Exact-match DDR5 kit for Supermicro H13SRA

This 96GB kit delivers two 48GB DDR5 6400 CL52 ECC RDIMM modules built to the exact rank, voltage and timing the Supermicro H13SRA-F and H13SRA-TF memory controller expects. The 2Rx8 registered design with 1.10V operation ensures full capacity recognition at rated speed without manual tuning. It is not for systems that require UDIMM or SODIMM form factors, or for boards limited to lower DDR5 data rates.

Straightforward RDIMM installation

Align the 288-pin modules with the keyed slots and press until the retention clips engage; registered DIMMs seat with the same force as standard server memory. The most common issue is populating slots in an order the motherboard firmware does not support, which can leave capacity unrecognised or force a reduced speed. Always follow the board manual's population sequence and verify firmware is current before powering on.

Verify motherboard rules before ordering

Confirm your Supermicro H13SRA-F or H13SRA-TF revision supports 48GB per slot and the total 96GB capacity with 2Rx8 registered ECC modules. Check the approved DIMM population order, maximum supported speed with two DIMMs installed, and any BIOS version requirements listed in the system documentation. This kit is not suitable for platforms that only accept unbuffered DDR5 or that cap registered memory at lower densities.

Questions about this item

How can I confirm the 96GB kit is running at DDR5 6400 with CL52 after installation?

Enter the BIOS or UEFI on the Supermicro H13SRA-F or H13SRA-TF motherboard and verify the memory speed shows 6400 MT/s, CAS latency 52, voltage 1.10 V, and total capacity 96 GB across both 48 GB modules.

What comes in the box and is anything else required to install the MR51200-4828K2 kit?

The package contains two 48 GB DDR5 288-pin ECC Registered RDIMM modules. No additional parts are needed; the motherboard provides the slots and power for the 1.10 V modules.

Which capacity version should I choose for a Supermicro H13SRA-TF that supports up to 96 GB per channel?

This 96 GB kit (2 x 48 GB, 2Rx8) matches the board's DDR5 6400 PC5-51200 registered ECC specification and fills two DIMM slots for full rated performance.
