  • Rated speedDDR5 4800 (PC5 38400)
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeUnbuffered
  • Recommended forDesktops

Capacity 16GB

  • 16 GB DDR5 module expands desktop capacity for heavier workloads
  • 4800 MT/s speed rating delivers higher bandwidth than older standards
  • CL40 latency keeps response times tight during multitasking
  • 1 V operation reduces power draw and heat output
  • 288-pin UDIMM form factor fits standard desktop DIMM slots

Single-module 16 GB upgrade

This single 16 GB DDR5 module runs at 4800 MT/s with CL40 timing and 1.1 V operation. It is an unbuffered, non-ECC UDIMM built for desktop, workstation, NAS and all-in-one systems.

Cool, quiet, low-voltage operation

Operating at the JEDEC-standard 1.1 V keeps power draw and heat low without a heat spreader. The module produces no fan noise of its own and adds minimal thermal load inside the chassis.

288-pin UDIMM fits standard slots

The 288-pin form factor slots directly into any compatible DDR5 DIMM socket. No extra cables, brackets or software are required, leaving all other expansion slots and drive bays free.

Questions about this item

Will this DDR5 module fit my motherboard's 288-pin UDIMM slots?

Yes, it uses the standard 288-pin unbuffered DIMM form factor for desktop DDR5 memory.

Does the 1.1V operating voltage require any special BIOS settings?

No, 1.1V is the standard JEDEC voltage for DDR5, so the module runs at spec without manual adjustment.

Can I use this non-ECC memory in a workstation or NAS that supports ECC?

Yes, the compatibility list includes workstations and NAS systems; non-ECC modules work in boards that do not require ECC.
