About three months ago I ordered a second Radeon HD 7770 to stick in my build for use in a CrossfireX setup. The card I ordered was an MSI R7770 2PMD1G5, which is the exact model of the Radeon Card I already own. After about 3 weeks of waiting, I finally received the package, but was surprised to see that the card that came to my doorstep was a Powercolor HD7770, which obviously was not the card that I ordered. Although this really caught my attention, I decided, having been waiting three weeks, to open the box up anyways and tried out the card in my system. After installing it on my motherboard, I was surprised to find out that the card lacked a connector for a Crossfire Bridge, while my MSI card did have one. I got a little confused but decided to boot up the system anyways to see if the setup would be recognized as crossfire, which it was. Ever since I've installed my crossfire setup, and especially recently, I have been encountering countless blue screens from windows telling me my graphics display drivers were failing to refresh, or something along those lines. I have tried to re-install multiple different versions of catalyst multiple different times, resulting with little to no success. Is it possible that the lack of a crossfire bridge connector on one of my cards is causing these problems, or is there something else that may be causing the problem? Also, would the difference in my cards that I mentioned above cause any lack of performance compared to if I had two MSI cards running with a Crossfire Bridge, and if so, do you guys think it would be a possibility that I can return my Powercolor card and get the MSI card I actually ordered in return, or is it too late for that? Any help is much appreciated.
