What is the difference between Windows XP 32bit and 64bit???

Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. The reason I want to know is....

    I have an ASUS M2n32-SLI deluxe motherboard, capable of handleing 8Gb of ram, I have just replaced the 2Gb (2x Paired 1Gb Corsair DIMM) with 4Gb (2 x paired 2Gb OCz DIMM) and the computer is not recognising the upgrade.

    When I go into the FAQ part of ASUS website it tells me that this happens using the 32bit edition of XP but not the 64bit.

    Is it possible to change mine to 64bit??

    What would I have to do, do I have to buy a new edition etc????

  3. Ahhh right.

    I have an AMD processor so I will not bother then.

  4. If you are just going to use it for gaming I would not bother. I have the x64 version at home, most of the time it's ok but occasionally it struggles to find new drivers & run some older games.

    However, the 64bit OEM pack was 10 quid cheaper than the 32bit version.
  5. The other obvious choice is upgrading to 64bit Vista (now there's way to start a new debate...).


    Neither XP nor Vista can address the full 4Mb RAM in their 32bit versions - not MS's fault, it's just not possible.
  6. In addition to batus_survivor's post. If you right click My Computer > select properties. You'll usually see around 3.25Gb of Ram when using a 32 bit operating system with physically 4Gb ram installed. This is because windows XP32 bit can address a maximum of 4Gb of ram (the same as all 32 bit OSs), but some of that address space is taken up by the graphics card so you'll "see" 4Gb minus the amount used by the graphics card. Win XP 32 bit will utilise a maximum of 2Gb per application if memory serves me (no pun intended).

    To make full use of your new ram you'd need a 64 bit OS. However, Win XP 64 is not well supported 9drivers and such) and it would imho be a backwards step from Win XP 32. If you are using programs regularly that can utilise the increased amount of memory and want to go 64 bit then Vista is a far better bet than XP 64.
  7. Thanks for that, G, even I understood that explanation...I think!

  9. That's a bad singular stutter there, mate!

  10. There are only 10 sort of people that can understand binary, those who do and those who don't.
