Speed DDR3L 1600 (PC3L 12800)

  • 64 GB capacity across eight modules handles heavy server workloads
  • ECC registered design detects and corrects memory errors for data integrity
  • DDR3L 1600 MHz at CL11 delivers fast, responsive performance
  • 35 V low-voltage operation reduces power draw and heat
  • 240-pin 2Rx4 dual-rank layout fits compatible DDR3 server platforms

64GB DDR3L ECC RDIMM kit

This A-Tech kit supplies 64GB of DDR3L 1600 memory across eight 8GB registered DIMMs. It is built for servers and workstations that require ECC error correction and registered buffering. The modules run at 1.35V low voltage while retaining compatibility with 1.5V slots. Dual-rank x4 organisation helps maximise capacity per channel.

Verify DDR3 registered DIMM support

Confirm that your system accepts DDR3 or DDR3L registered ECC RDIMMs in a 240-pin form factor. Desktop and laptop platforms cannot use these modules. Check the motherboard or chassis manual for approved memory configurations, maximum capacity per slot and population rules for dual-rank modules. Ensure the BIOS is current before installation.

Low-voltage operation at 1.35V

Each module operates at 1.35V, reducing power draw and heat compared with standard 1.5V DDR3. Registered buffering adds a clock cycle but lightens the electrical load on the memory controller. In typical server workloads the kit runs within standard thermal limits without requiring exotic cooling. Fan noise remains governed by chassis airflow rather than the memory itself.

Questions about this item

Does the 64GB kit contain eight 8GB modules or do I need to buy extra sticks?

The kit includes eight 8GB modules for a total of 64GB; no additional sticks are required.

Should I choose the 2Rx4 dual-rank version or look for a single-rank alternative?

This kit uses 2Rx4 dual-rank x4 organisation, which is the specified configuration for the listed server platforms.

Will the CL11 1600 MHz rating deliver that speed in my registered DIMM slots?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 latency when installed in compatible registered DIMM slots.
