Picked up this video card - model KY2-JAX-SVGA805. It looks like I could add a couple of chips to it but have no idea what to look for or where to get them. Suggestions? Here's some pics:

Thanks, people.

I do have a PCI card with what appear to be identical sockets (4 of them, each with a chip). I was thinking of putting them in. What's the worst that could happen? No boot? Spontaneous combustion?

I have the exact same card and successfully upgraded it with standard 256K x 16 bits EDO DRAM chips.

Cool. Found some on ebay that I hope will do the trick.

They are just SOJ chips. with 70ns of access time..

The memory chips are only to can use a lot higher resolution.. because it can adress more with more memory on this board.

The card wouldnt get faster..

~ At least it can do black and white~

Actually each of those chips has a 16-bit interface. When used in pairs, they allow the resulting 1 MB of RAM to be addressed by a 32-bit width bus. If you add another pair of chips, the resulting 2 MB may be addressed by a faster 64-bit width bus if the graphics card was designed to support it. That's how S3 Trio64 and other similar cards work when you install the memory upgrade.

Good info. I'll run a benchmark before and after to see how it turns out.

OK, but that info is true for 64-bit cards only. IIRC, S3 805 is a 32-bit card.

Some ET4000 chips can do an interleave like that as well.
