MoBo: Biostar A780L3

Any help would be appreciated :)

First, don't expect much performance improvement from any OC, because the CPU has a locked clock multiplier. You have to get all your OC by increasing the FSB (base clock). (MHz = FSB x clock multiplier) You're only looking at a few 100 Mhz at most, and then only if the motherboard and PSU is designed to accept the increase in stress, and you have an after-market cooler. ** If your motherboard's power transistors (VRM) do not have heat sinks, I would not attempt to OC. **

Enter BIOS and begin raising the FSB in small increments. Save, exit to Win, and run a stress test like Intel Burn Test using its default settings. If it passes and core temps are safe (< 75C), repeat.
Eventually, the core voltage (vcore) will need to be increased when the OC is no longer stable. Take the vcore up in small increments (0.025 - 0.050v) and test again. Max vcore should stay below 1.500v.

As you increase the FSB, you are also increasing the operating freq. of everything else that runs off the FSB. Most importantly, the RAM speed. So, you should lower the RAM speed before you start so that it doesn't become unstable and give you a false test result.
