This isn't a guaranteed working fix, but head on over to www.guru3d.com and look for their GeForce Tweak Utility. A lot of folks have had at least some degree of success with it when using older TNT cards.

There is a program called TNTclock just for the TNT look around on www.megagames.com may be they still have it or get Rivatuner i havent used it so i dont know if or howit works here is the link http://www.guru3d.com/rivatuner/

My TNT2-M64 plays quake just fine
but its still slow enough to where the O/C actually makes a difference
it gives me an extra resoloution to play at

How about upgrading to a 3dfx Voodoo5-5500 AGP? Then, you could even go to a higher resolution?:smokin:

Becuase a Voodoo5 SUCKS. Always has, always will.

If he really wants an upgrade he should look into a 50$ GF2 Ultra, Pro, or GTS.

I downloaded and played with just about every program for my tnt2 32mb vid card. Found riva tuner to best the best. Also while youre at 3d guru, get some det drivers, go for the 5 or up to 12 series, stay away from anything later as they are really for newer cards and windows xp. Have fun, with those 2 mods i got my tnt2 from 600-700 up tp 1030 3dmark2001se points (3dmark is another program you should get, it tests the card with some game scenes, so you can compare mods and test for stability)
remember, dont start cranking it up straight away, start off with a 10, 15, or 20 point increase, then work up with 5 percent increments, testing with 3dmark. bring it back down if you see anything funny happen on the tests. You will be able to get memory o/c greater then core, so if you get to the point where you have to drop the setting due to 3dmark crashing or showing weird stuff (look carefully) keep on raising the memory clock by very small increments: peace:
