ATI HD 4650 VRAM detection issue...

user · October 11, 2009, 8:45am

I’ve just installed openSuSe, and after a hard work I could get my ATI HD4650 (1GB, DDR2, AGP) card to work, BUT(!): In the Ati Control Center it detects that my card has only 128MB VRAM (WTF?)
Is this a bug of the ATI driver, or is there any special setting that must be set to detect the correct VRAM size?
Does this mean, that it would/could use only 128MB of VRAM?? :?

I’ve executed the ‘lspci -vv’ command, to list, how much is the mappable memory (for Ati):

...

According to this log, the available memory is only 256MB…But that’s only the quarter of the 1GB>:(

Could somebody tell me: is this only a bug, or the available memory is really just 256MB (128MB according to ATI CCC)???

Or is there any solution to fix this issue???

Thx,

EDIT: Just an addendum:

A part of the Xorg.0.log:

...

...

So after this, I’m totally confused…

Could some linux/tech enthusiast clear the things out?

(the blue texts r the most confusing to me)
