NEMIX RAM

NEMIX RAM 16GB DDR5 4800 CL40 1.1V 288-Pin UDIMM SuperMicro Compatible memory upgrade

SKU CH-B00Y-4QKBY

16 GB DDR5 desktop module running at 4800 MHz with CL40 latency and 1.1 V operation

  • Capacity16GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCNo
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V

Capacity 16GB

  • 16GB capacity expands SuperMicro system memory
  • DDR5 4800 speed delivers PC5-38400 bandwidth
  • 1V operation reduces power draw
  • CL40 latency supports responsive workloads
  • 288-pin UDIMM fits compatible SuperMicro boards

SuperMicro DDR5 4800 Compatible Memory

This 16 GB DDR5 UDIMM is validated for SuperMicro desktop and SuperWorkstation platforms such as the MBD-C9Z790-CG. It targets IT professionals and builders who need a single, stress-tested module for mission-critical stability in enterprise or high-end workstation builds.

16 GB Capacity and CL40 Latency Headroom

The single-rank 1Rx8 layout delivers 16 GB at 4800 MT/s with CL40 timings at 1.1 V. This density handles mainstream multi-tasking and typical workstation workloads comfortably. Demanding virtualisation clusters or large in-memory databases will exhaust the capacity before the bandwidth limit is reached.

DDR5 UDIMM Interface Practical Limits

The 288-pin unbuffered DDR5 interface tops out at the JEDEC 4800 MT/s baseline without overclocking headroom. Systems requiring ECC error correction, registered buffering or speeds beyond PC5-38400 must select a different module type because this stick provides none of those features.

Questions about this item

Will this 16GB DDR5 4800 CL40 module work with the existing DDR5 memory already installed in my SuperMicro C9Z790-CG system?

The module runs at 4800 MHz with CL40 latency and 1.10 V. It will operate alongside other DDR5 UDIMMs at the highest common speed and timing the motherboard negotiates.

How can I confirm the module is running at 4800 MHz and CL40 after installation?

Enter the system BIOS or use a tool such as CPU-Z to verify the memory frequency reads 4800 MHz (PC5-38400) and the CAS latency shows CL40 at 1.10 V.

Does the package include only the 16GB UDIMM or are extra items like a heat spreader or installation tool supplied?

The box contains a single 16 GB 288-pin DDR5 UDIMM (part MD38400-618K1) with no heat spreader and no additional accessories.
