2 Installing Accessories in Your Computer Installing Cache Memory Installing Cache Memory Caution Static electricity can damage electronic components. Turn off all equipment. Don't let your clothes touch the accessory. To equalize the static electricity, rest the accessory bag on top of the computer while you are removing the accessory from the bag. Handle the accessory as little as possible and with care. Your computer is probably supplied with at least 256 KB of level-two cache in a module on the system board. If your computer does not have 512 KB of level-two cache memory installed, or no level-two cache memory at all, you can install a 512-KB cache memory module for improved performance. (If your computer currently has no level-two cache memory, you can install a 256-KB module instead of installing a 512-KB module. The process is the same as that described below.) Installing the Cache 1 Remove the computer's cover (refer to "Removing the Cover" on page 22). Memory Module 2 Remove the airflow guide to improve access to the system board (refer to "Removing the Air Flow Guide" on page 24). 3 If there is a 256-KB cache memory module installed, remove it (hold it with both hands-one hand at each end of the module-and lift it clear of the cache memory socket). Align the 512-KB cache memory module with the cache memory socket. Check the alignment of the notch-the module will only fit into the socket one way. 33
