32GB DDR5 ECC UDIMM for servers

This 32GB DDR5 4800 module adds error-correcting memory to compatible server platforms. It targets administrators who need data integrity for critical workloads without registered buffering. The unbuffered design suits systems that accept UDIMM ECC rather than RDIMM.

288-pin DDR5 slot requirement

Installation requires a motherboard with DDR5 UDIMM slots and ECC support in the BIOS. The module runs at the standard 1.1V DDR5 voltage and uses a 2Rx8 organisation. It frees no additional slots beyond the single DIMM occupied and adds no heat spreader to the build.

Sustained load with ECC overhead

Under continuous operation the ECC logic corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The CAS latency of 40 cycles applies at the rated 4800 MT/s speed. Without a heat spreader, airflow across the bare PCB becomes the primary thermal path during extended sessions.

Questions sur cet article

How does the CAS latency of 40 affect sustained throughput on this DDR5 4800 module?

The CL40 timing at 4800 MT/s sets the minimum cycle delay; under continuous load the memory controller cannot issue new commands faster than this latency allows, making it the first bottleneck for sustained bandwidth.

What thermal or acoustic impact should I expect when this unbuffered ECC UDIMM runs at 1.10 V all day?

With no heat spreader and standard 1.10 V DDR5 voltage, the module relies on case airflow; it generates modest heat and zero fan noise of its own, so temperatures stay within normal DDR5 limits in a ventilated chassis.

Which motherboard feature must my system already provide for this 288-pin DDR5 ECC UDIMM to function?

The board needs a DDR5 UDIMM slot with on-die ECC support and an unbuffered memory controller; registered or RDIMM-only platforms will not accept this 2Rx8 module.
