Exact-match DDR5-6400 RDIMM kit for Supermicro

This 256GB kit contains sixteen 16GB DDR5-6400 (PC5-51200) registered ECC RDIMMs. Each module runs at 1.1V with CL52 latency and 1Rx8 organisation. The 288-pin RDIMM form factor matches the motherboard's memory-controller requirements for full-capacity recognition at rated speed.

Suited for servers needing maximum registered ECC

Ideal for administrators populating every slot on a Supermicro H14DSG-O-CPU board with validated registered ECC memory. Not suitable for systems that require unbuffered UDIMMs, SODIMMs, non-ECC modules, or a different DDR generation. Buyers needing lower capacities or alternative speeds should verify their platform's qualified-vendor list first.

Sixteen ranks deliver 256GB at DDR5-6400

The 1Rx8 registered design lets the memory controller drive all sixteen slots at the full 6400MT/s data rate with ECC protection. Headroom exists for heavily threaded workloads and large in-memory datasets. Capacity runs out when the application footprint exceeds 256GB or the platform's maximum supported memory per socket is lower than the installed total.

Perguntas sobre este artigo

What motherboard must I have for this 256GB DDR5-6400 ECC RDIMM kit to be recognised at full capacity?

The kit is verified for the Supermicro H14DSG-O-CPU motherboard; its memory controller expects 1Rx8 registered ECC modules at 1.1V with CL52 timing, and the board’s 288-pin RDIMM slots match the kit exactly.

Can I mix these 1.1V CL52 registered ECC RDIMMs with slower DDR5 modules already installed in the same H14DSG-O-CPU system?

The board will down-clock all populated slots to the slowest common speed and loosest timing, so every module must be rated for DDR5-6400 CL52 at 1.1V to keep the kit running at its rated 6400 MT/s.

After installation, how can I confirm the full 256GB kit is running at DDR5-6400 with ECC active?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 256GB total, 16 modules, speed 6400 MT/s, type DDR5, ECC enabled, and registered (buffered) operation.
