Does this mean DX actually can support SGRAM memory? Does that then mean the GX and the DX have no difference?

I don't know about differences, but here are S3 ViRGE DX and GX with 4MB SGRAM.
Take a closer look at ram modules. Jaton card has 10ns ram = SGRAM, Powercolor card has... 35ns ram = EDO in different package 😀 The only virge that can have 8mb ram is VX. DX can be faster because chip frequency is equal to the memory frequency. GX cards should have 75MHz ram, STB version with EDO is 75/75. Compaq card with SGRAM has slower chip but memory = 75MHz
The markings look really faint IRL, but in the picture they are clearer and you are correct, these are speeds for EDO RAM. Which reminds me, I have another GX somewhere with the same RAM packaging and I always thought it was SGRAM, too.
So, I think I have three S3 cards with similar PCB designs as pictured above: Two with EDO RAM, a GX and a DX, and another GX with SGRAM - which is considered better for S3D games?
