  • Help with ATI 3870 X2

    Getting real low scores with this video card. Only have one card installed, but it says I have to enable crossfire. 3DMark shows 512MB of ram on the video card, and when I enable the crossfire it knocks it down to 508. Is 3DMark just misreading it, or is there something actually wrong? I've tried 2 different 3870 X2 cards.

    Here are my results, any suggestions?

    ...but it says I have to enable crossfire
    Who or what is it? PerformanceTest certinaly never say anything like this.

    3DMark shows 512MB of ram...
    If you are refering to the product 3DMark 2006, then this is not our product and we can't answer that question.

    The PerformanceTest results you posted don't look so bad to me.

      You score isn't low. Thats about what your looking at with the 3870. My friend who has 2 of them as well scored this:

      3d simple: 2249.1
      3d med: 625.0
      3d complex: 60.7

      3d graphics mark: 939.2

      His system is a amd x4 with 4gb ram, so no bottlenecks there, running vista x64.

      Your score is fine. My 2 880GT's though smack him around 3d wise Should have went nvidia haha j/k
