Intel GA-G1975X Robust Graphics Booster, A.2, CPU Host Clock Control, CPU Host FrequencyMhz

Robust Graphics Booster

Select the options can enhance the VGA graphics card bandwidth to get higher performance.

Auto	Set Robust Graphics Booster to Auto. (Default value)
Fast	Set Robust Graphics Booster to Fast.
Turbo	Set Robust Graphics Booster to Turbo.

C.I.A.2

C.I.A.2 (CPU Intelligent Accelerator 2) is designed to detect CPU loading during software program executing, and automatically adjust CPU computing power to maximize system performance.

Disabled	Disable this function. (Default value)
Cruise	Set C.I.A.2 to Cruise. Automatically increase CPU frequency(5%,7%) by CPU
	loading.
Sports	Set C.I.A.2 to Sports. Automatically increase CPU frequency(7%,9%) by CPU
	loading.
Racing	Set C.I.A.2 to Racing. Automatically increase CPU frequency(9%,11%) by CPU
	loading.
Turbo	Set C.I.A.2 to Turbo. Automatically increase CPU frequency(15,17%) by CPU
	loading.
Full Thrust	Set C.I.A.2 to Full Thrust. Automatically increase CPU frequency(17%,19%) by
	CPU loading.

Warning: Stability is highly dependent on system components.

CPU Host Clock Control

Disabled	Disable CPU Host Clock Control. (Default value)
Enabled	Enable CPU Host Clock Control.

CPU Host Frequency(Mhz)

100Mhz ~ 600Mhz Set CPU Host Clock from 100Mhz to 600Mhz. The actual range depends on the CPU you install.

If you use an 800Mhz FSB processor, please set CPU Host Frequency to 200Mhz. If you use a 1066Mhz FSB processor, please set CPU Host Frequency to 266Mhz.

PCI Express Frequency(Mhz)

Auto	Set PCI Express frequency automatically. (Default value)
90Mhz ~ 150Mhz	Set PCI Express frequency from 90Mhz to 150Mhz.
PCI Frequency(Mhz)
Auto	Set PCI frequency automatically. (Default value)
33.3Mhz ~ 37.5Mhz	Set PCI frequency from 33.3Mhz to 37.5Mhz.

System Memory Multiplier

Wrong frequency may make system can't boot, clear CMOS to overcome wrong frequency issue. for FSB(Front Side Bus) frequency=1066MHz,

1.50	Memory Frequency = Host clock X 1.50.
2.00	Memory Frequency = Host clock X 2.00.
2.50	Memory Frequency = Host clock X 2.50.
2.0+	Memory Frequency = Host clock X 2.0+.
2.66	Memory Frequency = Host clock X 2.66.
3.33	Memory Frequency = Host clock X 3.33.
3.00	Memory Frequency = Host clock X 3.00.
4.00	Memory Frequency = Host clock X 4.00.
Auto	Set Memory frequency by DRAM SPD data. (Default value)
