Exact-Match DDR5 Upgrade for Supermicro H13SRH

This 64GB kit delivers two 32GB DDR5 6400 modules built to the precise rank, voltage and timing the H13SRH memory controller expects. Registered ECC architecture ensures full-capacity recognition at rated speed without manual tuning.

Who This Suits and Who Should Look Elsewhere

Server administrators populating a Supermicro H13SRH with validated RDIMMs will meet the board's population rules immediately. Builders needing UDIMMs, SODIMMs, non-ECC memory or capacities beyond this 64GB kit must select a different product.

Capacity and Headroom

Two 2Rx8 modules provide 64GB of registered ECC memory at 1.1V, handling multi-VM workloads and large datasets with single-bit error correction. The dual-rank design supports full-slot populations, while the fixed 64GB limit means larger memory tiers require a different kit.

Questions about this item

Does my Supermicro H13SRH motherboard need to support DDR5 6400 Registered ECC RDIMMs for this kit to work?

Yes, the H13SRH must accept 288-pin DDR5 RDIMMs at 6400 MT/s with 1.1 V operation and registered ECC; otherwise the modules will not be recognised or run at rated speed.

Can I mix this 2Rx8 6400 CL52 kit with other DDR5 RDIMMs of different rank or speed already installed in the server?

Mixing ranks or speeds forces the memory controller to run all slots at the lowest common speed and may violate the board's population rules, so consult the H13SRH manual for approved configurations.

How can I verify the kit is running at DDR5 6400 CL52 1.1 V with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to confirm each DIMM shows 6400 MT/s, CL52, 1.1 V, registered ECC mode, and the full 64 GB capacity reported without errors.
