Speed DDR3L 1600 (PC3L 12800)

  • 16 GB dual-channel kit expands server memory capacity
  • DDR3L 1600 MHz speed accelerates data throughput
  • ECC unbuffered design detects and corrects memory errors
  • Low 1.35 V operation reduces power draw and heat
  • 240-pin DIMM form factor fits compatible DDR3 server slots

Server DDR3L ECC Kit

This A-Tech kit provides 16GB of DDR3L 1600 ECC UDIMM memory across two 8GB modules. It is built for servers and workstations that require error-correcting unbuffered DIMMs. The dual-rank 2Rx8 organisation suits platforms that populate two channels for bandwidth. Desktop and laptop systems cannot use these modules.

DDR3L Voltage And Speed Limits

The modules run at 1.35V and are rated for PC3L-12800 at 1600 MHz with CL11 latency. They can also operate at 1.5V where the platform demands standard DDR3 voltage. Systems limited to lower speeds will downclock the kit automatically. Boards that only accept registered or fully buffered DIMMs will not post with this unbuffered design.

Straightforward DIMM Installation

Each 240-pin DIMM keys into the slot in one orientation; press until the ejector tabs click. Populate matching channel slots as the system manual directs to enable dual-channel mode. The most common issue is mixing these unbuffered ECC sticks with registered modules, which prevents boot. Another frequent cause of failure is installing the kit in a desktop board that lacks ECC support.

Questions about this item

Should I choose the 16GB dual-channel kit or buy single 8GB modules?

The 16GB kit contains two matched 8GB modules tested together for dual-channel operation, which is the simplest way to reach 16GB on a compatible server or workstation.

What does the 1600 MHz speed deliver in a real server?

At 1600 MHz with CL11 timing, the modules provide 12800 MB/s peak bandwidth per stick, giving your system faster data throughput for multi-threaded workloads.

How does the DDR3L 1.35V standard affect compatibility and power?

These DDR3L modules run at 1.35V but can also operate at 1.5V, so they fit DDR3L and standard DDR3 slots while reducing power draw in low-voltage platforms.
