I have a ATI Sapphire Radeon HD5830, and I successfully installed the AMD control panel on Linux Debian Wheezy.
When I use
lspci -vs 04:00.0 I get this output:
04:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cypress LE [Radeon HD 5800 Series] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Device e177 Flags: bus master, fast devsel, latency 0, IRQ 77 Memory at d0000000 (64-bit, prefetchable) [size=256M] Memory at fbcc0000 (64-bit, non-prefetchable) [size=128K] I/O ports at c000 [size=256] Expansion ROM at fbca0000 [disabled] [size=128K] Capabilities: <access denied> Kernel driver in use: fglrx_pci
As you can see it only gives 256 MB of video RAM. But when I open AMD CCC it says that I have 1024MB memory, which is also the amount of memory the graphic cars is supposed to have.
I also can't use the 1024MB, because when I open Virtual Box I can only give 128 MB to the guest OS.
My xorg.conf looks like this, where I tried to manually set the memory, but that also didn't work:
Section "Device" Identifier "aticonfig-Device-1" Driver "fglrx" VideoRam 1048576 BusID "PCI:4:0:0" Screen 1 EndSection
How do I solve this so I can access all the memory from my Graphics Card?
Any help would be greatly appreciated!
