ECC Registered DDR3L Kit

This kit provides 16 GB of DDR3L ECC registered memory in two 8 GB modules. It is built for Supermicro X9DRL, X9DRT, X9DRW, X9DRX+ and X9QR7 motherboards in workstation and server roles. The modules run at 1600 MT/s with a CL11 latency at 1.35 V. They are designed to extend the life of existing infrastructure or support new server builds.

Suited for registered ECC slots only

The memory fits servers, workstations, NAS units and routers that accept 240-pin DDR3L registered DIMMs. It will not work in standard desktop boards that require unbuffered non-ECC modules. Mixing with unbuffered memory is not supported. Buyers who need unbuffered consumer memory should look at a different product line.

Steady throughput under load

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded workloads. The 1.35 V operation reduces thermal stress compared with higher-voltage DDR3 modules. Sustained performance depends on the platform memory controller and channel population. Modules without heat spreaders rely on chassis airflow for cooling.

Questions about this item

Which Supermicro motherboard series must I already have for this DDR3L 1600 ECC RDIMM kit to be compatible?

This kit is validated for Supermicro X9DRL, X9DRT, X9DRW, X9DRX+ and X9QR7 series motherboards.

Can I keep my existing unbuffered DDR3L modules and add these registered 1Rx4 DIMMs alongside them?

No. The manufacturer highlights state that registered ECC memory cannot be mixed with unbuffered memory.

After installation, how do I confirm the kit is running at the rated PC3L-12800 CL11 1.35 V settings?

Check the BIOS or a system-information tool such as CPU-Z; it should report DDR3L 1600 MHz, CL11 timings and 1.35 V operation.
