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.Customer Videos:
So after two years of music production and mixing... and I mean intensive work... I have only great things to say about this memory! just great! great price! great performance! (would have wrote much more, but I'm currently at the studio... so, you know... I'm busy)... :)
Highly recommended for everyone that seeking to upgrade his Mac Pro's memory!
Kind Regards, Radion.I would recommend this item to a friend!
As soon as I save up enough, I've got to get one of OWC's SSD's for my main drive!I would recommend this item to a friend!
OWC's kits are easy replacements for your hardware, no need to guess, pick and choose on other sites. That's quite a selling point in itself. RAM is an easy upgrade to do oneself (in these now aging machines) and one of the best ways to extend the life of a machine. If not in the market for a new computer this is the best thing to do with the one you have.
Thanks OWC.I would recommend this item to a friend!
