OWC 5R6D52R464GB 64GB DDR5 5600 ECC RDIMM memory upgrade

SKU CH-2KNH-HGY7D

A 64 GB DDR5 5600 ECC registered RDIMM for compatible Supermicro SuperServer workstations and servers

  • Capacity64GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS Latency46
  • Voltage1.1V
  • ECCYes

Capacity 64GB

  • ECC registered design protects data integrity in servers
  • 64GB single module expands memory capacity efficiently
  • DDR5 5600 speed delivers high bandwidth for workloads
  • 1V operation reduces power consumption per module
  • Validated for specific Supermicro SuperServer models

Server Memory Upgrade

This OWC 64GB DDR5 5600 ECC Registered RDIMM is built for Supermicro SuperServer SYS-121C-TN2R, SYS-121H-TNR, SYS-211E-FRDN13P, SYS-211E-FRDN2T and SYS-211E-FRN13P systems. It targets administrators who need to expand memory capacity in compatible workstation or server platforms.

Replacing Lower Capacity Modules

The 64GB dual-rank module upgrades from smaller DIMMs when the platform supports DDR5 5600 PC5-44800 CL46 at 1.1V. The jump is worth it when workloads demand higher density per slot and the server qualifies registered ECC memory.

Verify Platform Compatibility

Confirm the exact SuperServer model matches the listed SYS-121 or SYS-211 part numbers before ordering. This registered ECC RDIMM will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced memory types.

Perguntas sobre este artigo

What slot type and pin count does the 64 GB DDR5 module need to fit in a Supermicro SuperServer SYS-211E-FRDN2T?

The module uses a 288-pin DDR5 RDIMM form factor, so the server must provide a matching 288-pin DDR5 DIMM slot.

How do you install the 64 GB ECC Registered DIMM, and which step do installers often miss?

Power down the server, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 5600 MHz speed and ECC are active — skipping the BIOS check is the common oversight.

What ongoing care does the 64 GB DDR5 5600 CL46 RDIMM require in a Supermicro SuperServer SYS-121H-TNR?

No scheduled maintenance is needed; keep the server air filters clean so the 1.1 V module stays within thermal limits, and replace the DIMM only if memory diagnostics report correctable or uncorrectable ECC errors.
