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.

Rating: 4/5 Oops! August 25, 2016 I have a Mac Pro and wanted to max out the system RAM in my computer. I had previously purchased it with 16GB of RAM in 4MB modules (an expensive proposition in 2009), which left four slots free for additional RAM.

OWC's RAM worked. But NOT with my existing RAM. I spoke with Jim and he walked me through everything step by step. He was very patient. First, he proved that OWC's RAM was not a problem. Then he tested to see if we could put the OWC RAM in different slots—did not work. Finally, he recommended that I match all of the RAM, which could only be done in one order. I am sending this RAM back. There is nothing wrong with it, save it won't work with my existing RAM. Kudos to your support team, I am buying the whole 32GB at the same time for my Mac Pro (4,1 early 2009, 8-Core 2.93 GHz Quad-Core Intel Xeon).

If you are looking for RAM that is guaranteed, period, go to OWC. If you are looking for great support, go to OWC. I might recommend that anyone with a workstation-class computer be informed that buying a complete kit all at once is the right way to add RAM.

Rating: 5/5 received and enjoying August 15, 2016 I got this relatively quickly. I've had no problems with the problem at all and there was ZERO problems. I'm very happy with service of MacSales. If you're unsure about buying parts, for anything mac related, pick MacSales before E-b-a-y or A-m-a-z-o-n. I'm sure the ram was just renamed by MacSales, however the ram was high quality and well-made.

Rating: 5/5 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.
