Intel GA-N650SLI-DS4L user manual FSB-Memory Clock Mode, FSB-Memory Ratio, CPU Host Frequency Mhz

FSB-Memory Clock Mode

Auto	BIOS will automatically set the FSB-Memory clock mode. (Default)
Linked	Allows you to set FSB speed manually; the memory speed changes propor-
	tionally along with the FSB speed.
Unlinked	Allows you to set FSB speed and memory speed individually.

FSB-Memory Ratio

This item is configurable only if the FSB-Memory Clock Mode option is set to Linked.

Auto	BIOS will automatically set the FSB-Memory ratio. (Default)
1:1	Sets FSB-Memory ratio to 1:1.
5:4	Sets FSB-Memory ratio to 5:4.
3:2	Sets FSB-Memory ratio to 3:2.
Sync Mode	Sets FSB-Memory ratio synchronously.

CPU Host Frequency (Mhz)

Allows you to manually set the CPU host frequency. This item is configurable only if the FSB- Memory Clock Mode option is set to Linked or Unlinked. The adjustable range is from 100 MHz to 650 MHz.

For a 533 MHz FSB CPU, set this item to 133 MHz. For an 800 MHz FSB CPU, set this item to 200 MHz. For a 1066 MHz FSB CPU, set this item to 266 MHz. For a 1333 MHz FSB CPU, set this item to 333 MHz.

Important It is highly recommended that the CPU frequency be set in accordance with the CPU specifications.

Actual CPU Clock (Mhz)

The value depends on the CPU Host Frequency (Mhz) setting.

Memory Frequency (Mhz)

This item is configurable only if the FSB-Memory Clock Mode option is set to Unlinked. The first frequency value is adjustable and the second is the current operating frequency of your memory. The adjustable range is from 400 MHz to 1400 MHz.

Actual Memory Clock (Mhz)

The value depends on the CPU Host Frequency (Mhz) and Memory Frequency (Mhz) settings.

PCIe Bus, Slot 1, MHz

Allows you to manually set the clock frequency for the PCIe x16 bus. The adjustable range is from 100 MHz to 150 MHz. The standard clock frequency is 100 MHz.

CPU Clock Ratio (Note)

Allows you to alter the clock ratio for the installed CPU.

The item is present only if a CPU with unlocked clock ratio is installed.

System Voltage Control

Determines whether to manually set the system voltages. Auto lets BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable. (Default: Manual)

(Note) This item is present only if you install a CPU that supports this feature.
