Choosing memory for a B860 board

Install modules in matched pairs in the slots your board manual marks for two-module use, and use identical modules when filling all slots. NEMIX RAM modules are JEDEC-standard, so they run at the board's default memory settings with no XMP or EXPO profile to set; faster modules run at the speed the platform supports. Browse by module type: DDR5 UDIMM.
