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.
