A small outline dual inline memory module (SODIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected.
200-pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)
The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.
The fast, easy way to improve your laptop's performance
There's an easy cure for a slow computer: more memory. Designed to help your system run faster and smoother, Crucial laptop memory is the amazingly easy and affordable way to improve your system's performance. Load programs faster. Increase responsiveness. Run data-intensive applications with ease, and increase your laptop's multitasking capabilities.
Make everything on your computer faster
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 fast by increasing the speed of your memory and installing more of it.
Multitask with ease
You can 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 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 when using the advanced memory technology. 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.
