Gigabyte GA-8AENXP-D CPU Host FrequencyMhz, PCI Express FrequencyMhz, Memory Frequency For

CPU Host Frequency(Mhz)

100Mhz ~ 600Mhz Set CPU Host Clock from 100Mhz to 600Mhz.

If you use a 533Mhz FSB processor, please set CPU Host Frequency to 133Mhz. 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)
100Mhz ~ 130Mhz	Set PCI Express frequency from 100Mhz to 130Mhz.

Memory Frequency For

Wrong frequency may make system can't boot, clear CMOS to overcome wrong frequency issue. for FSB(Front Side Bus) frequency=533Mhz,

3	Memory Frequency = Host clock x 3.
4	Memory Frequency = Host clock x 4.
Auto	Set Memory frequency by DRAM SPD data. (Default value)
for FSB(Front Side Bus) frequency=800Mhz,
2.00	Memory Frequency = Host clock x 2.
2.66	Memory Frequency = Host clock x 2.66.
3.00(Note)	Memory Frequency = Host clock x 3.
Auto	Set Memory frequency by DRAM SPD data. (Default value)
for FSB(Front Side Bus) frequency=1066Mhz,
1.5	Memory Frequency = Host clock x 1.5.
2	Memory Frequency = Host clock x 2.
2.66(Note)	Memory Frequency = Host clock x 2.66.
3	Memory Frequency = Host clock x 3.
Auto	Set Memory frequency by DRAM SPD data. (Default value)

Memory Frequency (Mhz)

The values depend on CPU Host Frequency(Mhz) and Memory Frequency For setting.

DIMM OverVoltage Control

Normal	Set DIMM OverVoltage Control to Normal. (Default value)
+0.1V	Set DIMM OverVoltage Control to +0.1V.
+0.2V	Set DIMM OverVoltage Control to +0.2V.
+0.3V	Set DIMM OverVoltage Control to +0.3V.

PCI-E OverVoltage Control

Normal	Set PCI-E OverVoltrage Control to Normal. (Default value)
+0.1V	Set PCI-E OverVoltrage Control to +0.1V.
+0.2V	Set PCI-E OverVoltrage Control to +0.2V.
+0.3V	Set PCI-E OverVoltrage Control to +0.3V.

CPU Voltage Control

Supports adjustable CPU Vcore from 0.8375V to 1.6000V. (Default value: Normal)

Normal CPU Vcore

Display your CPU Vcore voltage.

(Note) To use a DDRII 711 memory module on the motherboard, you must install a 1066MHz FSB processor and set Memory

Frequency For to 2.66.

To use a DDRII 600 memory module on the motherboard, you must install an 800MHz FSB processor and set Memory Frequency For to 3.00.
