BIOS and Overclocking
Now we take a look at the BIOS and the overclocking potential. Using the latest BIOS, which at time of release was S1.3 (dated April 25th 2006), you get a good amount of overclocking and tweaking features for a Micro ATX based value board.
The Foxconn 6150K8MD uses an Award 6 BIOS that resembles just about every other board using this same BIOS. Foxconn places its major overclocking and tweaking features under the Advanced Chipset features and the BIOS features menu.
Once you enter the BIOS Features menu, to gain access to the overclocking features you need to open up the SuperSpeed sub menu. Once there you get the majority of the clocking features.
Once in the SuperSpeed menu you will need to concern yourself with the last few options for the overclocking. Hammer FID controls the CPU multiplier. You can adjust them from 4x up to the maximum of what your CPU supports - in the case of our 4200+, it was 11x.
DIMM voltage is a little under powered with settings from 2.60V up to a maximum of 2.85V in 0.05V increments. VCore Voltage select is used to change the CPU voltage supply - options are from +20mV to +140mV in 20mV increments. Speaking in normal terms you can adjust the CPU voltage from its default to a maximum of +0.14V above standard. Lastly on the voltage front is the chipset voltage. Voltage is either +50mV or +100mV.
To get to the bus overclocking you need to enter the Performance Option Sub Menu. Once you enter you are faced with two extra options. First is the CPU Frequency. This can be adjusted from 200MHz to a maximum of 450MHz in 1MHz increments.
Lastly is the PCIE Clock with adjustments from 100MHz to 145MHz in 1MHz increments. For best results it is advised to leave the PCIE clock at 100MHz.
For the rest of your tweaking options you will find under the Advanced Chipset Features menu. Here you can adjust DRAM clock and timings as well as adjustments to the Hyper Transport links from Northbridge to CPU and Northbridge to Southbridge. Frame Buffer size for using the onboard Graphics can be selected at 16MB, 32MB, 64MB or 128MB.
With all the settings here we managed to get an FSB of 252MHz with the CPU running +100mV, DRAM at 2.8v, chipset voltage at standard and all HT links all running at 3x.
