Crucial RAM 4GB DDR3 1600 MHz CL11 Desktop Memory CT51264BD160B

Bottom line: The Micron Crucial RAM 4GB DDR3 1600 MHz CL11 Desktop Memory CT51264BD160B ($14.24 on Amazon as of 2026-10-06): Dual voltage 1.35V/1.5V drops into both DDR3L and older 1.5V DDR3 boards; main trade-off: 4GB per module is thin for modern multitasking; you will want a pair.

Pros & Cons

Pros

  • ✓ Dual voltage 1.35V/1.5V drops into both DDR3L and older 1.5V DDR3 boards
  • ✓ PC3-12800 speed grade at 1600 MT/s with CL11 latency
  • ✓ Crucial System Scanner and Advisor Tool verify board fit before you buy
  • ✓ Micron component-level and module-level testing behind the module

Cons

  • ✗ 4GB per module is thin for modern multitasking; you will want a pair
  • ✗ 240-pin UDIMM only, so it will not fit laptops or SO-DIMM boards
  • ✗ Non-ECC, so it rules out workstation and server builds needing ECC
  • ✗ 2Rx8 dual-rank config can limit total slots populated on some older boards

Manufacturer description

The Crucial CT51264BD160B is a single 4GB DDR3L UDIMM built by Micron for desktops that take 240-pin, non-ECC memory. It runs at up to 1600 MT/s with CL11 latency, and its dual-voltage design lets it operate at either 1.35V or 1.5V, so it drops into both low-voltage DDR3L boards and older 1.5V DDR3 systems without a BIOS workaround. That flexibility is what makes this module a common pick for reviving Sandy Bridge and Ivy Bridge era builds, budget office towers, and retro PC projects where matched DDR3 sticks are getting harder to source. Specs are unambiguous: PC3-12800 speed grade…

SpecPicks Verdict

SpecPicks scored Micron Crucial RAM 4GB DDR3 1600 MHz CL11 Desktop Memory CT51264BD160B 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 work in my laptop?

No. The CT51264BD160B is a 240-pin UDIMM desktop module. Laptops use SO-DIMM memory, which is a different form factor and will not fit.

Is this DDR3 or DDR3L?

It is a DDR3L module, but it is dual voltage and operates at either 1.35V or 1.5V. That means it works in DDR3L boards and in older 1.5V DDR3 desktop systems.

How do I know it is compatible with my motherboard?

Run the Crucial System Scanner or the Crucial Advisor Tool before ordering. Crucial provides compatibility assurance when you use either tool to confirm the match.

Can I use this in a server that requires ECC memory?

No. This module is non-ECC and unbuffered. Systems that require ECC or registered memory will not accept it.

How fast is it, and what are the timings?

It runs at speeds up to 1600 MT/s with a CL11 latency, carrying the PC3-12800 speed grade. Its rank and configuration is 2Rx8.
