Brute Networks 16GB DDR4-3200 2Rx8 ECC UDIMM server RAM

What this module is

Brute Networks 16GB DDR4-3200 ECC UDIMM is built for servers and workstations that require error-correcting memory. It replaces Lenovo part 4X77A77495 with a compatible 16 GB stick. The module runs at PC4-25600 speed and uses a major-brand chipset. Buyers who need non-ECC memory for a desktop board should look elsewhere.

Deciding specification

The module is organised as 2Rx8 dual-rank, not single-rank as some listings state. This rank structure determines whether the memory controller can populate all slots at full speed. Systems that only support single-rank DIMMs in certain configurations will not run this module at its rated 3200 MT/s.

Build integration

The UDIMM form factor fits standard unbuffered DDR4 slots in compatible Lenovo servers. ECC functionality requires a platform that enables error correction in the BIOS. The stick frees a second slot for another 16 GB module to reach 32 GB per channel. Builders needing registered or load-reduced DIMMs cannot use this part.
