Server-grade ECC RDIMM kit

This 32GB kit contains two 16GB DDR3L 1600 registered DIMMs built for Supermicro SuperServer 6027 and 6037 series systems. The modules run at PC3L-12800 CL11 with ECC error correction and registered buffering. They are not compatible with standard desktop boards or unbuffered memory configurations.

Low-voltage DDR3L operation

Each module operates at 1.35V, reducing power draw and heat output compared with standard 1.5V DDR3 in multi-DIMM server deployments. No heat spreader is fitted, so airflow through the chassis manages thermals. The registered design adds one clock cycle of latency but lightens the electrical load on the memory controller.

Two-module upgrade pack

The kit supplies a matched pair of 2Rx4 240-pin RDIMMs so the server can populate channels in balanced pairs. No additional cables, brackets or software utilities are included. Installation is a direct DIMM swap that extends memory capacity for virtualization, database or NAS workloads on the listed SuperServer platforms.

Questions about this item

How do I install these 240-pin DDR3L ECC RDIMM modules in a Supermicro SuperServer 6027B, and what step is often missed?

Power down the server, open the chassis, align the notch on each 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that all 32GB are detected at 1600MHz.

What maintenance or replacement will this 32GB DDR3L 1600 kit need over its service life?

No routine maintenance is required; the modules have no heat spreaders and run at 1.35V, so replacement is only needed if a DIMM fails or you upgrade to a platform that no longer supports DDR3L.

What limit appears first when these CL11 2Rx4 registered DIMMs run sustained workloads in a 6027R series server?

The DDR3L 1600 memory bus bandwidth and CL11 latency become the bottleneck before the registered buffer or ECC logic, capping throughput on memory-intensive tasks.
