       What is the difference between DDR3, DDR2, DDR, and SDRAM?

       ---------------------------------------------------------
       Most desktops and notebooks use one of four popular types of
       dynamic random access memory (DRAM) for the main system memory.
       Single data rate (SDR) SDRAM is the older type of memory,
       commonly used in computers prior to 2002.
       Double data rate (DDR) SDRAM hit the mainstream computer market
       around 2002 and is a straightforward evolution from SDR SDRAM.
       The most significant difference between DDR and SDR is that DDR
       reads data on both the rising and falling edges of the clock
       signal, enabling a DDR memory module to transfer data twice as
       fast as an SDR memory module.
       Systems implementing the follow-on technology to DDR, called
       DDR2 began to appear in mid-2004. DDR2 achieves speeds beyond
       that of DDR, delivering bandwidth of up to 8.5 GB per second.
       Frequently, DDR2 based systems can use memory installed in pairs
       to run in "dual channel mode" to increase memory throughput even
       further.
       The latest generation of memory technology, DDR3, began to
       appear in systems in late 2007. DDR3 is an evolutionary step
       beyond DDR2 and operates at lower voltages, thereby consuming
       less power, and can transfer data at rates up to 12.8 GB per
       second. Typically, DDR3 based systems can address memory modules
       in banks of 1, 2 or 3. If a system supports it, installing
       memory in matched sets of 2 or 3 modules (dual channel or triple
       channel modes) will deliver greatly increased memory performance
       over running a single memory module by itself.
       Generally speaking, motherboards are built to support only one
       type of memory. You cannot mix and match SDRAM, DDR, DDR2, or
       DDR3 memory on the same motherboard in any system. They will not
       function and will not even fit in the same sockets.
       The right type of memory to use is the one that your computer
       takes! The easiest way to find the right memory for your
       computer is to look up your system in Crucial's Memory Advisor
       tool. The Memory Advisor tool will list only compatible memory
       for your system.
       If you don't know the exact model of your computer, the Crucial
       System Scanner can scan your computer hardware to automatically
       detect your system configuration and give you a report on which
       upgrade is right for you.
