    Optimizing 4K with quadfire configuration


      I am wondering if there is any optimization I could perform with my AMD setup tht would take advantage of using crossfired 295x2's? I am playing Blade and Soul and not seeing any performance increase from using two of these cards. I am playing at 3200x1800@60Hz with 4K 28" UD590 Samsung monitor.



      Windows 10

      RAMPAGE V EXTREME 2011v3 x99 motherboard

      i7 5820K CPU

      16GB DDR3 2433MHz RAM

      476GB OS/Game drive

      Two Radeon R9 295x2's

              hey there. I'm not sure about quad fire as I'm running 1 single 295x2 mITX build. I do have a question for you since you seem to have 60hz running 4k.

              I have the XFX 295x2 I have a m43-c1 4k hdmi2.0 43" Monitor setup. Before the crimson driver release. the original CCC I was able to select 60hz in CCC

              and in desktop properties. Now using crimson edition 15.12 I have all these new options but I cannot select 60hz in crimson or in game CODBO3 If I turn off

              Vertical sync I can see my frames go up to 60 fps with frame cap on but I have tons of tearing.... What do I need to get true 60hz back on my monitor?

              I'm running win1064bit. Cable matters mdp to hdmi to hdmi 2.0 port 5 on my monitor... Should I just go back to the older CCC? Any help would be awesome!

              You have a spicy CPU, so that will cope with and draw calls fine. I think your hitting the point where that much HP will only really help with benchmarks and possibly 5 years time games.


              Im sure you know but games are written for mortals, so 1 powerful GPU and a CPU of the desktop nature. They run on APIs that cant really do much more in terms of DX11.

              So unless you get a 144hz monitor, @60hz 1 card will do for now. Unless your benchmarking, doing some Blender render or want to be future proof (dispite DX12/Vulkan low overhead APIs kicking off next year) you wont get much more out of them.


              I would kick that Memory Clock up, that should increase the bandwidth a fair bit. Or better, wait for Fury x2 and sell both of your current ones. That will be bandwidth beyond what you could ever need with 2 very fast (like yours now) chips. Your CPU is fine obviously, but though you have effectively 4 GPUs, its everything else related that won't benefit from it.

                alot of games aren't coded for cf , normally afr friendly and 1:1 optimization off will kick them in , but depends on the games , alot of the time mods will actually help get cf working if the online server doesn't kick you for using a mod that is , I also run two 295x2 and can normally force them to work when needed , but there will always be some games that coding will not allow this to work well and that is where freesnyc comes in
