My Windows XP Pro SP3 only sees 2.75GB out of the 4GB available4. I expected it to see about 3.5GB, but was unpleasantly suprised. I searched online and understand how memory there is a limitation in address space.
Here are a few things about the system:
- motherboard is nForce 590 SLI
- configured with 2x Geforce 7600GS in a triple monitor setup with SLI disabled and both cards in use
- Running Windows XP Pro SP3, 32bit
- System only sees 2.75GB RAM of 4GB physically available and detectable by motherboard. I expected 3.5GB deted.
- there is no integrated video chip/card that is using part of that memory
I suspect that the SLI'ed graphics card need some addressing space and thus the amount of memory available is reduced.
1. Anyone know why Windows only detects 2.75GB instead of 3.5GB of RAM?
2. How I can reclaim the missing 0.75GB of RAM, if possible?
Help is appreciated.
