Speed DDR3L 1600 (PC3L 12800)

  • ECC protection prevents data corruption with built-in error correction
  • 64GB total capacity across four 16GB modules for heavy workloads
  • Registered design stabilises signal integrity on DDR3 server platforms
  • 35V DDR3L operation reduces power draw versus standard 1.5V DDR3
  • Quad-channel kit enables maximum memory bandwidth on supported systems

Server DDR3L 64GB Quad-Channel Kit

This 64GB kit contains four 16GB registered ECC DIMMs built for DDR3L 1600 servers and workstations. Each module runs at 1.35V with a CL11 latency and a 2Rx4 organisation. The quad-channel configuration matches platforms that populate four slots per memory controller.

Compatibility limited to registered DDR3 platforms

The modules are designed for servers and workstations that require registered DDR3 or DDR3L memory. Systems that accept only unbuffered UDIMMs, desktop consumer boards, or laptops cannot use this kit. Buyers needing non-ECC or unregistered memory should select a different product.

Registered ECC with 2Rx4 dual-rank layout

The 2Rx4 dual-rank x4 organisation and registered buffer determine whether the motherboard's memory controller can address the full 64GB across four slots. Verify that your platform supports registered ECC RDIMMs and the 2Rx4 rank structure before ordering.

Questions about this item

Will the 1.35V DDR3L modules need any voltage adjustment if the server only supplies 1.5V?

The kit is rated for 1.35V DDR3L operation and can also run at 1.5V, so it works with either voltage without manual adjustment.

At CL11 latency, does the 1600 MHz speed become the bottleneck before the 64GB capacity is fully used?

The modules run at DDR3L 1600 (PC3L-12800) with CL11 timing; under sustained load the memory bandwidth ceiling of 12800 MB/s per channel is reached before capacity limits matter.

Do the registered ECC DIMMs generate noticeably more heat or fan noise when all four slots are populated 24/7?

Each 16GB 2Rx4 RDIMM operates at 1.35V low voltage, keeping thermal output modest; registered buffering adds negligible extra heat compared with unbuffered DIMMs.
