Pros & Cons

Pros

  • ✓ Dual voltage 1.35V/1.5V works in both DDR3L and older 1.5V DDR3 boards
  • ✓ 8GB total across 2x4GB modules fills two slots and enables dual-channel
  • ✓ Standard 240-pin non-ECC UDIMM layout fits mainstream desktop boards
  • ✓ Crucial System Scanner and Advisor Tool confirm fit before you buy

Cons

  • ✗ CL11 latency is loose next to tighter DDR3 kits at the same 1600 MT/s
  • ✗ 1600 MT/s is the ceiling; no headroom above PC3-12800 rated speed
  • ✗ Non-ECC only, so it is unsuitable for ECC workstations and servers
  • ✗ 2Rx8 dual-rank can limit slot population on some older chipsets

Manufacturer description

The Crucial CT2K51264BD160B is an 8GB DDR3L kit built from two 4GB UDIMM modules, aimed at owners of older desktops who want more headroom without replacing the machine. Each module runs at up to 1600 MT/s with CL11 latency on the standard 240-pin unbuffered, non-ECC layout, so it drops into any desktop board that accepts DDR3L UDIMMs. The dual-voltage design is the practical differentiator: the kit operates at either 1.35V or 1.5V, which lets it work in low-voltage-only boards as well as older 1.5V DDR3 platforms. The 2Rx8 dual-rank configuration and PC3-12800 rating cover the common sweet…

SpecPicks Verdict

SpecPicks scored Crucial RAM 8GB Kit DDR3 1600 MHz CL11 Desktop Memory CT2K51264BD160B 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. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this Crucial kit work in a motherboard that only supports 1.5V DDR3?

Yes. The CT2K51264BD160B is dual voltage and operates at either 1.35V or 1.5V, so it runs in both DDR3L and standard 1.5V DDR3 desktop boards.

How much memory do I actually get, and how many slots does it use?

You get 8GB total as two 4GB modules, so it occupies two DIMM slots and can run in dual-channel mode on boards that support it.

What speed and latency does this kit run at?

Up to 1600 MT/s with CL11 latency, rated PC3-12800. The configuration is 2Rx8 dual-rank, unbuffered and non-ECC.

Will this fit my laptop?

No. This is a 240-pin UDIMM in the desktop form factor. Laptops use SODIMM modules, so you would need a different Crucial part.

How do I confirm this memory is compatible with my computer?

Run the Crucial System Scanner or use the Crucial Advisor Tool, both of which report compatible modules for your specific system before you order.
