And though Apple warns of "acoustic" issues with conventional spreaders, our Mac Pro's fans never kicked up during our testing of the Data Memory Systems samples. The samples from Data Memory Systems with conventional heat spreaders did average slightly warmer temperatures at the center of the heat spreader (near the Advanced Memory Buffer chip) but were far below the recommended maximum for that chip. And ALL samples averaged about one-half the 275F maximum recommended for the Advanced Memory Buffer (AMB) chip.Ģ.

As long as we kept the side panel attached to the Mac Pro and only took it off briefly to sample heat sink temperatures, ALL samples tested below the recommended 159F maximum for the memory chips. We ran this test for 10 minutes, sampling the temperatures on the left, right and center of the outermost heatsink on the top riser at the 9 minute mark.ġ. By running five copies of the app, we were able to stress a total of 15.5GB of memory. We used the DigLloyd Tools (dlt) "stress tests" which thrashes all four cores and exercises up to 3.2GB of memory (32 threads total, 95MB per thread). We also tested the two 512MB modules that Apple shipped with the Mac Pro from the factory. We tested 1GB and 2GB modules provided to us from Other World Computing, Trans International, MaxUpgrades, Data Memory Systems. We know you are spending good money for your Mac Pro memory so we want to be circumspect in our comments. Posting a temperature graph based on questionable data just to create an artificial "horse race" would be irresponsible. Then again, it could be argued that it's doing a worse job of dissipating heat. It could be argued that a hotter heat sink is doing a better job of absorbing heat. Measuring the same spot on each can be unfair and misleading.ĥ. Different heat sink designs absorb and dissipate heat in different ways. Ideally, a thermocouple should be attached to the actual memory chips - something we are ill equipped to do.Ĥ. The temperatures of the heat sink doesn't necessarily reflect how hot the memory chips might be. We're not convinced measuring temperatures with an infrared gun is the most accurate method.ģ. The temperatures varied by as much as 15 degrees on different runs.Ģ. We have decided NOT to publish them because.ġ. The whole thing should take less than five minutes.We agonized over whether to publish the temperatures we sampled from the heat sinks. All you have to do is pop open the access panel, remove the existing RAM modules, add your new modules, and then replace the panel.
You can see below that upgrading the RAM in a 27” iMac is a simple job.

And obviously, you won’t find guides for models that don’t let you upgrade the RAM. Each guide has links to all the components and tools you need to do the job. Head to iFixit and find the guides for your Mac model. They also sell all the tools and components you need to make the upgrade. They have detailed guides for replacing the RAM in any Mac where it is possible. Instead, I’m going to pass you over to our friends at iFixit who specialize in this sort of thing.
It’s far beyond the scope of this article to talk you through every possible Mac RAM upgrade. MacBook Pro 15” with Touch Bar (All Models).MacBook Pro 15” with Retina Display (All Models).MacBook Pro 13” with Touch Bar (All Models).MacBook Pro 13” with Retina Display (All Models).You currently cannot upgrade the RAM yourself in these Mac models: Unfortunately, in the last few years Apple has taken to soldering the RAM to the motherboard of the computer-particularly on laptops. As things stand now, you can upgrade the RAM yourself in the following Mac models: Other modelss, like the latest 21.5” iMac models, require you to remove the screen and logic board-a process that will take at least a few hours. When you know what model you have, you can find out whether you can upgrade the RAM yourself. I’ve got MacBook Pro (Retina, 15-inch, Mid 2015).
On the Overview tab, you’ll see your Mac’s exact model. To find out exactly what Mac you have, click the Apple logo in the top left corner of the menu bar, and then select the “About This Mac” command. A 21.5” iMac from 2012 and a 21.5” Retina iMac from 2016 might look the same at a casual glance, but they’re totally different computers.
Macs are regularly refreshed and even if newer models don’t look all that different, big changes can happen on the inside. If you’ve got an old Mac that’s out of warranty, you can take more risks than if you’re thinking about tearing open a brand new MacBook Pro. Adding more RAM can breath new life into an old Mac.Īs always, make sure you know what you’re doing before diving in. While Macs certainly aren’t as easy to upgrade as a typical PC, it’s surprisingly simple to upgrade some components like RAM-especially if you’ve got a Mac desktop or an older laptop.
