Compatible Cyrix CPU Identification
The only Cyrix 6x86-PR166+ CPU that is supported on this
motherboard must be Revision 2.7 or later. Look on the un-
derside of the CPU for the serial number. The number should
read G8DC6620A or later.
8. Voltage Regulator Output Selection (VID0, VID1, VID2, VID3)
These jumpers set the VCORE voltage supplied to the CPU. Switching regulators
allow some jumper settings to be the same for two voltages of different power planes.
AMD-K6-2
(266MHz & faster) AMD-K5
(75MHz-133MHz) IBM/Cyrix 6x86 (M1)
(PR166 & faster) Pentium MMX (P55C)
(150MHz-233MHz) AMD-K6
(166MHz & faster) IBM/Cyrix 6x86 (M1)
(PR166 & faster)
WARNING! Because CPU designs change rapidly, the table below is only intended 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 appropriate VID jumpers according to the CPU Vcore
Voltage Selection illustration.
