1. Setting Jumpers
1-A. CPU Speed Settings (Jumpers JP4, JP5, JP6, JP7)
There are two steps to set the CPU speed. First, set the
clock multiplier
with
jumpers JP4 -7 according to the specification of your CPU using the chart
below. After the system is ready to boot the
BUS Speed
is auto-detected.
Presently all Celeron CPUs use a 66MHz bus speed. (Tyan does not recom-
mend 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.)
