    I just upgraded a 2012 MBP with it. Works fine.

    Good memory, BUT it's 1.5v vs. the 1.35v that the 2012s CAN take. 1.35v = Less power & heat, but it could be a minimal benefit.

    I bought 2x8GB of that RAM for a 2012 MBP. Works great.

    Yes I read somewhere that this might be an issue? I don't know about .15v but I searched everywhere and this is the closest to stock I've seen.

    The RAM works great, I have 2 sticks of it in my MacBook Pro and it has run beautifully.

    Ivy Bridge can handle either 1.35 or 1.5V, despite whatever Apple says. The reason the Retina uses 1.35V may be for the heat issues in the small case.

    There is no performance or compatibility issue with 1.5V.

    1.35V sticks are significantly more expensive.

    Never said there was a performance hit OR compatibility issue. However, there MAY be some reduction in heat and a modicum of power savings to the battery. How much is unknown at this point. Also, it's not just Retina that uses 1.35v. My 2012 cMBP came with 1.35v sticks.

    memory

    i know this is off topic but considering all the posts on ram, and i will be trying to update my ram in my old dell (old c2d) and the ram to match is for 8gb is around $140, is it because its the only compatible ram that makes it more expensive? older?

    retina macbook is so fast by the way! :cool:

    Yes, I just wanted to make it clear. There are several threads out there suggesting issues with 1.5V, and a lot of misinformation / confusion.

    It appears that all the 2012s come with 1.35V memory. From a practical standpoint, one won't notice any RAM heating except with intense use, in which case the processor heat will well overshadow any incremental RAM heat. Battery life ditto.

    In other words, it shouldn't make any noticeable difference for the uMBP. The smaller RMBP has the potential for worse heat issues, although its cooling system is actually more advanced than the uMBP's.

    i purchased 2x8 gb ram. installed it in a mid 2012 MBP 13 inch. System appeared to be OK unitl I ran memtest86. It failed the test everytime after about 5-7 minutes. I noticed my unit got very warm. I returned the memory and purchased the OCW RAM 2x8 1.35 and no problems whatsoever. Maybe my MBP's heat threshold was less than others reporting their experience with the Corsair Vengeance RAM.
