More about what ganged mode turn
  1. I've seen it explained as below:
    Ganged = dual channel mode for ram. All cores get access to 100% of the ram.
    Unganged = single channel. Each core gets access to a stick of ram. In theory, the unganged mode is better as each core will get access to data quicker. Also, it also allow you to control the clocks independently from each other.

    I would run unganged for an AMD build, as it seems to run better from my experience.

    Edit: Here is a nice article on this topic for your review and enjoyment :)

    On PAE, here is a nice article about it for your review:

    The thing I would take out of the article is the concern of stability by making your "32-bit system" into a "64-bit system". I would recommend against it. If this is something you truly want, I would do a Google search on how to or hopefully a member will post you directions on how to do it.
  2. Thanks. :) I turned on PAE and I still only have 4gb RAM, why? :heink:
  3. How much RAM have your installed in your PC? If you are only seeing 4GB but have more than that installed, there might be issues steaming from PAE. If you only have 4GB and it sees 4GB, you are good to go!
  4. I have 4gb installed but it only sees 3gb, why?! I have PAE on. :cry:
  5. If I'm reading this link right ( http://msdn.microsoft.com/en-us/library/aa366796.aspx ), it gives applications the ability to use more than 4GB of RAm but your 'Windows' properties screen will still show the same as with the 32-bit system.
  6. Cool, I did that and it still shows 3gb. Does it just show 3gb and I am really using 4gb?
  7. Yes... When applications require more memory, you are using all 4GB. This is how I understand it at least :)
  8. Cool. Thank you for all the help.
