Brute Networks 32GB DDR4-3200 1Rx4 ECC RDIMM P43789-B21

HPE-Compatible 32GB DDR4-3200 RDIMM

This 32GB DDR4-3200 ECC registered DIMM is built for HPE server platforms requiring P43789-B21 compatibility. It targets administrators upgrading memory capacity in supported enterprise systems. The module uses a 1Rx4 organisation with major-brand components. It is not suited for desktop boards that cannot address registered ECC memory.

PC4-25600 Speed and Registered Design Limits

The DDR4-3200 interface delivers a 25600 MB/s peak transfer rate within the JEDEC standard for this data rate. Registered buffering adds one clock cycle of latency versus unbuffered modules, which the memory controller must support. ECC operation requires a platform that enables error correction in the BIOS or firmware. Systems limited to lower DDR4 speeds or unbuffered DIMMs cannot use this module.

1Rx4 Rank Determines Slot Population Rules

The single-rank 1Rx4 layout means each module places one electrical load per channel, allowing higher total capacity per channel compared to dual-rank alternatives. Platform-specific population rules still dictate the maximum number of ranks per channel and the supported slot order. Buyers must verify their server's qualified vendor list and rank limits before purchase.
