you need to go and download coretemp for temp readings and prime95 for stability testing and cpu-z to check the clock details and what your vcore drops to under load..
get core temp / cpu-z running then load up prime95 and select just stress testing.. you want to run small ffts to stress the CPU clock.. make sure in the advanced menu you select enable error checking... run prime95 and keep an eye on your temps (under 75c is acceptable)
probably want to run it for 15 mins for each clock until you get to the speed you want and then run it for a good few hours.. if the pc crashes or prime95 reports an error on one of the cores stop the test and go and up the vcore in the BIOS by one notch..
Before you start any clocking set some stuff manually in the BIOS...
DRAM Voltage: Set to manufactures recomendations
DRAM Frequency: Needs to be under 1066mhz
DRAM Timmings: 6-6-6-23 for now you can tighten them later once you have a CPU clock
FSB to Northbridge Strap: 333mhz
CPU PLL: 1.5v
NB Volt: 1.4v
VTT: 1.4v
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
LoadLine Calibration: Enabled
PCI-Frequency: 101mhz
vcore: set to your CPU's VID (this is shown by coretemp)
check that its stable at those settings and then start raising the FSB from default
