The boy sat Overclockers Club have a pretty good GPU lapping
guide up... We've been lapping GPU's for a while now. =)
Many of us in the overclocking community love to push every
little bit of power out of our components whenever possible. Whether its upgrading
equipment or improving on our existing hardware, many find themselves doing
hours of work for a small drop in temperature, a gain in clock speeds, or both
if possible. Lapping a heat sink is a common way to improve a system's cooling
factor, but what about the component the heat sink itself is trying to cool?
If that component isn't as flat as the heat sink, then there was probably little-to-no
gain in lapping the heat sink to that component. Today, we'll show you how to
lap your video card processor core.
