1. Setting Jumpers
1-A. CPU Speed Settings (Switch S4)
There are two steps to set the CPU speed. First, set the clock multiplier with
jumpers JP11-JP14 according to the specification of your CPU using the chart
below. There is no need to set the bus speed. The motherboard auto-detects
the bus speed of the CPU. Presently all Celeron CPUs use a 66MHz bus
speed. Tyan does not recommend operating CPUs, memory, or PCI Bus at
higher than rated speed. Tyan takes no responsibility for any problems
related to overclocking any bus or component on the system board.
