Auf der Suche nach preisgünstigen Alternativen habe ich zudem noch diesen Speicher erfolgreich getestet:
Crucial SO-DIMM 16GB, DDR4-2666, CL19-19-19 (CT16G4SFRA266)

https://www.amazon.de/Crucial-CT16G...C4VKYFG/dp/B08C4VKYFG/ref=dp_ob_title_ce?th=1
Dieser Speicher wurde mir bei Amazon als "Nachfolgemodell" zu dem beliebten, aber kaum noch lieferbaren Speicher "CT16G4
SFD8266" angezeigt:
