The switch 1 (SW1) is designated for adjusting the CPU internal frequency ratio. The frequency
ratio is defined in the table below. The internal frequency can be calculated by the following
formula:
CPU internal frequency = frequency ratio x FSB frequency *
* System bus frequency is set in “CPU Host/PCI Clock” of “Frequency / Voltage Control ” in
BIOS SETUP MENU (Please refer to page 49 ).
NOTE: Because Intel
®
has locked the frequency ratio for new CPUs, setting SW1 to
adjust the frequency ratio is useless. However, it is effective for older version
CPUs.
