Not all the video card memory is detected

[Gianfrix]

Hi! I noticed in the Catalyst Control Center that not all the memory is detected by the ATI drivers... I have an ATI Radeon 9550 with 256MB of RAM, while the CCC says that I have 128MB!!

The only distro which detects all the memory is Sabayon Linux.... why?

I use Arch Linux and my MoBo is an ASUS P4R800-V Deluxe...

Can you tell us which version of the driver you are using, and how much system memory you have ( this later one can affect your system if you have 3 or more gb of memory on a 32 bit kernel. ).

Can you tell us which version of the driver you are using, and how much system memory you have ( this later one can affect your system if you have 3 or more gb of memory on a 32 bit kernel. ).

I'm using the 32bit version of the driver on Arch Linux (kernel 2.6.25 32bit) and I have 512 MB of RAM

[Dandel]

can you please now state which driver revision your using... this is easily figured out, just use this command:

dmesg | grep fglrx

one only needs the line stating the version... this should provide some details on what to do next... you might not be running a more recent version of the driver.

I'm using Catalyst 8.5, but this problem occurs with every version of the driver, infact "dmesg | grep fglrx" says:

[fglrx] module loaded - fglrx 8.49.7 [May 12 2008] with 1 minors

However I saw some "interesting" lines... here's the complete output:

No one can help me?

Now I'm using Catalyst 8.6, but the problem is here...

Here's the updated "dmesg | grep fglrx"

I had it the other way around. X detected 256MB of ram on my x1950pro and AMDCCCLE detected the full 512MB. Maybe Bridgman or someone else will be able to get you an answer.

[Kano]

I guess the extra 256 mb are something like Turbo Cache via PCI-E.

There's a xorg.conf option for fglr that lets you force the RAM size. BTW im using the same distro and have had this problem for a long time both on a X1800 and a 3870

I guess the extra 256 mb are something like Turbo Cache via PCI-E.

Nope not true for either of my cards. I think this is a known problem actually

I don't know the status of the CCCLE memory display issue - the only wierd thing is that all of the screenshots I have seen with wrong display memory mentioned were in Italian so wondering if it might be a translation issue. Gianfrix, which language is your system using ?

The AGP error messages in Gianfrix's log also look a bit suspicious.
