    How can I tell if 1600 MHz RAM is XMP or not?

    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.

    Does anyone know about this Corsair Vengeance 1600 MHz RAM: Newegg.com - CORSAIR Vengeance 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model CMSX16GX3M2A1600C10
    Is it XMP or non-XMP?

    Do you mean the Corsair Vengeance will run at 1600 MHz in my MacBook Pro? People say it needs non-XMP memory. I looked at your link, and it sounds like it is non-XMP memory, based on these things:

    "If your notebook is equipped with a 2nd Generation Intel® Core™ i5 or Core i7 processor, it will automatically detect the faster speed supported by the Vengeance laptop memory upgrade kit. No BIOS adjustments are necessary to take advantage of the faster memory speed."

    "Auto-overclocking (no bios configuration required)"
