Exact-match server kit

This 256GB kit provides sixteen 16GB DDR5 4800 RDIMMs built to the precise specifications of the Supermicro H14DSH motherboard. Each module operates at 1.1V with CL40 latency and 1Rx8 registered ECC organisation. The memory controller recognises the full capacity at rated speed without manual tuning.

Registered ECC headroom

Registered architecture offloads the memory controller so all sixteen slots can be populated at full capacity while ECC corrects single-bit errors on the fly. The kit delivers 256GB of protected memory for virtualisation, databases and large datasets. Workloads that exceed this capacity or require faster than DDR5 4800 speeds will need a different platform.

288-pin RDIMM form factor

The modules use the 288-pin RDIMM form factor required by the H14DSH and omit heat spreaders for dense server chassis airflow. Installation must follow the motherboard manual population order for full recognition. Builders using consumer UDIMMs, SODIMMs or non-ECC memory cannot use this kit.

Questions sur cet article

Will the 16 288-pin DDR5 4800 RDIMMs run alongside any existing DDR5 RDIMMs already installed in my Supermicro H14DSH?

Mixing kits is not recommended. The server's memory controller expects identical rank, voltage and timing across every populated slot; this kit uses 1Rx8 modules at 1.1 V CL40, so adding modules with different specifications can prevent full-speed operation or cause boot failures.

How can I verify the kit is running at DDR5 4800 CL40 1.1 V after installation?

Enter the BIOS or use a hardware-information tool such as CPU-Z or dmidecode; each module should report 4800 MT/s, CAS latency 40, 1.1 V and Registered ECC 1Rx8. The Supermicro H14DSH will also display the total 256 GB capacity during POST when all 16 slots are filled.

Does the package contain only the 16 RDIMMs or are any cables, brackets or tools included?

The box contains only the 16 x 16 GB DDR5 4800 ECC Registered RDIMMs. No cables, brackets, heat spreaders or installation tools are supplied; the modules install directly into the 288-pin DIMM sockets on the motherboard.
