Brute Networks 64GB DDR4-2400 PC4-19200 4Rx4 ECC LRDIMM 1.2V CL15

64GB DDR4-2400 LRDIMM for Lenovo servers

This 64GB DDR4-2400 PC4-19200 module uses a 288-pin LRDIMM form factor with 4Rx4 organisation. It operates at 1.20V with a CAS latency of CL15 and includes ECC error correction. The load-reduced design places less electrical load on the memory bus than standard registered DIMMs. It is built with major-brand DRAM chips and matches Lenovo part number 4X70G88321.

Replaces lower-capacity DDR4 LRDIMMs

Upgrading makes sense when your Lenovo server runs near its memory ceiling and swapping or paging slows virtual machines or databases. Adding these 64GB modules lets you maximise the installed capacity supported by the platform without replacing the host. The jump is worth it when application responsiveness is limited by physical RAM rather than by CPU or storage throughput.

Sustained load behaviour

The load-reduced buffer reduces electrical loading on the memory controller during continuous read and write streams. This helps maintain signal integrity at the rated 2400 MT/s speed when all channels are populated. ECC corrects single-bit errors in real time, preventing data corruption during long-running workloads. The 1.20V operation keeps power draw steady under sustained utilisation.
