Can I use 1333 MHz RAM in a 1067 MHz MacBook Pro?

Mid 2010 MBPs (7,1) with Geforce 320M are known for freezing when using faster ram. Motherboard chipset supports it, but graphics chip doesn't and OSX freezes when initializes the graphics.

My recommendation - buy 1066MHz DDR3. If you can't find it in your local store, try OWC, it's a reputable online store that guarantees compatible ram at good prices.

ps. I'm not in any way connected with OWC.


i just tried to put into my Mac Mini 2010 which normally swallows 1033Mhz DDR3 ram modules 1333mhz modules of my newer late 2011 MBP and it happens as mentioned above, kernel panic, Mac won't start up. Don't do it! ;)


To support the point by @mspasov (sorry for unable to add comments), my MacBook Pro mid 2010 13" (MacBookPro7,1) did not support Hynix 4GB PC3-12800 DDR3 1600 MHz sticks if used alone or 4GB+4GB, they work only if coupled (2GB+4GB) with pre-installed 2GB 1033 MHz sticks from Samsung.
