Overclocking Athlon II X4 420 On Budget Motherboard?

Hi, I was wondering if it is possible for me to overclock an Athlon II X4 2.6 GHz up to 3.2 GHz on stock cooling using a motherboard with the following chipset: 770/SB710. The motherboard model is Asus M4A77TD.

Thanks in advance. I am trying to decide on what to do with my first build and this seems like a good and fun idea :).

  1. Its possible the cooling will most likely be the thing that decides so make sure you keep an eye on the temps.
  2. Overclocking any cpu on the stock cooler will limit how far you go very quickly. I would say getting an extra 300 to 400mhz on stock cooling is possible if your ambient temps aren't too high. If you can save up $30 to $50 down the road, a decent aftermarket cooler would be well worth it. Provided your case can accommodate a large cooler !!!

    With that said, I have the M4A77TD and a x3 435, it is a very capable motherboard for overclocking. If by x4 420 you mean the x4 620, yes it's possible to reach 3.2 maaaybe more with a good cooler. At $82, I would recommend the newer C3 x3 445: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103872&cm_re=19-103-_-19-103-872-_-Product Paired with some decent 1333, A/M cooler and a good psu, it would be possible to reach at least 3.5,3.6 easy, possibly more. (There also is the slight chance you could unlock it to a x4 with that MB...)

    Here is a comparison between the 3.0 x3 440, (not 3.1 x3 445) and the x4 620 at stock clocks: http://www.anandtech.com/bench/Product/119?vs=106

    mishima, I have the same CPU as you do currently (if you meant to say 620) and with my ASUS M4A785TD-V EVO (785 chipset) I was able to get a 3.25GHz overclock with the following:

    FSB: 250
    CPU Voltage: 1.3v
    NB Voltage: 1.25v (I think)
    CPU Multiplier: 13x
    RAM Timings: 9-9-9-24 (or 27 - can't remember, but it was at stock settings)

    This was done with the stock heatsink; however, when I ran Prime95 temps went up to 63 degrees Celsius during an hour of doing that (61 degrees average), then I quit it because I'm not crazy about the idea of heating my room up while this test runs overnight lol.

    Sorry that I didn't answer your question directly, but maybe it might help?
