16GB DDR3L RDIMM for Supermicro Servers

This 16GB DDR3L 1600 registered ECC module is built for Supermicro server platforms that require 240-pin RDIMM memory. It suits administrators upgrading compatible systems to handle larger workloads and virtualisation tasks.

Supermicro Certified with Hynix Components

The module carries Supermicro certification (MEM-DR316L-HL03-ER16) and uses Hynix HMT42GR7AFR4A-PB chips. Registered buffering and ECC protect data integrity, while 1.35V DDR3L operation reduces power draw compared to standard DDR3. The 240-pin form factor fits supported server DIMM slots directly.

Replaces Lower-Capacity or Non-ECC DDR3 Modules

This kit replaces smaller DDR3 RDIMMs or non-ECC memory where registered ECC is required for stability. The jump is worth it when your Supermicro system supports 16GB dual-rank modules at 1600MHz and you need the reliability of certified, low-voltage server memory.

Questions about this item

What does DDR3L 1600 (PC3L 12800) mean for real-world bandwidth?

The module runs at 1600 MT/s with a peak transfer rate of 12800 MB/s. The DDR3L standard operates at 1.35 V, so it draws less power than standard DDR3 while keeping the same 240-pin RDIMM form factor.

Will this 240-pin RDIMM fit my Supermicro server's DIMM slots?

Yes. The stick is a 240-pin registered DIMM (RDIMM) with a 2Rx4 dual-rank layout. It matches the physical keying and electrical load expected by Supermicro platforms that list the MEM-DR316L-HL03-ER16 part number.

What is the correct seating procedure for this registered ECC module?

Power down the server and open the chassis. Align the notch on the module's gold edge with the key in the DDR3 slot, press straight down until both side clips click shut, then verify the module height is flush with neighbouring DIMMs. The step most often missed is confirming the clips have fully latched on both sides.
