Foxconn P9657AB
3. Bios
The BIOS is from Phoenix:
In the "CPU Feature", we can disable SpeedStep and allow overclocking capabilities:
In the "FOX Central Control Unit", we can control all the major functions of the board. For our tests, we will set all functions manually, over-riding the auto settings:
FSB can be range from 266MHz up to 600MHz. We will see later on if this is achievable:
The North Bridge chipset controls DRAM. By default, all settings are at Auto. But users can take control and adjust the memory timings for better performance:
DRAM System Memory Frequency has 4 settings to choose from, SPD to DDR2-800MHz.
Each setting represents a different FSB:RAM ratio, so be careful what you select:
- DDR2-533 (1:1)
- DDR2-667 (4:5)
- DDR2-800 (2:3)
Memory, CPU, FSB, NB, SB and ICH voltages can be set according to the following table.
BIOS Setting | Feature: |
---|---|
CPU Clock Multiplier |
Not possible to set |
CPU bus frequency |
266 to 600MHz in 1MHz steps |
CPU voltage |
Normal to +0.3V in 0.0125V increments |
DRAM voltage |
Normal, -0.15V to +0.6 in 0.05V increments (2.4V max) |
PCI Express frequency |

Normal, -0.12V to +0.24V in 0.04V increments |
FSB voltage |
Normal, -0.09V to +0.18V in 0.03V increments |
If you overclock the CPU core, here is a suggested configuration:
Hardware monitor is useful to see how hot your CPU runs:
