This is because the addresses have been allocated differently at set up.
Although it is possible to change the allocation, I really wouldn't
recommend it because unless you really really know what you are doing, you
can end up with a non working system. These addresses are high up the
order, and there will almost certainly be something below it so you are
unlikely to make any difference anyway.

Control Panel should have an nVidia utility. Opening that should give you
screen with a 'Properties' or 'Advanced' button that opens to a screen that
shows the video hardware configuration. This should state the video memory
size and whether it's dedicated or shared (but as it's nVidia graphics,
don't be surprised if it's both).

The difference in the addresses is exactly 512MB that is the available
memory I loose.
I think this is because driver or the like are not loaded in the same
sequence.
I'd wish to change the order of components loading in order to get back my
512MB or about this. Do you know where I can find this sequence of loads?

I didn't find anything more with nVidia utility in Control panel. It is more
a configuration program to change number of pixels, colors, and so on,
nothing about memory (in any tab I could open).

Once again I appreciate the time you spend to help me.

It is not the sequence of loading that determines the memory allocation. It
is how the plug and pray routine allocated the memory when the hardware was
first installed. Once the allocation has been made, it stays fixed unless
something is installed which requires a reallocation (usually something with
a large allocation requirement). Changing the allocation will only release
the address space if there isn't something occupying an address lower than
your graphics card (and even then, it is allocated in blocks). This is most
likeley, because addresses are invariably allocated well below this address.
This is a reflection of the fact that the video adapter is one of the first
things to be installed.

My nVidia control panel has a hardware tab, but it is a newer 8600 family
device so yours may differ.

Is it possible if I find and deinstall something that is allocated higher in
the memory and then reinstall it, it may be possible memory allocated to
video will change and I may get back my 512MB or a little bit less?

I didn't see a "system info" link at the very bottom of nVidia control panel.
It gives me for both:
- ForceWare version : 156.19
- Memory : 512MB (dedicated 256MB)
- Video BIOS version : 60.84.66.00.05
- IRQ : 16
- Bus : PCI Express x16
Then a list of components (DLL) all of the same version (6.14.11.5619)
Do you know what does the "memory" line mean?

Once again your post learned me much.
Michel

Ok, now I see it is not possible. I dumped the allocated memory (with the
help of AIDA32, ancestor of Everest that Paul talked about).
It is about the same (a couple of things that switched) but I have one more
line:
Memory C0000000-DFFFFFFF Shared Bus PCI
that kills the 512MB.
I don't know what it is for but I'm pretty sure I can't do anything about it.

Thanks for your valuable help.

I forgot to precise:
E0000000 = 3584MB
C0000000 = 3072MB
Exactly the figures that give task managers and so on.

Thanks, but I got the conversion without the subtitles.

I had no doubt you'd got it, it was for future readers.

Ah! You mean the hard of thinking.
