I have upgraded my 2011 MacBook Pro RAM from a Samsung 2x2GB DDR3 1333MHZ  (4GB) to 2x4GB Corsair DDR3 1066MHZ CL7 (8GB) (Print on the front - DDR3 8GB MACMEMORY compatible to Apple iMac, MacBook and MacBook Pro - 2x4GB).  Its running well, better than that, it's running great, however my question is that  will this cause my RAM to overheat because it's at 1066MHZ while the system is designed for 1333MHZ?  Don't know much about RAM. Thanks
