highly suggest to download these 2 schematics to understand the difference between VRD10.1 and VRD11.

thank you.

i already running c2d on this board with bios from rev 4.9

the only thing is the voltage settings not correct when i set the voltage from bios. i belive it is just different pwm chip
