We used BIOS version 0403 for this roundup.
|Bios Voltage Settings|
|FSB frequency||100 - 450 MHz (Bios settings)|
|CPU Core voltage||1.200 - 1.700 V|
|Memory voltage||1.80 - 2.40 V|
|FSB Signal voltage||1.20 - 1.50 V|
|Northbridge (MCH) voltage||1.50 - 1.65 V|
|Sourthbridge (ICH) voltage||1.05 - 1.20 V|
If you run this motherboard at FSB800 speed (200 MHz), memory speeds up to DDR2-800 may be selected, although the chipset is only specified for a maximum of DDR2-667.
At FSB1066 (266 MHz) you could deploy DDR2-1066 memory.
Asus allows you to modify certain processor parameters.
The option "Hyper Path 3" helps to increase the memory bandwidth.
|Possible Memory Configration|
|FSB1066 (266 MHz)||1:XX||FSB800 (200 MHz)|
The BIOS offers an item called "Performance Mode". If you set this to "Turbo", the motherboard will increase the FSB speed by 2 MHz, but without telling you about it at boot time. In order to ensure a fair comparison, we used the "Standard" setting.
Asus provides a graphics overclocking feature called "PEG Link Mode". "Slow" does not change anything and runs the graphics card at default speeds. All other options will automatically overclock the graphics card by a noticeable margin.
