Question regarding RAM
Hi, I have an HP DV9894ca laptop that had windows vista 64 bit from factory. the laptop has 4gb of ram. I ended up downgrading to windows xp media center 2005 32 bit and in the computer specs it only showed up as 3gb of ram, even tho i have 4gb. So i did some research and found out 32 bit windows xp doesnt support 4 gb.

NOW, i have just recently upgraded to windows 7 ultimate 32 bit, and it is still only showing 3gb of ram, and from what i understand windows 7 32bit should be capable of 4 gb?

does anyone know how to get my computer to show all 4gb of ram in "my computer - properties"?

any help greatly appreciated

Just wondering if maybe your video card shares the RAM and would cause it to show less? What does it show in the BIOS?

No 32-bit OS can use 4 GB's. The amount you see is correct. If you update Vista to SP1, it will show 4 GB's, but still not use it.

Agreed with Elvandil. 32-bit operating systems can't use 4GB RAM. It will see (and use) about 3.25GB. If you are using a 32-bit system, you are basically wasting close to 768MB of RAM.
All parts should go together without forcing. You must remember that the parts you are reassembling were disassembled by you. Therefore, if you cant get them together again, there must be a reason. By all means, do not use a hammer. IBM Manual, 1925
