I had a graphics card that wouldn't render properly. I think part of the memory was corrupt, there were 'lines and boxes' across the screen; it was a Radeon HD5770.

The new purchase, an AMD Radeon HD6770 is not getting quite enough frame rates to satisfy at the moment. Since both are cross-compatible with Crossfire if I gather correctly, I'm wondering if I can connect the two, and output through the 'healthy' card.

  • Will this have a decent chance of working at all?

  • Can I damage the 'good' card by connecting one with corrupt memory?

  • This sounds like more of a driver problem considering the HD6770 is several magnitudes better then the 5770. You gain very little from putting the cards in Crossfire given the significant performance differences. – Ramhound Apr 3 '14 at 18:20
  • @Ramhound according to this game-debate.com/news/… page it should work... – LearningUNIX Apr 3 '14 at 18:22
  • I never said it didn't. I just said you would gain very little performace increases by doing so. I also said your current performance problems are a driver issue. I personally would not use the 5770 if you suspect it has already failed. – Ramhound Apr 3 '14 at 18:26
  • @Ramhound thank you for the input, figured both had the same amount of RAM so it might give a boost :/ ... – LearningUNIX Apr 3 '14 at 18:38
