  • Total capacity256 GB (8 × 32 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank2Rx8
  • 256 GB total capacity across eight 32 GB modules for heavy server workloads
  • DDR5 6400 MHz speed with CL52 latency delivers high-throughput registered performance
  • ECC registered design detects and corrects single-bit errors for data integrity

System-Specific DDR5 ECC RDIMM Kit

This 256GB kit contains eight 32GB registered DDR5 modules built for the SuperMicro Hyper SuperServer SYS-122HA-TN-LCC. It targets administrators who need validated, high-density memory for that exact platform. Buyers with other motherboards or workstations should verify compatibility before purchasing.

256GB Capacity and Registered Headroom

Eight dual-rank 32GB modules deliver 256GB total at 6400MHz with CL52 latency and 1.10V operation. Registered buffering and ECC protect data integrity under sustained multi-threaded workloads. Systems requiring more than 256GB or higher frequencies will exceed this kit’s specification.

DDR5 RDIMM Interface Limits

The 288-pin DDR5 RDIMM form factor fits only platforms designed for registered DDR5 memory. PC5-51200 bandwidth and 2Rx8 organisation define the electrical ceiling; faster speeds or unbuffered slots are not supported. Ensure the server BIOS recognises the full 256GB configuration at rated timings.

Questions about this item

Will these DDR5 ECC RDIMM modules run alongside the existing DDR5 memory already installed in my Supermicro SYS-122HA-TN-LCC?

The kit uses DDR5 6400MHz PC5-51200 2Rx8 1.1V CL52 288-PIN ECC RDIMM Registered modules; matching those exact specifications is required for stable mixed operation.

How can I confirm the full 256GB kit is recognised and running at 6400MHz with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory information screen shows 256GB total capacity, DDR5 6400MHz speed, CL52 latency and ECC status enabled.

Does the package include only the eight 32GB DDR5 ECC RDIMM modules or are any cables, brackets or tools supplied as well?

The package content lists only the 256GB (8 x 32GB) DDR5 6400MHz PC5-51200 2Rx8 1.1V CL52 288-PIN ECC RDIMM kit; no additional accessories are included.
