Capacity and architecture

This 32 GB DDR5 module is an unbuffered ECC DIMM built for servers and workstations that need error correction without registered signalling. It uses a 2Rx8 organisation based on sixteen-gigabit components and runs at the standard 4800 MT/s data rate.

Speed and timing

The SPD is programmed to JEDEC standard DDR5-4800 timings of 40-39-39 at 1.10 V, delivering PC5-38400 bandwidth out of the box. No overclocking or manual tuning is required to reach the rated frequency and latency.

Fit and alternatives

This suits builders populating platforms that accept 288-pin unbuffered ECC DDR5 and want single-module 32 GB density. Buyers who need registered DIMMs, lower latency bins, higher frequencies or non-ECC memory should look at other modules.

Questions about this item

Will the ECC feature on this 32GB DDR5 module require any special maintenance or replacement over time?

ECC is a built-in function of the memory chips and does not need separate maintenance or scheduled replacement; the module itself is a solid-state component with no moving parts to service.

What is the first limit reached when this DDR5 4800 CL40 module runs under sustained heavy load?

The primary limit is the JEDEC-standard 40-39-39 timing at 1.1V; sustained operation stays within this validated latency and voltage envelope.

How much heat and power does this 1.1V unbuffered DDR5 DIMM produce when running all day in a server?

Operating at 1.1V, the module draws low power for DDR5; heat output is modest and managed by standard server airflow, with no active cooling required on the DIMM itself.
