Server Memory Upgrade

This 32GB DDR4 ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It matches the specifications of Kingston part KVR21R15D4/32 and operates at 2133MHz with CL15 latency at 1.2V.

Installation Notes

The 288-pin module installs in standard DDR4 RDIMM slots, but it will not work in desktop or consumer motherboards that accept only unbuffered memory. Mixing registered and unbuffered modules prevents the system from booting, so verify the platform supports registered ECC before purchase.

Key Specification

Capacity is 32GB in a dual-rank 2Rx4 configuration running at PC4-17000 speed. This single figure determines whether the module fits the memory population rules and maximum per-slot limit of your qualified server or workstation.
