Overclocking Athlon X2's

Hey all, I'm currently overclocking my Athlon X2 4200. So far I have got it sitting pretty at 2.5ghz (stock 2.2ghz). Current settings are 250 x 10 bus, x4 HT, and a 166 divider on the RAM. This gives me my 2.5ghz operating speed, 208mhz (Near PC3200) ram speeds, and a HT link of 1000mhz.

The thing is, I believe I can push this machine further, and was just wondering how I would best go about doing it. I was thinking of dropping the HT down to x3 to give me more headroom in upping the bus past 250. But this would put my HT link down in the region of 800 odd (as opposed to 100), will I lose much speed because of this?

Any advice you could give would be grand. Cheers!

    No, it won't affect things noticeably, the increase in frequency more than covers that.
  2. 'Hokay. I am now standing at 2750mhz on the CPU. I have only Prime95'd it for an hour whilst I was out running, but it seems to be stable. I'll run a torture test for 6 hours tommorow, when I'm at work. PCMark 05 currently shows nearly a 1000 point increase over stock. I like!

    So, do you reckon I could get it any higher (safely) - maybe towards the 'big 3' mark? Temperatures are currently between 35 and 40 idle, with it going upto about 45 under load (*c)

    Cheers.

    I would say, if you bump the voltage a tad, you might get another 100MHz. GL
  4. in my sad case, my new 4200x2 wont overclock past 220 even with voltaje (sometimes handles 229) but crashes soon


    ive easily gotten semprons to 268 bus i supose my 4200 is maxed out already at stock

    one cant lower the clock multiplier on AM2 right?
  5. You're doing good. On the 4400+ that I had, I went a slightly different route of a 260 x 11 bus for 2860 mhz. I put on a Zalman 9500 and the heat stayed always under 50c, usually topping at 48c while running both Prime95 and 3DMark06. Your 4200+ is similar, so you should have room for more. I did have to raise the voltage to 1.45v, so if you haven't raised it yet, you might have to in order to stay stable.
