OWC 5R6D52R464GB 64GB DDR5 5600 ECC Registered RDIMM memory upgrade

SKU CH-07MN-BHSVY

64GB DDR5 5600 ECC Registered RDIMM module for Supermicro SuperBlade servers

  • Total capacity64 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • CAS latency46
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 64GB

  • 64 GB capacity expands server memory headroom
  • DDR5 5600 speed delivers high bandwidth for demanding workloads
  • ECC registered design protects data integrity in critical applications
  • 1 V operation reduces power draw per module
  • Validated for Supermicro SuperBlade SBI-411E, SBI-421E and SBI-611E systems

Server memory upgrade

This 64 GB DDR5 5600 ECC Registered RDIMM is built for Supermicro SuperBlade SBI-411E-1G, SBI-411E-5G, SBI-421E-1T3N, SBI-421E-5T3N and SBI-611E-1C2N systems. It delivers 1.1 V operation and CL46 latency in a single 2Rx4 module.

Replaces lower-capacity DDR5 RDIMMs

The jump is worth it when a blade chassis needs maximum memory density per slot to support larger virtualisation workloads or in-memory databases. It will not work in standard desktop boards and cannot be mixed with unbuffered or load-reduced DIMMs.

Fits 288-pin registered DDR5 slots

The module occupies one DIMM socket and requires a platform that supports registered ECC DDR5 at 5600 MT/s. It frees remaining slots for additional capacity while maintaining signal integrity across the blade enclosure.

Questions about this item

Will the 288-pin DDR5 RDIMM fit the memory slots on a Supermicro SuperBlade SBI-411E-1G?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor required by the SuperBlade SBI-411E-1G and the other listed SuperBlade models.

What is the correct seating procedure for this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both ejector clips click shut, and verify the module height matches adjacent DIMMs; the step often missed is confirming the clips are fully locked on both sides.

When should this 64GB 2Rx4 DDR5 5600 module be replaced?

Replace it if memory diagnostics report uncorrectable ECC errors, if the system logs recurring corrected errors, or when a capacity upgrade beyond 64GB per slot is required.
