Posted July 21, 2016 I've got two Radeon 7750s in Crossfire, yet I can't seem to get the setup to work on any Crossfire enabled games. Whilst GPU2 shows utilization, GPU1 always sits at 0%. Opening AMD Radeon Settings shows the GPU, but has "Disabled" in parentheses next to the name. Device Manager shows both GPUs enabled though. I have disabled ULPS. Any ideas?

Posted July 21, 2016 Does your motherboard support Crossfire? **If its showing in the device manager I think it does but I could be wrong, what motherboard are you using?

Posted July 22, 2016 Do 7750s require a Crossfire bridge? If so do you have one on them? Are you running your games fullscreen? Have you tried reinstalling the cards?

Posted July 22, 2016 Have you actually troubleshooted the issue by creating custom profiles, disabling GPU 2 and making sure everything is in order with GPU 1 running at full tilt? Also, I use this as one thing to eliminate with older xfire setups. Don't forget to check if the xfire bridge is dead. Have another one handy.

Have you tried reinstalling the cards? 7750s don't require a crossfire BRIDGE. All games are running in fullscreen, and though I haven't reseated the cards, I believe the problem started with an upgrade to the latest drivers (previously a badge displayed in the upper left corner, though I don't know if utilization was actually occurring on the other GPU.)

The catalyst control panel used to have a universal switch, I thought Crimson did too but haven't used the newest version to know. If anyone asks you never saw me.

AMD Additional Settings no longer includes a universal switch as of the latest drivers. It used to (as well as an option to have a badge in the upper right.)

If you're on Crimsons, you just go to the gaming menu, pick said game, and under "Profile Graphics" there should be a field named "AMD Crossfire Mode" or something. It should have a couple of sub modes. Default, AFR, optimized 1x1, AFR Compatible and Disabled. Bare in mind, occasionally, it used to be the case that Crimson Crossfire settings were not applied to some games, so you may have to confirm with a couple of titles. When disabled, the top 7750 should be running full tilt. The hardware troubleshooting after that is swapping the actual cards around.

Theoretically you could do that as well, but it's pretty brute force. I'd go the soft route first.
