4 GB DDR3L 1600 SO-DIMM

This 4 GB Avarum module is a 204-pin DDR3L SO-DIMM rated at 1600 MT/s (PC3L 12800) with CL11 timing and 1.35 V operation. It is built for notebooks and small-form-factor systems that require low-voltage DDR3 memory. Unbuffered and non-ECC, it installs directly into a compatible slot.

Upgraders with DDR3L slots

The module suits owners of laptops that specify DDR3L 1600 memory and have a free SO-DIMM socket. It will not work in systems that only accept DDR3 at 1.5 V, nor in machines built for a different DDR generation. Buyers needing ECC or registered DIMMs should look elsewhere.

1.35 V DDR3L voltage

The 1.35 V rating is the single specification that decides fitment: the host platform must support DDR3L low-voltage operation. If the service manual or BIOS lists only 1.5 V DDR3, this module is not compatible.

Questions about this item

Does the CT51264BF160B come as a single stick or do I need to buy a pair?

The module is sold as one 4 GB SO-DIMM; add a second stick only if your laptop has two slots and you want 8 GB total.

When should I choose this 4 GB DDR3L 1600 stick instead of an 8 GB or 1600 MHz DDR3 version?

Pick this 1.35 V CL11 module when your laptop specifically requires DDR3L rather than standard 1.5 V DDR3 and you only need a 4 GB upgrade.

What does the PC3L 12800 rating mean once the RAM is installed?

It confirms the stick runs at 1600 MT/s with 11-11-11 timings at 1.35 V, matching the JEDEC DDR3L 1600 standard for low-voltage notebooks.
