NEMIX RAM DDR5 ECC RDIMM 256GB 4x64GB 6400 CL52 1.1V 2Rx4 Supermicro H13SSW

SKU CH-R9EH-M5YYQ

256GB DDR5 ECC registered RDIMM kit, four 64GB modules at 6400MHz CL52 1.1V, validated for Supermicro H13SSW servers

  • Capacity256GB (4 x 64GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 256 GB total capacity across four 64 GB modules for maximum memory density
  • DDR5-6400 speed with CL52 latency delivers rated throughput on supported platforms
  • Registered ECC architecture corrects single-bit errors and offloads the memory controller
  • 10 V operation matches the module voltage your server expects
  • Verified fitment for the Supermicro H13SSW motherboard with 288-pin RDIMM form factor

Exact-Match Server Upgrade

This 256GB kit provides four 64GB DDR5 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H13SSW memory controller expects. The modules install as a matched set so the board recognises the full capacity and runs at the rated 6400 speed without manual tuning.

Sustained Enterprise Stability

Registered architecture offloads the memory controller, allowing every slot to stay fully populated at full capacity during continuous workloads. On-die ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots from reaching production systems.

When the Jump Is Worth It

The kit replaces smaller or slower DDR5 RDIMM configurations when the platform requires maximum registered capacity per channel. It is not for boards that accept only UDIMM or SODIMM form factors, nor for systems limited to lower densities or speeds.

Spørgsmål om denne vare

How much power does the 1.1V DDR5 6400 kit draw when the H13SSW runs fully populated 24/7?

The modules operate at 1.1V DDR5 standard voltage; Registered ECC architecture reduces electrical load on the memory controller when all four slots are populated, helping keep sustained power draw within the board's designed envelope.

What motherboard and firmware must I already have for this 256GB 4x64GB kit to be recognised at full speed?

A Supermicro H13SSW motherboard with BIOS updated to a version that supports 256GB total capacity, DDR5 6400 RDIMM, 2Rx4 organisation and CL52 timings; the kit is spec-matched to that board's population rules.

Will the lack of heat spreaders on these RDIMMs cause thermal throttling next to older passively cooled DIMMs in the same chassis?

These modules ship without heat spreaders and rely on the H13SSW's standard DIMM-slot airflow; as long as the server's fan profile meets the board's cooling specification, the 1.1V 2Rx4 RDIMMs run within thermal limits alongside other DDR5 Registered ECC DIMMs.
