III. INSTALLATION
5. Voltage Regulator Output Selection (VID0, 1, 2)
These jumpers set the voltage supplied to the CPU. Switching regulators allow
some jumper settings to be the same for two voltages of different power planes.
Intel Pentium (P54C)
(75MHz-200MHz)
Pentium MMX (P55C)
(150MHz-233MHz)
AMD-K6
(PR166 and faster)
AMD-K5
(PR75-PR133)
IBM/Cyrix 6x86(MX)
(PR166 and faster)
IBM/Cyrix 6x86(M1)
(PR166 and faster)
WARNING! Because CPU designs change rapidly, the table below is only in-
tended as a simple guideline and thus may not be true for your CPU. Always
refer to the CPU documentation for your CPU’s voltage and then set the appro-
priate VID jumpers according to the illustration below.
