Exact-match DDR5 kit for Supermicro H13SRH

This 1 TB kit contains eight 128 GB DDR5 6400 RDIMM modules built to the CL52 1.10 V 2Rx4 specification the H13SRH memory controller expects. Registered ECC architecture allows every slot to be populated at full capacity while correcting single-bit errors on the fly. The 288-pin form factor matches the board's DIMM sockets precisely.

Kit contents and verified fitment

The package delivers the complete 1 TB configuration in a single matched set, eliminating the risk of mixing ranks or speeds that can prevent the server from booting. Compatibility is confirmed for the Supermicro H13SRH motherboard, so the modules are recognised at their rated DDR5 6400 speed without manual timing adjustments.

Suited for fully populated H13SRH deployments

Ideal for administrators expanding a Supermicro H13SRH to its maximum supported memory using registered ECC DIMMs. Not suitable for systems that require unbuffered UDIMMs, SODIMM form factors, or lower-density modules outside the 2Rx4 128 GB per DIMM specification.

Questions about this item

Will the 1.1V DDR5 RDIMMs need any firmware updates or periodic replacement to maintain ECC integrity?

The modules run at the standard 1.10V DDR5 voltage with on-die ECC; no firmware updates or scheduled replacement are required for error-correction integrity.

What thermal limit appears first when all eight 128GB RDIMMs run at 6400 MT/s continuously?

The registered 2Rx4 design offloads the memory controller, so the first sustained-use limit is the motherboard's DIMM-slot airflow rating rather than the modules themselves.

How much extra power draw and fan noise should I expect from the full 1TB kit under 24/7 load?

At 1.10V each 128GB RDIMM adds minimal incremental power; total kit draw stays within the H13SRH's standard memory-phase budget, so existing chassis fans handle cooling without audible increase.
