Default Re: Video Ram not detected

This continues a thread started about a year ago.

The nvidia driver only detects 32 meg of ram under FreeBSD or Linux although the Windows driver detects all 128 meg.

Looking at the dmesg line for my graphics card, I get:

nvidia0: <GeForce4 MX 440 with AGP8X> mem 0xfd000000-0xfdffffff,0xe0000000-0xe7f

showing that the memory is allocated in two noncontiguous blocks. The nvidia driver only seems to detect the first and not the second (where most of the memory lies).

Actual use of the chip (for games, etc.) implies that only 32 meg of video ram are available to applications.

Suggestions that I tried that didn't correct the problem:

1. Upping the memory declaration in the xorg.conf file.

2. Trying to upgrade the BIOS (my graphics card lists no manufacturer anywhere on the box or instruction leaflet --- even the chips themselves only list the name of their respective manufacturers).
