DxDiag only showing 3200MB RAM

Hello, I have 4GB of RAM installed on my motherboard. However, when I run DxDiag, it's only displaying 3.2GB of RAM. Could it be that my bios needs to be upgraded in order to detect the full 4GB? I am currently using the default system bios. I have an AMD Athlon II X4 640 Processor 3.0GHz, and an ASRock M3A770DE Motherboard.

  1. Do you have a 32bit or 64bit operating system? A 32 bit OS can only "see" 3.25GB of RAM so likely that is your problem.
  2. I am not sure what bit operating system I have (I've been told, if I don't know, then I probably have a 32bit OS), but when I check system info, DxDiag, EVEREST, System Information for Windows, etc. it does not indicate what bit my OS is, it simply says "Windows XP Professional Service Pack 3".

    64 bit XP was quite rare so I am pretty sure you have a 32bit version. No worries 4GB will still help even if the OS can not see all of it.

  8. Ask away. I will help if I can.
  9. Is there any way to install windows 7 on my computer, whilst only having 1 hard drive with windows xp already installed on it? Like upgrade?
  10. I would do a clean install. Back up everything you need to keep to an external drive or a thumb drive or even a DVD or CD and then do a clean install of Windows 7 64 bit. There is no upgrade path from 32 to 64 bit.
  11. Okay, thanks. Is backing up different than "copying and pasting" all the files I want to keep? And, would I be able to keep my program files (my installed games) / would they be playable after I transfered them back after Windows 7 was installed?
  12. Backing up is just copying and pasting correct. Like any music or pictures you have. You would have to reinstall all your programs.
  13. Ahh. Okay, gotcha. That's exactly what I figured, I just wanted to confirm. Thanks so much for all the help. It's much appreciated. I now know what I must do to run Direct x 11.
