    The two processors must be operating at the same bus speed and the same processor speed, with the switch settings set accordingly for the slower of the two. In fact, only 200 MHz processors are presently supported by HP. The two processors should have the same amount of level-two (L2) cache memory.

    2 System Board Devices on the Processor-Local Bus Main Memory There are eight main memory module sockets, arranged in four banks (A to D). One or two banks are already occupied by the double interline memory modules (DIMMs) that contain the 64 MB or 128 MB of memory that is supplied with the computer (depending on the model).
