Rating: 5/5 excellent so far May 3, 2015 I upgraded the memory in my dual-six Mac Pro and have had no problems with the memory for a couple of months now. Using all banks is supposed to be slightly slower than sets of three, but I have not noticed that. What I have noticed is that it is faster now that I can have more disk cache.

I would recommend this item to a friend!

Rating: 5/5 Excellent! March 20, 2015 Rather than buy a new computer I decided to upgrade the $#%t out of my 2010 Mac Pro. It worked. The thing sings now with all this RAM. I also put in a SSD boot drive.
