1600MHz RAM on a Late 2011 MacBook Pro?

While the 2011 MBP ships with 1333MHz RAM, some say that 1600MHz may not be supported in.

Others say that it is backwards compatible (going down to 1333MHz when installed).

But even some have suggested (and tried in a Mac mini; see last post) that the system profiler reports the full 1600MHz being accessible by the chipset.

Apple officially said that my MBP only supports up to 8GB, but this has been proven to be untrue. So could Apple be wrong about this? The i7 chipset might support 1600MHz.

If so, will 1600MHz increase performance?

MacBook Pro, Mac OS X (10.7.5)

Ram prices go up and down constantly, especially Ram for old Macs (17" models)

Implying exactly what I said, older Ram tends to be more expensive, 17" models are older models.

Go to the OWC or Crucial sites. They have the specs for which RAM will work with your computer.
