E8400 3.6ghz to 3.8ghz problem.

First off Hello all,

I have been learning about overclocking over the few week and I'am starting to get the hang of it, however I need some help. I can't seem to get my E8400 over 3.6ghz? Here are my specs. Can you guys give me some advice on my timings or voltages perhaps which might be holding me back? Thanks in advance! :)

  1. Could you be more specific about what keeps you from going above 3.6GHz? Stability failure? Overheating? What exactly?
  2. stability failure I would say. If I set it to 3.8 or 3.7, when I look in CUPID it still says only 3.6 and I find that very strange. I've oc'ed my Ram to 750mhz now but still no change. However if i go in to my Nvidia tools to overclock, if i set the cpu to 3.8 my screen will just freeze and i cant do anything. I've tried higher voltages, but still no change. My temprature's never go above 60% either.
  3. I think you are overclocking your RAM and that is stopping your CPU overclock.

    Look at the CPUZ RAM timings. They are way faster than your FSB.
  4. what should they be do you think?
  5. could you post the model of your RAM ?
