Manufacturer description

The Crucial CT51264BF160B is a single 4GB DDR3/DDR3L SODIMM. It fits laptops, notebooks and other systems that take standard 204-pin DDR3 SODIMM memory. It runs at up to 1600 MT/s (PC3-12800) with CL11 latency, so it is a direct match for machines rated for DDR3-1600 memory. The module is dual-voltage and runs at either 1.35V (DDR3L) or 1.5V (standard DDR3). One part covers both, so you don't need to track down separate low-voltage and standard-voltage sticks. It is unbuffered and non-ECC, which is what consumer notebooks expect. It also uses 4Gb-density chips, a newer technology than…

SpecPicks Verdict

SpecPicks scored Crucial 4GB Single DDR3/DDR3L 1600 MT/S (PC3-12800) Unbuffered… using a rating × review-volume × price-fit model applied to published specs and reviews across the memory & ram category. Micron's memory & ram lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for memory & ram of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will this work in a laptop that requires DDR3L low-voltage memory?

Yes. The CT51264BF160B is dual-voltage and can run at 1.35V, the DDR3L standard. It can also run at 1.5V, so the same module covers both DDR3L and standard DDR3 systems.

Can I use it in an older laptop that takes standard 1.5V DDR3?

Yes. The module also runs at 1.5V and uses the industry-standard 204-pin DDR3 SODIMM layout, so it fits computers that take DDR3 SODIMM memory. Check your system's maximum supported capacity per slot first.

Will this memory fit a desktop PC?

No. This is a 204-pin SODIMM, the smaller module used in notebooks and compact systems. Desktops that use full-size DIMM slots need a different module.

Is this module ECC or registered memory?

Neither. It is unbuffered, non-ECC memory, the type used by consumer laptops and notebooks. Systems that require ECC or registered memory need a different part.

What warranty does the Crucial CT51264BF160B include?

Warranty terms are not listed in the product details here. Check the product listing or Crucial's support site for current warranty coverage.
