14 PCM-5862 User‘s Manual
When the CPU is installed, the lever should snap into place at the
side of the socket.
NOTE: To remove a CPU, pull the lever out to the side a
little and raise it as far as it will go. Lift out the CPU
chip.
When you install a new CPU, be sure to adjust the board settings,
such as CPU type and CPU clock. Improper settings may
damage the CPU.
System clock setting (J1, J2, and J4)
J1, J2 and J4 are used to set the CPU and PCI bus speed to
optimize the system performance. The system chipset will sense
the J1 setting to get the bus frequency, then adjust its internal
timing. J2 is used to set the CPU and PCI clock. J4 is P55C
enable/disable and CPU clock ratio setting jumper. Refer to the
CPU Speed Reference Table (below) for instructions on adjusting
the internal clocks according to the base CPU speed.
