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.
