OWC 128GB DDR4 2933 PC4-23400 CL21 8Rx4 288-pin 1.2V ECC Registered RDIMM for ASUS GPU Server ESC8000 G4

Server-Specific 128GB ECC RDIMM

This 128GB DDR4 ECC Registered DIMM is built for the ASUS GPU Server ESC8000 G4 and compatible ASRock server motherboards. It targets administrators who need high-capacity, error-correcting memory for virtualization, GPU compute or database workloads. The module operates at 1.2V and conforms to JEDEC PC4-23400 standards. It will not work in standard desktop PCs or alongside unbuffered or load-reduced DIMMs.

Keyed 288-Pin Installation Constraints

The 288-pin RDIMM fits only server boards that support registered ECC memory and 8Rx4 rank configuration. Because it lacks a heat spreader, airflow across the module must be maintained by the chassis fans. Mixing this stick with unbuffered or ECC load-reduced memory will prevent the system from posting. Backward compatibility covers 2133, 2400 and 2666 speeds, but the platform must explicitly support registered DIMMs.

Steady-State ECC Throughput

Under sustained load the registered buffer and ECC logic maintain data integrity without the correctable-error spikes seen in unbuffered modules. The CL21 latency at 2933 MT/s delivers consistent bandwidth for multi-threaded server tasks rather than burst-oriented benchmarks. Continuous operation at 1.2V keeps thermal output predictable inside dense GPU server chassis. The module is validated for 24/7 duty cycles in qualified platforms.
