first off, you need to verify that your mobo can overclock the CPU without overclocking the PCI/AGP bus as well, if it can't then you won't be able to get anything out of it.
to overclock you need to understand how your speeds are determined.
1. BUS (or FSB) = system speed (external CPU speed)
2. HTT (hypertransport bus) = direct link from CPU to memory
3. CORE CLOCK = CPU internal speed
4. CPU MULTIPLIER = determines CORE CLOCK speed when multiplied by the BUS
5. HTT MULTIPLIER = determines HTT speed when multiplied by the BUS
6. RAM DIVIDER = determines RAM speed when divided by the CORE CLOCK
here is your default settings as a reference:
1. BUS = 200MHz
2. HHT = 800MHz (1600MT/s via DDR)
3. CORE CLOCK = 1.8GHz
4. CPU MULTIPLIER = 9
5. HTT MULTIPLIER = 4
6. RAM DIVIDER = 0
once you understand those terms and what they do, it's pretty easy. but you should keep a few things in mind:
1. try to keep the HTT as close to 800MHz as possible (if it's a little less that's OK, but don't overclock it alot).
2. you cannot raise the CPU multiplier above 9, so the only way to overclock it is to raise the BUS
3. your RAM may not be able to run as fast as the BUS. for instance if you raise your BUS to 250MHz, you also raise the RAM speed to 250MHz, some RAM can run at that speed, some can't. if your's can't then you will need to set a RAM divider to bring it back down around 200MHz.
4. DON'T RAISE THE V0LTAGE ON ANYTHING UNTIL YOU'VE REACHED THE MAXIMUM STABLE OVERCLOCK ON DEFAULT VOLTAGES. OVERVOLTING CAN FRY YOUR COMPONENTS. only raise the voltage if you are willing to risk frying your components. that being said, if you decide to raise the voltage, use the smallest increments possible.
start off with a small overclock by raising the BUS to 220, save and reboot. if it boots then you just overclocked your CPU by 180MHz. to go higher you will likely have to lower the HTT multiplier and set a RAM divider, but see what you can get without that first.
P.S. if it won't boot, use the CMOS jumper to set the BIOS back to defaults.
good luck
