Server-grade capacity and compatibility

This 128GB DDR4 registered ECC module is built for Supermicro motherboards including the H11SSL-i, H11SSL-NC, H11SSW-iN, H12SSW-iN and H12DSG-O-CPU. It delivers 3200MHz speed at CL22 latency with a 1.2V operating voltage. The 288-pin RDIMM format and 4Rx4 organisation target workstation and server platforms that require registered memory with error correction. Standard desktop systems cannot use this module.

Sustained workload behaviour

Registered buffering and ECC protect data integrity during continuous operation in multi-socket server environments. The module runs at the JEDEC-standard 3200MHz rate without overclocking headroom, so throughput remains stable under long-duration compute tasks. Four-rank density maximises capacity per slot on supported Supermicro boards. Mixing with unbuffered DIMMs is not supported and will prevent boot.

Thermals, noise and power

Operating at 1.2V keeps power draw low for high-density server configurations. No heat spreader is fitted, relying on chassis airflow for cooling in 1U and 2U rackmount designs. Silent passive operation adds no acoustic load to noise-sensitive rack rooms. JEDEC and RoHS compliance ensure consistent electrical and thermal characteristics across the module's service life.

この商品に関する質問

How much power does the 1.2V DDR4 3200 RDIMM draw when the server runs continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, so power draw scales with the 128 GB capacity and 3200 MT/s data rate rather than exceeding the JEDEC baseline.

Which motherboard must I already have for this registered ECC memory to function?

The DIMM is validated for Supermicro H11SSL-i, H11SSL-NC, H11SSW-iN, H12SSW-iN and H12DSG-O-CPU boards that support DDR4 3200 registered ECC.

Can I add this 4Rx4 CL22 stick beside the Supermicro MEM-DR412MC-ER32 modules already in my system?

Yes — it replaces part numbers MEMDR412LHL01ER32, MEMDR412LSL01ER32 and MEM-DR412MC-ER32, so matching rank, speed and voltage allows mixed population.
