2.1V (Reserved)
JP7 is used to select CPU core
voltage (Vcore), normally it is set
to default 3.45V for INTEL
Pentium P54C. It must be
changed if you have CPU with
different core voltage, such as
INTEL PP/MT MMX (P55C),
AMD K5/K6 and Cyrix 6x86,
refer to the CPU specification for
more details.

K6-233
Warning: The heat dissipation of Intel PP/MT-233Hz, AMD
K6-200/233MHz exceed the original design of this mainboard.
Please make sure that you have installed CPU fan properly if
Intel PP/MT-233 or AMD K6-200/233 is being selected to use.
It may cause your system unstable if you can not meet the
heat dissipation requirement from above CPU type. It is
recommended to adopt larger fan on these CPU for better air
flow in the system.
