32GB DDR3L ECC Registered kit for Supermicro

This 32GB kit contains two 16GB DDR3L 1600 CL11 registered DIMMs built for Supermicro SuperBlade 7127R, 7127RG, 7127RG3, 7142G and 7427R systems. It is designed for servers and workstations that require ECC error correction and registered buffering. Standard desktop computers cannot use this memory.

Verify 240-pin DDR3L slots

Before ordering, confirm the blade chassis has 240-pin DDR3L DIMM slots and that the system BIOS accepts registered ECC modules. This memory will not work in unbuffered consumer platforms and cannot be mixed with non-ECC or unbuffered DIMMs. Check the Supermicro qualified vendor list for exact population rules.

Low-voltage DDR3L runs at 1.35V without a heat

Operating at 1.35V, these modules draw less power than standard DDR3 and generate modest heat under typical server loads. No heat spreader is fitted, so airflow through the blade enclosure handles cooling. Acoustic impact is negligible because the memory itself has no moving parts.

Questions about this item

What comes in the box and is anything else needed to install it?

The kit contains two 16 GB DDR3L 1600 CL11 2Rx4 240-pin 1.35 V ECC Registered RDIMM modules. No extra parts are required for installation in a compatible Supermicro SuperBlade server.

Which capacity version should I choose for my SuperBlade 7127R or 7427R?

This 32 GB kit (2 × 16 GB) is the only capacity offered under part number 1R6T32R4032P; select it when you need a matched pair of 16 GB registered ECC modules for those SuperBlade models.

What does the PC3L-12800 rating mean once the memory is running in my server?

PC3L-12800 indicates a peak transfer rate of 12 800 MB/s at 1 600 MHz with CL11 latency at 1.35 V, delivering registered ECC bandwidth for the supported SuperBlade 7127R, 7127RG, 7127RG3, 7142G and 7427R series.
