Pencil mod w/o multimeter for a beginner

post #1 of 5
Thread Starter 
Need some help guys. The screw up with my card is that voltage control via software is impossible due to limitations being custom-set on the card by XFX (yeah they suck). Thus it's impossible to get my card beyond 840Mhz on the core, which sucks because I really need to help rack up a few more points for team OCN on HWbot thumb.gif

I don't have a multimeter and i just want to know which resistor to shade and how much of it. It'd be a HUGE help if someone could just show me which point to shade (first time doing this and have NO knowledge). Also, i just want to increase the VDD and leave the Vmem alone.

Here's the PCB layout of my card:

Pencil mods are stupid and dangerous. Pencil mods were cool in the Pentium days, but this is 2012. Seriously, just learn to solder.

Doing a volt-mod without a multimeter is a bad idea. Just get a multimeter.

You never even mentioned what card your using.

If your not gonna solder or buy a multimeter, look into doing a software vmod. You change the I2C code that sets the limits on the voltage. It involves re-flashing your GPU.

If you tell me the card, agree to solder, and get a multi-meter, I'll help. Never done a volt-mod myself, but I'm a electronic engineer and can give you a hand with the technical aspects.

I'm using a 5750. Any idea on how to go about the software mod?

Hmmm..I having a hard time find info for how to do that for your particular card.

I did find one website, but it's in German. You can use google translate to translate the directions to english.
