  • 32 GB capacity expands workstation memory for heavy multitasking
  • DDR5 4800 speed delivers high bandwidth for demanding workloads
  • CL40 latency supports responsive data access
  • 1 V operation reduces power draw and heat
  • 288-pin UDIMM fits Supermicro SYS-531AD-I and C9Z790-CG systems

System-Specific DDR5 Upgrade

This 32GB DDR5 module is built for the SuperMicro SYS-531AD-I and C9Z790-CG platforms. It targets IT professionals and workstation builders who need validated, non-ECC memory for those exact systems.

Compatibility Check

Verify that your motherboard accepts DDR5 4800 non-ECC unbuffered UDIMMs and has a free 288-pin slot. The module runs at 1.10V with CL40 latency and a 2Rx8 organisation, so the board must support those electrical and timing parameters.

Build and Daily Use

Major OEM Samsung, Micron or Hynix chips are assembled without a heat spreader, keeping the profile low for dense workstation chassis. The standard 288-pin DDR5 keying prevents mis-insertion, and the single-stick 32GB density simplifies future capacity expansion.

Questions about this item

Does the NEMIX RAM 32GB DDR5 4800 CL40 UDIMM arrive as a single stick or a kit?

The module ships as one 32 GB stick (1X32GB). No extra memory is included.

Is the 4800 MT/s CL40 2Rx8 version the only option for this SuperMicro system?

This part number MD38400-328K1 is built for the SYS-531AD-I and C9Z790-CG at 4800 MT/s CL40 2Rx8. Other speeds or ranks are separate part numbers.

Will the 4800 MT/s rating run at that speed on the C9Z790-CG without manual tuning?

The UDIMM is JEDEC-standard DDR5-4800 1.10 V CL40, so the motherboard will configure it automatically at 4800 MT/s.
