CPU Vcore
This field displays the core voltage supplied to the
CPU. If you want to set it manually, always refer to
the CPU documentation. The pictures shown here pro-
vide only examples of possible Vcore ranges.
SDRAM Frequency (MHz) [Auto]
This feature tells the clock generator what frequency to send to the SDRAM. The
default setting [Auto] seeks to balance optimal performance with stability. The other
options displayed in the popup menu vary according to the CPU External Fre-
quency. The first value is the external frequency multiplied by 3/4 and the second
one equals the external frequency.
WARNING! SDRAM Frequency higher than 100MHz is beyond the system
chipset specification and may cause your system to be unstable/hang up.
CPU Level 1 Cache, CPU Level 2 Cache [Enabled]
These fields allow you to choose from the default of [Enabled] or choose [Disabled]
to turn on or off the CPU’s Level 1 and Level 2 built-in cache. Configuration op-
tions: [Disabled] [Enabled]
CPU Level 2 Cache ECC Check [Disabled]
This function controls the ECC capability in the CPU level 2 cache. Configuration
options: [Disabled] [Enabled]
BIOS Update [Enabled]
This functions as an update loader integrated into the BIOS to supply the processor
with the required data. In the default position of [Enabled], the BIOS will load the
update on all processors during system bootup. Configuration options: [Disabled]
[Enabled]
PS/2 Mouse Function Control [Auto]
The default of [Auto] allows the system to detect a PS/2 mouse on startup. If de-
tected, IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expan-
sion cards only if a PS/2 mouse is not detected. [Enabled] will always reserve IRQ12,
whether on startup a PS/2 mouse is detected or not. Configuration options: [En-
abled] [Auto]
