32GB DDR4 ECC LRDIMM for ASUS servers

This 32GB DDR4 2666 ECC LRDIMM module is built for ASUS server motherboards that require load-reduced registered memory. It operates at 1.2V with CL19 latency and a 2Rx4 rank structure. The 288-pin form factor fits standard DDR4 server slots. IT professionals select this specification for mission-critical workloads demanding stability.

Upgrade from non-ECC or standard RDIMM

Systems running unbuffered or standard registered DIMMs without load reduction can move to this LRDIMM to support higher per-slot density. The jump is worth it when the motherboard qualifies LRDIMM and the workload needs more capacity per channel than RDIMM allows. Compatibility is limited to platforms that explicitly list LRDIMM support in their qualified vendor list.

32GB per module scales to 256GB per slot

Each module provides 32GB; populated across eight slots the platform reaches 256GB per channel. Headroom covers virtualisation hosts, in-memory databases and large dataset caching. Capacity runs out when the application working set exceeds the total installed memory or when the memory controller limits rank count per channel.

Questions about this item

Will the 288-pin DDR4 LRDIMM fit my ASUS server motherboard?

The module uses the standard 288-pin DDR4 LRDIMM form factor designed for ASUS server motherboards that support load-reduced memory.

Do I need to configure anything in the BIOS after installing this ECC LRDIMM?

Install the module with the system powered off; most ASUS server boards detect the 2666 MT/s CL19 2Rx4 timings automatically, but verify the memory mode matches your platform requirements.

How do I know when this 32 GB module should be replaced?

ECC corrects single-bit errors on the fly; if the system logs uncorrectable errors or the module fails memory diagnostics, plan a replacement.
