https://www.zdnet.com/article/yes-i-bought-a-2018-mac-mini-and-heres-how-i-specd-it-out/ Fortunately, the new Mac mini allows for RAM upgrades. The Apple spokesperson I spoke to last week told me, "Yes, Mac mini is configurable up to 64GB and uses industry-standard DDR4 SO-DIMMs. While we don't consider the memory directly end-user accessible, service providers can access the internals of the Mac mini to upgrade the memory."
Since the 32GB upgrade is a whopping $600 more than the base 8GB unit, I opted for the 8GB unit. I then went over to Amazon and picked up some Corsair Vengeance Performance 32GB (2x16GB) 260-Pin DDR4 SO-DIMM (PC4 21300) RAM. That set me back $288 instead of $600.
While Apple has not been entirely clear on what it means by "service providers," Tim Cook did go out of his way to state that the Mac mini supports SO-DIMM modules. I'm honestly not entirely sure what I'll encounter when the Mac arrives, but I'm sure it'll be interesting.
Stay tuned, because once the machine arrives, I'll do a piece on what it takes to add the RAM.
