This morning swapped my 2012 11.6" air for a 2012 13.3" pro. Question though... Swapped my SSD from my faulty macbook with the HDD all working fine. But want up the ram from 2x2GB to maybe 2x4GB In machine is DDR3 12800. I looked up specs on everymac.com and it says DDR3L is needed but it does not have L ram in it now. Other sites also conflicting, can someone please confirm?
