Can we put PC1066 RDRAM into a mobo that supports only PC800/600?

[CrazyCompGeek]

I have a mobo P4T long time ago. It's kinda slow now. I want to upgrade the RAM. But the mobo only supports PC800/600. Can I add 2 PC1066 into those slots with my current PC800? Are they compatible and work together?
TIA

Yes, no problem.

ram tends to be backwards compatible with slower speeds... unless there were revisions to the ram such as different number of pins, etcetera, should be backwards compatible
