Server memory kit

This OWC kit provides 128GB of DDR3L ECC registered memory across four 32GB modules. It is built for Supermicro X9DAL, X9DAX, X9DB3, X9DBi and X9DBL motherboards in workstation and server roles. The 1.35V DDR3L 1600 CL11 specification matches the JEDEC standard for these platforms. Buyers needing unbuffered memory or desktop compatibility cannot use this kit.

Replaces lower-capacity RDIMMs

The four 32GB 4Rx4 modules fill four slots to reach the full 128GB capacity supported by the listed boards. It upgrades systems that currently run smaller registered DIMMs or mixed-rank configurations. The jump is worth it when workloads exceed the existing memory ceiling and the board accepts 4Rx4 registered modules at 1.35V. Systems limited to unbuffered memory or lower maximum capacity will not benefit.

Sustained load behaviour

ECC registered operation corrects single-bit errors and reduces electrical load on the memory controller during continuous server workloads. The 1.35V DDR3L voltage lowers power draw compared to standard 1.5V DDR3 during extended runs. CL11 latency at 1600MT/s delivers steady throughput for virtualization, database and file-service tasks. Modules without heat spreaders rely on chassis airflow for thermal stability under load.

Questions about this item

Will these 240-pin DDR3L modules fit the DIMM slots on my Supermicro X9DAX motherboard?

Yes, the 240-pin DDR3L form factor matches the registered DIMM slots on X9DAL, X9DAX, X9DB3, X9DBi and X9DBL series boards.

Do I need to populate all four channels in a specific order when installing the 4Rx4 registered DIMMs?

Install the four 32 GB modules in the same coloured slots per channel; the common mistake is mixing registered and unbuffered DIMMs, which prevents boot.

How do I know when a 32 GB 1.35 V ECC registered module should be replaced?

The ECC logic corrects single-bit errors and logs uncorrectable ones; replace a module when the system log reports repeated corrected or uncorrectable errors on that DIMM.
