        Comments about Crucial 32GB Kit (2 x 16GB) DDR3-1866 ECC RDIMM Memory for Mac:

        Ordered two of these 32GB kits for my Mac Pro late 2013. Upgraded from the factory 16GB to 64GB. The 2 day delivery was shipped the day of my order and actually arrived one day early. Can't beat that. The installation -- about as easy as it gets. Even if you don't follow the memory replacement tutorial for the new Mac Pro, it's almost intuitive. No configuration needed after I powered back up...the memory went right to work and hasn't complained yet.

        I didn't notice this 32GB package of two chips and tried to order 4 of the 16GB individual chips. When that didn't work (my fault), I used the online chat and was quickly directed to this two chip package. Very quick and friendly service.

        I've used many Crucial products before, but this is the first time I order direct from their site. Fair price and very fast service.

        The only glitch I encountered is with a particularly temperamental software package I have that writes its own "system signature". Any changes to the computer configuration invalidates the activation code. Easy to delete the signature and re-enter the license code. No fault of the memory and not a really good way to implement a license. Just something to look out for after an upgrade if you own software like this.

        Comments about Crucial 32GB Kit (2 x 16GB) DDR3-1866 ECC RDIMM Memory for Mac:

        Works great, easy to install. Pricey but still much cheaper than ordering from Apple. Noticeable increase in performance when running multiple programs at once, or any large file video editing work.
