Can you really upgrade the RAM in the M1 2020 Mac Mini to 64 Gigs?

I think this sites claims to sell Mac Mini 2020 M1 Ram Upgrades to 64gb https://www.crucial.com/compatible-upgrade-for/apple/mac-mini-%282020%29

--but--

Everymac.com and the Verge.com both claim the RAM limit is 16gb and is not upgradable. I don’t understand the confusion from these sites or am looking at old articles, not finding the correct links for new M1 Macs.

Can the M1 Macs get aftermarket RAM upgrades?

No RAM upgrade - you would need to reflow new processor board or be skilled enough to rework the one you have.

RAM Memory on the Apple Silicon M1 Processor is integral to system package “chip” that’s mounted as one unit to the logic board. There is no slot or place to add memory on the M1 based Air, Pro or Mini. The SSD chips have separate placement on the logic board from the Processor board. Everything is soldered to the logic board for Apple Silicon Minis.

I would not mistake an 8 GB RAM Air, Pro or Mini for anything but a beast of a workstation for most tasks. Real world benchmarks are showing them completing work dramatically faster than 12 core Mac Pro with 32 GB of RAM.

Pick any ten apps you want to start and race the entry level Air with any Mac of your choosing - iMac Pro, Mac Pro, or an 8 core MacBook Pro - there are only few specialized tasks where the Air is slower.

The 2020 Intel mini is still available and that’s what crucial and others are selling memory.

Note there is an Intel Mac mini 2020 https://www.apple.com/uk/shop/buy-mac/mac-mini/3.0ghz-intel-core-i5-6-core-processor-with-intel-uhd-graphics-630-512gb# which has 8gb RAM

So the crucial description is correct for intel processors, incorrect for M1 based Minis.
