Speed DDR3L 1600 (PC3L 12800)

  • ECC protection guards data integrity in server workloads
  • 16 GB quad-channel kit (4 × 4 GB) scales memory capacity
  • DDR3L 1600 MHz at 1.35 V reduces power draw
  • Unbuffered 240-pin DIMM fits compatible server boards
  • Single-rank 1Rx8 organisation supports dense memory configurations

Server & workstation memory kit

This 16 GB kit contains four 4 GB DDR3L 1600 ECC UDIMM modules built for servers and workstations only. It is not compatible with desktop or laptop computers. The quad-channel configuration helps speed up loading times and improves responsiveness under heavier workloads. Each module is tested for dependable operation in supported systems.

Low-voltage DDR3L 240-pin DIMMs

Modules run at 1.35 V and can also operate at 1.5 V for broader platform compatibility. The 240-pin DIMM form factor fits DDR3/DDR3L server slots that accept ECC unbuffered memory. Single-rank 1Rx8 organisation with CL11 latency supports stable data integrity in multi-channel layouts. Major-brand chips are used throughout the kit.

Upgrade for DDR3 ECC UDIMM platforms

Replaces smaller-capacity DDR3 ECC unbuffered kits or fills empty slots in compatible servers and workstations. The jump is worth it when your workload needs more than the current memory ceiling allows and the system supports quad-channel DDR3L 1600 operation. Verify your platform’s qualified-vendor list before installing.

Questions about this item

What speed and bandwidth does the PC3L-12800 DDR3L interface deliver in practice?

The kit runs at 1600 MHz with a peak transfer rate of 12800 MB/s per module, operating at 1.35 V for DDR3L low-voltage compatibility.

What physical slot and pin count does this 240-pin DIMM kit require?

Each 4 GB module uses a standard 240-pin DDR3 DIMM slot; the quad-channel kit occupies four such slots on a server or workstation motherboard.

How are the four modules installed for quad-channel operation, and what step is often missed?

Populate all four slots following the motherboard’s channel guide, ensure each DIMM clicks fully into its latch, and verify the BIOS detects 16 GB at 1600 MHz.
