NEMIX RAM 128GB DDR5 4800 ECC RDIMM

This registered server memory module provides 128GB of DDR5 capacity in a single 288-pin DIMM. It operates at 4800MHz with CL40 latency and a low 1.1V voltage. The module features ECC error correction and 4Rx4 organisation for data integrity in critical workloads. It is validated for compatibility with ASRock TRX50 WS workstation motherboards.

Suited for ASRock TRX50 WS memory expansion

This module targets administrators upgrading or populating ASRock TRX50 WS workstations that require registered ECC memory. The single-stick 128GB density maximises capacity per slot. Builders needing non-ECC unbuffered memory for consumer platforms cannot use this registered DIMM. Systems requiring lower-density modules or different form factors should look elsewhere.

128GB single-module DDR5 density

The defining specification is the 128GB capacity delivered in one 288-pin RDIMM. This density allows large memory configurations within limited slot counts on the target motherboard. The 4Rx4 architecture supports this high capacity at the rated 4800MHz speed. Verify that the workstation memory controller supports 4Rx4 registered modules at this density before purchase.
