Radeon HD5850 shared VRam

post #1 of 6
Thread Starter 
So, i recently got a 5850 to my rig and i pretty much love every second with it.
The only problem is that Windows is "telling" me that it currently shares about 1791Mb of RAM to the video card. Giving it about 1815Mb of shared VRAM which i dont need at all. Is there any way to prevent this? The 1024Mb are enough for what i play and i could use the extra RAM to run a gazillion tabs in Firefox which chews on memory like candy.

That's the way Windows 7 managed the VRAM, Physical RAM and System RAM. The more VRAM you have in the system, the more shared will be allocated by Windows. So far, there's no way to change that.

 

For that reason, some users who have a lot of VRAM such as 8-12GB of VRAM will have 24GB of system RAM installed.

That is just absurd.. There should be atleast an option to select how much vram we wanted.
Thanks anyway. =)

That's allocated, but it doesn't mean system can't use it. This is mostly for games failing due to ram requirement, it slows down but doesn't reset/lock the system. As I said, it will shrink if GFX card not using it and system needs it.

Sounds pretty sensible to me .. why have loads of RAM sitting there doing nothing when it could be doing something!

Of course It would be a good idea that , if you did open a gazillion tabs in Firefox , then that RAM would be re-allocated somehow!

Lets hope so anyway ...
