RAM upgrade from 1066 to 1333 MHz
I own a MacBook Pro 13' 2011 and my wife has a MacBook 13' Unibody late 2008. I recently upgraded the RAM of my MBP from 4GB to 8GB, but my wife only has 2GB in her MB.
The RAM of the MacBook is : 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
The one of my MacBook Pro is : 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
My question is, can I put my old 2x2GB 1333MHz in her 1066MHz RAM slots without any problem ? Will it work ?
