This should be your machine:

Apple iMac G5/2.1 20-Inch (iSight) Specs

Identifiers: iSight - MA064LL/A - PowerMac12,1 - A1145 - 2082

RAM Type: PC2-4200 DDR2 Min. RAM Speed: 533 MHz

Details: Supports 533 MHz PC2-4200 DDR2 SDRAM.

Standard RAM: 512 MB Maximum RAM: 2.5 GB

Motherboard RAM: 512 MB RAM Slots: 1

So just add one PC2-4200 DDR stick in the lot.
