Exact-Match 288GB DDR5-6400 Kit

This 288GB kit contains six 48GB DDR5 6400 (PC5-51200) registered ECC RDIMMs. Each module runs at 1.1V with CL52 latency and a 2Rx8 organisation. The kit is built for the Supermicro H14DSH motherboard and matches the memory controller's rank, voltage and timing requirements for full-capacity recognition.

For Supermicro H14DSH Servers Needing 288GB

Suits administrators populating every DIMM slot on a Supermicro H14DSH board with registered ECC memory at the rated speed. Not for systems that require unbuffered UDIMMs, SODIMMs, lower capacities or a different DDR generation.

288-Pin Registered ECC DDR5 Form Factor

The modules use the 288-pin RDIMM form factor with registered (buffered) architecture and on-die ECC. This exact physical and electrical interface is what the H14DSH memory controller expects; any other form factor will not fit or function.

Questions about this item

What motherboard must I already have for this 6 x 48 GB DDR5-6400 ECC RDIMM kit to work?

The kit is validated for the Supermicro H14DSH motherboard, which uses the 288-pin Registered RDIMM form factor and expects DDR5-6400 (PC5-51200) modules at 1.1 V with CL52 timing.

How will these 2Rx8 registered modules behave if I keep older DDR5 RDIMMs in the same H14DSH board?

Mixing ranks or speeds forces all slots to run at the lowest common speed and voltage; the board manual should be consulted for approved population order before adding this 288 GB kit alongside existing memory.

How can I confirm the full 288 GB is recognised and ECC is active after installation?

Check the system BIOS or OS memory report for 288 GB total capacity, DDR5-6400 speed, 1.1 V operation and ECC enabled status.
