I have a 2011 MacBook Pro with a 2.4 GHz i7-2760QM CPU. The Intel website says the 2760QM CPU supports DDR3-1600 RAM. But looking on a Mac-related forum, people are saying you have to make sure to get the non-XMP version of 1600 MHz RAM or else it will run at 1333 MHz because the MacBook Pro doesn't let you go into the BIOS to change settings. They said that Kingston had XMP and non-XMP versions of 1600 MHz RAM and you could tell them apart by the model number.
No, that RAM is XMP, I have it in my laptop and it only runs at 1333 (since I cannot access XMP with my BIOS). CPUz verified it. http://valid.canardpc.com/cache/banner/2595895.png and no, dont ask me why I have 10GB of RAM with only 1 8GB stick installed.
