Hey, I;ve searched a lot on this but don't seem to be getting any straight answers for myself so was hoping someone could iron out my queries. I've just ordered my Mac Pro (very excited) and intend on upgrading the RAM myself. OWC will cost too much with import tax, Crucial and Kingston seem costly too. Upon investigation, DDR3 1066Mhz Ram is not that common in terms of people that do it. It seems that Corsair, OCZ etc do good RAM, but is 1333Mhz and so not in Apples range as they are locked at 1066. These 1333 are the same price as 1066 or less sometimes. My question is: Even though they may remain locked at 1066, can I use 1333 in my Mac Pro? I intend to use Boot Camp for Windows 7 for gaming, so better RAM would improve that hopefully. I'm dropping an EVGA GTX 295 in too which should be pretty sweet Thank you.
