I am having a lot of serious issues here. I'll start by stating the end goal: Running CrossfireX with mantle and playing BF4. Is it even possible? Probably not. lol But I figure I'll ask first before I throw these cards away.
So I usually run a GTX 770 2GB with tuned settings to get 100-120fps at 1440p on BF4. I've been told I can have higher performance with CF 270X's so I'm trying that (already had them from a mining rig). However, as soon as I start up battlefield I got a VRAM/memory allocation error. I heard using "repair game" would fix that, so I did that and it seemed to update something and now I'm not getting that error, however I am getting THIS error now
So that's problem #1
I might have gotten it to run in crossfire with DirectX but it's hard to tell. GPU frame time graph was all over the place so that's a good sign
#2 is: My second card is stuck at PCI-E 1.1 for some stupid reason.
and here we go for #3 MSI Afterburner will not display any VRAM counter at all nor will GPU-Z. Ughhhhh And #4ish GPU Usage monitoring is stuck at 0%.
~~~~~~~~~~~~~~Less important below~~~~~~~~~~~~~~
#5 Every time I enable/disable crossfire or change my refreshrate my QNIX2710 displays crazy lines like I'm trying to set an unsupported resolution. Then I have to unplug and replug my DVI-D cable to get the monitor to work (it will restart to the lines) I think this is because it sets it to 1080p for some STUPID reason which my monitor did accept on my 770 but whatever...
#6 Every time I hit apply on MSI Afterburner the screen glitches and gets some garbage lines for an instant, like the bottom of the screen is pushed down 2 inches by it. Happens on my mining rig too, totally different system and drivers. ***.
~~~~~~~~~~~~~~~~~~~SPECS AND OTHER INFO~~~~~~~~~~~~~~~~
Omega 15.x, MSI Afterburner 4.1.0, ULPS disabled, GPU settings synced. Drivers cleaned with DDU.
Please help, I've been posing around and nobody is responding.
Problems #3 and #4 are solved by removing the Nvidia driver with DDU.
Problems #2 and #5 were solved by using a different Windows installation (very close to new)
