There is no single computer that can run without random access memory that is the RAM. Computer would not even turn on without a RAM, this is because when a computer turns on the operating system is loaded into the sdram ddr memory. This means that the booting process will be aborted immediately if the RAM is noted to be unavailable. You therefore need to know what type of sdram ddr memory your computer uses, it can be an SDRAM (synchronous DRAM) or DDR (Double data rate SDRAM). The hard thing about these RAM is determining what type of sdram ddr memory your computer uses. Below are some ways in which you can determine if your RAM is SDRAM or DDR memory.
You first need to know that sdram ddr memory is usually expanded to the power of 2, a good example is 16, 32, 64, 128, 256, and 512 and so on. These are the size that sdram ddr memory is provided in. It is important to know this because you will be able to know what size of sdram ddr memory you will need in your computer.
The most effective way of determining whether RAM you are using is SDRAM or DDR memory is opening your computer case and checking the number of sockets that are provided for the RAM. Your computer will have one of the three types of sockets. One type is the SIMM (single in-line memory module) which is 30-pin and 3 inches long, there is also the SIMM 72-pin is usually 4 inches long and the DIMM (dual inline memory module) 1698 pin is about 5 inches long. The DIMM uses an SDRAM memory while the other two SIMM use the DDR memory.
To determine the type of sdram ddr memory you have to learn how your computer reads different sdram ddr memory sizes. For example when you are using a Pentium processor, 32 MB of sdram ddr memory this uses 8 modules of 4 MBs. Upgrading this to 64 MB will require adding 8 more modules of 4 MB RAM.
You can also determine whether your RAM is SDRAM or DDR memory by checking through the operating system as this may not provide you with the accurate information you need. You will find this information in the control panel on your computer but and depending on the processor you are using it will be easy to tell whiach memory your computer uses.
You can also look for speed parity to determine the type of sdram ddr memory you have. The SDRAM and DDR are the most common type. If your computer has Pentium and Celerons then you have an SDRAM memory. And if you are using the latest type of processors like Pentium 4 then you are using DDR.
RAM is an important tool tha every computer needs in order to execute all its applications. Without it no computer would function at all. If you need to know what ram your computer uses, the above simple steps will enable you differentiate between Sdram and Ddr memory.
