July 28, 2019
Order arrived home on last Thursday July 25. Installed yesterday evening July 27 upgrading original 2 X 2 Go. Works great the first time. Tried to load the RAM with many apps at the same time and it just ran fantastic. Tks for a nice product.

Works great for Mac Pro Six Core Mid-2010 Westmere
October 4, 2018
I bought a matched set (2x8GB) for my Mac Pro Mid 2010 3.46 GHz 6 Six Core Westmere. I've had the RAM now for more than a year with no issues. I have a total of 20GBs RAM, with 2x2GB in the other 2 slots.
I tried to find information on the maximum RAM for this Mac Pro model, and it's a little confusing. It's either 32GB or 48GB?

From 8 to 32BG
September 4, 2017
I boosted my older 2009 Mac Pro from 8 to 32 with these 4 sticks. A local store said I couldn't do that but it worked just fine. I had to upgrade because I had added a second monitor to my system and it was pulling too much memory and causing slow web loading. Easy peasy to install. I would recommend this item to a friend!

Superfast 64 GB RAM upgrade
June 6, 2017
Superfast 64 GB RAM upgrade on a Mac Pro 4,1 tower. Fast delivery, great price, like new machine handles video even better now. User error on install (RAM was not firmly seated correctly by me) and MacSales talked me through it. Highly recommended!
THANKS!

Always Dependable
June 4, 2017
A client has an older Mac Pro quad-core tower server working flawlessly since new. I upgraded the RAM to the max of 16, up from the 6GB it shipped with. Also replaced the enterprise drives with SSDs. In a FileMaker server role, it is spectacular, serving up 8 million records. OWC always comes through. Been doing business with them forever. This review is from 4.0GB DDR3 ECC PC8500 1066MHz SDRAM ECC for Mac Pro & Xserve 'Nehalem' models.

Super easy to install and now the old Mac is snappy again!
November 23, 2016
These memory sticks woke my mid-2010 Mac Pro up from sleepy town. For six years I put up with the stock 6GB of RAM and finally made the jump to light speed! I'm an audio professional and am impressed with what a difference this upgrade has made. Don't wait as long as I did. You won't regret it. I would recommend this item to a friend!
