SK hynix HMABAGL7ABR4N-WM 128GB DDR4-2933 ECC Reg server RAM

128GB DDR4-2933 Registered ECC Module

This 128GB DDR4-2933 registered ECC module is built for servers and workstations that require high-capacity, error-correcting memory. It uses a 288-pin DIMM form factor and operates at PC4-23400 speed with a CAS latency of CL22. The dual-rank design helps maximise density per slot. It is intended for systems that support registered DDR4 memory.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. The dual-rank organisation allows the controller to interleave accesses across ranks, sustaining throughput under heavy multi-threaded demand.

Capacity per Module

A single 128GB module delivers very high density, letting you reach large system memory totals with fewer occupied slots. This is the decisive specification for buyers who need maximum capacity per DIMM. Systems that cannot address 128GB per slot or that require unbuffered memory will not be compatible.
