I have 2 MSI R9 390X in my computer. I know both are functioning. However, when I put them both in Crimson will recognize that I have 2 cards installed but will not give me the option to Crossfire. I know where the tab is supposed to be because it showed up once before but when I restarted my computer I no longer had the option.
I have tried an uninstall of the drivers and crimson software, but it still will not give me the option. Am I just overlooking something?
