I upgraded my 32 bit system from 2 to 4 Gigs of RAM and Vista recognizes 3.25 Gigs.

Yes and no

Yes and no, but this topic has been covered literally thousands of times, so a couple of minutes of quality time with google should get you more information on the topic than you could ever want.

But as this is well discussed can you tell us what you didn't find out from prior discussions?

I searched from the web but I found nothing useful

In reply to: Sure.

At least, in my case.

Many articles suggest use bcdedit command in Vista 32 bit system, such as "bcdedit /set pae forceenable" but seems to be no use. I think there may be some critical parameters needed to be used.

Sorry but they should reveal the truth.

That it can but most systems report less than that due to video and bios needing to be in the 4GB space.

Your question was answered but I think that was not your true question. If you want to re-phrase that's OK but will you be able to get your PC to report 4.0GB "usable"? No.

The system information reports 4G of RAM
by Magic-wand / April 29, 2013 2:50 PM PDT

But actually, about 3G of RAM could be used.

I posted this question because my Vista 32bit system comes with HP dc7800 could actually utilized 4G of RAM but my friend's could not.

I just wanted to know why.

By now you've learned about PAE and more. All this nonsense vanishes as you move to a 64 bit OS.

But I don't see where you write about the 2GB App limit. Why?
