Rating: 5/5 Make a monster out of your older Mac Pro March 31, 2017 Upgraded 2012 Mac Pro 12 Core to 128gb core memory for heavy editing with Final Cut Pro. What an improvement in performance. This 5 year old machine still outperforms most new computers on the market today. This upgrade along with a Nvidia Titan X with 12 gb ram video card cuts movie processing time down significantly.

Rating: 5/5 OWC Mac Memory - outstanding! December 20, 2016 I purchased a new dual 6-core Mac Pro computer in mid-2012. from Apple ...the last of its kind. I immediately upgraded the memory to 48 GB. Recently, I upgraded again with OWC and purchased 5 more of these 16-GB memory modules to max-out my Mac Pro to 128 GB of RAM. Wow! It flies through processor/memory-intensive programs like nothing I have ever seen. OWC stands behind their products and I trust them implicitly. This memory is designed and manufactured to the strict Apple/Mac standards and works perfectly.

Rating: 5/5 MacBook Pro memory at Max July 24, 2016 When I ordered my new MacBook Pro from Apple, I planned on immediately pulling the memory and putting in the maximum it would hold. This is the best cost-effective approach. I also pulled the 500 gig. HD and replaced it with a 1 TB making my MacBook Pro ready for editing high definition video. Very satisfied with the approach I took. You can learn how to do it I watching the videos on the OWC website.

Reviewer: Anonymous Location: Paris, France

Rating: 5/5 Good priduct and exceptionnally good customer service March 30, 2016 My experience was buying this 24Gb RAM ugrade for my MP 5,1 6-core 3,33Ghz, which I had been looking forward for a long time (also highly upgraded the GPU last month). The product is as mentioned, was installed and works like a charm (although I believe I was already confortable with 12Gb of RAM, I noticed some RAM page outs lately using Photoshop CS 6 / Capture One / Firefox). Now what happened is that the package got stolen in my mailbox and that it was difficult for either service (OWC/Macsales and the French postal service) to assume responsability for this theft. Nevertheless, having proven my honesty in this situation, Macsales took it to them to send me another pack, at the one and only condition I accept DHL (and the customs fee, about 1/3 of the total price in the end, but still worth it). I must pay total respect to the quality of the customer service here which helped me from A to Z. Cheers ! And to those that order from EU for example, I strongly recommend using the trackable and person to person delivery exclusively. Too much theft in mailboxes in Paris these days !

Rating: 5/5 Extremely competent customer service and superb product March 29, 2016 Prior to purchasing, I had a live chat with a very competent service person who guided me through the intricacies of RAM selection for my MacPro 2010.

I wanted to max out the RAM and the advice I received helped me a lot to secure the correct memory reference for purchase.

Shipping to Europe was a mere matter of days and the RAM worked out of the box providing the announced performance.

I'm very satisfied with both the product and overall purchasing experience.

Definitely recommended to european customer who want competent input prior to issuing an order.

Reviewer: Anonymous Location: fdog Owned Product: 1-3 months

Rating: 4/5 A bit slower than I thought it would be November 12, 2015 But that could just be due to more memory being handled by my early 2009 Mac Pro than prior to switching to this.

Upgraded its single 2.66 GHz 4-core cpu to 3.46 GHz 6-core processor, and figured I'd take advantage of opportunity to use faster (1333MHz vs 1066Mhz it came with) memory allowed with the firmware update that basically turned the Mac Pro into the equivalent of a Mid 2010 model.

But nothing really changed, maybe just a teeny bit slower with the memory benchmarks. So either more memory made the small anticipated performance bump a wash, or perhaps the firmware update doesn't really take advantage of the faster memory speed after all with my hardware.

Regardless, if nothing else I now have more than twice the amount of memory I had before. The CPU bump has definitely perked things up, GUI behavior nice and smooth with Yosemite, though slightly better graphics card may also be helping with that. (Prior to all this, the early 2009 configuration I had was a bit sluggish overall and hesitated a bit here and there prior to doing some GUI activities. But no longer the case, mostly... getting Excel 2011 to do anything faster is apparently just never gonna happen.)
