  • 288 GB total capacity from six 48 GB modules for large-scale server workloads
  • DDR5-4800 speed with CL40 latency delivers rated bandwidth on compatible platforms
  • Registered ECC architecture offloads the memory controller and corrects single-bit errors
  • 1 V operating voltage reduces power draw per module in dense configurations
  • Exact-fit 288-pin RDIMM kit validated for Supermicro H14SHM motherboard

Exact-match DDR5 ECC RDIMM kit

This 288GB kit contains six 48GB DDR5 modules rated at 4800MHz with CL40 latency and 1.10V operation. Registered ECC architecture with 2Rx8 organisation is designed for the Supermicro H14SHM motherboard. It targets server builds that require maximum registered capacity and error correction.

Thermals and power draw

Modules operate at the standard 1.10V DDR5 voltage without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller when all slots are populated. Power consumption scales with the fully populated 288GB configuration at rated speed.

Build integration

The 288-pin RDIMM form factor fits only boards that support registered DDR5 memory and the specific population rules of the H14SHM. No UDIMM or SODIMM slots will accept these modules. Installers must follow the motherboard manual for approved DIMM order and maximum supported capacity per channel.

Questions about this item

How do I install the six 48 GB DDR5 RDIMMs in the Supermicro H14SHM, and which slot-population step is most often missed?

Populate the six 288-pin RDIMM slots in the exact order listed in the H14SHM manual so the memory controller sees the 2Rx8 ranks at 1.1 V and 4800 MT/s; skipping the prescribed sequence is the step that causes partial capacity detection.

What maintenance or replacement will this 288 GB DDR5 ECC RDIMM kit need during its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; only a DIMM that develops uncorrectable ECC errors would need replacement under the lifetime warranty.

What is the first limit reached when all six 48 GB RDIMMs run sustained workloads at 4800 MT/s?

The registered buffer and 1.1 V operation keep every slot at the rated 4800 MT/s CL40, so the practical ceiling is the motherboard's maximum supported capacity rather than a thermal or signal-integrity bottleneck.
