1. Yes, you can flash your bios with winflash. Just be sure you don't use the utility the motherboard came with to flash your bios. All the settings below worked for me with the 01/19/2006 Foxconn bios.

2. In your bios go to BIOS FEATURES press enter. This is the second option in the main BIOS menu.

In the BIOS FEATURES menu go to the fourth option SUPERSPEED press enter.

Here you will get a few choices the most important being:

A. PERFORMANCE OPTION----->CPU FREQUENCY----->This can be set between 200 to 450, but you will not be able to go beyond 275 in the bios.

B. HAMMER FID CONTROL--->This option controls the cpu's multiplier. You can probably set yours from 11 on down to 4. Remember CPU FREQUENCY X HAMMER FID CONTROL=CPU SPEED! I would probably set this to 10 and try for 250 on the fsb.
EXAMPLE: 250Mhz X 10 = 2.5 GHZ

C. HAMMER VID CONTROL--->This option controls your cpu's core voltage. You should probably leave this setting alone if you don't plan to overclock too much.

D. VDIMM VOLTAGE SELECT---> You will probably want to leave it at default for now.

E. VCORE VOLTAGE SELECT---> This setting adds an adjustment to your HAMMER VID CONTROL. So HAMMER VID CONTROL + VCORE VOLTAGE SELECT = CPU VOLTAGE
EXAMPLE: 1.344v + .020mv = 1.364v


3. Go back to the main BIOS menu. From here choose the 4th option ADVANCED CHIPSET FEATURES. Once in the following menu you will get a few more choices:

A. DRAM CONFIGURATION---> This will let you adjust your ram timings and divider.
Under DRAM CONFIGURATION set the options TIMING MODE and USER CONFIG MODE to manual. TIMING MODE will let you set your fsb/ram ratio to 1:1 by setting it to 200. USER CONFIG MODE will allow you to set your COMMAND RATE to 1T or 2T.

B. K8<->NB HT SPEED---> You will have to set this to 4 if you plan to overclock even a little over the default 200 CPU FREQUENCY.

C. NB-->SB HT SPEED---> Same as above

D. NB<--SB HT SPEED---> Same as above
