If a computer is slow, it can be fixed quickly: with more memory. Crucial Laptop Memory is designed to run your system faster and smoother, offering one of the easiest and most cost-effective ways to optimize the performance of your system. Programs are loaded faster. The ability to react is increased. Data-intensive applications run smoothly and your laptop's multitasking capabilities are enhanced. Memory is a component of your computer that allows short-term data access. Since the running operation of your system relies on short-term data access (loading applications, browsing the Internet or editing a spreadsheet), the speed and amount of memory in your system play a crucial role. Download applications in seconds by increasing the speed of your memory and installing more memory. You certainly feel the same way: You use your computer to do many things at once. Maybe you're editing a document while you're looking at pictures and surfing the web. This inevitably leads to a performance problem: all the applications you run require storage and compete for a limited pool of resources. Overcome this obstacle by installing high-density modules at each storage location for seamless multitasking. One of the most important aspects of laptop performance is battery life. By upgrading your memory, you may be able to use lower voltage modules - and increase energy efficiency by up to 40% if you use the latest memory technology. In addition, by simply installing additional memory, you reduce the number of times your system needs to access the disk (paging). Less paging means tasks are performed faster - and less battery power is consumed. All you need is a screwdriver, your user manual and a few minutes to install memory - no special computer skills required. Just watch one of our three-minute installation videos and we'll guide you step-by-step through the process. Don't pay a computer store for something you can do yourself in minutes. A memory upgrade costs only a fraction of what a new system costs, making it one of the most cost-effective ways to increase performance. Get more out of your laptop - give it the resources it needs to be powerful.more

General information

Manufacturer Crucial
Product type Memory


Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory.

The main memory (the "RAM") in personal computers is Dynamic RAM (DRAM). It is the RAM in laptop, notebook and workstation computers as well as some of the RAM of home game consoles (PlayStation3, Xbox 360 and Wii).

Hardware application range


A laptop, also called a notebook, is a personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.

In addition to bandwidth and capacity variants, modules can
1. Optionally implement ECC, which is an extra data byte lane used for correcting minor errors and detecting major errors for better reliability. Modules with ECC are identified by an additional ECC in their designation.
2. Be "registered", which improves signal integrity (and hence potentially clock speed and physical slot capacity) by electrically buffering the signals at a cost of an extra clock of increased latency. Those modules are identified by an additional R in their designation, whereas non-registered (a.k.a. "unbuffered") RAM may be identified by an additional U in the designation.
3. Be Fully buffered modules, which are designated by F or FB and do not have the same notch position as other classes. Fully buffered modules cannot be used with motherboards that are made for registered modules, and the different notch position physically prevents their insertion.
