CPU Clock Ratio

HOT-661/P mainboard provides a Jumper group JP37 to set CPU Speed configure by BIOS or by
hardware jumper.

By inserting jumper pack on AUTO group, the user can Soft-Configure the

CPU Host Clock

and

CPU Clock Ratio

from BIOS.

By removeing jumper pack from AUTO group and inserting mini jumpers on MANUAL group
properly, the user can configure the CPU Clock Ratio (multiplier) manually.

Special Tip for User's Reference Only

HOT-661/P mainboard provides a special

Jumper

JP45

to overspeed your 66 MHz based Pentium II and

Celeron processor to 100 MHz when jumper group
JP37 set to MANUAL.

Normally, CPU Host Clock 100 ~ 112 MHz are not
available for 66 MHz based processor no matter Soft-
Configure or Hard-Configure.

But, when pull out mini jumper from JP45 (let it open),
the user can Hard-Configure your 66 MHz based
processor to 100 MHz.based. For example, overspeed
your 266 MHz (66 MHz x 4) Celeron to 300 MHz
(100 x 3) or more.
