Replacing Secondary Cache Memory
The CPU module comes with standard or burst secondary cache memory in the form of a single in-line cache
module. Secondary cache memory is designed to greatly improve the performance of the installed CPU(s).
Note that “standard” cache refers to asynchronous cache and “burst” cache to synchronous (higher
performance) cache.
To replace secondary cache memory:
1) Remove the CPU module.
2) Place the CPU module on an anti-static surface.
3) Locate the secondary cache memory socket on the CPU module and remove the currently installed cache
memory module.
CAUTION
Static electricity can cause damage to components. Before handling any cache module,
make sure to discharge all static electricity from the body by touching an exposed metal
surface of the computer’s chassis.
4) Remove the new cache memory module from its anti-static packaging, handling it only by the edges.
5) Install the cache memory module into the socket (Figure 3 - 16). Make sure it is firmly seated into the
socket.
6) Install and secure the CPU module to the main logic board.
