Where's the TNT2 OC Guide?
Isn't the TNT2 better?
We recommended the TNT2 over the Voodoo 3 in both our
Gaming PC on a Budget Guide, and our
Vanilla Video Card Buyer's Guide because the normal TNT2 is just as fast and offers more features than the Voodoo 3.
We didn't take overclocking into account because the TNT2 doesn't have an almost guaranteed overclocked speed. There are several TNT2 board manufacturers, and they all make different types of TNT2 cards with all sorts of different core and memory speeds. Considering that each card may even use different types of RAM, you just can't count on buying a card and expect it to be able to overclock up to ***MHz.
We were able to overclock our Hercules Ultra TNT2 (175/200) up to 190/200, and tests with three different Creative Labs Ultra TNT2 cards gave us three different limits: 155/185, 166/190, and 170/191. What does this tell us about the overclocking potential of various Ultra TNT2 cards? Not much at all, except for the fact that all the cards are capable of overclocking, but we already knew that. We just don't know how far a TNT2 will overclock. Three models of the same card reached three significantly different overclocked speeds. We need consistency.
Granted, the Ultra cards are already clocked a good amount past the standard 125/150 rate. Maybe most of the regular TNT2 cards can overclock up to 150/183.
What makes the Voodoo 3 different?
Finding the overclocking limits of the Voodoo 3 is a little easier because there's only one manufacturer, but overclocking is always a game of chance. The V3 yields may be fantastic and all the chips on the V3 2000 boards could easily make it onto the V3 3000 boards, or the yields could be average and the V3 2000 chips could be the ones that didn't make it into the 3000 bin.
Well, if all the online reports are true, it looks like the V3 2000 is a very overclockable card. The only restriction holding the card back might be the 7ns memory. Let's take a look at how far we were able to push our V3 2000.
