Memory upgrades for 2019 Mac Pro: "largest to smallest" capacity

But it says "starting with the lowest capacity... install from smallest to largest"

your change would make the language in that one sentence inconsistent.

Do you have another source to bolster you assertion that it should be largest to smallest?

I can see PuckettM's point. On that URL - you see the wording in the section "Installing DIMMs of mixed capacities" stating that "starting with the lowest capacity... install from smallest to largest capacity in order of the memory channels". To me, that would imply that the lowest capacity memory goes in memory channel 1 (slots 5 to 8), and the highest capacity DIMMs go in the higher numbered memory channels.

But scroll down to the "Verify your memory" section and look at the screenshot where 8Gb and 32Gb DIMMs are mixed. The 32Gb pairs go in slots 5 to 8, which is memory channel 1 and slots 3 and 10 (memory channel 2). The 8Gb DIMMs go in memory channels 3 and 4. That would not represent installing "from smallest to largest capacity in order of the memory channels".

It seems as if you'd be as well putting them in whichever order you like and then letting macOS tell you where they should go!

There is a long history of always installing highest density DIMMs in the "first" slots.

There has been another User reporting that this lowest to highest language actually does not work in practice.

I have asked Moderators to have this escalated to be clarified. Apple corporate shuts down for end-of-year, so it may be a while before more concrete information is available.
