Server Memory Kit

This NEMIX RAM kit provides 512GB of DDR5 server memory across sixteen 32GB registered DIMMs. It is built for IT professionals managing mission-critical workloads on compatible Dell PowerEdge platforms. The modules deliver ECC error correction and registered buffering for data integrity in enterprise environments.

DDR5 4800 Interface Limits

The DDR5 4800 standard (PC5-38400) sets the maximum transfer rate and timing envelope these modules operate within. CAS latency is fixed at CL40 and voltage at 1.10V, so performance cannot exceed the JEDEC baseline for this speed grade. Registered signalling adds a cycle of command delay compared to unbuffered designs.

Pre-Installation Checks

Verify that your motherboard supports 288-pin DDR5 RDIMMs with 2Rx4 organisation and can address the full 512GB capacity across all populated slots. Confirm the system BIOS is current enough to initialise sixteen registered modules at the rated speed. Buyers needing unbuffered UDIMMs or a lower total capacity should select a different kit.

Preguntas sobre este artículo

Should I choose the 512GB kit with 16 modules of 32GB or a smaller capacity for my Dell PowerEdge R860?

The kit provides 512GB total using 16 modules of 32GB each; select it when your workload needs that full capacity and your server has enough DIMM slots to populate all 16 positions.

What does the DDR5 4800 CL40 rating deliver once the modules are installed in the server?

The modules run at 4800 MT/s with a CAS latency of 40 cycles, giving a PC5-38400 peak bandwidth that the memory controller will use for registered ECC workloads.

How does the 288-pin DDR5 RDIMM interface limit performance in practice?

The 288-pin registered DDR5 form factor caps the kit at the JEDEC 4800 MT/s standard speed and 1.10V operation, so the server cannot exceed that data rate without overclocking support.
