ok...here are some things to get you started...
when you enter bios, press CTRL+F1 to unlock all bios options
disable EIST and C1
set everything from auto to manual
find the pci express lock and set it at 100mhz
set the ram ratio at 2.0 (1:1)
set your timings to the default timings used at 800mhz (it should say on your ram box or search the net to find that out if you don't already know)
now when you've got all that covered, leave the multiplier at 9x and leave all the other voltages like vRAM, vFSB, vMCH, vPCIE at normal and just change the vCore from auto to 1.3250v (this is stock voltage for your cpu)
after all that you should be set to start rising the FSB in 20 by 20mhz increasement, when you reach 300mhz FSB, go with 5 by 5mhz
for monitoring purposes, use CPU-Z to read the core speed/fsb, memory timings/ratios and frequency under memory tab
use core temp, everest or speedfan to monitor the temperature (disregard the cpu readings and concentrate on the core0 & core1 temps) and voltage
you can also use cpu-z for voltage readings but it might have some problems reading it so use it only if it's readings correspond with the other programs
use orthos for stability testing and if your cpu becomes unstable (probably will after ~310mhz fsb) start adding a little voltage, just upp it one setting higher (first one possible in the bios) and check for stability again
you're good up to 1.45v in windows, remember that idle voltage is what you're looking for because it will always drop a little when your pc is under load
also, watch out for the temps, you shouldn't let it go above 61c while under load
