NEMIX RAM

NEMIX RAM DDR5 4800 384GB 4x96GB ECC RDIMM CL40 1.1V 2Rx4 memory upgrade

SKU CH-Z4AY-ETS2K

A 384 GB DDR5-4800 ECC registered server kit in four 96 GB modules at CL40 and 1.1 V for the Supermicro X14SDV-20C-SP3F

  • Total capacity384 GB (4 × 96 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 384GB 4X96GB

  • 384 GB total capacity lets you run large databases and virtualization workloads without swapping
  • Four 96 GB modules fill every slot at the rated 4800 MT/s speed for maximum throughput
  • Registered ECC design corrects single-bit errors on the fly to prevent silent data corruption
  • 1 V operation reduces power draw and heat in dense server configurations
  • Verified fit for the Supermicro X14SDV-20C-SP3F motherboard ensures the memory controller recognises the full kit at rated timings

Exact-fit DDR5 server kit

This 384 GB kit consists of four 96 GB DDR5 4800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDV-20C-SP3F motherboard expects. It targets administrators who need maximum capacity in every slot without down-clocking or population errors.

Verify board population rules

Before ordering, consult the system or motherboard manual for supported capacities, approved DIMM population order and installation steps. The modules are 288-pin registered RDIMMs that operate at 1.1 V with CL40 latency, and the board must accept 2Rx4 organisation at full speed.

Registered ECC stability

Registered buffering offloads the memory controller so all four slots run fully populated at rated speed, while on-die ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots. The kit includes only the four RDIMMs; no heat spreaders or additional software are supplied.

Questions about this item

Does the kit include all four 96 GB modules or must they be purchased separately?

The kit ships as a matched set of four 96 GB DDR5 4800 RDIMMs, giving the full 384 GB capacity in one package.

Should I choose a different speed or latency if my Supermicro X14SDV-20C-SP3F board supports higher DDR5 rates?

This kit is an exact-match upgrade validated for DDR5 4800 CL40 at 1.1 V; using a different speed or timing may prevent the board from recognising the full 384 GB at rated performance.

What does the DDR5 4800 PC5-38400 rating mean when the modules are installed in the Supermicro X14SDV-20C-SP3F?

The modules will run at 4800 MT/s with CL40 latency and 1.1 V, delivering the registered ECC bandwidth and error correction the board's memory controller expects for full-capacity operation.
