Appendix I: Over Clocking

Important

Before you attempt to overclock your system, we strongly recommend that you obtain a thorough understanding of all of the variables, procedures, and the potential risks associated with overclocking. Because we cannot control of all of the possible variables that exist (i.e. memory, AGP card, user configurations, cooling 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 of certain components of your system above and beyond what those components were rated for. With this mainboard, depending on the model, you may be able to overclock some or all of the following:

CPU Speed

FSB (Front Side Bus) frequency DDR (Memory) frequency

AGP (Accelerated Graphics Port) frequency PCI (Peripheral Connect Interface) frequency SRC (Serial Reference Clock) frequency

How to calculate your new frequencies.

With this mainboard, the frequencies mentioned above are calculated using individual formulas. These formulas have a single “CPU Host Frequency” in common. For each of the items above there is also a multiplier or a divisor that is applied to the “CPU Host Frequency” to determine the final frequency for each component as shown in the following formulas.

CPU Speed	=	CPU Host Frequency	*	CPU Clock Ratio
FSB frequency	=	CPU Host Frequency	*	FSB multiplier
DDR frequency	=	CPU Host Frequency	*	DDR:CPU Ratio
AGP frequency	=	CPU Host Frequency	/	AGP divisor
PCI frequency	=	CPU Host Frequency	/	PCI divisor
SRC frequency	=	CPU Host Frequency	/	SRC divisor

Configuring your 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 multiplier for Intel based mainboards will always be fixed at 4. The AGP, PCI and SRC frequencies are all determined by the BIOS setting AGP/ PCI/ SRC Speed Setting.
