Hello everyone, my sincere apologies for my recent absence! Been a busy guy as of late.
I am going to amend the opening post to include information about this new security update and the web drivers. I had a rough time getting things to work but finally found an easy solution.
Leo, glad you have ironed things out and the build is working for you.
Jimmylet, so long as the memory is compatible with the board you should be good to go, not risky at all to go faster.
Buzo831, stability hasn't been an issue at all for me, its very stable, fast, and fun. I run an LG 34um95, its not quite 4k, but its pretty close at 3440x1440, and my 970 handles it like a dream. I do some gaming and have no problems, even in heavy encounters.
Roguedaemon, Brightness will be controlled on your monitor itself. You may want to go back and find if you installed any of the USB 3.0 driver options in multibeast when you were doing your post installation, there is no need for any of them with this build and it seems to be a major problem when folks install them. If you find you installed any of the USB 3.0 drivers from multibeast delete them and repair permissions. Hopefully that helps with the freezes. As per the low res themes I'm not going to be of much help, I'd suggest finding a fairly recent theme with multiple options in large resolutions and scaling that to your monitor.
