OWC Helps You Double Your 2008 Mac Pro Memory

Other World Computing announced today through its in-house MaxRAM® testing lab its Certified 800MHz PC6400 FB-DIMM Upgrade Kits for 2008 model (MacPro3,1), a known workhorse in the creative industry. OWC now provides up to 64GB — double the factory maximum installed memory — with up to a 48 percent lower cost. The 8GB per DIMM matched kits are fully tested and certified to meet, if not surpass, all Apple memory design and compatibility specifications and come backed by a Lifetime Replacement Warranty and easy-to-follow, step-by-step installation videos.

Maximum Memory Recommended for Optimum OS X and Application Performance

To get the full benefit of the Mac Pro, memory is critical. With applications such as Aperture, Creative Suite/Photoshop, iMovie/iDVD, Logic, Lightroom, where large files are being addressed, even 16GB of RAM is probably not enough memory. MacPerformanceGuide, a leading benchmarking source for professional photographers and Mac enthusiasts, found that 10-15GB of RAM is used just by their daily use of Photoshop. By increasing RAM, they found dramatic time reductions in working with huge files. With today’s higher resolution digital and video cameras, having the maximum amount of installable and addressable RAM is becoming a necessity for Mac Pro owners.


OWC MaxRAM Memory Upgrade Kits Offer Up to Double The Factory Maximum RAM:

Apple Mac Pro Quad-Core and 8-Core 2008 (MacPro3,1) ‘MaxRAM’ options now up to 64GB

• Matched Sets of 2GB Modules, install/add up to 16GB for as low as $26.25 per GB

• Matched Sets of 4GB Modules, install/add up to 32GB for as low as $31.19 per GB

• *NEW* Matched Sets of 8GB Modules, install/add up to 64GB for as low as $39.05 per GB

Original 32GB factory maximum. Apple no longer offers memory for this Apple Mac Pro Model.


Complete, matched set kits also available for all Mac Pro models: 

Apple Mac Pro Quad, 6-Core, 8-Core, 12-Core 2010-12 Models (MacPro5,1) ‘MaxRAM’ up to 128GB

• Matched Sets of 4GB, 8GB, and 16GB to install/add up to 128GB for as low as $9.22 per GB

Compared to current factory offered 2GB, 4GB, and 8GB modules costing $37.50 per GB, OWC kits offers up to 2X more memory and at a cost of up to 75 percent less compared to factory available.

Apple Mac Pro Quad-Core and 8-Core 2009 Models (MacPro4,1) ‘MaxRAM’ up to 96GB

• Matched Sets of 4GB, 8GB, and 16GB to install/add up to 96GB for as low as $9.07 per GB

• Matched Sets of 1GB, 2GB, and 4GB to install/add up to 32GB for as low as $20.63 per GB

Original 16GB factory maximum. Apple no longer offers memory for this Apple Mac Pro Model.


To assist all Mac Pro owners in selecting the correct memory upgrade for any of the 2006 to current Mac Pro models, OWC has created a simple to use guide that shows the correct memory type and options specific to each of the different Mac Pro models. The full OWC Memory line, as well as a compatibility guide which directs customers to the correct upgrades for nearly every Apple computer model manufactured over the past two decades, can be found in our online store.

“When you’re running professional A/V editing, graphics production and server applications on a Mac Pro, you can dramatically increase its performance capabilities by simply adding more RAM,” said Larry O’Connor, Founder and CEO, Other World Computing. “Even with the 2013 Mac Pros on the horizon, we will continue to work on Mac Pro upgrade options as these systems are far from done and often with much untapped potential. In addition to offering faster opens and saves of large files, general system responsiveness to operating tasks such as booting are greatly improved as well. Dollar for dollar, there’s no better upgrade than adding more RAM.”

Easily Improve Drive Performance Up to 5x

Mac Pro owners can take advantage of an available PCIe slot by installing the Mercury Accelsior PCIe SSD. Easy to install with no drivers required, this SSD offers speeds up to 688MB/s, over 2X faster data transfer rate performance than the maximum from an internal SATA connected drive. And, as the only Mac-bootable, Mac supported PCIe SSD available, Mac Pro owners can now also experience near instantaneous booting and application launches in addition to not having to wait for I/O-intensive apps like Photoshop, Final Cut Pro, or Avid Pro Tools to render, capture or process.

New Modern Video Cards/GPUs and USB 3.0 Connectivity

Unlike any other Mac that Apple has shipped in the last seven years, the Mac Pro’s internal PCIe slots enable a variety of upgrade options. In addition to the PCIe SSD for applications that depend on GPU performance, a selection of Video Cards specifically for the Mac Pro 2008 and later enable the necessary capabilities for a fraction of the cost of a new system. Capabilities such as USB 3.0 and mini-SAS are also just an upgrade away.

    • Nope, we’ve been offering and supporting the 8GB DIMMs since this press release. Looks like there was a coding glitch that caused the 8GB column to hide though…If you try the link again, you should see the full offering. :-)

  • Can you post benchmarks for the 2008 Mac Pro with 64GB RAM on the OWC memory performance page?

  • Correct me if I’m wrong, but all PC6400 (DDR2 800 MHz) FB-DIMMs that work in the Mac Pro 3,1 should also work in the Mac Pro 1,1/2,1 as well, just at lower clock speeds, yes? That being the case, the original Mac Pros would have the option of having 64 GB as well.

    • The MacPro1,1 and MacPro2,1 are unable to use more than 32GB of memory because they run a 32 bit EFI. We tested the 8gb modules in the MacPro1,1 and MacPro2,1 and the machines would not boot, so they remain maxed at 32GB.

      • I was under the impression that the 2007 macbook pro 2,1 can only address 3 GB of memory. What is the deal?


        • That is correct, the MacBookPro2,1 models are OWC tested to support 3.0GB maximum RAM. 4.0GB can be installed, but only 3.0GB will be addressed.

          However, this article and Ben’s subsequent comment is in reference to the Mac Pro, not the MacBook Pro, which can utilize substantially more RAM. :-)
