Server-grade DDR3L ECC kit

This 32GB kit contains two 16GB DDR3L 1600 registered DIMMs built for Supermicro X9DR series motherboards. It delivers error-correcting, registered memory for workstations, servers and NAS systems that require 240-pin DDR3L modules at 1.35V.

Sustained load behaviour

ECC registered architecture detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. The 2Rx4 organisation and CL11 latency maintain stable throughput across extended compute or storage tasks without the variability seen in unbuffered alternatives.

Thermals, noise and power

Modules operate at the JEDEC-standard 1.35V without heat spreaders, relying on chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, contributing to lower overall system power draw and silent operation in properly ventilated server enclosures.

Questions about this item

How much power does the 1.35V DDR3L kit draw when the server runs continuously?

At 1.35V the DDR3L modules consume less power than standard 1.5V DDR3, reducing heat output during 24/7 operation.

What motherboard must I already own for this 240-pin registered ECC kit to work?

The kit is validated for Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH and X9DRi series motherboards with DDR3L RDIMM slots.

Can I keep my existing unbuffered DDR3 DIMMs and add these 2Rx4 registered modules?

No, registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered modules.
