MacPro1,1 using 800MHz ECC RAM?

[timidhermit]

Can my 2006 MacPro1,1 use 800MHz ECC DDR2 fully buffered DIMM RAM that normally are from a MacPro3,1? My stock MacPro1,1 uses 667MHz ECC DDR2 RAM. Can the higher RAM modules simply downclock to fit to my MacPro1,1?

Can't find any reliable information on clockspeed compatibility.

Lovely. What's that got to do with a Mac Pro using FB-DIMMS?

 

[thats all folks]

the RAM will work fine, and run at 667. go for it.
