Targeted server upgrade

This kit provides 32GB of DDR3L ECC registered memory in a matched pair of 16GB modules. It is built for Supermicro A+ Server 2122TC and 2122TG systems that require registered DIMMs with error correction. The modules will not work in standard desktop boards or alongside unbuffered memory.

Build integration

Each module uses the 240-pin DDR3L form factor and operates at 1.35V, reducing power draw compared to standard DDR3. The registered design places a buffer on the command bus, allowing the memory controller to drive larger capacities per channel. No heat spreader is fitted, so airflow across the slots must be maintained by the server chassis.

Thermals and power

At 1.35V the kit runs cooler than 1.5V DDR3, helping dense server configurations stay within thermal limits. The absence of a spreader means module temperature follows case airflow directly; adequate front-to-rear cooling is expected. Power consumption scales with the 1600MHz data rate and CL11 latency under typical workloads.

Questions about this item

Does the 1600 MHz speed limit throughput first when the server runs 24/7?

The modules run at DDR3L 1600 with CL11 latency, so bandwidth is capped at the rated 12800 MB/s per DIMM under sustained load.

How much extra heat or power do the two 16 GB sticks add during all-day operation?

Each stick operates at 1.35 V without a heat spreader, so thermal output stays low and power draw remains minimal for registered ECC DDR3L.

Which Supermicro A+ Server series must I already have for this 32 GB kit to work?

The kit is validated for Supermicro A+ Server 2122TC and 2122TG series; it requires a platform that accepts 240-pin DDR3L ECC registered DIMMs.
