  1. What power supply are you using?
  2. What is your power supply?
  3. I dont see why you would ever pay out money for 2 hd 7770's just so you can crossfire them. One good card is always better than 2 "medium" cards. If i ware you i'd buy the r9 270x or the r7 265x. When you crossfire GPU's there will be errors.

    600w aero cool tower
  5. Each card can run up to 150w per card. So 300w total between the 2 cards. That leaves 300w for the rest of your components to use. So it could be a power problem.

    When you say that when you run 1 card it works just fine. When you test with a single card, is it always the same card you run it with? If not, I'd run each card individually with a benchmark program to see if any fail on their own. If that is the case that is your problem.

    To be honest I think it is power problem tho. The fx8350 can run up to 160w on idle, and over 350w under load (like in a game). If you add up just the processor and the 2 cards your at 650+w! I'd upgrade your psu.

    Underpowering your equipment can cause damage. If they aren't toasted now, they will be.
  6. when i convert video using both cards it all works fine, that software use both cards fast as f@*k! cant be power, drivers?
  7. It is your power supply. One it is not really a good quality and i doubt it actually deliver 600W on the 12v rails.
    Second 650W psu or 750W is better.
