Voir les 6 autres configurations
  • 256 GB total capacity with four 64 GB modules for maximum server density
  • DDR5-6400 speed rated at PC5-51200 for high-throughput workloads
  • CL52 latency at 1.10 V for efficient registered operation
  • 2Rx4 ECC registered RDIMM architecture prevents silent data corruption
  • Verified fitment for Supermicro H13SRA-F and H13SRA-TF motherboards

Exact-match server upgrade

This 256 GB kit contains four 64 GB DDR5 registered ECC RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. The modules use a 2Rx4 organisation and 288-pin form factor to match the memory controller expectations of the Supermicro H13SRA-F and H13SRA-TF motherboards.

Suited for fully populated enterprise servers

The registered buffer and on-die ECC allow every slot to run at full capacity while correcting single-bit errors in flight. Buyers who need unbuffered UDIMMs, SODIMMs, or non-ECC memory for workstation or consumer platforms should look elsewhere because this kit is built for the specific registered RDIMM topology these server boards require.

Verify board population rules before ordering

Consult the motherboard manual for the approved DIMM population order, maximum supported capacity per channel, and any BIOS version requirements for DDR5 6400 operation. Confirm that your chassis provides clearance for standard-height RDIMMs and that the power budget accounts for the additional modules.

Questions sur cet article

Do I need a Supermicro H13SRA-F or H13SRA-TF motherboard for this 256GB kit to work?

Yes, the 4x64GB DDR5 6400 CL52 2Rx4 Registered ECC RDIMM kit is validated for those two Supermicro motherboards and their DDR5 6400 memory controller.

Can I mix these 2Rx4 Registered ECC modules with older DDR5 UDIMMs in the same server?

No, Registered RDIMMs and unbuffered UDIMMs use different electrical signalling and cannot be installed together on the H13SRA-F or H13SRA-TF platforms.

How do I confirm the kit runs at 6400 MT/s with CL52 after installation?

Check the BIOS memory information or run a tool such as dmidecode to verify speed shows 6400 MT/s, CAS latency 52, voltage 1.1V and all four 64GB ranks detected.
