Gigabyte GV-N220OC-1GI (GeForce GT 220) vmods
Hi guys! Hope this thread will help somebody to mod his GT 220 for fun as I did -)
The card looks like this one:

Without cooling system, Vgpu & Vmem measuring caps shown with red lines:

Blue-coloured caps - low-voltage, red one filters 12 V line.
Vgpu=~1,03 V, Vmem=~1,5 V.
GPU voltage regulator is uP6205A (11 pin = FB, 8 pin = IMAX), Mem-line - uP6161S14 (4 pin = FB, 7 pin = GND). My mods are shown on the pic:

(I hope it's clear you have to solder new caps to the original caps pins or the nearby points (e.g. choke outs). Don't forget about the polarity!)
Please metion that OCP mod IS NOT TESTED WELL and I'm not sure about its necessity for the non-xtreme OC!
Remember you do all the mods at your own risk. Have fun!
