I've been reading the reviews here for some time now but this my first post. First a run down of the R7 260X's VRM layout.





Now lets get modding



Here you have the important controller pinouts. For the FB Vcore a 22K ohm variable resistor from the pin to GND will get you a starting voltage of about 1.3V under load. For the FB aux a 22K ohm variable resistor from the pin to GND will give 1.05V under load. Cut the pins or the traces connected to the pins labeled ILIM to disable over current protection for that VRM. So if you cut ILIM AUX the AUX VRM from the first picture will no longer have a power limit.



The VRAM voltage controller is a super simple controller and does not have over current protection. All you need to do to get it under manual control is to hook it up to a 220K ohm variable resistor to get a starting voltage of about 1.585V-1.6V regardless of load. I would like to thank techpowerup.com for allowing anyone to use their PCB pics.

EDIT: the forum formatting on here is painful

Hi man, thanks for coming and posting!


p.s why is so bad? :p

For about 20 minutes I couldn't figure out how to get the images in between the text.

Also I switched site themes and now my post is misformatted again. I give up
