I have 4 gig but it shows 3.12gb ram

[Pr0]

I just installed 4x 1gb of ram in each slot when i load xp it only shows 3.12gb of ram how i thought windows xp pro allows 4 gigs max.

 

[kof2000]

to fully utilized 4 gb of ram you will need a 64bit os.

 

[Pr0]

no kidding? i thought 4 gigs works on 32bit edition too

 

[kof2000]

try disabling virtual memory.

 

[Pr0]

On windows xp pro how you disable it?

Your system can't address all 4GB of RAM. Disabling virtual memory wont make all 4GB addressable. You can try enabling PAE http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx

HOLY CRAP NICE FIND! tell me if it works

As others have said, using Windows XP x86 only allows you to use up to 3.5GB of RAM.

It doesn't read all 4Gib.

wait, I'm confused...i though we were talking about 32biit,not 84...

 

[Cromewell]

We are, it's XP 32bit. Technically x86 (IA32) can be 32bit or 64bit now although it originally was to be 32bit only.

I added the /PAE in the boot.ini file but didnt see the 4 gigs

what about windows vista 32bit edition will 4 gigs work on that? If so will it be safe to get vista 32 bit? have anyone use it? is it better then xp pro?

At one time i had 1,768mb in my computer and XP and CPU-z read it as 1,792mb for some reason. It confused me.

I have vista home premium 32 bit and I was looking to upgrade to 4GB, but I called up HP before I decided to order and they all said 32 bit OS's can only handle upto 3GB. So then I googled it to find out that most can get 3.25GB to 3.33Gb but thats it.

I guess Ill have to just use the 64 bit edition of vista

 

[heyman421]

or just return a stick.....

i'm doing just fine with 1 gig, i would think 3 would be more than enough

 

[Pr0]

Whats the max amount of ram does windows vista 64 edition uses? if it uses 8gigs max then my 4 gigs was not enough for my future upgrade which is

quad core cpu = 1 gig for each core.
2900xtx or the 8800gtx

and better psu

 

[kof2000]

16 gb or something around that area.

I was thinking about doing the same thing, but i've found out that a lot of drivers don't work with the 64bit OS for a while so I'd wait a few months and be happy with your 3.12GB until the drivers issues are over.
