Exact-match DDR5-4800 ECC RDIMM kit

This NEMIX RAM kit supplies 256GB across four 64GB modules built to the DDR5-4800 (PC5-38400) JEDEC standard with CL40 latency and 1.10V operation. Each 288-pin Registered DIMM uses a 2Rx4 organization with on-die ECC, matching the Supermicro H14SSL-NT motherboard's memory-controller expectations for full-capacity recognition at rated speed. It is not intended for consumer desktop boards that require unbuffered UDIMMs or lower-density modules.

Sustained-load stability under full population

Registered buffering offloads the memory controller so all four slots can run fully populated at the rated 4800MT/s without down-clocking, while ECC corrects single-bit errors on the fly to prevent silent data corruption during long compute runs. The 1.10V JEDEC voltage keeps power draw predictable across continuous workloads. Buyers who need higher transfer rates or lower CAS latencies than the DDR5-4800 CL40 specification will not find them in this kit.

Straightforward server installation

The 288-pin RDIMM form factor seats directly into the H14SSL-NT DIMM slots; no heat spreaders are present, so clearance is minimal. Because server memory population order is board-specific, the system manual must be consulted for the approved slot sequence before installation — incorrect ordering is the most common cause of a no-post condition. Mixing these modules with different ranks, voltages, or speeds is not supported.

Domande su questo articolo

How much power do four 1.10 V DDR5-4800 2Rx4 RDIMMs draw under sustained load?

Each module runs at 1.10 V and DDR5-4800 speed; total power depends on workload and the Supermicro H14SSL-NT memory controller, but registered architecture offloads the controller so all four slots can stay fully populated at rated speed.

What motherboard slot type and memory population rules does this kit require?

The kit uses 288-pin DDR5 RDIMM form factor and is verified for the Supermicro H14SSL-NT; consult that board's manual for supported capacities and the approved DIMM installation order.

Will these CL40 2Rx4 registered ECC RDIMMs run at DDR5-4800 alongside slower DDR5 modules already installed in the same server?

The memory controller typically clocks all populated slots to the lowest common speed, so mixing with slower DDR5 RDIMMs would drop the kit from its rated 4800 MT/s to the slower module's speed.
