To raise the VMEM, you'd either pencil the VDD and VDDQ resistors or use 10K pots.

To raise the VGPU, you'd remove the Over-Current Protection resistors with a soldering iron and either pencil the resistor or use a 100k pot on it to allow even more voltage.

Well, at the forums at VR-Zone you may be able to find some completed pics..but my instructions and the site I gave you should suffice.

Penciling would be the easiest for a beginner.

Just pencil in a ] shape around the resistor and then keep measuring the VCOR or VMEM till a specific voltage is achieved. Keep in mind though, for the vcore you will have to remove those two resistors.

You can go the easy way and do a BIOS vmod for the GPU core. Use Nibitor (to edit existing videocard BIOS) and NVFlash (to flash the new BIOS onto card). Google it.

If you are going to solder, w/ you want a 10W soldering iron from radioshack and the lowest gauge solder you can find, preferably with flux in it.

You also want the sharpest tip you can find for the soldering iron. If you can find one, file the one you are given.

Make sure that when you solder, you don't let the tip stay on the resistor for more than 2 seconds. I usually use little "taps" till I get it right.

..for pansies..



The softmod will only let you raise your vgpu .1V and it won't let you alter your vmem.
