Onboard Regulator Output- J100, J101, J103 and JP43
These jumpers set the voltage supplied to the processor. Intel Pentium
processors has only a Single Power Plane and uses the standard 3.3V(STD),
AMD K5 and Cyrix/IBM 6x86 has also have a single power plane and use
3.52V. Currently Intel's new Pentium P55C MMX, AMD K6 and Cyrix/IBM
6x86L with dual power planes, Pentium P55C MMX and Cyrix/IBM 6x86L
requires 2.8V, AMD K6 PR166 and PR200 requires 2.9V; PR233 requires
3.2V.
JP43 is designed to fine tune V
CORE
output from regulator. When the
jumper cap is removed from JP43, it
will increase V
CORE
voltage output
from regulator by 2.5%. Normally,
JP43 is set to close by insert a
jumper cap.
