  1. Hello, and welcome to THG.

    If it is the same chipset, it should be compatible. Here:

    If you want a quad core option, if your motherboard allows it,( check with dell first):

  2. I am in the same situation. Are you sure the BIOS upgrade will work with the E7600 Wolfdale?

    I am looking for just a straight swap out of the processors.
  3. No I am not. I have searched through other forums and I couldn't find another reference to that specific CPU working with the E520. I just wanted to be sure before dropping $150.

    Thanks for your help. If you know of any forums where someone has done the swap to that CPU, please let me know.
  4. You can run a q6600 or a q6700 as well as the qx6600 and the qx6700 on an e520 with the latest bios which is 2.4.0. i wouldnt suggest the qx series being that you wouldnt have much use of the features of that processor being the dell locks out overclocking features!!
