DDR ram in dual 867 question
I have ordered a new dual 867 (grrrr been waiting so long but that is another story). Can I put DDRPC2700 in it or will it only work with the 2100? And if it will work, would there be any advantages/disadvatages to doing so. My PC friend says that it is backwards compatible but I wanted to check and make sure. Also can I buy DDR ram that is made for PCs as long as the specs are the same? Is ram, just ram no matter what computer it goes in?
