Need another 512MB stick of PC2100 DDR to bring my system to 1GB. Prefer Crucial or Kingston but will consider any brand that's reliable. Needs to be a single 512MB stick, not 2x256.

Let me know what you have and your asking price.

Crucial has 512MB PC2100 sticks for about $60 new right now. Might be easier to just buy new at that price.

I have a Kingston HyperX 512MB PC2100 I pulled from an upgrade. $45 shipped if you want it. Tested and working.
