Server Memory Upgrade

This NEMIX RAM module provides 32GB of DDR5 server memory operating at 4800MHz with a PC5-38400 rating. It uses a 288-pin ECC RDIMM form factor with registered buffering and a 2Rx8 rank configuration. The module runs at 1.1V and carries a CAS latency of 40. It is built with major OEM chips from Samsung, Micron or Hynix.

Registered ECC Design

The registered buffer reduces electrical load on the memory controller, allowing higher module counts in multi-socket servers. On-die ECC detects and corrects single-bit errors to protect data integrity in critical workloads. The 2Rx8 organisation balances density and signal integrity for stable operation at the rated 4800MHz speed. These hardware traits replace the need for software-based error mitigation.

For DDR5 Server Platforms

This kit suits administrators upgrading or repairing DDR5-compatible server platforms that require registered ECC DIMMs. It will not fit desktop motherboards that accept only unbuffered non-ECC UDIMMs. Builders needing different capacities, speeds or rank configurations should select modules matching their platform's qualified vendor list.

Questions about this item

What is the expected lifespan of the Samsung Micron Hynix DRAM chips on this ECC RDIMM before replacement?

The module uses major OEM Samsung Micron Hynix DRAM chips and carries a lifetime replacement warranty from NEMIX RAM.

Which electrical limit is reached first when this DDR5 4800 registered DIMM runs sustained workloads?

The 1.1V operating voltage and registered buffer design set the primary electrical limits during continuous operation.

How much extra heat does this 288-pin 2Rx8 module generate inside a server running all day?

At 1.1V the 32GB DDR5 4800 RDIMM produces typical registered DIMM heat levels; server airflow handles the thermal load.
