Compatible Cyrix CPU Identification

The only Cyrix CPU that is supported on this motherboard is labeled Cyrix 6x86 P166+ but must be Revision 2.7 and later. Look on the underside of the CPU for the serial number. The number should read G8DC6620A or larger.

6.Voltage Regulator Output Selection (VID0 - VID6)

These jumpers set the voltage supplied to the CPU. Determine whether your CPU has a Single Power Plane or Dual Power Planes and then the voltage that it uses. Current Intel CPU's marked "Pentium" has only a single power plane and uses the standard 3.38 volts (STD) or 3.5 volts (VRE). Currently Intel’s new Pentium P55C MMX 200MHz is supported at 2.8Volts.
