Hi everyone,
I have to upgrade my late 2011 15" i7 @ 2,4 Ghz MacBook Pro from 4 Gb to 16 Gb ram.
The site http://www.everymac.com/systems/app...4-15-late-2011-unibody-thunderbolt-specs.html reports its specs.
So I need 2 sticks of 8 Gb 1333 MHz PC3-10600 DDR3 SDRAM, SODIMM with 204 pins.
Now what I want to know is the supply voltage of the ram, 1,35 or 1,5?
From what I know DDR3 ram voltage is 1,5 V whereas 1,35 V is for DDR3L,
Crucial suggests 1,35 sticks ram

Kingston suggest 1,5 sticks ram

which one should I buy?

MacBook Pro, RAM upgrade

Both'll work, get whichever's cheaper.
 
Both will work. 1.35V RAM can also run at 1.5V, provided they conform to the industry standard.

You don't specifically need 1333MHz, though. You can choose 1600MHz instead, if you want.
