Speed DDR3L 1600 (PC3L 12800)

  • 16 GB dual-channel kit expands server memory capacity
  • ECC registered DIMM detects and corrects data errors
  • DDR3L 1600 MHz at 1.35 V reduces power draw
  • 2Rx4 dual-rank organisation increases memory density
  • 240-pin DDR3 form factor fits compatible server slots

A-Tech 16GB DDR3L ECC RDIMM Kit

This 16GB kit contains two 8GB DDR3L 1600 registered DIMMs with ECC and a dual-rank x4 organisation. Modules run at 1.35V and fit 240-pin server or workstation slots only.

Suited for DDR3 servers needing registered ECC

Buyers upgrading desktop or laptop systems cannot use these modules because they require registered ECC support. Systems limited to unbuffered non-ECC DDR3 should look elsewhere.

Confirm your platform accepts DDR3L 1600 RDIMMs

Check the motherboard manual for registered ECC qualification and the correct slot population order for dual-channel operation. Verify the maximum supported capacity per DIMM before ordering.

Questions about this item

Does my server motherboard need 240-pin DDR3/DDR3L registered DIMM slots to use this 2Rx4 kit?

Yes, this kit uses 240-pin DDR3/DDR3L registered DIMMs and requires a server or workstation board that supports ECC registered memory; it will not fit or work in desktop or laptop slots.

Can I mix these 1.35V DDR3L modules with existing 1.5V DDR3 registered DIMMs in the same system?

The modules are rated to operate at 1.35V or 1.5V, so they can run alongside 1.5V DDR3 registered DIMMs provided the motherboard supports mixed-voltage operation and both sets run at a common speed and timing.

How do I confirm the kit is running at DDR3L 1600 with ECC active after installation?

Enter the BIOS or UEFI and verify the memory speed shows 1600 MT/s (PC3L-12800), the voltage reads 1.35V or 1.5V, and ECC is reported as enabled for the 16 GB total capacity.
