My point has not been limited to xp. So when I gave my link, it was simply to show that a 32bit OS, vista with sp1 in this case, can show all the physical memory installed. Quit turning it around into your argument, and quit bringing up xp and lower. You aren't staying on point.

And your second pic doesnt have SP1 installed. So I don't see how it's relevent now.

I read the whole page and understand what it all means. While you went on saying how the video card affects blah blah blah, my point has been how much ram shows up in system properties. Never have I disputed how much is used for jack, only how much is shown to exist.

Try going back and reading my other posts instead of making me retype everything I have already said.

[QUOTE="hercule5"]I understand better now what you were saying, but I fail to see how memory is allocated to devices and subtracted from total system memory but only with >4GB installed. I would imagine it to apply no matter how much memory is installed. Not that I disagree with the facts, but I would imagine you can follow my logic there. I wasn't giving inaccurate information. When the system memory differs with 2 different motherboards, you come to a conclusion, and that is a fact, based on experience. Bebi_vegeta

OK, I am not saying that with different mobos it will always be the same. But there is a chance if you have 2 different mobos, both with 4GB of RAM , they will see the same amount of RAM in a 32-bit OS.

But I can guarantee you, that if you have 2 identical or different motherboard, and one has a 256MB GPU and the other has a 512MB GPU, the one with the 512 will see less of the 4GB, than the one with 256.

Your experiences are not wrong, just incomplete. If you would have read those links you would have read how the mobos do affect, but the differences will be quite minor from one board to the next. While the GPU will depends on the different sizes of VRAM.

The inaccurate information you were giving was that GPU has nothing to do with it, and that our explanations had nothing to do with it. I understand it is sorta confusing. That is why the web is full of people asking where is the rest of their 4GB of RAM.

I've read the Os Vista 32bit with SP1 can see 4Gb... but, I cannort confirme that. But of cours, can't use all of the 4Gb.

"After you install Windows Vista Service Pack 1 (SP1), the memory (RAM) value reported by Windows Vista may increase if the following conditions are true:

* The system BIOS has reserved physical memory for graphics or for other peripherals.

* Your computer has more than 3 GB of system memory installed.

This change occurs because Windows Vista with SP1 reports how much physical memory installed on your computer. All versions of Windows NT-based operating systems before Windows Vista Service SP1 report how much memory available to the operating system. This change in Windows Vista SP1 is a reporting change only."

I believe this proves my point.
