Interchangeability is based on matching JEDEC specifications (type, form factor, capacity, speed, rank organization). Individual servers may qualify only specific vendors. Confirm against your server's qualified parts list before mixing.

Practical rule: servers accept these modules interchangeably in almost all cases. Keep one vendor within a memory bank and match existing modules when expanding, rather than mixing brands side by side.
