A-Tech 128GB DDR4 3200MHz ECC LRDIMM CL22 1.2V Server Memory

128GB DDR4 LRDIMM for Servers

This 128GB DDR4 load-reduced DIMM runs at 3200MHz with CL22 latency and 1.2V operation. It targets server administrators who need high-density ECC memory for virtualisation hosts or database nodes. The single-module design simplifies capacity scaling in qualified platforms.

288-pin registered form factor

The module uses a standard 288-pin DDR4 interface with load-reduced buffering to reduce electrical load on the memory bus. Major-brand chipsets provide the ECC function without a heat spreader, so airflow in the server chassis must be sufficient for passive cooling. The physical layout matches the Samsung M386AAG40MM2-CWE, M386AAG40AM3-CWE and M386AAG40BM3-CWE part numbers listed.

Verify LRDIMM support and rank limits

Confirm that your server platform accepts DDR4 LRDIMM modules and supports 4DRx4 or 4Rx4 rank configurations at this capacity. Check the system documentation for maximum memory per slot and total population rules before ordering. Mixing with other DIMM types or ranks may prevent the system from booting.
