It's kinda funny the difference between these two is about 100Mhash/s which is significant. I've been testing with different core and mem clocks for the first 6990 but still similar results.
INFO:
- Fan speed at 60% for both cards.
- FLAGS: -v -w128 -f1 (poclbm)
- Brand is PowerColor.
- First card uses 750W PSU, second uses 650W PSU.
Any ideas what went wrong? Or is it just the card?
Solution:
Set BIOS switch at "overclocked" position 1
