Update to this issue : i have finally open my Nucleus On Box, replaced the original RAM which is a Neo Forza DDR4 SODIMM 3200 C22 with only 4Gb
by a new Crucial DDR4 3200 CL22 “notebook” 16Gb model
and guess what ? No crashes or reboot for my Roon Server Software since more than 24h and of course everything is faster and even the Backup (automatic or manual) works just fine and do not interrupt after a while.
It’s like a rebirth and reconciliation with my Roon Nucleus box !
I really love Roon products and now I will start to enjoy the all setup.
Thks.
