I recently upgraded my 2.66GHz 4 core Mac Pro 2006 to a 2.66 GHz 8 core. I am using 667MHz DDR2 ECC fully-buffered RAM but I see that when new the 8 core model used 1066MHz DDR3 ECC SDRAM which is less expensive.

 

Is it advisable to install the faster memory, will I harm the machine by doing so? Is there any advantage other than cost because I still have the orignal motherboard so supect that the RAM will only operate at 667 MHz?
