Brute Networks
32GB DDR4-3200 ECC registered RDIMM with 1Rx4 organisation for compatible HPE servers
This Brute Networks module provides 32GB of DDR4-3200 registered ECC memory in a 1Rx4 configuration. It is built as a direct equivalent to HPE part number P41682-001 and carries 100 percent HPE compatibility. The RDIMM form factor suits enterprise servers that require registered, error-correcting DIMMs for stable operation.
As a standard DDR4 RDIMM the module runs at the JEDEC-defined 1.2 V and draws only the power required for its 3200 MT/s data rate. Registered buffering reduces electrical load on the memory controller, helping keep system thermals predictable during sustained workloads. No active cooling is present on the DIMM itself; airflow from the server chassis is sufficient for normal operating temperatures.
The single-rank 1Rx4 layout leaves additional DIMM slots free for future capacity expansion within the same memory channel. ECC registration offloads error detection from the CPU, freeing processor cycles for application work. Installation follows standard RDIMM keying; the module fits any qualified HPE server slot that accepts PC4-25600 registered memory.

Power down the server, open the chassis, align the notch on the 1Rx4 module with the DDR4 slot key, press firmly until both ejector tabs click, then populate slots per the server manual — typically one DIMM per channel first for maximum bandwidth.
The module itself has no moving parts and requires no scheduled maintenance; replacement is only needed if a correctable error count exceeds the platform threshold or a hard failure is logged by the system.
The DDR4-3200 data rate and 1Rx4 organisation cap sustained throughput at the rated 25600 MB/s per module; thermal throttling or rank-level bandwidth saturation will occur before any higher speed can be reached.
