Gigabyte GA-G33M-S2H mATX Motherboard Review

BIOS Features (cont’d)

 
The PnP/PCI configurations section allows users to set the IRQ assignments and control other resources. Only advanced users should make any changes to this section. Here are the IRQ assignments used by the Auto setting:

PCI1 IRQ Assignment: Auto BIOS auto-assigns IRQ to the first PCI slot. (Default)
3,4,5,7,9,10,11,12,14,15 Assigns IRQ 3,4,5,7,9,10,11,12,14,15 to the first PCI slot.

PCI2 IRQ Assignment: Auto BIOS auto-assigns IRQ to the second PCI slot. (Default)
3,4,5,7,9,10,11,12,14,15 Assigns IRQ 3,4,5,7,9,10,11,12,14,15 to the second PCI slot.

 
The PC Health Status section showed detailed information about a variety of options including system temperature, CPU temperature, CPU fan speed, and system fan speed. It also allows users to set the CPU warning temperature, fan fail warnings, and smart fan control methods and modes.

 
The MB Intelligent Tweaker section is where many users will notice significant differences between various motherboards. Some will have more options available, while others may only have a few configurable options. This particular BIOS has quite a few options for overclocking the CPU and memory. To enable most of these options, users will need to press Ctrl + F1. This is only necessary with Gigabyte motherboards.
 
The Robust Graphics Booster helps to enhance the performance of the graphics chip and memory. The Auto option allows the BIOS to automatically set the RGB mode based on system configurations.

 
The clock control feature controls the CPU host clock. When enabled, it will allow the CPU Host Frequency to be configured.

 
The CPU Clock Ratio feature allows users to change the CPU clock between 6 and 9. Most Intel processors have a locked CPU clock, but the Extreme Edition processors have unlocked processors that can be configured to increase the performance levels of the CPU.


This option allows users to set the system memory multiplier. Options are dependent on CPU FSB. Auto sets memory multiplier according to memory SPD data.
 

To configure your RAM’s individual timings, users will need to set this option to manual. Since the board only supports up to DDR2-800 on Auto, most users with higher-rated memory will need to set this option to manual and manually change the timings to match the RAM they want to use.

 
Lastly, users can also configure how much voltage they want to use to overclock their CPU and memory. This board allows users to modify the RAM, FSB, MCH, and CPU voltage.
