Strange. 3gb of ram of 4gb?

[dangel]

I already triple boot - XP, Vista 32 and Vista 64. On one drive. No problemo.

If you are using a *retail* copy of Vista Home Premium, Business, or Ultimate, you can obtain a 64-bit disk from Microsoft for just the cost of shipping (Ultimate comes with it in the box). Now, correct me if I'm wrong, but couldn't you then install the 32-bit and 64-bit versions on your disk without purchasing another Vista license? I mean, its legal (I believe) to isntall your 32-bit Vista multiple times o nthe same computer (though why you would, I don't know); can't you do the samne with a 32-/64-bit combo, espeically if you bought Ultimate retail?

If so, thats what you should do; it'd be the best of both worlds. You would still have the 32-bit Vista for things that won't work correctly in 64-bit.

Yeah you probably could.
I'm sure i read somewhere that the 32-bit and 64-bit license codes don't differentiate eachother. I think i read that about OEM copies aswell. So the CD-key is valid for either 32 or 64bit.

so it's basically just wasting the other 700mb or so then?

I'll try get ahold of a 64bit vista soon i guess.

Damn

You should be happy... My 32bit XP only reads 2.75 GB out of 4GB!

If you add "/PAE" on your boot line it will then show 4gb of ram, this doesnt actually change how it uses it unless your specifcally using PAE support apps.
SQL/Exchange server etc.

IF its reading 2.75gb then im guessing thats a mobo issue not a windows issue, try PAE and see ifit changes.

Goto system properties > advanced > startup and recovery > edit
And it should say something like
"multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
just add /PAE to the line as well reboot
then on system properties tab at the bottom right where it shows ya ram it should say now
