I have dual graphics cards and want the bottom one to work on start up
I have a Aurora R1 with dual 5670 cards. The crossfire feature doesn't work and I think its because the top card is going out. It runs way less fps in iracing than the bottom card. I can isolate them by disabling one but when I do that the bottom one does not work on start up when Its enabled and top is disabled, having the monitor plugged into the bottom of course. Hope someone can help. Thank you

I thought the top card was always primary. Try with CFx cable removed.
I would test/benchmark each card in top slot with other removed.
Not to dog-out your machine, but 5670 is not a fast card by todays standards for racing sim (that will take all the power you throw at it). Two 5670in CFx is only slightly better.
Good luck.

Check card function under Display Adapters in Device Manager. It should show both cards.
If you are looking under Sound, Video and Game Controllers, you are looking at Ghost Devices.

You can also look under various sub headings in Control Panel\All Control Panel Items\Performance Information and Tools\Advanced Tools, then select View Advanced System Details in System Info.

I think so. I think that's the HDMI Audio (that's handled by the video card).
When in CFx, only one HDMI can handle the sound, so I would think it would be proper to disable the other one. You can have multiple screens, but only one HDMI audio output. No CFx here to test/ observe, but makes sense to me.

I know my cards are out dated. They are first on my list of improvements. Can a physically disconnect the crossfire cable that connects the two. I tried pulling on it a little and it didn't budge. Thanks for your help

Hello guys
I have a question about crossfire
whenever my crossfire is enabled the device manager will always show to high definition audio devices enabled
but one of them is disabled/ not working properly
is this normal?
But when I disable the crossfire then both high definition audio devices are both enabled and working properly
I am confused about this

Yes I do have two of them displayed under display adapter.
Under system device I also have two high definition audio controllers.
When I turn on crossover one of the high definition audio controllers will fail
I don't understand this.

When Crossfire is enabled one card becomes the master controller. Normal.
When disabled they operate independently.

So then it's normal for the one high definition audio controller to be disabled?
While the other one stays enabled in device manager?
If this is true if I hook up a second HDMI cable
.then that second high definition audio controlle. will be enabled
M I understanding that correctly
