Capacity & Fit

This 32 GB DDR5 module replaces Kingston KVR48U40BD8-32 and the KVR48U40BD8K2-64 kit. It is built for desktop systems that accept 288-pin unbuffered DIMMs and runs at the standard 1.10 V. The single stick lets you add capacity without filling every slot.

Build & Daily Use

Major-brand chips are used throughout and every unit passes quality-assurance testing before it ships. The unbuffered design means the module plugs straight into a standard desktop DDR5 socket with no extra registration step. Installation follows the usual DIMM procedure and requires no special tools or configuration.

Deciding Specification

The tested frequency is 4800 MT/s with a CAS latency of CL40, giving a PC5-38400 data rate. If your motherboard and CPU support DDR5 4800 at that latency, the module will operate at its rated speed; otherwise it will downclock to the highest mutually supported setting.
