Default Incorrect Memory Detected on 7300GS

All,

I'm experiencing random lockups on my box and am currently looking into whether it's down to the nvidia drivers.

I've noticed in the Xorg.log the follow line:

Code:
(--) NVIDIA(0): Memory: 524288 kBytes
However, the card only has 128MB on it. Is there a way to force the amount of Video RAM? I've tried the standard X "VideoRAM" setting in the Device section, but seems to be ignored.

Using Gentoo Linux:

Code:
ankh@ted /var/log $ uname -a
Linux ted 2.6.24-gentoo-r3 #2 SMP Tue Mar 18 18:47:39 GMT 2008 i686 Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz GenuineIntel GNU/Linux

ankh@ted /var/log $ emerge -pv nvidia-drivers

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] x11-drivers/nvidia-drivers-169.12  USE="gtk -acpi -custom-cflags (-multilib)" 0 kB
Cheers,

Rich

Default Re: Incorrect Memory Detected on 7300GS

The reported memory value is bogus.
It does not only take into account the real memory on the card, but also any memory the driver has allocated for use as bitmap cache, from system memory.
(normally this feature is only for marketing use, but in case of trying to debug things it is simply annoying)
