Title: max memory speeds
Post by: pocock on July 31, 2020, 03:46:40 pm

AbstractConcept made this edit in the wiki (https://wiki.raptorcs.com/w/index.php?title=RCS_Platform_Comparison&oldid=3303)

I read somewhere that RAM operates at different speeds (https://wiki.raptorcs.com/wiki/POWER9_Hardware_Compatibility_List/Memory#Compatibility_rules):

1 channel filled: 2666MHz

2 channels filled: 2400MHz

4 channels filled: 2133MHz

but the edit by AbstractConcept implies that RAM is always clocked at 2666MHz

Can anybody clarify?
