What type of memory (1.35 or 1.5V) does Macbook pro mid 2012 have?

Question

macbook

Good afternoon!
I plan to increase the RAM macbook pro md102 (i7 / 8Gb 1600MHz) id2012 to 16Gb, I began to choose and was faced with the fact that there are two types of memory DDR3 (1.5V) and DDR3L (1.35V).
On the apple website, I could not find information about what type of memory is still used. On the forums they write that they put 1333MHz 16GB, but this memory does not fit in frequency.
I would not want to buy memory, and then rent it out, because. does not fit. Moreover, the memory is sold in a sealed package.
Who increased the memory in md101 / md102, please tell me, what is the voltage of the memory you bought?

Answer 1

You can open your laptop and see what you are using there (you still need to open it anyway). DDR3L works well at 1.5V, so it doesn't matter. You can also supply 1333MHz modules. They will just work a little slower than 1600 MHz (in synthetic tests).
And what's the problem with buying DDR3 1600MHz and not fooling yourself? Any store is full of it. If in doubt, just select specific models and read the reviews at least on Amazon.
