Optiplex 990 with dual AMD Radeon HD 6350 video cards

This question has suggested answer(s)

I have an Optiplex 990 with dual AMD Radeon HD 6350 video cards, I have disabled crossfire in the Catalyst Control Center. I have two monitors working on the

first card and they both work fine. The problem is when I attach a monitor the the second video card the other monitors go blank and I have no video at all.

Any help would be greatly appreciated.

    I was having an issue like yours, after going through the whole system with a fine tooth comb. I have come to the conclusion that it all stems from the power supply in the 980 We used a power supply with a max of 305 watts for some reason this is not the case with the 990 it only has 265 max the system if you get two video cards working is completely maxed I would be interested in seeing the spec of the system you ordered so I may help you further with your issue..

  • If you need more than 2 monitors I suggest a single card that supports 4 monitors.
