Hello, this may seem like a pretty noob question but I am new to computing. Well basically I have a sapphire HD6870 and on the box it says 1GB but when I go into Dxdiag it says "Approx. total memory: 743mb" Also, when I go to can you run it I fail BF3 recommended just because it says I don't have 1gb vram, any help would be greatly appreciated.
if hes running 32bit os. you may have a point. but as far as i know the gfx ram is counted b4 system ram so when the o.s counts to 4 gig it should take 1 from the system memory and leave the gfx memory intact... so you are left with 1 gig vram and 3 system ram. so a grand total of 4 gig.
if your on 64bit then your card has an issue. as it should display your gfx ram and some extra that windows sets aside... mine totals nearly 4 gig of display ram for example and i have a 5870 gig version.
get gpu-z... it should tell you how much gfx ram is there regardless of the o.s.
