My Video Card
Before we look at overclocking, I should point out what I am using, so you can compare results and see why your card has/has not got features mine does, especially with Anti-Aliasing and filtering methods.
The video card I own is a Hercules GeForce3 Ti200. The card is very close to the nVidia reference design, which isn't necessarily a bad thing, but does mean it's fairly feature thin. The stats of the card are:
Core: nVidia GeForce3 Ti200 Core, 0.15 micron, 175MHz
RAM: 4.0ns DDR SDRAM, 400MHz, 128-bit DDR
Bus: AGP 4x with Fast Writes
Cooling:Core - Half size Blue Orb
Memory - Blue Heatsinks
As you can see, the card is certainly a standard, non-variation version. One thing Hercules has opted for is non-stock cooling. They have added a half sized Blue Orb and some RAM sinks. The RAM sinks are more than likely Thermaltake ones, as they look exactly the same including color and the chipset cooler is a Thermaltake product, so the heatsinks probably are too. On my card I replaced the chipset cooler with a full sized Blue Orb, which will help to overclock the core slightly higher. I'll explain how to fit a new cooler a little later.
