hm ok, heeeeeeeeeeeeeeeeeeeelp!!!

Who can help me?! I’ve got a few sets of Voodoo 2 boards. (2x STB BlackMagic 12mb [1998], 2x 3dfx V2 1000 ?mb [1999], 2x Diamond Monster 3D 2 12mb [1998], 2x Guillemot Maxi Gamer 2 8mb [1998]) The problem is that of one set the memory configuration isn’t exactly clear. Normally the 8-12mb versions are easy to discern from each other by checking the memory layout; the 8mb version only has memory chips on the front where the 12mb version has both sides covered. My two 3dfx Voodoo 2 boards, have according to the FastVoodoo2 4.6 driver (dxdiag), 12mb EDO each. But if I check the layout of the board I only find memory chips on the front and ‘placeholders’ on the back. The boards are both produced in 1999 by STB. My original 12mb STB BlackMagic’s are produced back in 1998 and both have 12 memory chips on each side; this comes at a total of 24 chips. Although the V2 1000 and BlackMagic boards are very similar (same factory), there is a difference in TMU and FBI revisions as well as in the memory chips used. On both boards the memory chips are from Texas Instruments and run at a speed of 100mhz, but they contain other numbers. The V2 1000 is the one with the newer chips. The STB BlackMagic’s definitely contains 12mb of EDO memory, but of the V2 1000 boards I really wouldn’t know…

Can someone help my out?

Thanks in advance!

Greetzz from The Netherlands!! :p

Both are genuine 3dfx V2 1000 boards REV C. (C)1999

To me it looks like both boards are 12MB each, just using different capacity chips than most models in that times - with "double-sided" V2s, there were either 4 (for 8MB versions) or 12 (for 12MB ones) additional chips on the back (1 chip = 512KB). For example i have a Powercolor V2 board based on the same design, 12MB VRAM. Didn't know that other brands were using it though.
