RAM comes in many different kinds of configurations and types-and runs at many different speeds, as well. Before you upgrade, you need to know how to spot the different types. Pictured in these steps are the different types of RAM, including the older-style DIPs and newer SIMMs and DIMMs. Step 1: Dual Inline Packages (DIPs) If you have an older computer, it might use an older kind of memory called a dual inline package (DIP). DIPs plug directly into their own sockets on the motherboard. It''s difficult to find DIPs today because they''re old. They come in pairs or sets of eight. Step 2: Single Inline Memory Modules SIMMs (Single Inline Memory Modules) plug into long, matching sockets on your motherboard. SIMMs have more capacity than DIPs. Typically, a motherboard has several banks of SIMM sockets into which you plug SIMMs. SIMMs come in 30-pin and 72-pin formats. 30-pin SIMMs usually have less capacity than 72-pin, and often come with capacities of 256K, 1MB, 2MB, and 4MB. 72-pin SIMMs come in 1MB, 2MB, 4MB, 8MB, 16MB, and 32MB. Step 3: Dual Inline Memory Modules

With the addition of more RAM, you''ll be able to keep more programs open at once, speed up program launches, and experience fewer system crashes. Plus, it''s a pretty easy upgrade to make, requiring little technical expertise. Click here to find the 100% Compatible RAM for your machine. Why is it important to purchase memory designed and tested for a specific system rather than to use generic memory? While it''s in your best interest to shop around, don''t skimp on quality. Get grade-A memory only. It''s amazing how many program crashes can be attributed to cheap RAM. There are minute timing differences as well as small incompatibilities between systems. This is why all our memory is tested in specific systems to ensure compatibility. We also carry major name brand memory because all memory is not created equal. Some of the well known brands we carry are : Micron, Samsung, Mitsubishi, Hynix, Kingston, Viking and Transcend. what is the difference between RDRAM speed memory?
