ADATA Premier DDR5-4800 1x16GB

This Premier listing sits in the same ADATA family as its 5600 sibling but at a slower rated grade — 4800 MT/s CL40 — and, unusually for a desktop-category listing, it's ECC memory rather than the non-ECC most consumer boards expect.

It ships as a single UDIMM stick, 1×16GB, for a total of 16GB, so there's no capacity or module-count decision here, just the one configuration on offer.

Because it's ECC, it needs a board and CPU combination that actually supports it — check that before assuming any DDR5 desktop socket will take it.
