|How do I add more RAM to my
The first place to start is to look in the manual that came with your computer. RAM comes in several different varietys, 30 pin and 72 pin. Older computers, like the 486 and 386 probably use 30 pin SIMMs (Single Inline Memory Modules). The new computers, like Pentiums and even some 486s, use 72 pin SIMMs.
You'll need to look in the manual for the computer to see if it needs PARITY or Non-PARITY SIMMs. The manual will also let you know what speed of RAM that the computer's motherboard will accepts. Typical speed or RAM are 70ns (nanosecond) or faster.
Pentium computers typically require you to insert RAM in pairs. However, older 486 computers allow you to place single SIMMs.
