Server DDR4 DIMM for entry-level HPE platforms

This 32 GB DDR4 module is built for entry-level HPE servers that require unbuffered memory. It suits administrators who need a single high-capacity stick to expand or replace system RAM without registered buffering.

Dual-rank 3200 MHz CL22 specification

The module runs at 3200 MHz with PC4-25600 bandwidth and a CAS latency of 22. Its dual-rank organisation provides the density and timing profile that the platform expects for stable operation.

Standard-voltage DDR4 thermals and power

Operating at the standard DDR4 voltage, the unbuffered DIMM generates typical heat for a 3200 MHz part and does not require active cooling beyond normal server airflow. Power draw remains within the normal envelope for dual-rank DDR4 memory.
