[QUOTE="The_Pro, post: 1129949, member: 152493"] Sup guys, I have noticed that the new 11.6" MacBook Air only has a 800 MHz frontside bus!!! However it used 1066 MHz RAM. just wondering if apple screwed up on this one!! As as far as I know if you install 1333 MHz RAM in MacBook Pros which have a 1066 MHz frontside Bus then the RAM wont be able to run at 1333 but be used at 1066 MHz. This isnt something which is stated in system profiler or smthin so dont bother answering, but is says its 1333!! :P it can only run it at the speed of the frontside bus. Well okay wait, 1333 MHz RAM does improve performance over 1066 in MBP's but not to the extent they would if the frontside bus were 1333 aswell. So you see, if apple has a C2D chip with 800 MHz frontside bus in the 11.6" model, the RAM wouldn't perform the same way it does in the 13.3" with 1066 MHz frontside bus. Im not exactly sure but as far as i know that would be the case. Glad if you techies could gimme some knowledge on this Cheers [/QUOTE]
