Mac Pro - DDR800 instead of DDR667

[the_b_man]

I'm getting RAM for a Mac Pro (2x dual-core Xeon) that takes DDR667, but I can get a far better price on DDR800.

I've seen varying reports of success with this, but not a lot of decisive answers on this. With a non-Apple PC, you can use faster RAM at the lower clock-rate. Can I do the same with Apple, and buy the DDR800 and put it in with the 667 and have it work?

Thanks

i can't imagine why it wouldn't work, the ram should just clock down to the speed set in the EFI, and I've done it in my G4 Macbook Pro without an issue.

Should work fine.
