OWC DDR3L 32GB ECC RDIMM kit

This OWC memory kit provides 32GB of DDR3L ECC Registered RDIMM capacity in a matched pair of 16GB modules. It is built for workstations, servers and NAS systems that require registered memory with error correction. The modules are validated for specific Supermicro X9 series motherboards and will not function in standard desktop computers that use unbuffered DIMMs.

1.35V low-voltage DDR3L operation

The kit runs at the JEDEC-standard 1.35V, reducing power draw and heat compared to standard 1.5V DDR3. With a CL11 latency at 1600MHz, the modules operate within normal thermal limits for registered server memory. No heat spreaders are fitted, so airflow through the chassis manages module temperature during sustained workloads.

240-pin registered DIMM for X9 boards

Each module uses the 240-pin DDR3L RDIMM form factor and a 2Rx4 organisation, requiring a motherboard that supports registered ECC memory. The kit frees two DIMM slots for the full 32GB capacity and cannot be mixed with unbuffered modules. Buyers needing higher densities or different speeds should verify their platform's qualified vendor list before purchasing.

Questions about this item

How do I install the 240-pin DDR3L RDIMMs in my Supermicro X9DRL board and what step is often missed?

Align the notch on each module with the slot key, press straight down until both retention clips snap shut, then verify in BIOS that all 32GB are detected at 1600MHz.

What maintenance or replacement will this ECC registered kit need over time?

No routine maintenance is required; if a module fails, replace the faulty 16GB stick with an identical DDR3L 1600 CL11 2Rx4 1.35V registered DIMM.

What limit appears first when this memory runs under sustained server workloads?

The 1600MHz CL11 bandwidth ceiling and registered-buffer latency become the bottleneck before the 1.35V thermal envelope is reached.
