More than 4Ghz for AMD x4 955

Hello, so i overclocked the cpu to 4ghz. Multiplier x20 and voltage 1.40. My temps under load are max 45 degrees! Thats pretty chill, but i also have 6 fans in my case and 2 fans on the heatsink..

Will i see more performance if i clock it to, let say; 4.4Ghz or 4.2? Also, i only changed multiplier and voltage. Do i need to change other values like NB, etc.. for more than 4ghz?

More about more 4ghz
  1. thats plenty dont try any more.
  2. I wouldn't go any higher unless you have a high quality motherboard designed for what you're doing.
  3. Dunno if it will apply to you but i hit a wall at 4GHz, the further past that the more instable it gets, not to mention i couldnt get 4200MHz to boot on 1.6V where 4000MHz runs fine on 1.42
  4. Many Phenom II processors will top out at around 4ghz regardless of cooling.

    Depends... Going up by 200MHz is only a 5% and 400GHz is a good 10% increase. However, that does not mean everything will run 5% or 10% faster. The increase in performance will likely be 3% and 6%. For intensive CPU tasks like video encoding, then yes you will notice a small increase in performance. If you are talking about games, then the most likely answer is no unless you are playing a game that is really CPU intensive like Civilization 5 or MS Flight Simulator X, but even then the increase will be relatively small.
  6. You'll likely find more enthusiasm in the Overclocking Forum. :)
