7970 OC CF low windows index??

Hey guys,
I just recently purchased two Sapphire 7970 OC with DualX coolers. Running them in CrossFire. However I noticed that after refreshing my windows index, where I had a graphical score of 7.1 with dual HD 5870's OC'd, the score had dropped down to 6.8.

I know the windows index isn't really important, but why would it be a lower number than it was with the 5870's? I know both cards are working correctly, I tested them both single before doing the crossfire to make sure they weren't bad.

Is anyone else getting the same problem?

16gb G.Skill Ripjaws X (1866)
OCZ Agility 3 120 x2 Raid0 (primary)
3x WD Caviar Black 2Tb (non-raid storage)
Tuniq Tower 120 Extreme Cooler
SeaSonic Platinum 1000

  1. Did you manually overclock them further?
  2. And i am sure you have but did you re-run the assesment and made sure it wasnt just a glitch?
  3. honestly why some people really care about WEI?

    Because it's a fine indicator of general component performance. It can certainly be wrong, but so can other common benchmarks (think Passmark GPU charts). If it drops, it's worth looking into even if it turns out to be nothing. It may be something like GPU throttling because of an OC too high or reduced memory bandwidth due to errors caused by a high memory OC.
  5. i know that but OP mention that both card working properly. instead of WEI maybe he should do synthetic benchmark like 3dmark and look at the score and for the best result he should play games. AFAIK there is no clear meaning to WEI score other than higher number means you have better performing part. just my opinion though
  6. My HD 7850 gives the max possible score 7.9
  7. I'll re-run the index when I get home (at work) and I have ran the vantage 64 benchmark..scored great as well as ingame (average over 100fps on Ultra BF3, at least davamand peak where I logged in for a few mins). So I know the cards are working correctly, I was just blown away by how much the Win7 index score sucked. I have 7.9's all the way except for graphics / gaming.

    What happens if you turn off CrossFire before running the WEI test?
  9. So I gave it a shot last night with Crossfire disabled..didn't seem to help. still only scoring 6.8. I decided to push it a bit more and try more BF3, watched GPUz monitoring in another display while playing..the cards both work amazingly and when overclocked can average 130fps with max hitting 212 (metro with no players in area) and minimum 92 (at bottom of stairs in metro 64player) all settings maxed.

    So I guess I'll just let this be chalked up to a poor know, since it's an AMD based card :)

    Thanks for all your help guys.
