32GB DDR5 4800 ECC UDIMM

This 32GB DDR5 module runs at 4800 MT/s with CL40 timings of 40-39-39 and operates at 1.10V. It is an unbuffered ECC UDIMM built with a 2Rx8 dual-rank layout. The part is engineered for cost-effective performance in workstations and entry-level servers.

Workstations and entry servers needing ECC

Suits builders who want error-correcting memory for office applications, digital media design, video editing or hosting web content without registered DIMM support. Not for platforms that require registered or load-reduced modules, or for systems limited to lower-density single-rank UDIMMs.

32GB single-module capacity

One module provides 32GB of addressable memory, giving headroom for multi-tasking workloads and moderate virtualization. Capacity runs out when the board's maximum UDIMM limit is reached or when registered memory is required for larger configurations.

Questions about this item

Does my motherboard need to accept DDR5 4800 UDIMMs with ECC for this 32 GB module to function?

Yes — this module is a DDR5 4800 ECC UDIMM, so the board must support DDR5, the UDIMM form factor, and ECC operation.

Can I add this 2Rx8 CL40 stick to an existing bank of CL40 DDR5 4800 ECC UDIMMs?

Yes — matching speed, latency, rank, and ECC type allows it to run alongside identical modules.

How do I confirm the module runs at 4800 MT/s with 40-39-39 timings after installation?

Check the memory speed and timings in BIOS/UEFI or a system-information tool; they should read 4800 MT/s and 40-39-39.
