The RAM it takes is 66MHz SDRAM, 168-pin / 3.3v. There may only be one slot, if that model has onboard SDRAM. The other small slot (the brown one) is for COAST memory (cache).

Please hold on the purchases.

Details about your computer please. CPU and some photos of interior especially motherboard.

This will help us.

Cheers,

What I'm seeing everywhere is 16MB "fixed" and one slot for up to 32MB, 48MB Max... but when I find a motherboard picture it looks like 2 SDRAM slots. So it could mayyyybe take two 32MB modules, but maybe won't support more than one bank on the first slot or something.

Looks like it could be either of these..?

Is this your mother board? Looks like a VX chipset, which is limited to 128 megabytes maximum. A 64 megabyte DIMM ought to work, giving a total of 80 - I saw an ad for one of these for sale with 80 megs of RAM installed. This does exceed the cacheable RAM limit of 64 megabytes with the VX, so 48 megabytes may be the better choice.

Thanks for the help everyone!

I was looking at the `COAST Memory`. My floppy drive was covering where the SDRAM goes. I put it in and worked perfectly. Thanks for the images of the motherboard that made me realize my mistake instantly 🙁

I put in 128MB (was the cheapest I could find on eBay). The BIOS/Windows shows 48MB just as expected. Machine is perfect for playing Blood/Duke 3D at full settings, I also added a Trio64V2.

I might put a 233 MX in it for fun. A little worried about cooling, might not be worth it? At most I want to play some RTSes (Starcraft, AoE)
