32GB DDR5 4800 ECC UDIMM for SuperMicro

This is a 32GB DDR5 4800 CL40 ECC unbuffered UDIMM built for SuperMicro servers and workstations. The single-rank 2Rx8 module runs at 1.10V and uses major OEM chips from Samsung, Micron or Hynix. It carries the SuperMicro MEM-DR532L-CL01-EU48 compatibility listing and installs in a standard 288-pin DDR5 slot. No heat spreader is fitted.

Suits SuperMicro DDR5 platforms needing ECC

IT teams maintaining SuperMicro systems that require DDR5 ECC unbuffered memory at 4800 MT/s will find this module validated for those boards. Builders using consumer motherboards, registered DIMM slots, or non-ECC platforms should look elsewhere because the pinout, signalling and error-correction behaviour differ. The lack of a heat spreader also means it is not aimed at heavily overclocked enthusiast builds.

Check your board accepts DDR5 ECC UDIMM

Before ordering, confirm the motherboard manual lists DDR5 4800 ECC unbuffered UDIMM support and that the CPU memory controller is rated for 1.10V operation. Verify the slot count and maximum capacity per channel so the single 32GB module fits the planned configuration. Ensure the BIOS version in use recognises 2Rx8 density modules without requiring a microcode update.

Questions about this item

Does my Supermicro motherboard need 288-pin DDR5 ECC UDIMM slots to accept this 32 GB module?

Yes — the stick is a 288-pin DDR5 ECC UDIMM, so the board must provide DDR5 UDIMM sockets that support ECC.

Can I keep my existing DDR5 4800 CL40 ECC UDIMMs and add this 2Rx8 32 GB module alongside them?

It will work if the motherboard accepts mixed ranks and the total capacity stays within the board's limit; match speed, voltage and ECC type for best stability.

How do I confirm the module is running at 4800 MT/s with CL40 after installation?

Check the BIOS memory information or a tool such as CPU-Z — it should report DDR5-4800, 1.1 V, CL40 and ECC active.
