Increasing the amount of system RAM almost always improves overall system performance. Prior to upgrading or replacing the RAM, answer the following questions:
- What type of RAM does the motherboard currently use?
- Can the RAM be installed one module at a time or must it be grouped into matching banks?
- Are there available RAM slots?
- Does the new RAM chip match the speed, latency, type, and voltage of the existing RAM?
CAUTION: When working with system RAM, work on an antistatic mat and wear a wrist strap. Place the RAM on the mat until you are ready to install it. Store RAM in antistatic packaging.
Remove the existing RAM module by freeing the retaining clips that secure it. Pull it from the socket. Current DIMMs pull straight out and insert straight down. Earlier SIMMs were inserted at an angle to lock into place.
When inserting the new RAM module, make sure that the notches in the RAM and RAM slot on the motherboard align properly. Press down firmly, and lock the RAM into place with the retaining clips.
CAUTION: Make sure to insert the memory module completely into the socket. RAM can cause serious damage to the motherboard if it is incorrectly aligned and shorts the main system bus.
The system discovers the newly installed RAM if it is compatible and installed correctly. If the BIOS does not indicate the presence of the correct amount of RAM, make sure that the RAM is compatible with the motherboard and is correctly installed.
