The newer iMac G5 with the built in iSight camera runs 240pin DDR2 DIMMs. This machine has 512MB soldered on the logic board, and one memory slot. That memory slot can hold a maximum of a 2GB DIMM, for a system maximum of 2.5GB.
Stacked v. non-stacked chips:
A module built from stacked chips takes two RAM wafers and stacks them on top of each other. This makes it possible to build a large module (like a 1GB DIMM) using cheap low density parts. Stacked chip modules are bad because they draw more power, and have inflated error rates caused by heat build-up. Ramjet uses the highest quality non-stacked IC chips.
