HD 6870 doesn't really have 1024mb of vRAM like it said so?

post #1 of 7
Thread Starter 
So I was on canirunit.com and it said that under recommended section of Battlefield 3 I cannot run at max because of my limited vRAM. Just to confirm, doesn't the HD 6870 have 1gb of memory? Why does it say otherwise in this pic?:



By the way this was for Crysis to see if it were different...apparently...

Why don't you try a program like MSI aferburner to check your vram and other stuff? what settings are you using on BF3, I'm pretty sure a single 6870 shouldn't be able to run it 100% smooth.

Check under Cpu-z (graphic tab) see what that says

This happens because whatever you're using reads information from dxdiag, and as Microsoft say "The API that DXDiag uses to approximate the system memory was not designed to handle systems in this configuration"

Use GPUZ to check your actual vram - it will report 1024mb.

Ok got GPU-z and says I have 1024mb.

But I still wonder why System Requirements LAb got my GPU memory wrong and everything else accurate.

Go to start menu and type dxdiag and press enter.

Go to Display 1, it will probably give you 740mb.

System Requirements Lab probably read the value from dxdiag.
