48 GB DDR5 RDIMM for Supermicro H13SST-G

This 48 GB DDR5-6400 Registered ECC module matches the exact rank, voltage and timing the Supermicro H13SST-G memory controller expects. It installs as a 288-pin RDIMM so the board recognises the full capacity at rated speed without manual tuning.

Who this suits and who should look elsewhere

Server builders who need a single 48 GB Registered ECC DIMM validated for the H13SST-G platform will find the correct spec here. Buyers who want unbuffered UDIMMs, SODIMM form factors, non-ECC memory or capacities other than 48 GB per module must choose a different part.

Registered ECC with 2Rx8 organisation

The 2Rx8 Registered ECC architecture offloads the memory controller and corrects single-bit errors on the fly, allowing full-slot population at the rated 6400 MT/s speed with 1.1 V operation.

Questions about this item

Does the package include only the 48GB RDIMM or are cables and a heat spreader also supplied?

The box contains the 48GB DDR5 6400MHz 2Rx8 1.1V CL52 288-pin ECC Registered RDIMM. No heat spreader or cables are included.

Is the 48GB 2Rx8 CL52 module the only capacity and rank offered for this Supermicro H13SST-G kit?

This listing is a single 48GB 2Rx8 RDIMM at 6400MHz CL52. Other capacities or ranks are separate part numbers.

Will the rated 6400MHz speed and CL52 latency run automatically on the H13SST-G, or is manual BIOS tuning required?

The module is spec-matched to the H13SST-G memory controller, so it is recognised at full 6400MHz and CL52 without manual tuning.
