maybe its the bus speed, try changing it to another speed eg. 66mhz or 100mhz

Try another video card.
That one can't handle the increased speed.

Your problem is heat.  Either your TNT or your CPU is overheating.  I have a machine with same config at 463 2.2V with Spectra 2500.  Run flawlessly even with Unreal.

Solutions:

1)  What CPU temp are you getting after the crash?  (get a temp probe to measure if you don't have 1, you can pick 1 up from Radio Shack)  If you're getting anything over 43C that's no good.  More often CPU will work flawlessly at most apps but crash during intensive 3D because of heat.  Add a bigger heatsink and fan or build yourself a Celery Sandwich if you have to.  Details here:

2)  if your CPU after crash is well under 43C then your CPU might not have enough voltage, try uping it to 2.1 or 2.2V

3)  Your CL TNT is overheating.  CL TNT can overheat even if it's not o/c try adding a fan on top of the heatsink.

4)  Make sure your AGP is set to 2/3 in Bios...

5)  Made sure that your AGP Aperture size is not larger than your system memory size.


If any of this work, please reject the answer and let me repost as an answer.

Opps...  Mistaken you've a CL TNT, but anyhow, if your TNT doesn't have a fan on top of the heatsink, add one!
