    Hi all,
    I am about to upgrade my mbp-11 with 2x8 gb-ram.
    My preferred RAM would be the cosair venegance, 1600 mhz (70usd). They run at 1.5v and my question is if this is a problem.

    Will it produce more heat than these here at 1.35v?

    They cost a bit more (97usd), but I also prefer Cosair in the first place.

    So: Can anyone clarify if there is any real life difference here?

    Thanks
    Morten

    The 1.5v RAM may run a little hotter, but I doubt it would be anything you'd notice.

    I'd also look at other brands. Corsair is good, but there are a few bad reviews for the Vengeance stuff from Mac owners. g.skill actually makes good memory and I've used it in a few Macs. Crucial is good as well. Just read through the reviews on newegg and look for what other Mac owners are reporting.

    Neither company manufactures memory chips. I doubt either spec would be problematic, but test the ram when it arrives. Bad sticks are not that uncommon, and they will compromise your computing experience.

    OK,
    so I went to a store and picked up the Cosair Vengance.
    And - wow it flies. 16 gb ram - lots of green space in the activity monitor.

    If any of you have a slow MPB with too few RAM resulting in GBs of swap-files, then go for some extra RAM.

    They have fallen in price.

    The next thing will be a SSD-disk, but they have to be reduced to the half price as well - will happen within a year, I think.

    256 is already under $200 I don't see it halving again.

    512 at 200, now that will be a deal to remember.

    This isn't accurate in regard to Crucial, which is the consumer products branch of Micron. Micron is a major memory chip maker, and also manufactures NAND flash memory for SSDs with its partner, Intel. Micron's end user RAM modules and SSDs are fabricated and marketed by its "Crucial" subsidiary.

    Crucial wasn't mentioned. The OP mentioned Corsair and OWC.
