Exact-match DDR5-4800 upgrade for Supermicro H14DSH

This 256GB kit delivers four 64GB DDR5 RDIMMs at 4800MHz PC5-38400 with CL40 timing and 1.10V operation. Registered ECC architecture meets the precise rank, voltage and timing requirements of the Supermicro H14DSH motherboard so the system recognises full capacity at rated speed.

Sustained enterprise workload stability

Registered buffering offloads the memory controller allowing every slot to run fully populated at full capacity without signal degradation. ECC corrects single-bit errors on the fly preventing silent data corruption and unplanned reboots during continuous production workloads.

Bare-module form factor and population rules

Modules ship without heat spreaders as standard 288-pin RDIMMs using major OEM Samsung, Micron or Hynix chips. Installation must follow the motherboard manual for supported capacities and approved DIMM population order to ensure proper operation. Buyers needing UDIMM or SODIMM form factors cannot use this kit.

Questions about this item

How much power does the 1.1 V DDR5 RDIMM kit draw when the server runs continuously?

Each module operates at 1.10 V; the registered design reduces electrical load on the memory controller so all four slots can stay populated at the rated 4800 MT/s speed.

What motherboard slot and memory type are required for this 288-pin RDIMM kit to function?

The kit needs a Supermicro H14DSH motherboard with DDR5 RDIMM slots; it will not fit UDIMM or SODIMM sockets.

Will these CL40 4800 MT/s modules run at their rated speed alongside slower DDR5 RDIMMs already installed in the same system?

The memory controller typically clocks all populated slots to the slowest module's speed, so mixing with slower DDR5 RDIMMs will reduce overall performance.
