severity 1001286 important
thanks
Same restriction here, namely for two stationary computers with Asus WS C422 PRO/SE with Intel® Xeon® W-2235 CPU @ 3.80GHz (motherboard specification: https://www.asus.com/de/motherboards-components/motherboards/workstation/ws-c422-pro-se/techspec https://www.asus.com/de/motherboards-components/motherboards/workstation/ws-c422-pro-se/techspec ).

Raising severity because more than two machines are concerned. Though it's not urgent (or at least not urgent for me in any sense of the word) because currently I don't have that much RAM to populate all the slots, it's important to eventually remove the restriction because I'm quite sure that I am going to add RAM in the future. All my computers so far ended their lives with the maximal amount of RAM.
Gratefully,
AlMa
