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.
I would recommend this item to a friend!
