A-Tech 64GB DDR4 2933 ECC LRDIMM 4Rx4 CL21 1.20V Server RAM

64 GB DDR4 2933 ECC LRDIMM module

This 64 GB DDR4 2933 ECC LRDIMM module uses Load Reduced technology with a 4Rx4 organisation to deliver high-capacity memory for server and workstation platforms. It operates at the standard 1.20 V DDR4 voltage and carries a CL21 latency rating. The 288-pin DIMM form factor fits compatible DDR4 slots in enterprise systems.

Sustained load behaviour with Load Reduced design

The Load Reduced buffer reduces electrical loading on the memory bus, allowing the module to maintain signal integrity when all ranks are active during prolonged workloads. ECC circuitry detects and corrects single-bit errors throughout continuous operation. The 4Rx4 rank structure distributes access across four ranks, supporting steady throughput in multi-threaded server applications.

DDR4 2933 interface practical limits

The DDR4 2933 (PC4-23400) interface caps peak bandwidth at the rated data rate, so sustained throughput cannot exceed this ceiling regardless of rank count. The 288-pin DIMM slot provides the physical and electrical connection defined by the DDR4 standard. System memory controllers must support ECC LRDIMM operation at 2933 MT/s to utilise the full specification.
