    I have installed my new ATI radeon on my mac pro 1,1 2006, and when i turn the mac on it comes a black screen and then a white screen for a second, and black again! I have tested the card on one of my friend's pc's, and it worked perfect! put on my mac it doesn't work. I have also two 6-pin power connectors that works fine. can anyone help me? Sorry for my horrible english :), here is my specs

    Prossecor: 2 x 2,66 GHz Dual-Core Intel Xeon

    Ram: 4 GB 667 MHz DDR2 FB-DIMM

    System software: OS X 10.8.4

    Why not take a moment and tell us about the important part, the 5870?

    Which model and what connectors and how are you connecting to display?

    VGA to HDMI? Do you mean DVI to HDMI? Why don't you just use HDMI cable?
