In the last few minutes apple.com has been updating with documentation for new products.

But this page lists these specifications for the RAM for the 2017 iMac:



While the manual states differently:



Which is correct?

I believe that the DDR3 so-simms have 204 pins, whereas the DDR4 so-simms have 260 pins. It is unfortunate that there's inconsistency between these 2 Apple-sourced pieces of information.

Actually, the manual has an error of its own.

It refers to the SODIMMs as type PC4-2400, when in fact the correct denomination is PC4-19200.

It blows my mind that a company as big as Apple can make such simple (yet confusing for newbies) mistakes on two different occasions...

This error remains. I will re-open the bug report with this issue.
