A-Tech Supermicro Certified 64GB DDR4 2933MHz ECC RDIMM Server RAM

Certified 64GB DDR4 2933MHz ECC RDIMM

This Supermicro-certified module delivers 64GB of DDR4 memory at 2933MHz with CL21 latency. It uses Samsung chips in a 2Rx4 registered ECC configuration operating at 1.20V. The 288-pin RDIMM form factor is designed for server platforms that require registered memory with error correction.

Sustained load behaviour

Registered buffering and ECC circuitry maintain data integrity during continuous workloads by correcting single-bit errors and reducing electrical load on the memory controller. Dual-rank organisation allows the controller to interleave accesses across ranks, helping sustain throughput when all 64GB are actively addressed for extended periods.

DDR4 interface limits

The DDR4 2933 standard caps transfer rates at 23400 MB/s per module, so aggregate bandwidth scales linearly with the number of populated channels. Registered DIMMs add one clock cycle of address/command delay, which the memory controller must account for in timing parameters. Total capacity is bound by the platform's maximum supported rank count per channel.
