right ok basically i want a step by step guide on how to overclock this particular processor a little bit, not like massively but i just want to know how to squeeze a bit more juice out of it

im a mechanic by trade so im capable at swinging spanners but this electric thing im not 100% at (confident though)

the mobo is an asus m4a78lt-m and the processor is as the title would suggest an athlon quad 640

thanks a lot!

this motherboard comes with overclocking utilities built into its bios, so during boot-up look for the thing saying hit something like F2 to configure or access bios, then i don't know how it's set up but look for the cpu options in the menu navigating with the arrow keys to find the stuff, there may be a tutorial on youtube or something so i'd look there first, possibly pull it up on a laptop beside you to watch as you do to avoid forgetting something, and make sure to use small incraments to avoid a crash, and check what other people get, but each processor does it differently so start a good 15-20 mhz below that and check stability, then go up a little, check stability, and do it over again until you hit the limit, then lower the mhz like 5-10 to be safe, that's just what i do.
 
With a Athlon II, you have to use the Bus to overclock. Which means it will overclock your HT and memory. If your wanting to go for all its worth, you need a good cooler. Plus you will need to adjust working with your memory and HT speed and voltage on top of your CPU Bus and voltage.

If you just have a stock cooler and want to do it easy.

Bump back your memory(say if your running 1333, bump it back to 1066)
Bump back you HT multiplier to 8
Set your CPU voltage to 1.4V, not any higher on a stock cooler.
Then start raising your CPU Bus a few MHZ. at a time till it gets unstable. Then back it off a few MHZ.
Then run a stress test on it.
 
cheers guys

when you say stock cooler, what exactly do you mean because the fan and heatsink i have is one of the copper pipes ones with the extremely large side draught fan and heatsink, and its never had any different so hats stock for me may not be whats stock for you
