TnT2 Ultra should be about as fast as Geforce2MX 200 (the one with 64bit memory interface). It's quite a bit slower than regular MX (with 128bit SDRAM 166/175Mhz core/mem). Gefore256/2/3 with DDR memory are all WAY (times) faster than TnT2 Ultra on higher resolutions.
You probably have PC-100 SDRAM DIMM's, BX chipset doesn't support SIMM's and there ain't such thing as PC-100 SIMM...
