Kit composition and fit

This 8 GB kit contains two 4 GB SODIMM modules built to the DDR3L 1600 standard with a CAS latency of 11 and 1.35 V operation. It targets owners of compatible Intel-based laptops or small-form-factor desktops that accept 204-pin unbuffered non-ECC memory.

Installation notes

Each stick measures 67.56 mm by 29.97 mm and uses the standard 204-pin SO-DIMM keying, so it slides into the slot without tools. The low-profile design has no heat spreader, which avoids clearance issues in tight chassis, but the modules must be seated firmly until the side clips click or the system will not POST.

Sustained operation

Running at the rated 1600 MT/s with 11-11-11 timings, the kit delivers consistent bandwidth during extended workloads because the 1.35 V supply keeps thermals modest even without a spreader. Systems limited to DDR3L voltage will remain stable, while platforms that only support 1.5 V DDR3 cannot use this memory.

Questions about this item

How can I verify the kit is running at 1600 MT/s with CL11 timing after installation?

Open Task Manager or CPU-Z and confirm the memory frequency shows 800 MHz (DDR3L 1600 effective) with timings of 11-11-11 at 1.35 V.

What comes in the CT2KIT51264BF160B package and do I need extra parts?

The box contains two 4 GB 204-pin DDR3L SODIMM modules; no screws, tools or heat spreaders are included or required.

Should I choose this 8 GB dual-channel kit or a single 8 GB stick for my laptop?

Select this 2 x 4 GB kit to enable dual-channel bandwidth on platforms that support it; a single 8 GB module would run in single-channel mode.
