as you know, most high end cards used vram so that reading and writing do not get in each other's way and provide sufficient pixel bandwidth for high resolution modes, while dram are usually used by low end cards.
for example, the s3 trio64v2, one of the fastest 2d cards(without 3d features), can only support up to 1024*768 in highcolor and 800*600 in truecolor, which seems pretty low.

therefore i wonder if there are exceptions that can support high resolution and color depth, with following requirements:
1. the card must be using conventional dram(including fp and edo), no vram, wram, sgram, mdram, rdram or other special types of ram.
2a. the card has 32bit ram width, can support 1024*768 in highcolor and 800*600 in truecolor, non-interlaced.
2b. the card has 64bit ram width, can support 1280*1024 in highcolor and 1024*768 in truecolor, non-interlaced.
