frequency of CPU host bus and PCI bus. Options are: Default, 100/33, 101/
33, 108/36, 114/38, 120/40, 123/41, 126/31, 133/33, 134/33, 148/37, 152/

MSI Reminds You...
Changing CPU Clock Ratio could result in the instability of the
system; therefore, it is NOT recommended to change the default
setting for long-term usage.
