OWC is proud to offer the best possible Mac Pro Memory solutions available.
Premium Quality Modules fully Mac Pro Qualified and backed by OWC Memory Lifetime Limited Warranty including Advanced Replacement Program.
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!

Reasonably priced, easy to install
August 30, 2019
Needed more RAM for my graphics programs and upgrading to El Capitan on my old Early 2008 Mac Pro. Didn’t realize I had only 3GB RAM originally installed when I bought the machine. Perfect time to add a new hard drive and install more RAM! Easy to install. Love that the web site tells you what is compatible for each specific computer model.

Good quality and reliable.
October 31, 2018
I had the stock 4 X 1Gb sticks in my 2008 Mac Pro 3,1 for YEARS, no issues. Until last month. Then one of the DIMMs went wonky on me. No surges or dips, no recent moves, it just went south. The machine would try to boot, then conk out before login. Took me a while to diagnose the problem, since the old RAM passed the POST. It just wouldn't boot El Capitan, even though Mavericks would boot on another drive.
These 2 X 8Gb sticks looked OEM, had the heavy-duty heat sinks, and now the machine is fine again -- even snappier in responsiveness (which I guess is to be expected since it's using NO swap now).

October 21, 2018
Thank you very much OWC, we live in Australia and the RAM was received promptly after ordering it. We installed the new 8 GB modules and we now have 64 GB of RAM on our 2008 Mac Pro.

Quick & sure solution for failed memory
June 30, 2017
Recently 24/32 GB of my MacPro 3,1 failed. I immediately ordered a full set of 32GB memory and MacScale promptly delivered the new functional memory to me and relieve my worry that the remaining 8GB may die any time making my workhorse Mac down completely. My Mac is now running fine and speed resumed. I would recommend this item to a friend! This review is from 32.0GB Mac Pro Memory Matched Pair (8x 4GB) PC6400 DDR2 ECC 800MHz 240 Pin FB-DIMM Modules.

Mac Pro 2008 new life

Cheapest, easiest upgrade possible.
June 14, 2016
Absolutely the best investment you can make for a slow computer is a memory upgrade. It can seem scary, but MacSales and Apple make it easy. First, Apple KNEW you'd want to do it. So they put the memory slots on nice slide-out boards which are easy to access. Second, MacSales provides easy access to the information on what your particular model needs. All you need supply is a tiny bit of time, and a little courage (Yes, the inside of your magic machine can be scary.) Seriously, this is a blue chip investment in your computer.

Should have purchased the full 32GB
November 27, 2015
My MacPro (Early 2008) had 4x2GB modules giving me 8GB. I was running out of memory for some of my music apps. I had read about heating and fan issues with a fully loaded MP as old as mine. So I opted for upgrading with 4x4GB FD-DIMMS figuring I could always get rid of the older 8GB I had. I now have 24GB and I haven't noticed any thermal changes at all with my system. I'm sure it runs a little hotter, but I haven't noticed fans kicking in. The setup really rocks now should extend the life of my MP another couple of years. Having the extra 16GB now allows me to load a huge amount of samples into RAM. I had to really go out of my way to start swapping to HD with 24GB. That being said I will probably get rid of the 4x2GB modules at some point and put in a full 32GB seeing that heat isn't going going to be an issue. (MacPro Early 2008 MacPro3,1, 2x2.8GHz Quad-Core Xeon, 24GB 800MHz FB-DIMM, 512GB PCI SSD, 4x3TB 7200RPM WD3000) I would recommend this item to a friend!

I had been meaning to upgrade my RAM for years. I wish I hadn't waited so long – although the prices I'm sure are better now than they would have been a few years back. Now my Old MacPro hums along the way it always should have. I've also purchased a number of OWC drives over the last 20 years and they all keep churning along. I'm a devoted OWC shopper.

Memory upgrade
June 8, 2014
I recently completed my transition to the max 32GB ram on my Mac with more of the "OWC Matched Set (4GB x 2) PC6400 DDR2 ECC 800MHz 240 Pin FB-DIMM Modules". The price had dropped a little since my original purchase. I am really pleased with my transactions with OWC. The orders have been handled and shipped quickly and efficiently. All of my old NON-OWC ram failed, fortunately not all at the same time, but the the original first 1GB upgrades of OWC have been completely reliable. I will continue to source and recommend OWC to all my Mac friends. I would recommend this item to a friend!

Nice boost to the system but OWC's after Sales care Rocks!
December 29, 2013
What impressed me just as much as the added processing speed I now have after adding 8 GB of RAM is the after market technical help at OWC. I was forced to call tech support as the configurations I tried from watching all available videos were just not allowing the RAM to show up as being present. The tech rep was patient, knowledgeable and stayed on the phone with me until the task was complete and he was satisfied that I was up and running as I should be.Apparently the 2008 Mac Pro has idiosyncrasies in the way the memory is accepted in the 2 tiers. Make sure you check with a tech when you purchase so they can send you a schematic for the proper installation which will vary as you mix and match chip sets and sizes of chips. Regardless, the professional, friendly tech support just further reminded me of why I prefer OWC for my Mac needs. Another satisfying experience from OWC! Thanks!

OWC is a TRUSTWORTHY and RELIABLE Reseller!
December 20, 2012
—You may save a few bucks buying from Silicon Valley,… but, I've NEVER gotten any ‘BUM CHIPS’ from these guys--their Lifetime Warranty is Platinum-Gold! —I use a Mac Pro, which distributes heat very efficiently; but, unless you work in an air conditioned environment, there's NO need to let these modules go over 145º. A Temperature Monitor and Fan Control software are a VERY WISE complement and popularly recommended to prevent overheating and extend the duty cycle of these sticks, especially on hot summer days without your air on. These modules are STURDY--but what's the sense in ‘melting’ GOOD silicon--unless… you're a GLASS-BLOWER! (-: I would recommend this item to a friend!

mac pro memory upgrade
September 21, 2012
Installed the macpro memory without difficulty. You need to install it in pairs as specified in the apple and OWC websites. I installed the largest sticks in the A1,2 slots and the remaining 4 x 1GB sticks were moved to A 3,4 and B 1,2 slots. No problem for the MacPro to recognize the memory.
