Very technical question regarding VID mod to video card

[DopplersEffect]

Hello everyone.

I am doing the VGPU (Vcore) VID mod to my X850 video card:

http://www.techpowerup.com/articles/overclocking/voltmods/112/3

My video card has a VID table arrangement of 01100, this gives the card a voltage of 1.4 V. If I increase the voltage the only VID mod increase I can take the card to is at least 1.6V, unsafe.

SSSoooo, I was going to alter my VID table position be popping off one of the resistors on my VID arrangement, resistor on VID1 for instance. This would reduce my operating voltage; but, from the articles advice, when I use a conductive pen to short another "open" resistor, it will bring my operating voltage up to 1.5V like I want

My question is this: has anyone tried this? what were the results? Does the conductive pen work and last? where can I find conductive pens?

Thanks in advance for any help!!

conductive pens work great, pencil may not work.

depending on your type of conductive pen you may be able to rub it off with A LOT of effort.. try it on some other pcb first. make sure not to draw over open pads with the pen

find a conductive pen as rear window defogger repair kit for cars or as conductive pen in electronics

so the conductive pen works good and lasts, thats encouraging.

Has anyone gone to the extreme of popping off a resistor in hopes of getting a good VID mod??

yep, it's not very difficult. You can twist them off with pliers, or if you want to be more careful, grip it with the pliers, and heat the resistor with a soldiering iron.
