384GB DDR5 6400 ECC RDIMM Kit

This 384GB kit contains twelve 32GB DDR5 6400 modules built for the Supermicro H13DSH motherboard. Each module is a 288-pin Registered ECC RDIMM operating at 1.1V with CL52 latency. The kit targets administrators upgrading memory capacity in compatible Supermicro server platforms.

Full Population at Rated Speed

Twelve dual-rank 2Rx8 modules fill every slot while maintaining DDR5 6400 (PC5-51200) operation. Registered buffering offloads the memory controller so all slots run at full capacity without downclocking. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads.

288-Pin Registered Form Factor

Modules use the 288-pin RDIMM layout required by the H13DSH; UDIMM or SODIMM alternatives will not fit. No heat spreaders are present, so airflow across the DIMMs must follow the chassis design. Buyers needing a different capacity, rank configuration, or non-ECC memory should look elsewhere.

Questions about this item

Will the 12 x 32 GB DDR5 6400 CL52 1.1 V RDIMMs populate every slot on my Supermicro H13DSH without speed down-negotiation?

The kit matches the board's DDR5 6400 PC5-51200 2Rx8 Registered ECC spec, so all twelve 288-pin slots can run at the rated 6400 MT/s with 1.10 V and CL52 timings.

How can I confirm the NEMIX RAM 384 GB kit is running at DDR5 6400 CL52 1.1 V after installation?

Enter the BIOS or use a tool such as dmidecode to verify each DIMM shows 6400 MT/s, CAS 52, 1.10 V, Registered ECC and 2Rx8 organisation.

Does the MR51200-328K12 package include only the twelve 32 GB RDIMMs or are any cables or brackets supplied?

The box contains exactly the twelve 32 GB DDR5 6400 288-pin ECC Registered RDIMMs; no cables, brackets or extra hardware are included.
