Dit is een aardig recent bord van Gigabyte, een X570 AORUS PRO.
Er zitten twee reepjes van Corsair CMK16GX4M2B3200C16 in.
Simpelste actie is om vers RAM te regelen en te wisselen.
Als het probleem dan weg is was het een RAM-probleem.
Als het probleem er dan nog is is het een probleem met CPU of bord.

Wat me opviel in de DMI info (zie hieronder) dat een spanning van 1.2
volt gerapporteerd wordt.
De specs op tweakers melden 1.35V als (maximale?) spanning:

Is deze info correct? Volgens het internet wel...

E.e.a. is ingesteld via het XMP 1 keuzeverhaal in de BIOS om het RAM op
3200 MT te krijgen.
Ik kan nog nazien of ik de spanning van het RAM kan verhogen.
