Memory not showed in my computer

Specs: Windows XP, 384

I've been thinking of adding more RAM to my computer. I know nothing about computers, so I found This website scans your computer and basically tells you what type of memory you need. I ran their scan on my computer and found some things that I've never knew about.

For example my computer is supposed to have 512 MB of RAM. I checked and I found out that I only have 384 MB here is my proof

But the website says proof that I have 512 MB of RAM. So, what's going on?

I would guess that you computer has a built in video card. The difference between 512 and 384 is 128. Just about the right amount to be taken up by the video.

You do indeed have 512 Mbs of RAM but 128 Mbs is taken up by the on-board video. If you want to recover this 128 Mbs you could install a PCI/AGP video card with its own on-board RAM. However, if this computer is a laptop that option may not be possible.

Hello Stuart,

Fortunately, it's not a laptop. Although, I really have no intent on fixing this, unless I need to. The reason that I want to add more memory is to have Windows Vista as my OS. So, my question now is, the memory that is recommending, is it trustable? Also, will adding more memory make Vista work on my computer?

And yes, you were right. I went to HP and looked up for my product specifications and found out the same thing that you told me about the video graphics thing.

If someone could answer those last questions, I would appreaciate it, or do i need to make another thread?

Thanks in advance.

Why do you want to run Vista? It's arguably the worst OS to come out of Redmond since the much maligned Windows Millennium.

You're gonna need 2GB memory for Vista to run well, plus you should have a *real* video card, not weak onboard graphics. Crucial is a credible site, but you don't necessarily have to buy your RAM from there. If for instance they recommend DDR400 (PC3200), see if you can find a better price at on online retailer such as or

How about listing the complete specs for your PC or at least the model number?

Well if Vista is really that bad, then I'll stick to XP.

AMD Athlon(tm) 64 Processor
2.19 GHz, 512 MB of RAM

is that what you're asking for jam?

Not enough info. Make/model of motherboard? Is the RAM DDR400, DDR2-800 or something else? Probabaly would have been easier to post the model number of your HP.

Is there something that WinXP can't do as your reason for upgrading to Vista? As was stated Vista has not been a popular OS.

Even if it were why would you want to spend cash on Vista and on additional RAM, plus a graphics card.

Do the math, it doesn't make economic sense.

The main advantage of buying HP, Dell, Etc. is that you get a basically free operating system.

If you absolutely must have Vista just buy a newer computer.

Windows 7 (new, improved Vista) should be out within the year. Early reports are favorable.
