Black Diamond Memory BD16G4800MC28 16GB DDR5 4800 CL40 288-Pin UDIMM 1.1V memory upgrade

SKU CH-5BJF-65AQW MPN BD16G4800MC28

A 16 GB DDR5 module running at 4800 MT/s with CL40 latency and 1.1 V operation

  • Total capacity16 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • Buffer typeUnbuffered
  • 16GB capacity for multitasking headroom
  • DDR5 4800 speed for responsive performance
  • CL40 latency for stable operation
  • 1V voltage for efficient power draw
  • 288-pin UDIMM form factor for desktop compatibility

System-Specific 16GB DDR5 Upgrade

This 16GB DDR5 module runs at 4800 MT/s with CL40 latency and operates at 1.1V. It uses a 288-pin UDIMM form factor and is built as a single-rank, unbuffered non-ECC stick. The part targets owners of compatible desktops or workstations that require a direct-replacement DDR5 memory upgrade.

Buyers Needing ECC or Registered DIMMs

Systems that demand error-correcting code or registered buffering cannot use this module, as it is explicitly non-ECC and unbuffered. Builds requiring speeds above 4800 MT/s or capacities beyond 16GB per slot should look at other modules that meet those requirements.

DDR5 4800 CL40 1.1V Specification

The decisive spec is the DDR5 4800 speed rating paired with CL40 timing at 1.1V, which determines whether the memory matches the platform's supported data rate, latency budget and voltage window.

Questions about this item

Will the 288-pin DDR5 UDIMM fit my motherboard's standard DDR5 slots?

The module uses the standard 288-pin DDR5 UDIMM form factor, so it fits any desktop motherboard slot designed for DDR5 memory.

What is the correct way to seat the module so the single-rank 16GB stick is fully recognised?

Align the notch with the slot key, press down firmly until both side clips click shut, then verify 4800 MT/s in the BIOS.

Does the 1.1V CL40 module need any firmware updates or replacement over time?

No firmware updates are required; the JEDEC-standard 1.1V DDR5 module is designed to run at its rated 4800 speed for the system's lifespan.
