Transcript of "Ram"

  1. 1. RAM Computer Maintenance
  2. 2. What is it? • Chip assemblies that store data for very quick recall. The main memory in a computer requires constant power to be able to hold data. Every task performed by a computer requires the program and data to be loaded into memory.
  3. 3. Items to consider when selecting memory for a computer: • Type • Speed • Quantity • Quality • Error detection • Physical module size and pin layout • Single- or double-sided module
  4. 4. TYPES
  5. 5. SDRAM
  6. 6. DDR
  7. 7. DDR 2
  8. 8. DDR 3
  9. 9. Rambus
  10. 10. SoDIMM
  11. 11. MicroDIMM
  12. 12. Finding the Right Memory for a Computer • Check the computer or motherboard manual, the manufacturer’s Web site, or call the manufacturer. • Go to a memory manufacturer’s Web site such as Crucial’s (crucial.com) access the memory upgrade, memory search, or “configurator” program on the homepage and enter the requested information.
  13. 13. Computer Reports the Wrong Amount of Memory • On some computers, the on-board video uses a portion of the memory. • Remember that one kilobyte is 1024 bytes, and that one megabyte is 1024 kilobytes. • Make sure the module is installed correctly. • Some motherboards have restrictions for memory. • You might have a bad memory module.
  14. 14. General Rules for Memory Installation • Use the correct memory for the motherboard. • Follow all instructions from the computer /motherboard and memory manufacturers. • Make sure all the memory modules match. (speed) • Start at the lowest number memory slot, 0 or 1. • Insert the memory in capacity order starting with the highest-capacity module in the lowest number slot. • After you have installed the memory, boot the computer and check the memory.
