RAM not detected

So, thought of upgrading my PC a lil bit. Originally I had only 1G RAM, so i bought 2G more...
I put the RAM in the slot such that 1st slot contains 1G RAM and the 2nd slot contains 2G RAM, but as it turns out, my PC only recognizes one RAM at a time. My Computer properties shows RAM = 2G. So i tried a couple of things...

I emptied both the slots
1. I inserted 1G RAM in slot 1....My Computer properties shows RAM = 1G. (slot 2 empty)
2. I inserted 1G RAM in slot 2....My Computer properties shows RAM = 1G. (slot 1 empty)
Then I took out the 1G RAM
3. I inserted 2G RAM in slot 1....My Computer properties shows RAM = 2G. (slot 2 empty)
4. I inserted 2G RAM in slot 2....My Computer properties shows RAM = 2G. (slot 1 empty)

5.Now I put both the RAMs..1G RAM in slot 1 and 2G RAM in slot 2...My Computer properties shows RAM = 2G.
6.Again I put both the RAMs..1G RAM in slot 2 and 2G RAM in slot 1...My Computer properties shows RAM = 2G.

BIOS wont recognize both RAMs together either...What is the problem then??

but there is this tiny utility: CPU-Z...that shows info about the PC. It recognizes the RAM in both the slots...

I am attaching some screen shots....please tell me what is actually the problem?? Why isn't it showing RAM = 3G??

I have Windows XP Professional sp3

Still need the make and model of your mother board. It may support single channel and the ram you put in may be dual channel, thus is a possible reason why it is only seeing 2gb (1gb and 1/2 2gb stick)

But no one can confirm that without make and model of your motherboard and the new ram you put in.

That's not quite what I meant. Motherboards have limits on the total amount of RAM it can hold.

...does this help?


Errm... I'm having trouble getting specifics on this board..Could you tell me the Make and Model of your computer? (Like is it a dell or HP etc...and the model number)

Hello sagar13...

From your board's spec sheet at HP: Specifications

* Single-channel memory architecture
* 2 x 240-pin DIMM sockets support unbuffered non-ECC 400/533 MHZ DDR2 memory modules
* Maximum HP/Compaq approved memory is 2 GB

well chek this link: (check out the Note under "Installing memory" heading")

It says i can upgrade RAM upto 3.3G...thats y i bought a 2 Gig RAM, i checked this page before buying it!!

http://h10025.www1.h...product=1845591

Scroll down the link above and u'll see that my PC would support max 8 Gigs for 64 bit windows.

I'm afraid that they are not talking specifically about your PC, but only about the different editions of Vista and the amounts of RAM each can support. And that assumes that the motherboard used can support it.

It says i can upgrade RAM upto 3.3G.


Actually, they are only informing you that all 32-bit OS's and 32-bit hardware can only see 3.3 Gigs of RAM....

So technically yes, your operating system can support 3.3 Gigs of RAM. Unfortunately, your motherboard doesn't.

Here is the LINK to the motherboards manufacturer. You'll notice that they state a 2 Gig maximum...

I did some researching, and there are people who are running Win7 fine with only 2 Gigs. However, some also had Dual-Core processors. I'm not sure how it would work with your Pentium 4. After reading a bit more I think you should be able to run it, just don't expect to set any speed records..

So paraphrased,

I'm not 100% on how Win7 would run, maybe, maybe not...Google is your friend.

If you wanted to increase the amount of RAM you can hold, then you would need a new motherboard. Personally, I would upgrade the processor to a dual core...

Windows 7 works fine on 2Gg of memory. You don't need to feed it obscene amounts of memory like you (sometimes ) had to do with Vista.
Please remember that Windows 7 is effectively Vista Mark II and a lot better to boot.
It is possible to run Windows 7 on as low memory as 128Mb. Yeah it'll take all day to do anything but it'd run.

To add extra memory capacity to your machine you'd need to replace the board. You may also want to consider replacing the processor too.
