Smooth Upgrade - One Catch
December 12, 2018
Order shipped fast and was correct. One catch is these 16GB modules can not be mixed with disparate size modules so I couldn't use existing RAM. My bad as it was listed on the site but I did not see it the first time around. Machine wouldn't boot. I removed the 4x2GB DIMM's and everything worked fine. Live and learn. Also want to Thank OWC for great customer service. When I came back to see what the issue may be with my system I noticed a $30 drop in the memory I had purchased. I called the next day and they price adjusted my order no questrions asked. Am writing this review while returning for another purchase. Highly recommended. I would recommend this item to a friend!

Gave my 2010 Mac Pro a new lease on life
May 21, 2018
My original 10GB of memory was fine for several years but with the onset of processing large files such as RAW images, my beloved mid-2010 Mac Pro had been suffering. The OS X Memory Cleaner app had been indicating up to 99% of used memory and the machine was crawling.
The installation of 32GB of OWC memory speeded up operation of my computer remarkably and Memory Cleaner now usually shows only 30-40% used memory.
I've been a happy OWC customer since 2006 and I'm thinking that my next purchase is likely to be an additional 32GB of memory.
Thanks for the new lease on life, OWC!

January 4, 2018
My mid-2010 8-core Mac Pro is an audio / video production tool so the 12Gb of RAM it came with were bottlenecking the speed of some tasks. Ordering 64 Gb from OWC was the best decision ever ! The whole experience from ordering to delivery and installing was flawless !
I now have a brand new computer, unexpected for a 7 year-old computer.

Excellent RAM product at a very affordable price
December 16, 2017
I have been using this RAM upgrade for over a month in my 2010-vintage Mac Pro, both under macOS 10.12.6 and Win 7. I have experienced no problems whatsoever. In short, this a no-hassle, quality RAM upgrade at a modest, very affordable price. I wholeheartedly recommend the product to all whose "cheese grater" Mac Pro keeps running strong and can benefit from more RAM. I would recommend this item to a friend!

Works like a charm
July 16, 2017
I probably got more RAM than I will ever need, but then we always say that and then want more a few years later as technology advances. in any event this really sped up my aging Mac Pro for loading and multitasking. I was a little incredulous that it would make this much difference in an old machine - but it i did. I have not had this installed long, so I cannot comment on the durability of this product.

Excellent upgrade
May 7, 2016
Some perspective: in 1995, I was thrilled when my overlords at work allowed me to upgrade from a IIci to a PowerMac 7500 with a whopping 48 MB of RAM. The two additional 16MB DIMMs added about $1100 to the cost of the 7500. For about a fourth of that amount, I now have 48GB (!!) installed in my 2010 Mac Pro.
I had originally planned to go from my previous 24GB to 32GB either by adding another 8GB DIMM or replacing the current 8GB DIMMs with a pair of 16GB DIMMs; after deciding on the latter approach, I decided to avoid the possible pitfalls of trying to add a 16GB DIMM at some point in the future that might not match a pair of 16GB DIMMs purchased now. It's overkill for some of what I do, but it makes a big difference if you want to run Virtual Machines. Allocating 8GB to my current VMs has produced a noticeable improvement in performance.

RAM upgrade
February 12, 2016
After talking with representative of MacSales.Com was able to upgrade my MacPro with the correct amount RAM. He walked me through the process. The delivery came immediately and was easy to install. And, it has made my Photoshop workflow possible. Before the upgrade my Photoshop would crash if I opened any large photo to work on. I recommend MacSales.Com to anyone who owns a Mac (of any kind) and needs parts. Great company, great service. I would recommend this item to a friend!

It works
February 27, 2014
Installation was explained well and the chips seem to do just what is expected from them (for more than 1 year now). MacPro is running most of the time and sometimes under heavy load. I would recommend this item to a friend!

Mac Pro 2.66 Ghz Quad-Core Intel Xeon
January 12, 2012
I had 3gb (3x1gb) on Mac Pro 2.66Ghz Quad-Core Intel Xeon (Nehalem) Now i get just one of this 8Gb and on Geekbench it makes less score but is more faster working. Don't care about Geekbench, because is more faster now with 1x8Gb. I notice more quickly working with all program's! Even the temperature of the CPU is lower! (less temperature = less rpm + less noise = durability) great's from Portugal! I would recommend this item to a friend!
