Brute Networks 64GB DDR5-4800 2Rx4 ECC RDIMM 4X77A77033-BN

Lenovo-compatible 64GB DDR5-4800 RDIMM

This module is a 64GB PC5-38400 DDR5-4800 2Rx4 ECC registered RDIMM built to match Lenovo part number 4X77A77033. It delivers 4800 MT/s throughput with on-die ECC for data integrity in server workloads. Brute Networks supplies it as a 100% compatible third-party alternative with a lifetime warranty. The dual-rank x4 organisation suits high-capacity configurations.

For servers needing registered ECC DDR5 at 4800 MT/s

The part fits Lenovo platforms qualified for the 4X77A77033 reference and other systems that accept registered DDR5 RDIMMs with 2Rx4 layout. It is not for machines that require unbuffered UDIMMs or non-ECC memory, nor for boards that cannot address 64GB per slot. Buyers needing different speeds, ranks or voltages should verify their platform documentation before ordering.

Registered DDR5 RDIMM with 2Rx4 organisation

The registered buffer and 2Rx4 rank structure are the decisive attributes; they determine whether the memory controller can initialise the module at 4800 MT/s. Systems designed for unbuffered or single-rank DIMMs will not post with this part. Confirm the motherboard qualification list for 4X77A77033 or an equivalent 64GB DDR5-4800 2Rx4 RDIMM before purchase.
