Jeez...yours is SB046X rev 2U PCB. I really don't know if that single bank that your card has, is 512 Mb (64 MB). Yours looks to be MT. Only three vendors sell memory banks to CT today: MT (Micron Technology), Samsung, Hynix Hyundai. If there's something that looks like a mt (greek "mu" t) it has to be Micron Tech. Send me its string (whatever is printed on the chip) and I'll tell you if its the expected 512 Mb. On the back side of the PCB do you notice an unoccupied memory bank place-holder above the batch info sticker? Yeah, add me as a member. I can solve problems as well. The PCB your card has is exotic for the North American region, it's made by Creative's Singapore homebase for the Koren, Aussie and Japanese markets. Wonder how it got there. Decades later you could put it up in your living-room in a laminated shelf as an awesome show-piece. I did that that to my 1996 Creative Ensoniq ES1730 PCI card (all Japanese/American components, 0% Taiwan).
