I have NVIDIA Quadro NVS 295 graphics card, asus P5B moherboard with 4GB memory, bios 2104, Intel Core 2 Duo E6300.
After inserting NVS 295 graphics, with 256MB, bios sees only 3,5 GB of memory (3584MB), the same issue was with NVS 300.
In bios I am using memory remap option to see whole memory in the OS.
Is there a way to get the memory back?
Explanation about the OS: it is 32bit, but with using PAE it has no problems with accessing more than 4GB of memory, so I do not blame the OS for losing the memory (I had whole 4GB before replacing graphics card to nvidia). I have two computers with exactly the same problem, one with 32bit Windows 7, and one with 32bit CentOS linux.
