I am using 1.5V RAM in the MBP 2012 13''. No problems.

Corsair Venegance CL9 PC3-12800 2x4GB

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...
