Brute Networks 64GB DDR4-2666 4Rx4 ECC LRDIMM 1.2V CL15 288-Pin

64GB DDR4 LRDIMM for Dell Servers

This 64GB DDR4-2666 LRDIMM uses a 4Rx4 organisation and registered ECC design to deliver high-density memory for compatible Dell platforms. It operates at 1.2V with a CAS latency of 15 and conforms to the PC4-21300 standard. The module is built with major-brand DRAM chips and matches Dell part number 4JMGM.

Sustained Load Behaviour

Under continuous workloads the registered buffer reduces electrical load on the memory controller, allowing the 4Rx4 configuration to maintain stability at the rated 2666 MT/s data rate. ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long-running virtualisation or database tasks. The 1.2V operating voltage keeps power draw predictable across extended periods.

DDR4 Interface Limits

The DDR4 interface caps the module at 2666 MT/s and the PC4-21300 bandwidth ceiling, so faster speeds or lower latencies are not available within this generation. Four-rank density limits the number of modules the memory controller can address per channel, restricting total system capacity compared to dual-rank alternatives. Compatibility is limited to systems qualified for this specific LRDIMM specification.
