FEATURED REVIEWS
Works as expected - Lenovo G560
Tough to review RAM since it either works or it doesn't. I had used the Crucial site to verify this was compatible with my older Lenovo G560 laptop and it was - this is the maximum supported 8Gb. Simply replaced the existing 2 * 2Gb modules with these and booted right up no issue. Just how a RAM upgrade is supposed to be.
Crucial 16 GB SODIMM DDR3L
Product came quickly. Very easy to install. Excellent customer service.
Take the guesswork out of upgrading your Mac with Crucial memory for Mac systems. Since Apple computers often have very specific memory requirements, including particular component densities, speeds and SPD programming specifications, it's important to use memory that's engineered for your Mac. With more than a decade of experience manufacturing and developing memory for all types of Apple computers, trust Crucial memory to optimize your Mac system's performance.
• Increases Mac system performance
• Compatible with Mac systems
• All DDR3 and DDR3L modules are lead- and halogen-free
• Easy to install
• Every single module extensively tested at the component and module level
• Available in SODIMMs, RDIMMs and ECC UDIMMs

Reliability for Mac systems
When you use your Mac system, you expect intuitive, dependable performance. And if you're a Mac Pro user, you expect mission-critical workstation reliability. Expect the same out of your memory. Every module that leaves Crucial Technology doors has been extensively tested at the component level for voltage and temperature resistances, signal integrity and software compatibility. Even better, modules are lead- and halogen-free.
Speed and energy efficiency for Mac systems
A memory upgrade is the fastest, easiest and most affordable way to get more performance out of your Mac system. Standard DDR3 modules help Mac systems reach speeds up to 1600 MT/s. For newer Mac systems, DDR3L modules are available. These modules deliver speeds starting at 1866 MT/s and use 10% less power for improved energy efficiency.
Support for Mac systems
Unsure how to install memory or have an important question about your Mac system Let Crucial Technology team of experts help! Their team knows Apple systems and requirements inside and out and they will provide the technical support you need - no matter which Mac system you're using. From phone support, videos, FAQ articles and do-it-yourself install guides for more than 70 different Mac systems, they have got the resources you need to keep your system up to speed.
Micron quality - a higher level of reliability
As a brand of Micron, one of the largest memory manufacturers in the world, Crucial memory for Mac systems is backed by the same quality and innovation that has produced some of the world's most advanced memory and storage technologies. With a product portfolio that includes upgrades for more than 100,000 systems, they have got one specifically designed for your Mac system.
Memory spec terms
If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.
NON-ECC/Non-parity
Most desktop and laptop computers take NON-ECC or Non-parity memory.
ECC/Parity
ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.
Unbuffered
Most PCs and workstations use unbuffered memory which is faster than registered memory.
Registered/Buffered
Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.
Fully buffered
Designed for next-generation servers, features an advanced memory buffer.
CL -
CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.
Component configuration
(For example: 64Meg x 64) Indicates the size of the memory chip components on the module.
Voltage
For example 2.6V. Indicates the power used by the module. The lower the better.
Note:
As per Apple manufacturer specifications, memory can't be upgraded on (a) many Mac systems made after mid-2012 and (b) retina-based models. Before upgrading your memory, consult your owner's manual to verify that an upgrade is possible.
