However, it appears to be too early for those folks to have tried it yet and see if doing so stands the test of time.Įven if the 2012 Macbook pro can use 1.5V memory, it doesn't save you that much money and the 1.35V parts use 40% less power which in a laptop is very beneficial especially if you're going to 8G or 16G parts. This is one of those situations where folks might experiment with certain brands of 1.5V memory and discover that it works in the 2012 MBP. So I'm guessing that means the 2012 Macbook pro provides a 1.35V power supply for the memory which would imply 1.5V (regular DDR3) will actually *not* work-or at least not reliably. The new Macbook pro is Ivy Bridge/22nm IC process node-same as DDR3L. The RAM spec sheet says it is 1.35V which is the new 22nm DDR3L format.ĭDR3L is required by the industry spec to work at 1.5V, so even if your computer was designed for DDR3 (any mac made before June, 2012), it would work with DDR3L too, but use more power assuming the 1600MHz parts work in 1333MHz machines (according to user testimonials at Newegg, they do work.) The RAM that OWC is selling works fine in the new (2012) Macbook Pro (I bought the 8G kit and installed it-no problems). I've done some more research since my original post.
