AlanHo Posted October 7, 2009 Report Share Posted October 7, 2009 I have pre-ordered 2 retail versions of Windows 7 Home Premium for installation on both our home computers. Both computers are modern with Intel Quad processors and 4 GB RAM.I am assuming that the Windows 7 installation DVD allows you to choose between 32 and 64 bit installations.If I decide to install the 64 bit version - and then find that there are unresolvable incompatibility problems with my peripherals or software - am I allowed to uninstall the 64 bit version and reinstall as 32 bit?

D4\/!d Posted October 7, 2009 Report Share Posted October 7, 2009 I have partitioned my hard drive.On one partition I run Win 7 x86, on the other Win 7 x64 (and on the third Win XP Pro)I triple boot.To be honest I have only really used the x64 - now my default - for most of this year.Sorry, it doesn't answer your question but it saves you making that decision about which version and can I change.

AlanHo Posted October 7, 2009 Author Report Share Posted October 7, 2009 I had already sussed that my computer is OK for 64 bit and that most software is compatible. Hence I would like to give 64 bit a whirl in order to increase my RAM beyond 4 (3.25) GB.However - I will only do this if I am assured I have a free escape route back to 32 bit Windows 7.On another forum it has been suggested that you can install Windows 7 without entering the serial number and without activating it. This gives you 30 days to try it out. If this really is the case - problem solved - but I would like a second opinion. Quote Link to comment Share on other sites More sharing options...

Hence I would like to give 64 bit a whirl in order to increase my RAM beyond 4 (3.25) GBBy the way, I have a 64 bit version of Vista but I can still only use up to 4 GB of RAM because the motherboard chipset has a memory limit of 4 GB :(Had I known this then I would have bought a better spec of PC but it is still able to play all the latest games and my 4 GB limit won't be an issue for a few years I suppose and by this time I will probably be using a new PC anyway :D http://www.foxconnchannel.com/product/Moth...id=en-us0000345Dual channel DDR2 800/667 x 2 DIMMs, Max 4GB Quote Link to comment Share on other sites More sharing options...
AlanHo Posted October 7, 2009 Author Report Share Posted October 7, 2009 I built my latest computer quite recentlyMobo ASUS P5QL-E - IP43, Socket 775, will support 16 GB RAMIntel Core 2 Quad Q9650 3.0 GHz, 1333 Fsb, 12 MB cacheASUS GF8600 GT 256 MB graphic cardI guess this will easily do justice to 64 bit Windows.I really don't expect to see a great deal of diffemce operationally - except on video editing. I do not play games on the computer (only in real life)... Quote Link to comment Share on other sites More sharing options...
