Note: Please set the CPU host frequency in accordance with your
processor’s specifications. We don’t recommend you to set the
system bus frequency over the CPU’s specification because these
specific bus frequencies are not the standard specifications for
CPU, chipset and most of the peripherals. Whether your system can
run under these specific bus frequencies properly will depend on
your hardware configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
Note: JP23 is only available when the motherboard use 82810E
chipset.
