Server ECC RDIMM for registered workloads

This 32GB DDR4 module uses registered ECC circuitry to deliver error-corrected memory for Supermicro platforms. It targets administrators who need single-module density in a 288-pin form factor. The Micron chipset runs at 1.20V standard voltage.

PC4-21300 bandwidth ceiling

The DDR4 2666 interface caps throughput at PC4-21300, so sustained transfer rates cannot exceed that ceiling. CL19 latency adds fixed cycle delay on every access. Registered buffering consumes one clock cycle, which is mandatory for signal integrity on multi-module channels.

32GB single-module headroom

A single 2Rx4 rank layout provides 32GB capacity, letting a server populate fewer slots for the same total memory. Workloads that exceed 32GB per channel will require additional modules. The dual-rank organisation helps interleave but does not increase per-module density beyond 32GB.

Questions about this item

Should I choose the 32GB 2Rx4 RDIMM or look for a different capacity?

This module provides 32GB in a single 2Rx4 registered DIMM. Select it when your server requires a 32GB registered ECC stick at 2666MHz.

What does the 2666MHz rating mean once the module is installed?

The memory runs at 2666MHz with CL19 latency at 1.2V, delivering PC4-21300 bandwidth for supported server platforms.

How does the DDR4 RDIMM interface limit performance in practice?

The 288-pin registered DDR4 interface caps speed at 2666MHz and requires a motherboard that supports registered ECC DIMMs.
