OWC DDR5 16GB Desktop Module

This OWC DDR5 UDIMM delivers 16GB of JEDEC-standard memory at 4800MHz CL40 for desktop, workstation, NAS and all-in-one systems. The unbuffered 288-pin module runs at 1.1V without ECC or a heat spreader. Part number 4U8D51R816GB replaces Hynix HMCG78MEBUA081N and HMCG78MEBUA084N.

Suits DDR5 Platforms Needing 16GB CL40

Builders upgrading a compatible DDR5 desktop, workstation or NAS will gain capacity with this single 16GB stick. Systems that require registered DIMMs, ECC support or a lower CAS latency should select a different module. The black PCB has no RGB lighting.

JEDEC DDR5 4800 CL40 1.1V 288-pin UDIMM

The decisive specification is the JEDEC DDR5 4800 CL40 1.1V unbuffered 288-pin form factor. Only motherboards and controllers that accept this exact speed, latency, voltage and pin layout will run the module at its rated settings.
