NEMIX RAM 128GB (4x32GB) DDR5 5600 CL46 1.1V 288-pin UDIMM memory upgrade for SuperMicro SYS-531AD-I C9Z790-CG

128 GB DDR5 kit for SuperMicro workstation

This 128 GB kit contains four 32 GB DDR5 5600 UDIMM modules built for the SuperMicro SYS-531AD-I C9Z790-CG system. It targets professionals who need high-capacity, non-ECC memory for compute-intensive workloads on this specific platform. The 2Rx8 organisation and 1.10 V operation match the workstation's validated memory profile. Installation follows standard UDIMM procedures for desktop and workstation boards.

2Rx8 organisation and validated compatibility

Each module uses a 2Rx8 configuration with CL46 latency at the DDR5 5600 (PC5-44800) data rate. The kit is assembled from major OEM Samsung, Micron or Hynix components and stress-tested for the target SuperMicro platform. No heat spreaders are fitted, so airflow in the chassis must handle module cooling. The package supplies only the four UDIMMs; no additional software, cables or brackets are included.

DDR5 UDIMM limits for this platform

The DDR5 5600 UDIMM standard used here tops out at the 5600 MT/s JEDEC speed with CL46 timing and 1.10 V. Higher data rates, lower latencies or ECC functionality are not supported by these modules. Builders who need registered DIMMs, ECC error correction or speeds beyond PC5-44800 must select a different memory type. The 288-pin UDIMM form factor also prevents use in systems that require RDIMM or SO-DIMM modules.
