Appendix I: Over Clocking

Important
B efore you attempt to overclock your system, we strongly recommend that you obtain a thorough
un derstanding of all of the variables, procedures,
B ecause we cannot control of all of the possible variables that exist (i.e. memory, AGP card, user
configurations, c ooling apparatus etc), we cannot assume responsibility from damage to any
components of your system due to overclocking.
What is overclocking?
Overclocking is accelerating the processing speed
beyond what those components were rated for. With this mainboard, depending on the model, you
may be able to overclock so
CPU Speed
FSB (Front Sid e Bus) frequency
DDR (Memory) frequency
AGP (Ac celerated Graphics Port) frequency
PCI (Peripheral Connect Interface) frequency
SRC (Serial Reference Clock) frequency
How to calc ulate your new frequencies.
With this mainboard, the frequencies mentioned above are calcu
These formulas have a single "CPU Host Frequency" in common. F
is also a multiplier or a divisor that is applied to the "CPU Host Fr
frequency for each component as shown in the following formulas
C PU Speed =
FSB frequency =
DDR frequency =
AGP frequency =
PCI frequency =
S RC frequency =
Configuring yo ur system for overclocking is simply understanding the formulas above and going into
the BIOS Setup Utility and changing "DDR:CPU Ratio", "CPU Clock Ratio" and "CPU Host
Frequency".
Note that the FSB mu ltiplier for Intel based mainboards will always be fixed at 4. The AGP, PCI and
SRC freque ncies are all determined by the BIOS setting AGP/ PCI/ SRC Speed Setting.
