Best way to overclock athlon ii x4 640??

hey
what and how is the best way to overclock my athlon ii x4 640? (currently at 3.0Ghz standard)
i know there's a few programs out there to use, i've done some research, obviously if i overclock i need to keep my eye on the temperature, but then there's something about BUS speed? (not sure what this is) also my ram is only 667mhz, i'll need higher i think such as 1066?

many thanks

    I would not use those software programs, if you are going to overclock do it right and use the BIOS. You have to go into the BIOS and make slight, incremental change to the frequency. Keep doing that and after each increase run Prime 95. Once you hit a wall and can't get it to be stable ease back on the overclock and do a full stress test for aleast a full 24 hour period.
  2. Multipliers too, NEVER USE A PROGRAM.

    thank you, is there anything else i need to know/do? like anything to do with the bus speed? also my ram is 4GB (2 x 2GB) but its only 666.7 MHz, would that be ok?

    hey, what do you mean by multipliers?
