I just did a clean install of Windows XP Pro x64 on my home computer and, after a bit of a wrestling match, got all the drivers working, everything humming, etc...
Might be late in the game to ask this question, but will the extra RAM I will be able to have the OS recognize be used by 32 bit applications or is it "invisible" to them? I know my 64 bit apps can use it, but say, if I am running 5 of the 32 bit apps, will they only be able to see up to 3.22Gb or RAM and then start using the paging file?

Re: 64-bit Question
Thu, May 7, 2009 - 1:13 PMAs a threshold matter I suspect that Unless you paid a fortune for the OS it is not 64 bit
I recall when I got my OEM disk of XP Pro People just took it for granted that it was 64 bit. So they spoke of that way to me and off I went thinking I had 64 bit. I was mistaken.
However that 64 bit OS is really expensive and the Win XP Pro is not 64 bit
To determine whether you have a Win XP 32 or 64 bit OS do the following
1. Click Start, and then click Run.
2. Type winmsd.exe, and then click OK.
3. When System Summary is selected in the navigation pane, locate Processor under Item in the details pane. Note the value.
............. * If the value that corresponds to Processor starts with x86, the computer is running a 32-bit version of Windows.
..............* If the value that corresponds to Processor starts with ia64 or AMD64, the computer is running a 64-bit version of Windows.
As to the RAM
It's prolly maxing out at 3.2 Gig.
Click the START button
run the cursor up to the "My Computer" icon and Right Click that.
Select "properties"
Read what it says.

Thu, May 7, 2009 - 2:28 PMIt's Windows XP Professional x64 Edition
I get discounts on OS and apps through work. I paid 8 bucks and got XP Pro and XP Pro x64, so i don't know if I would have paid a lot.
I did run winmsd.exe

Windows XP Professional x64 Edition
This edition supports the x86-64 extension of the Intel IA-32 architecture. x86-64 is implemented by AMD as "AMD64", found in AMD's Opteron, Athlon 64 chips (and in select Sempron processors), and implemented by Intel as "Intel 64" (formerly known as IA-32e and EM64T), found in some of Intel's Pentium 4 and most of Intel's later chips. It was released on April 25, 2005.[23]
Windows XP Professional x64 Edition uses version 5.2.3790.1830 of core operating system binaries, [24] the same version used by Windows Server 2003 SP1 (and Windows XP 64-Bit Edition version 2003) as they were the latest versions during the operating system's development. Even service packs and updates for Windows XP x64 and Windows Server 2003 x64 are distributed in unified packages, [25] much in the manner as Windows 2000 Professional and Server editions for x86.
During the initial development phases (2003–2004), Windows XP Professional x64 Edition was named Windows XP 64-Bit Edition for x86 Extended systems and later, Windows XP 64-Bit Edition for Extended systems, as opposed to 64-Bit Edition for Itanium systems.

Re: 64-bit Question
Fri, May 8, 2009 - 5:56 AMWell, with the release of Vista and now, the imminent release of Windows 7, the OSs i got have gotten fairly cheap. I think NewEgg has 64 XP Pro at 160 or so?
I've been hunting through the net on the advantages of 64 vs 32 (x86) architecture and I am not floored. The slowdown is in the software.
Luckily XP Pro x64 runs 32-bit programs just (mostly) fine. Antivirus is a big exception to that. I did find that AVG free works well with XP Prox64.
Oh, well, I will benchmark some software and see what's up.

Re: 64-bit Question
Thu, May 7, 2009 - 3:57 PMWhen I was chatting a Corsair Engineer about memory and offered up that XP might not see more than a couple gigs he told me that it'd report only three and a half but could really see more.
That was how he talked me into buying the 4-gig Dominator pak.
So maybe you really can use more than 3 -point-whatever.

Re: 64-bit Question
Fri, May 8, 2009 - 5:59 AMYeah, 3.23Gb is "the end of the universe" for RAM on a 32-bit system. Theoretically, a 64-bit system can recognize up to 128Gb of RAM. That is all well and good, but will programs not written for 64 bit architecture even know the extra ram (over 3.23Gb) is even there?
I have ordered another 4Gb for my comp and, by Jove, I'm gonna plop it in there whether it does anything or not!!

Re: 64-bit Question
Fri, May 8, 2009 - 11:15 AMI don't know why not. It's not necessarily the program that's directly using the memory. The OS allocates it and tells the programs where in memory to reside and store stuff.
If the programs were doing the allocating you'd have conflicts Galore when you ran more than one app.\
The programs have to talk to the OS and vice a versa
I am looking for an old school DOS box. I had one I thought would work but it failed cause of the inter faces on the mainboard
I gotta have old school mouse and keyboard inputs Otherwise the DOS legacy program I want to run won't work.
