As new video cards are being released, many users are feeling "left behind" in the market, and look at their recently purchased video card as if it they got it years ago. To keep up, many computer enthusiasts are discovering overclocking, and the benefits from it. Some add huge aluminum heatsinks and 1u copper coolers, while others go and watercool their video card. Some even go to the extreme of using sub-zero cooling to cool their card, whether it be using a T.E.C. (AKA peltier), a water chiller, or even custom mounting phase change systems meant for extreme CPU cooling onto their video cards. What do people do when an overclock becomes unstable?? They add more voltage! You see people adding more voltage to their CPU's and RAM, why not your video card? This guide will go through the steps taken, in giving your ATi 9800 series that extra boost it needs to run super overclocked speeds.

DISCLAIMER: Voltage modifications done to your card VOID your warranty, ATI will not honor any warranties for a modified video card. All modifications are done at your own risk! Neither myself, nor FastLaneHW.com will take any responsibility for the loss or destruction of your video card because you screwed up, by following the procedures written below. This guide assumes the reader has some before hand knowledge in overclocking, soldering, measuring voltages and resistance.
What you need:
15W or 25W soldering iron (any more is overkill, and is easier to kill a card because of the heat output),
22-28 gauge wire, along with solder and rosin,
(2) 10K Ω 0.75W 15-Turn PC-Mount Trimmer (available at Radioshack),
Voltmeter/Multimeter to measure the resistance and voltage
Thermal Sensor to measure temperature
Terms to know:
GPU = Graphics Processing Unit (you knew that)
MEM = Graphics card Memory
VGPU = GPU Voltage
VDD = Memory Voltage
GND (Ground) = COM, and/or black wires in power supply
