Monday, February 10th, 2014 Author: When using a new Mac Pro 2013, installing four matched memory modules will get you optimal performance. This allows the system to use quad-channel addressing, which is the most effective mode of operation.
That being said, in the real world – as with the 2009-2012 model Mac Pros which supported up to triple-channel addressing and even with the 2006-2008 models that REQUIRED matched pairs – more memory trumps multi-channel addressing where you have an application or applications running that make use of that memory. Here is an example of a “memory hungry” situation. We took a really large image file, in this case 40,000 pixels wide and 56GB in total size, and ran some scripted operations in Adobe Photoshop. Image used is 20,000 pixels across, and 15.7GB, X-axis is in seconds. You can see where increases in total memory become less significant above 16GB. Above 20GB, the biggest percentage improvement comes in going from 32GB as two 16GB DIMMs, to the same capacity but as four 8GB DIMMs for a 3.5% improvement.
That is the ideal configuration for these systems; four matched memory modules, which allows full quad-channel operation. Taking it one more step, we ran a speed test that allowed us to stay in the memory-footprint of the smallest shipping configuration of 12GB (3x4GB). 8GB speed test X-axis is in seconds Now all of the differences are driven by the mix of module sizes, which set the operating mode for the memory controller; dual-channel, triple-channel, or quad-channel. Again, the biggest difference is between the two 32 GB configurations where two 16GB modules underperform vs. Four 8GB modules by about 3.5%. So, there you have it. Where you have more memory than needed, the real-world impact of mixing and matching memory is pretty limited, topping out at a little less than 4%.
You can choose the right amount of memory for what you need to do, what you plan to do, and what best fits your budget. The 16GB modules deserve a bit of extra attention, as they are what are known as “Registered DIMMs” or “RDIMMs” for short and are incompatible with the standard 4GB and 8GB products, all of which can be freely intermixed.
Say that you have 12GB or 16GB now and want to go straight to 32GB. You can go with a 4x 8GB set or a 2x 16GB set. Knowing that you can’t mix 16GB modules with 8GB or 4GB, the benefit of going with 2 x 16GB is that later on you can add another 16GB stick to go to 48GB and another to go to 64GB – all without losing your prior investment. It’s a small price to pay in performance to maintain flexibility. Here’s the data from our testing. Digiloyd Photoshop Benchmark Data So, for best results, sets of four modules should certainly be utilized.
If, however, you’re on a budget, adding more memory will always provide the most significant performance bang for your dollar. Don’t be restricted to Apple’s limited memory upgrade options.:.

Recently I purchased and installed 2×32 OWC Ram in my Late 2013 Mac Pro. After removing the 4×4 Ram, I installed the new Ram modules in slot 1 & 2. After startup the computer showed the 64GB installed.
The next day when I checked again it only showed 32GB. So after removing and installing the modules in all slots I have determined that Slot 2 isn’t working. Any ideas if this a bad slot, or does it need cleaning, Firmware update? The slot and the computer looks very clean as I keep my studio as dust free as possible. Thanks for your help! Can i use memory out of my old 2009 “silver” mac pro in a new 2013 “trash can”.
My old “cheese grater” died (processor or power supply) I would like to use some of the memory in the new machine and buy more from owc. I’m wondering if you will take back in trade any memory I can’t use and for that matter would you be interested in buying my 2009 machine so you can refurb it. Thanks John Hobbs (Ps I guess what i’m asking is does the old silver mac pro and the new “trash can” model use the same memory. Thanks again. That is an excellent question. This boils down to whether your computer will take advantage of more than 64GB. If your computer and the applications you use it for will use the 96GB, then you will see a great difference, though it is difficult to say exactly how much faster it will be.
The 32GB modules are handled a little differently by the new MacPro and end up running at a slower rate. You can find details of this in the Important OWC Note on. Also, you have the multichannel effect in memory, so the more matched modules the faster it goes when using the same amount of memory.
All that together, it is best to make sure the computer will use more than 64GB or else it may actually go slower with the upgrade. It is worth checking into, though, as the upgrade is great when it benefits the system. Recent Posts. Macs last a long time.
