Cause

Kontroller igjen minnestørrelsen som den brukte CPU-en støtter.

CPUen som brukes er en Xeon Gold 5218 X2.
Én enkelt CPU støtter en minnestørrelse på 1 TB.

Under denne konfigurasjonen kan 2 CPU-er støtte opptil 2 TB minne.

Minnekapasiteten til serveren har overskredet støtteområdet for CPU.

Resolution

Reduser minnekapasiteten til 2 TB.

Installer minnet i henhold til retningslinjene for systemminne i installasjons- og servicehåndboken.
