I’d like to know if there’re any side effects to these memory configurations for MacBook Pro mid 2012 (I guess this can be extended to any Macs with removable memory).
Doubt 1: any side effects if I use slower or faster memory?
Doubt 2: should I use different sized modules, such as a 4GB in one slot and a 2GB module in the other?.
Doubt 3: can I mix the speeds (such as 1 memory slower than the other).
Doubt 4: is dual channel used in the 2012 Macs? (I can’t see this stated in support.apple.com/specs)
