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.

Questions sur cet article

How much heat and power does a 64GB 1.20V DDR4 2933 LRDIMM add when running all day?

The module operates at standard DDR4 1.20V with Load Reduced buffering, which lowers electrical load on the memory bus and helps keep thermals manageable during continuous server workloads.

What motherboard slot and memory-channel support are needed to install this 288-pin ECC LRDIMM?

A DDR4 DIMM slot with 288 pins and a server or workstation platform that supports ECC Load Reduced DIMMs and 4Rx4 organisation is required for the module to function.

Can this 4Rx4 PC4-23400 stick share a channel with lower-ranked DDR4 ECC modules?

Mixing 4Rx4 Load Reduced DIMMs with different rank or buffer types on the same channel is not supported by DDR4 server memory architecture; populate identical modules per channel for stable operation.
