Lapping delle sk video

I've done lapping here before, however recently I've been becoming tired with how much slower my secondary internet/lan rig seems to be getting in games. This system is maybe quite typical of many peoples computers, its a C366 @ 550, on a Soyo 7VCA with 128Mb of RAM and a V3 2000 overclocked to 170MHz. I wanted to give my machine a little more oomph without either having to upgrade to a Celeron 2 or getting a GeForce - both are too expensive. After my experiences pelterising a TnT2 I didn't really want to go to that much hassle again, I wanted a quick and simple way to get my V3 faster so I decided that since most video cards heatsinks are attached with crappy glue I'd start playing around with the V3's HS.

Before I go on I'd better warn you that doing this will void your warranty, however unless a store pops off the heatsink or you do a really messy job they probably wouldn't notice, however there is great potential for destroying your video card.

The first thing to do is to take the heatsink off. If you've never done this before it can be quite scarry, its also the bit where you'll have the most risk of destroying your card. You'll need a flat headed screw driver and some masking tape to do this. Firstly put masking tape all round the video chip, this is to ensure that if your screwdriver slips it might not scrape away a connection on the PCB. I tried to take a pic of this next stage but trying to hold a camera in one hand, a screw driver in the other and taking good quality pics is a no no. Basically what you do is put the flat head of the screw driver underneath the heatsink then twist or leaver it upwards. You may find that it helps if the heatsink is hot - and the glue therefore softer, either use you mums hairdryer or play a couple of rounds of Quake 3 before starting. It'll take some force but suddenly the heatsink will "pop" off, you may get an image something like this - as usual images are clickable for a bigger view.
