In short, 204-pin small outline dual inline memory modules (SODIMMs) are the form factor used to provide DDR3 memory modules for notebook computers and other small form factor computing platforms. 204-pin SODIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds.
To use DDR3 memory, your system must have both a 204-pin SODIMM slot and a chipset that supports DDR3 memory. A DDR3 SODIMM will not fit into DDR2 or DDR memory sockets.
SODIMMs are smaller and thinner than regular DIMMs, and the 204-pin SODIMM PCBs are always ~2.6 inches long and are usually around 1.18 inches high (though the heights can vary slightly). They consist of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The number of memory components on a 204-pin SODIMM's printed circuit board (PCB) can vary, but the PCB will always have 102 pins on the front and the back both, for a total of 204 pins. The gold pins on the bottom of the SODIMM provide the connection between the memory module and the memory socket.
Memory is a component in your computer that allows for short-term data access. Since your system's moment-to-moment operations rely on short-term data access - loading applications, browsing the Web or editing a spreadsheet - the speed and amount of memory in your system plays a critical role. Load apps in seconds by increasing the speed of your memory and installing more of it.
Multitask with ease
If you're like us, you use your computer to do lots of things at once. You might be editing a document, while also looking at pictures and browsing the Internet. This naturally leads to a performance problem: every app you're running requires memory and competes for a limited pool of resources. Overcome this by installing high-density modules in each memory slot for seamless multitasking.
Extend battery life
One of the most important aspects of laptop performance is battery life. By upgrading your memory, you can potentially take advantage of lower voltage modules - and increase energy efficiency by up to 40% when using the latest memory technology. 1 What's more, by simply installing more memory, you'll reduce the number of times your system has to access the hard drive (paging). Less paging means tasks are done faster - using less battery power.
Maximize the value of your system
At a fraction of the cost of a new system, a memory upgrade is one of the most affordable ways to increase performance. Get more out of your laptop by giving it the resources it needs to perform.
