OWC 128GB DDR4 3200 PC4-25600 CL22 4Rx4 288-pin ECC LRDIMM memory upgrade

OWC 128GB DDR4 ECC LRDIMM for Gigabyte Servers

This 128GB DDR4 3200 ECC Load Reduced DIMM is built for Gigabyte G242-P34, G242-P35, G242-P36, G242-Z10 and G242-Z11 servers and workstations. It operates at PC4-25600 with CL22 latency and a 4Rx4 rank configuration. The module runs at 1.2V and uses a 288-pin form factor without a heat spreader. It is not compatible with standard desktop computers or with unbuffered and registered ECC memory types.

Thermals Noise and Power at 1.2V

The module operates at the standard DDR4 voltage of 1.2V, which helps limit power draw during typical server workloads. Without a heat spreader, thermal performance relies on system airflow across the bare PCB. JEDEC compliance ensures the DIMM meets standard electrical and thermal specifications for sustained operation in qualified platforms. Acoustic output is determined by the server chassis fans rather than the memory itself.

Sustained Load Behaviour and Compatibility

ECC Load Reduced technology reduces electrical load on the memory bus, allowing stable operation at full 128GB capacity during extended compute tasks. The DIMM is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds for flexible deployment. It matches Micron MTA72ASS16G72LZ3G2, Samsung M386AAG40AM3-CWE and Hynix HMABAGL7ABR4N-XNT5 part numbers for direct replacement. Mixing with other memory types is not supported.
