4GB RAM and 2GB GPU RAM on XP
- Thread starter Jiniix
- Start date
I think I have already done that. The address space reserved by the graphics card is usually smaller than the amount of vram (if more than 256 MB).

A 5770 CF set up will reserve 2GB, you know how I know, I had that set up.
Secondly, the moment that GPU set up requires 1GB as in gaming (easily done), your system memory availability will drop to what I say. It has to. Which is the point of the OPs question.

The picture is a bit bigger. A lot of stuff will be assigned address space, not just the graphics card. Then there is alignment and stuff. Then there is where the bios makes the cut between mmio and system ram space / remapping line.
The result of the total equation can be that you have 2 GB left to system ram below the 4 G address line.
To add a bit more about remapping: Depending on the bios, if you have 2.x GB available address space for system ram below 4 G, you will probably end up with only 2 GB, if you enable memory remapping in bios. Just an example.
Edit:
The graphics driver can address whatever vram it needs to by writing to the control registers. The "window" (address space allocated in the cpu's address space) is not fixed to a specific area in the vram. Also, the gpu can easily address all the vram internally. The address space allocated doesn't grow.

M3A32 MVP Deluxe This is the motherboard.
Be my guest to find chipset drivers for this boards, I'd like to know how you can say it's compatible.
With both this and the Wifi-AP board, there are no drivers under Windows 7 x32 and x64 available for download.
I've also manually downloaded SB600 drivers from AMD's webiste as well as tried using DriverGenius (which works flawlessly 9 out of 10 times in my experience)
