Server Memory Upgrade

This NEMIX RAM module provides 8 GB of DDR4 ECC registered memory for server platforms that require DDR4 2933 MHz PC4-23400. The single-rank 1Rx8 organisation and 1.2 V operation suit systems built for registered DIMMs. It is not compatible with standard desktop or laptop motherboards that accept only unbuffered memory.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller, helping stability when all slots are populated under continuous workloads. ECC circuitry detects and corrects single-bit errors during extended operation. CAS latency of 21 cycles at the rated 2933 MHz data rate defines the timing profile for sustained throughput.

Build And Connectors

The 288-pin RDIMM form factor fits server DIMM sockets keyed for registered DDR4 modules. Major OEM chips from Samsung Micron or Hynix are assembled on a standard-height PCB. The registered design means this module must be installed in platforms that explicitly support registered memory.

Questions about this item

At 1.2V and CAS 21, does the 2933MHz registered DIMM run cooler than higher-voltage server memory during continuous operation?

The module operates at the standard DDR4 server voltage of 1.2V, which helps limit heat output during sustained workloads compared to higher-voltage alternatives.

Must my server motherboard have RDIMM slots and support ECC registered DDR4 to use this kit?

Yes, the module is a 288-pin ECC registered DIMM and requires a server platform that accepts registered DDR4 memory with error correction.

Can I mix this 1Rx8 PC4-23400 stick with other DDR4 ECC RDIMMs of different speeds or ranks in the same server?

Mixing ranks or speeds is possible on many platforms, but the system will run all modules at the lowest common speed and may require specific population rules; consult your server manual.
