3-8 Chapter 3
¤
When the CPU is single voltage, the following options will be
displayed to set up the voltage:
/
Plane voltage:
ä
3.52v : For Intel VRE standard CPUs and AMK-K5 or Cyrix
8x86 CPUs
ä
3.38v : For Intel STD and VR standards CPUs
¤
When the CPU is dual voltage , two options will be displayed to
set up Vcore and Vio plane voltage
/
Core Plane Voltage:
ä
2.90v : For AMD K6-200 CPU.
ä
2.80v : For Intel Pentium MMX and Cyrix 6x86L CPU.
ä
2.70v : For future CPUs.
ä
2.50v : For future CPUs. (If hardware supports.)
ä
3.20v : For AMD K6-233 and future CPUs. (If hardware
supports.)
/
I/O Plane Voltage:
ä
3.52v : Reserved
ä
3.38v : Some CPUs from AMD need this I/O Plane Voltage.
ä
3.30v : For most of the dual voltage CPUs (default)
currently available.
The CPU voltage must be set according to voltage indications via
CPU Marking given by the manufacturer. Since the CPU voltage will
decrease as technology improves, we have reserved some options
according to what we can forecast from present documentation. We
cannot give you detailed information about the voltage required by each
kind of CPU in this chapter. For the correct values, refer to appendices B,
C and D.

Set up the voltage via CPU Marking:
If you consider using the Appendices to set up as too complicated,
you can use the CPU Marking: within the options under
“

set up via CPU Marking on the CPU.
