Computer-Memory


Memory holds key program code and information in the binary format (0 or 1) that is used and processed by the CPU. Read more on how the computer memory
module works here. Each day, larger and more powerful processors are devised and these need more storage/faster memory to take advantage of all that extra processing power. These demands have resulted in a whole range and variety of memory types and products for the computers and other devices. Types including RAM, Dynamic RAM, Static Ram, Flash memory, L1 and L2 Cache etc…



Consider the following, before making a selection or RAM for your computer:

  • Motherboards can support different types of RAM (DDR, DDR2, SDRAM…) Make sure you refer to the user manual and take note of the type of RAM that your motherboard supports.
  • Make sure your RAM bus speed (100 or 133 MHz) matches that of the motherboard. If you install two RAMs of differing speeds on your motherboard, they will run at a slower speed.
  • Amount of RAM needed. Could be 1, 2 or 4 GB depending on the utility of your machine and what it’s used to run. Assuming, your motherboard has 2 slots for 2 DDR RAMS and you want to install 1GB worth RAM on your machine. Make sure you buy 2 RAMS of 512MB storage each instead of just ONE 1GB RAM. This way, even if one of the RAM blows out, you’ll atleast have the other one working!
  • Check the number of Pins and the Pin size of the RAM. This must match with your motherboard’s memory slot.

How much computer memory do I need?

Well, the general rule is – “more memory, better performance” but, remember there’s also a limitation to the amount of memory supported by your motherboard! Cost of memory chips being pretty low, you can scale up to the maximum amount that is supported by your board. If you are on a very strict budget, 512 MB of RAM should be able to support most of your applications.

How do I troubleshoot memory problems?

  1. Use memory testing hardware. Like the one from CST. These are by far the most effective way to test your RAM functionality.
  2. Use computer memory module testing software. Although this is not as effective as hardware testing, the prices are low. Check out memtest86 or pc-diagnostics

Contact Corrosion:

Over time, dust may collect at the contacts of RAM with sockets. Also make sure that both the contact surface of your RAM and motherboard socket are of the same material (Tin or Gold). Use a cotton swab and just gently wipe off any dust on the surface.
