Specs: Microsoft Windows XP Professional, 2.31 GHz / 3582 MB
A few weeks back I did a RAM upgrade to my

I originally had 2 GB of ram and i purchaced 4
GB of DDR2. It all installed correctly. No major
problems. (There was the slight problem that
occurred when it didn't register as existing, but
thats dealt with now.)
This phisically left me with 6 GB of ram.

I booted up my computer and checked how
much it detected. It said 3.50. I checked it
with CPU-Z and it said 4096.
CPU-Z also told me that slots 2,3 and 4 were in use. My system must be ignoring slot 1.

Can any one explain why it does not detect 6
GB of ram? Is it because i need to reload
After I put in the new ram i installed a 64-bit
edition. But this still detected 3.50 GB of
All i could guess was that this was XP's limit.
Id check it with one of my other installed OS' but I have no clue how to.

Could someone please explain this to me in
detail? :
System information tells me i have a:
AMD Athlon(tm) 64 X2 Dual Core
Processor 4400+ 2.31GHz

What is the 4400 in this?
My first guess was that it meant i had a 6.71
GHz processor. But if thats the case, then
why are all factors pointing to me having a
2.31 GHz?

Thanks for this,
As you may have noticed. I'm not very good
with hardware... Or programming... Or
computers in general.

Here are what system tells me my stats are.
Plus more information i added just encase it helps.

Microsoft Windows XP 32-bit SP2
Microsoft Windows XP 64-bit
Microsoft Windows ME
DOS 6.22
Ubuntu LTS 8.04

AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ 2.31GHz

6.0 GB (System only detects 3.50 GB)

Graphics Card:
NVIDIA GeForce 8500 GT 512 MB

Hard Drives:
190 GB (internal)
500 GB (internal)
120 GB (external)

You state you installed a 64 bit edition but the information you posts states otherwise. Don't confuse your 64 bit processor with a 64 bit operating system.

All 32 bit OSes, including yours can ONLY configure 4GB of RAM. If you really need 6GB of RAM then you need to use a 64 bit OS. Even when you limit the installed RAM to 4GB you will not see the entire 4 GB. This has been discussed here many times. If you need more explanation search here or use Google.

What i mean by i installed 64 bit edition was that when i purchased my 500 GB hard drive i partitioned it as two partitions. One, as a 400 GB FAT32 that i plan to use for storage and the remaining 100 GB i used to install Windows XP 64-bit Edition. I then configured /boot/grub/menu.lst from my ubuntu installation (old 190 GB hard drive) so that i could boot 64 bit as well as the other operating systems on that list. (I know i could've used vmware. And i did, just not with the OS' on that list. I have freeBSD and Vista set up with vmware. I got kind of obsessive and just started purchasing windows operating systems. The dos was my uncles originally i think. It comes in handy every now and then.)

So i'm not really getting confused. And i did search Google. But strangely all i could find referred to a 32-bit installation of vista.
Thanks for your time but this doesn't really answer any of my questions.


EDIT: AKA; I checked how much ram was showing in 32-bit XP first. then 64-bit second.
Both gave the same result.

If you boot into the WinXP 64 bit your RAM should all show there.

As far as buying Vist 64 bit, look at the link below for a couple of options.

Why would you want all those similar OSes? Wait until Windows 7 is released to buy anything more.

Thanks for the idea - maybe i will.

As for booting 64. Ill give it a shot in the morning. I cant be
bothered trying to stay awake now.

Thanks again,

If it is night time where you live then you can't buy from newegg.com so the link is of no use. Where do you live?

The 4400+ 2.31GHz cpu specs you were asking about--the 4400+ is the AMD processor type. The 2.31 ghz is the speed. Back in the old days, AMD would name their processors by what they thought was the equivalent speed an Intel cpu would need to run at to do the same job. I don't know that they do that anymore but if so they'd be saying their 2.31 ghz cpu runs as good as an Intel cpu at 4.4 ghz.

To see the ram using cpu-z or whatever you may need to make sure you're using a version of that software that's able to see that much ram.

Does the 6 gig show on the posting screen? If not then you've exceeded what the motherboard can handle or there's some other hardware problem. To successfully run that much ram you need the right motherboard and OS. The 64 bit XP will work as long as the motherboard "memory controller supports memory swap functionality": There's some additional info on that here:

Good point. I never thought about that part.
I live in Victoria, Australia.
Anyways, like you said, maybe i should wait for windows 7.
Vista isnt that important except that i just need to test my 'small' programs on it too. make versions for XP and VISTA. you get the idea.

Wow, thanks for that.
That definitely explains the 4400. Its not bad i guess.
As for the CPU-Z. I'm pretty sure it can see that much ram - there is no reason it wouldn't be able to.

I have an S-Serias GIGABYTE motherboard with four ram slots. I couldn't imagine that they would make an extra two slots just for show.
But then again. I just checked its website (this) and it doesn't look too convincing. it says "Dual channel DDR2 Ready.
I know i purchased compatible ram. That's not the problem. But now it is time for a restart. Ill update this post once i've had a look.

Thanks to you both,

Oh... Great... I really AM Genius!
The Slot #1 RAM wasn't inserted properly.
I'm really sorry about that.

I also checked the post screen...
It was prety pointless as my computer loads so fast the screen flashes black for a second and starts loading GRUB.
After 20 or so attempts i finaly managed to read something along the lines of "DDR2 Single Channel" which sure doesn't agree with the "Dual Channel DDRII" Which is written in bold letters above my ram slots.
Or for that matter, the website i posted earlier.

Thanks for your help and i really am sorry for my idiocy.

I told you above that you need to install 1 stick in #1 and i stick in #3 for dual channel.

Your graphics card will interfere with installing in #1.

Hit the Pause key at any time in the POST screens to freeze the screen. Hit space bar to start again (or any key).
