Asus P5Q-EM CPU Ratio Setting [Auto], FSB Frequency [XXX], PCIE Frequency [Auto], FSB Strap to North Bridge [Auto], DRAM Frequency [Auto]

CPU Ratio Setting [Auto]

Allows you to adjust the ratio between CPU Core Clock and FSB Frequency. Use the <+> and <-> keys to adjust the value. The values may vary depending on the CPU installed. Configuration options: [Auto] [06.0] [07.0]–[XX.X]

The following two items appear only when you set the Ai Overclock Tuner item to [Manual].

FSB Frequency [XXX]

Displays the frequency sent by the clock generator to the system bus and PCI bus. The value of this item is auto-detected by the BIOS. Use the <+> and <-> keys to adjust the frequency. You can also type the desired frequency using the numeric keypad. The values range from 200 to 800. Refer to the table below for the correct Front Side Bus and CPU External Frequency settings.

FSB/CPU External Frequency Synchronization

Front Side Bus	FSB 1600	FSB 1333	FSB 1066	FSB 800
CPU External Frequency	400 MHz	333 MHz	266 MHz	200 MHz

PCIE Frequency [Auto]

Allows you to set the PCI Express frequency. Use the <+> and <-> keys to adjust the frequency or t���ype ���the �������desired frequency��������� using����� the��� numeric������� keypad�������. ���The ������values range from 100 to 180.

FSB Strap to North Bridge [Auto]

When set to [Auto], the FSB Strap will be adjusted automatically by FSB Frequency and DRAM Frequency.

Congifuration options: [Auto] [200 MHz] [266 MHz] [333 MHz] [400 MHz]

DRAM Frequency [Auto]

Allows you to set the DDR2 operating frequency.

Configuration options: [Auto] [DDR2-667 MHz] [DDR2-800 MHz] [DDR2-1002MHz] [DDR2-1111����MHz]

• Due to chipset behavior, to obtain memory frequency higher than DDR2 800, you can manually adjust DRAM Frequency.

• ���The ���������following �����table �����shows the��� variation��������� of�� DRAM Frequency configuration options according to FSB Frequency settings.

	FSB			DRAM Frequency (MHz)
		Auto	667	800	960	1002	1064	1111	1200
