Can't enable Eyefinity without crashing in Crimson 16.3

Hello all! Been having some trouble with Crimson drivers lately, which is why I've been using Catalyst 15.11 mostly, and I'm hoping someone here can steer me in the right direction.
First, specs:

Windows 10, most recent build
AMD Crimson 16.3 driver
2x Fury X in CF
i5 4960k @ 4.2
16GB DDR3
1200W

Skip to the next paragraph if you feel you don't need the entire context. So I have three monitors I use to set up Eyefinity for games like Rocket League, of which I typically just run on one gpu. Been having pretty terrible performance with ALL Crimson drivers with most games in general, but for this specific game it was worse. The middle monitor ran at ~60fps but very choppy (unplayably) while the two side monitors would run at 30fps oddly. Turning Vsync on helped a little but the side monitors remained running at 30 (also renders Freesync on all monitors useless). I presumed this was due to AMD's downclocking bug with its Crimson drivers (still think I'm right on that) so I reverted to Catalyst 15.11, which runs fantastic for me except for much newer AAA games. Crimson 16.3 allegedly fixes the downclocking issue; I managed to get this working once and had no problem with Rocket League until I quit the game an hour later.

Problem: After installing Crimson 16.3 and rebooting, whenever I turn Eyefinity across 3 monitors on, my pc freezes at the Windows log in screen after logging in. The monitors lose connection but the pc remains running, and rebooting only delivers the same result every time. Only way to fix it is rebooting in safe mode, using DDU to remove the drivers and then reinstalling them again. I've reinstalled Crimson 16.3 about 20 times or so by now and my most recent try let me actually start and play Rocket League (on the second try, first lead to black screen and I had to blindly navigate the menu out of the game). I don't mind the trial and error, but it's getting tedious and I'm not sure if I'm making progress. As far as I can tell, the problem doesn't lie with: Freesync, Power Efficiency on/off, Crossfire, ULPS on/off, Clockblocker program, MSI Afterburner (although disabling this did get me as far as in game Rocket League, until it crashed when I quit it), or the number of monitors being used.

Has anyone ever encountered this type of problem with Eyefinity before? I don't mind running 15.11 but I have a few games that need the newest drivers so I can't use it forever. Please let me know what other info I need to share and I hope someone can assist me with this. Thanks for your time!

hey first off i dont have 3 monitors but i do run amd radeon.

are u trying to enable eyEnfinity from amd radeon settings? the second tab from bottom right?
check ur radeon additional settings in the AMD EYEFINITY MULTI-DISPLAY and enable/configure.
thats as much as i know. if u already done all that then i just made a fool of myself lol

Lol thanks for the input but I've definitely gone that far :p Appreciate the feedback though!
 


one thing i have noticed with catalyst (not sure about crimson) is when you continue to re install it it eventually works. this was the case for me on some of my computers ~20 installs in

Normally I'd agree with you! But I'm definitely at over 20 tries with this so I'm guessing it's not gonna work this way. I can't tell if it's an AMD driver issue or a Windows 10 issue (there was a patch a little over a week ago that some people are saying isn't agreeing with Crimson).
