32GB DDR5 desktop module

This 32GB DDR5 module plugs into a standard 288-pin DIMM slot and runs at 5600 MT/s with a CAS latency of CL40. It is intended for desktop builders who want a single high-capacity stick for workstations or gaming rigs. The black heatspreader carries no RGB lighting.

Thermals and power at stock settings

Operating at 1.25 V, the module draws modest power and runs cool enough for typical chassis airflow. On-die ECC helps maintain data integrity without adding audible noise. No fan or liquid cooling is required for normal operation.

Intel XMP 3.0 profile support

The kit includes an Intel XMP 3.0 profile that sets 5600 MT/s and CL40 timings automatically when enabled in the BIOS. This single specification determines whether the rated speed is reached without manual tuning.
