Setting CPU Voltage and Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on. However, if users are willing to do overclocking,
we also provide a range from 0.80V to 1.80V in the BIOS. Sometimes increasing
the original core voltage a little bit will make CPU overclock more properly.
Setting CPU Frequency
This motherboard is of CPU jumper-less design; you can set CPU frequency by
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio . However, all CPU now sold in market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but change CPU FSB
clock to achieve overclocking only.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
(Users will do the overclocking at their own risks!!)
CPU Ratio From 4x to 25x step 1x
CPU FSB (Adjustment
manually)
FSB = 200 MHz-250 MHz by 1 MHz Stepping CPU Overclocking
AMD CPU CPU Core Freq. CPU Clock L2 Cache Ratio
Athlon 64 2800+ 1800MHz 200MHz 512KB 9x
Athlon 64 3000+ 2000MHz 200MHz 512KB 10x
Athlon 64 3200+ 2000MHz 200MHz 1024KB 10x
Athlon 64 3200+ 2200MHz 200MHz 512KB 11x
Athlon 64 3400+ 2200MHz 200MHz 1024KB 11x
Athlon 64 3400+ 2400MHz 200MHz 512KB 12x
Athlon 64 3700+ 2400MHz 200MHz 1024KB 12x
Note: With CPU speed changing rapidly, there might be faster CPU on the
market by the time you received this installation guide. This table is kindly for
your references only, please contact with your distributor for more information
Note:
If your system hangs or fails to boot because of overclocking, simply use
<Home> key to restore the default setting or you can wait the AOpen “Watch Dog ABS”
reset the system in five seconds and system will auto-detct hardware again .
Warning:
VIA K8T800
chipset supports
maximum
200MHz system
clock and 66MHz
AGP clock; higher
clock setting may
cause serious
Warning:
Supposed you have had adjusted CPU ratio on your current CPU,
and you plan to replace a new CPU. Please use <Home> key or Clear CMOS to restore
the default setting when changing a new CPU, because the system will still implement
the previous CPU setting on the new one.
