32 GB DDR4-3200 ECC registered RDIMM for HPE-compatible servers, 2Rx8 at 1.2 V
This is a 32GB DDR4-3200 registered DIMM built for servers that require ECC protection and registered signalling. It fits 288-pin DDR4 slots and operates at 1.2V with a 2Rx8 organisation. Buyers needing unbuffered UDIMMs or non-ECC memory for consumer boards cannot use this module.
The module runs at the standard DDR4-3200 data rate (PC4-25600) with a CAS latency defined by the JEDEC specification for this speed grade. Registered buffering adds one clock cycle of address-command delay, which the memory controller must support. Systems limited to lower DDR4 speeds will downclock the module automatically.
It replaces lower-capacity registered ECC DIMMs such as 16GB or 8GB modules to increase total memory per channel. The jump is worthwhile when the workload exceeds the current memory ceiling or when matching ranks across channels for optimal bandwidth. Servers that only accept unbuffered memory or lack registered DIMM support cannot take this upgrade.

This module provides 32GB in a single 2Rx8 registered DIMM; select the quantity that matches your platform's maximum supported capacity and channel population rules.
The module runs at 3200 MT/s with a peak transfer rate of 25600 MB/s, and the memory controller will operate it at the highest speed the CPU and platform allow.
The 288-pin DDR4 form factor fits standard DDR4 server slots, while the registered buffer reduces electrical load on the memory controller to support higher total capacities.
