Memory upgrade: 1.5V instead of 1.35V possible?

Is it possible to use 1.5V DDR3 instead of 1.35?

There are lots of cool DDR3 1600MHZ CL9 SODIMM's available at my location but not any DDR3L :(

Answered! View the answer I have this problem too

Is this a good question?

strange -- my 2012 13" MB Pro came with 1.5V memory from Apple..... I upgraded it with 8gb of the same type of memory (1.5V). No problems.

Hi, like senthor I ordered also the Corsair Vengeance Kit with the CL9 Timing.

Is there now any new information about the usage of 1,5V RAM?

All the 1,35V RAM modules I found have a CL11 Timing...
