OWC 16GB DDR3L 1600 ECC Registered RDIMM

This 16GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V operation. It uses a 240-pin RDIMM form factor with 2Rx4 organisation and on-board ECC. The part is validated for Supermicro A+ Server 2122TC and 2122TG series platforms. It will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Thermals and power draw

Operating at 1.35V reduces power consumption compared with standard DDR3 modules. The module has no heat spreader, so airflow across the DIMM slots handles cooling. Registered buffering adds negligible latency while improving signal integrity in multi-DIMM configurations. Acoustic impact is zero because the component has no moving parts.

What the bundle changes

The single-module kit lets you add capacity in 16GB increments without forced pair purchases. JEDEC and RoHS compliance ensures the upgrade is warranty-safe for supported Supermicro servers. OWC's in-house testing and advanced replacement programme reduce the risk of compatibility surprises during deployment. Free technical support is included for the life of the product.

Questions about this item

How do I install this 240-pin DDR3L ECC Registered RDIMM in my Supermicro 2122TC server, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retaining clips click shut, then verify in BIOS that the server recognises the full 16GB at 1600MHz CL11; the step often missed is confirming the memory runs at 1.35V instead of defaulting to 1.5V

What maintenance or replacement will this 16GB 2Rx4 module need over its service life?

No routine maintenance is required; keep the server air filters clean so the modules stay cool, and replace only if ECC corrected-error counts rise sharply or a DIMM fails POST — the Limited Lifetime Warranty covers defects

What limit appears first when this DDR3L 1600 CL11 kit runs sustained workloads?

The 16GB capacity ceiling is reached before bandwidth or thermal limits; once the working set exceeds 16GB the system swaps to storage, so add identical 2Rx4 modules in matched channels to scale further
