ASUS Server ECC LRDIMM Upgrade

This NEMIX RAM module is a 32GB DDR4 2666 PC4-21300 ECC LRDIMM built for ASUS server motherboards. It targets administrators expanding memory in compatible enterprise platforms. The single-stick design suits slots that accept load-reduced registered DIMMs.

Load-Reduced Registered Architecture

The decisive specification is the load-reduced registered (LRDIMM) buffer, which reduces electrical load on the memory bus so higher capacities can be populated per channel. Standard RDIMM or unbuffered modules will not function in slots that require this signalling.

32GB Capacity with 2Rx4 Organisation

One 32GB stick uses a 2Rx4 layout at 1.2V and CL19 latency, providing substantial headroom for virtualisation, database caching and large dataset workloads. Systems needing more than the maximum supported DIMM count per CPU will hit the platform limit before the module itself becomes a bottleneck.

Questions about this item

What does the 2666 speed rating mean once the module is installed in a compatible ASUS server?

The module operates at DDR4 2666 with CL19 latency, providing 2666 MT/s data transfer in a supported ASUS server platform.

How does the DDR4 2666 PC4-21300 interface cap real-world throughput?

The PC4-21300 designation indicates the standard DDR4 2666 data rate; actual throughput depends on the server memory controller and channel configuration.

What physical slot and clearance does the 288-pin LRDIMM need to fit?

The 288-pin DDR4 LRDIMM fits a standard DDR4 DIMM slot; the module has no heat spreader, so it requires only the slot's vertical clearance.
