GTX285 various mods.. which may work for GTX260/280/295 also

[NapalmV5]

However I pencil the resistor with 2B, I can't reduce the resistance more than 600 ohm (stock was ~750ohm acc.to my DMM), I'm still on 1.22v, but this is better then 1.15v.

I'm quite certain Napalm used pencil as an experiment to identify the target resistor. Pencil mods are uncontrollable and not advisable. There is a hard mod you can do as shown, the solder point is as easy as it gets. Then you have total control.

If you absolutely must use a pencil instead, try one with a higher graphite content.

yeh dont use #2 HB for ex. no good

i used just a #2 and went over the resistor good.. no mercy

i got it as low as 320ohm

400-500ohm noticeable vcore increase


updated step #3
