I have a couple of 2019 Mac Pros, and I’ve been experimenting with 2400T 32GB memory modules. Interestingly, I’ve encountered mixed results; some Mac Pros accept the modules while others do not. To ensure compatibility, I made certain that the modules were identical and avoided mixing LRDIMMs with RDIMMs.
This inconsistency raises questions about possible variations in motherboard revisions. I’ve observed that Mac Pros featuring an Apple serial number printed on the motherboard tend to accept the memory modules, whereas those without the serial number do not. This leads me to wonder if there are specific revisions or changes in the motherboard design that influence whether the memory modules will work.
It’s frustrating when hardware doesn’t behave as expected, especially when the components appear to be suitable. I’m eager to understand if there are underlying factors that could be causing this disparity in compatibility among the Mac Pros. Given that the models are from the same year, it seems peculiar that there are such differences.
Could it be something as simple as a manufacturing batch variation, or is it linked to firmware updates that might affect memory compatibility? I would appreciate any insight or information on this issue, as it would greatly assist in optimizing my setup with the appropriate memory modules. Understanding the compatibility landscape for these specifications could help avoid future mishaps and streamline the customization of my Macs.
