Need help identifying --Regular TNT2 or TNT2 M64?

Topic says it all. This is a Best Data TNT 2. Here's a link to the product specs.

Looks like a regular TNT2. The spec says the graphics controller is a TNT2. If it was a M64, it would say so. Spec also say the card has 128 bit architecture. The M64 is 64 bit architecture.

the very first thing you see when you boot your computer should be the video card BIOS. it will appear for about 2 seconds then your computers BIOS will boot. look and see if you see M64 anywhere on that and if not it is probably a regular TNT

The specifications say its a 128bit chip. All TNT2 chips have an internal 128bit datapath. The TNT2 M64 however has a 64bit memory bus as compared to 128bit for regular/Ultra TNT2s.
However, it does look like a regular TNT2 as there's no mention of M64 anywhere.

Thanks Goi. Wasn't sure how some models list both 128 bit and M64 in their literature on tnt2's.

No problem. A lot of people get confused with the internal datapath bus and the external memory bus of chips, especially the G400 with its 256bit internal dualbus...adds even more confusion.
