These OWC memory modules fully meet/exceed Apple's Mac Pro Quad & 8-Core Xeon model memory specifications. Utilization of qualified Apple Mac Pro Heat-Spreaders, Apple Qualified IDT AMBs, and the best major brand memory components ensure maximum performance and trouble-free operation. Modules are fully tested prior to shipment.

Apple specifically designed the Mac Pro with more space between each slot to accommodate the Apple Proprietary Heat-Spreader for thermal requirements. Use of Apple's spreader solution and the highest grade, thermally tolerant components ensure that these Mac Pro Quad Xeon Memory Upgrade Kits will provide a lifetime of reliable and trouble-free operation.

Apple notes that using parts with a non-Apple standard heat-spreader and which only meet JEDEC standard specifications can result in higher fan speeds due to increased internal temperatures and system controlled reduction of memory performance to prevent thermal overload. OWC's testing has found that use of non Apple qualified spec modules leads to ECC errors and ultimate system lock ups as non-spec modules reach significantly higher temperatures.

Two well known memory manufacturers originally listed their own JEDEC standard modules as being Mac Pro compatible. Within days of doing so, each removed this compatibility support after reports and testing which made clear JEDEC standard modules were not reliable in the Mac Pro. It is very disappointing that many other memory providers continue to list and misrepresent such JEDEC modules (lacking the proper heat-spreader) as being correct for the Mac Pro.

The Apple Mac Pro is an amazing machine. Memory from OWC only makes it better!

Rating: 5/5 Start up in 21 seconds March 28, 2017 Good old fashioned customer service all the way. Product is excellent as was the sales knowledge and compatibility with my TEN YEAR OLD MacPro 2, 1 - that the all knowing, (all knowing what - how to SELL MORE AND MORE) Apple ceased to support several years ago. OWC know more about Apple products than the GREEDY Apple. Thank you OWC There is life in my old Wee Beastie yet. Can't believe how fast it starts up since I added the SSD - 21 seconds is sooooo fast for a ten year old MacPro.

Rating: 5/5 First Class Customer Advice May 18, 2016 I recently acquired an original Mac Pro tower dating to 2006 as a gift. Supposedly OS X Lion was the end of the line for this model. However I found some online sources stating that with a bit of hacking, this Mac Pro could run the latest OS X version, El Capitan. Check if you're interested in finding out how to do this. There were some prerequisites however: Increasing RAM from the 1GB minimum that originally came with this computer. And upgrading the graphics card from 256MB to at least 512MB.

I initially thought 8GB of RAM should be sufficient and so started looking for RAM source. OWC/MacSales had an excellent web site for determining the kind of RAM necessary. Their's was one of the few web sites that explained that this Mac Pro required RAM with massive heat sinks to prevent overheating due to the architecture of the RAM cards. So I ordered the 4x2GB modules for $99 that was quickly shipped. Installed and along with the 3GB that came with the machine gave me a total of 11GB. This worked perfectly with OS X 10.7.5.

Further research revealed that due to some technical aspects of this computer being made to mod the computer to run the latest OS X, 10.10.3, a minimum of 12GB of RAM was needed and that the original 512MB RAM modules would not work. Armed with the knowledge about the necessary heat sinks, I was able to find 2x4GB RAM on eBay for only $32, a much better bargain and increasing memory to a total of 16GB.

As long as I was going this far to upgrade the computer, I bought a 512MB Nvidia graphics card (GT8800) on eBay for $85 and a 120GB SSD to use as a boot drive. The computer already had a 320GB SATA boot drive, a 500GB scratch drive and 500GB RAID. So I replaced the 320GB rotational boot drive with the 120GB SSD from OWC/MacSales. Hacked the boot.efi with information found on the Mac Pro 2006 forum on and installed the latest El Capitan OS on the SSD.

So now I have a blazingly fast Mac Pro running El Capitan that can drive two high resolution monitors and has lots of storage space for video and photo editing. There are a few features of the latest OS that still won't work because of hardware limitation (Handoff and AirDrop for example), but that's not a problem for what I'm using it for.

So although the prices for memory may not be the best you can find, the technical information you can find on OWC/MacSales site is invaluable as well as their being an excellent source for specialized tools for upgrading your hardware.

Rating: 5/5 New RAM for my Mac Pro October 26, 2011 My Mac Pro started acting funny, and the RAM modules exhibited ECC errors. OWC comes across as completely trustworthy, so here I came and placed an order. And it just works.

Rating: 5/5 Excellent memory upgrade choice May 27, 2011 We needed to upgrade memory on an early Mac Pro, and were pleased to be able to figure out exactly what modules we needed to order by using the model & configuration guide on the website. I liked it even better than the well-known manufacturer's memory configurators, because it's Apple-specific and gives the additional details about small differences between models. I was able to determine with certainty what to order, and had the peace of mind of knowing that all of Apple's recommendations were followed. The iTunes videos are another great touch, because you don't have to guess if you're correctly following the steps on a website, you get to watch the tech in the video perform the work and you know exactly how it's supposed to come apart and go back together. I previously purchased a hard drive upgrade for my MacBook Pro (early non-unibody) from OWC, and was so impressed with the experience that I didn't consider shopping anywhere else. Plus, the prices are comparable to other sites that don't have nearly the level of resources for the customer.
