4GB on a 32-bit OS vs 4GB on 64-bit OS

ok lets say i buy 4GB ( 2x1GB) and i put it in my pc with my vista home basic. ( 32 bit )
should i do that or would i get a SIGNIFICANT performance using 4GB in a 64 bit O/S?
i read the other post about this and i didn't understand it. could someone explain it to me
the easy way? and if i plan on gaming would i be better off with 64 or 32bit? using 4 GB of ram

  1. if you don't have any old devices and old applications that you use, i suggest going to 64 bit.
    if you do have, 64 bit is not worth the hassle.
    32 bit vista can see memory up to 3.5 GB.
  2. 2x1gb =/= 4gb, thats basic math dude

    with 32-bit OS, you'll only register like 3.5gb of ram. so half a gb is useless

    with 64-bit OS, you can max out at like 128gb of ram. theres always room for more ram -_-

    and as far as im concerned, 64-bit is becoming more mainstream, and should really expand with multi core processors and such that are the norm now
  3. More memory = less time spent accessing the HDD

    I love my 8gb in Vista 64bit

  4. There will not be a significant difference in performance with 4gb under either 32bit or 64 bit operation.
    However, for $10, microsoft will send you the 64 bit DVD.
    You will get a more secure OS that can take advantage of more ram.
    Also, get that 4gb in a 2x2gb kit. It preserves your option to go to 8gb. and two sticls are easier to overclock than 4.
  5. Hasn't this been covered if you search "2gb vs 4gb vista"?

    10 bucks? wait are u serious? can you tell me how to do that? and where to order it from?
  7. that is for shipping and handling costs only and you must have Vista ultimate.

    anyways, for this topic this is tom's article

  8. correction there, not necessarily vista ultimate. i meant, full retail version of vista.

    Also applies to the the upgrade version which is considered retail. It costs about the same as OEM. There is a legitimate procedure for installing an upgrade version on a new machine.
  10. I wouldn't run Vista 32 bit in my system even if I had 4GB of RAM installed (so it would be seeing a little over 3GB of that, including the video card's memory as well I believe). Vista loves ram, I would only use it with the 64-bit version and 4Gb otherwise I'd use XP 32-bit.

    For whatever its worth I noticed a huge increase in performance for FSX when I went from 2GB to 4GB. But then realized I was having issues with 4 1GB sticks and had to move to 2 2GB sticks. All is well and it is always better when you get 2 bigger sticks rather then 4 smaller sticks. Corsair even warned me about this and said it takes more time going back and forth from 4 sticks then when you just have 2.
