Im am pasting this from another tech forum I posted it on. Was told I should it here too. I added a few more things I have noticed.
"So, yes I am an early adopter of the 290x's. I bought 2 of the Sapphire Battlefield 4 editions and have them set up with crossfire. I will list specs first, then explain issue.
HAF 922 Case
Sabertooth Z77 MOBO (With most up to date BIOS possible)
1000 Watt Cooler Master Silent Power Supply
16GB of Trident X Memory at 2400 OC
4.5 GHZ Sandy Bridge Processer (2600k)
Samsung 840 EVO 1 Terabyte Drive
3x 1920x1080 --> For Eyefinity
Windows 7 64 Bit
This is the issue:
My 290x's run like DREAMS On one monitor, non-eyefinity, ZERO issues. Eyefinity on the other hand...
3 Games I have tried. Resident Evil 6, Arkham Origins, and Battlefield 4.
Can I put the system into eyefinity? Yep no issue there, but for some reason, after 5-15 minutes in Eyefinity when i game (not single monitor) IT freezes, randomly, the whole system, can't even turn cap locks on and off on my keyboard type freeze. Everytime except in BF4, about 10-20 seconds after freezing, monitors black out, and say there is no signal. There is nothing I can do except reboot. In BF4, it only froze and just stayed stuck. After forced restart it does boot up, but driver does not run and gives me error saying, Driver is not installed or did not run properly, please install drivers for your card.
This happened in oth 13.11 Beta 6 and 7 Drivers.
If this is a driver issue... that people have experienced in crossfire, I am quite content in dealing with it and playing single monitor until a hopeful fix. I am not a fanboy, and don't care if Nvidia "supposedly" has "OOMGZ BEST DRIVERS EVER"... they don't, they fail too, have had both companies cards at different times, equipment malfunctions, so don't tell me to go Nvidia, they both have issues as companies, run by humans, making products. I am specifically targeting this question more so at people who crossfire and may have experienced this kind of issue before and maybe tips or "It happens" in regards to the issue.
My OC on CPU and RAM have both been tested in Prime95 at 24+ Hours with no errors (yes i know that is not the end all to end all tests) and I don't ever leave my system on except in RARE occasion for that long anyway, so I do not PERSONALLY feel that is the issue.
Thank you for your time"
Now also I have noticed, it does it in non-eyefinity mode, it just may take longer to crop up then eyefinity does. I had a GPU-Z log, that showed the card never read temps over what i had it set at (whether it be 80 or 95) I am currently on the Beta 8 Drivers, and has done it on 6,7 or 8 beta drivers.
I hope it is just a driver issue and not faulty card =X, I feel like it is a driver, because the audio also will keep playing in the game, but the whole computer just freezes, and does not unfreeze unless i hard reset it.
