32 GB DDR5 ECC module for workstations and servers

This single 32 GB DDR5 4800 UDIMM adds error-correcting memory to compatible workstations, servers and NAS systems. The unbuffered design fits standard 288-pin desktop slots while the ECC function helps maintain data integrity under heavy workloads.

Low-voltage operation at 1.1 V with no heat spreader

Running at the JEDEC-standard 1.1 V keeps power draw modest and thermals manageable in densely populated memory bays. The bare PCB design avoids extra height, allowing tighter DIMM spacing without restricting airflow from case fans.

Fits standard 288-pin DDR5 slots in desktops

No additional cooling hardware or proprietary connectors are required; the module installs like any consumer UDIMM. The 32 GB capacity per slot frees remaining channels for further expansion while supporting ECC workloads such as ZFS, virtualization and scientific computing.

Questions about this item

How do I install the 288-pin DDR5 ECC UDIMM in my workstation?

Align the notch on the module with the slot key, press down firmly until both retention clips click, then verify the system detects 32 GB at 4800 MT/s in BIOS.

What maintenance will this 1.1 V ECC module need over time?

No routine maintenance is required; run a memory diagnostic if you see corrected ECC errors in system logs and replace the stick only if errors persist.

What limit appears first when this CL40 2Rx8 module runs sustained workloads?

The CAS latency of 40 cycles at 4800 MT/s sets the response-time floor before bandwidth or thermal limits become a factor.
