NEMIX RAM 128GB DDR5 6400MHz PC5-51200 4Rx4 1.1V CL52 288-PIN ECC RDIMM memory upgrade

SKU CH-9V0G-S5KJQ

128GB DDR5 6400MHz registered ECC server module with 4Rx4 rank, CL52 latency, 1.1V operation, and 288-pin RDIMM form factor validated for Supermicro X14SDW-42C-SP9F motherboards

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 128GB

  • 128 GB capacity for high-density server workloads
  • DDR5 6400 speed rated at PC5-51200 bandwidth
  • CL52 latency at 1.1 V operating voltage
  • 4Rx4 registered ECC architecture for error correction
  • 288-pin RDIMM form factor matches Supermicro X14SDW-42C-SP9F

Exact-fit server memory

This 128GB DDR5 6400MHz PC5-51200 4Rx4 1.1V CL52 288-pin ECC RDIMM is built for the Supermicro X14SDW-42C-SP9F motherboard. The registered architecture and ECC function match the board's memory controller requirements so every slot can be populated at the rated speed.

Replacing slower or smaller modules

Upgrade from lower-capacity DDR5 RDIMMs when your workload needs the full 128GB per module at 6400MHz without down-clocking. The jump is worth it when the manual confirms this exact rank, voltage and timing combination for full population.

Build integration

The 288-pin RDIMM form factor fits the Supermicro X14SDW-42C-SP9F memory slots directly — no UDIMM or SODIMM alternative will seat correctly. Registered buffering offloads the memory controller, freeing electrical margin for dense population across all channels.

Perguntas sobre este artigo

Will this 288-pin DDR5 RDIMM fit the memory slots on my Supermicro X14SDW-42C-SP9F motherboard?

Yes, the module uses the 288-pin RDIMM form factor required by that board. It is not a UDIMM or SODIMM, so it matches the slot keying and electrical interface exactly.

What is the correct installation sequence for this 4Rx4 registered ECC module on the X14SDW-42C-SP9F?

Consult the motherboard manual for the approved DIMM population order. Registered modules must be installed in the specific slot sequence the board expects, otherwise the system will not recognise the full 128 GB capacity.

Does the lack of a heat spreader on this 1.1 V DDR5 module mean I need to add active cooling later?

The module runs at the standard 1.1 V DDR5 voltage without a spreader. In a server chassis with normal airflow this is sufficient; additional cooling is only needed if your enclosure restricts air movement over the DIMM slots.
