    R9 380x Crossfire Issue

    millyster

      Hello,

       

      I was wondering if there's anyone that can help me with this. I recently got another Gigabyte R9 380x and was excited to run crossfire on games like BF1 and CS GO. As soon as I set it up and started to run BF1, I noticed the loading screen is laggy and the sound flickers. Moving on to the game-play itself, it feels like disabling crossfire provides much smoother game-play and more FPS. The game is unplayable with crossfire enabled.I was hugely disappointed with the performance.I then tried CS GO, and its the same exact story. With crossfire enabled, my FPS drops and the game looks a lot worse than when crossfire is disabled. I run at a higher FPS and the game is much smoother with only one card enabled.

       

      When I try to run BF1 with MSI Afterburner on, the game crashes and this error is displayed. 

       

      I included two short clips of BF1 game-play with and without crossfire enabled. Here's crossfire enabled, and here's crossfire disabled.

       

      Can anyone help me out with this? I noticed when I turn on DX12 on BF1, it gets better with crossfire on but still, the performance is not as expected, I'm better off with one card than two. There surely is something wrong, I just can't figure out what. I tried swapping the cards around in the PCI-e slots, checking the PSU connectors, reinstalling drivers over and over again. Nothing seems to work.

       

       

      Here's my specs:

      GPU: 2x Gigabyte Radeon R9 380x 4GB

      GPU Driver: Crimson ReLive 17.4.1

      PSU: Thermaltake Toughpower Grand RGB 850W Smart Zero Fan SLI/CrossFire Ready

          Crossfire is over rated and I wouldn't run a multi gpu setup again myself. Having said that I'd have to recommend turning on frame pacing in amd radeon settings and v sync on the application. See if that helps. Sometimes, the multi gpu setup is firing out so many fps it causes tearing and stuttering because your monitor can't keep up.

           

          Oh and one more thing. The crossfire setup will create a lot of heat and gpu will throttle, slow down, once it gets too hot. This can cause the device removed error. Your gpu throttled so much windows reads it as removed. Please install MSI afterburner and set custom fan curve to keep the temperatures down.
