Gigabyte GA-946-DS3 User Manual page 48

PCI Express Frequency (Mhz)
Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to
150 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto)
C.I.A.2
CPU Intelligent Accelerator 2 (C.I.A.2) is designed to automatically adjust CPU computing power
to maximize system performance. C.I.A.2 allows your system bus to be changed dynamically
based on CPU loading through the use of 5 preset states.
Note: System stability varies, depending on your system hardware components.
Disabled
Cruise
Sports
Racing
Turbo
Full Thrust
Warning: Before using C.I.A.2, please first verify the overclocking capability of your CPU.
As stability is highly dependent on system components, when system instability occurs after
overclocking, lower the overclocking ratio.
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Options are dependent on CPU FSB. Auto sets
memory multiplier according to memory SPD data. (Default: Auto)
Memory Frequency (Mhz)
The first memory frequency value is the normal operating frequency of the memory being used;
the second is the memory frequency that is automatically adjusted according to the CPU Host
Frequency (Mhz) and System Memory Multiplier settings.
High Speed DRAM DLL Settings
Provides two different memory timing configurations. If your system becomes unstable after you
overclock the DDR2 memory, select Option 1 or Option 2 to help make your system more
stable.
Option 1
Option 2
DDR2 OverVoltage Control
Allows you to to set memory voltage.
Normal
+0.1V ~ +0.7V
Note: Increasing memory voltage may result in damage to the memory.
PCI-E OverVoltage Control
Allows you to to set PCIe voltage.
Normal
+0.1V ~ +0.3V
FSB OverVoltage Control
Allows you to set the Front Side Bus voltage.
Normal
+0.1V ~ +0.3V
GA-946-DS3/S3 Motherboard
Disables the use of C.I.A.2. (Default)
Increases CPU frequency by 5% or 7% depending on CPU loading.
Increases CPU frequency by 7% or 9% depending on CPU loading.
Increases CPU frequency by 9% or 11% depending on CPU loading.
Increases CPU frequency by 15% or 17% depending on CPU loading.
Increases CPU frequency by 17% or 19% depending on CPU loading.
Memory Timing Configuration 1. (Default)
Memory Timing Configuration 2.
Supplies the memory voltage as required. (Default)
Increases memory voltage by 0.1V to 0.7V at 0.1V increment.
Supplies the PCIe bus voltage as required. (Default)
Increases PCIe bus voltage by 0.1V to 0.3V at 0.1V increment.
Supplies the FSB voltage as required. (Default)
Increases FSB voltage by 0.1V to 0.3V at 0.1V increment.
