RAM that supports ddr3 and ddr2?

Hardware

In a recent score some of you might have seen in another post, I got an old hp workstation with some RAM that looks interesting.

This looks like it fits ddr3 and ddr2, am I correct?

It’s RDRAM, not the now standard SDRAM.

Essentially an expensive proprietary standard that died off in the early 2000’s.

EDIT: Is the only stick in the workstation, or are the other sticks the same? RDRAM died off well before X58 was a thing.

There are 4 sticks, 2gb per stick. Also that’s something cool to know.
