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,
