My experience with the VIII hero has been pretty good for the most part. Just a warning, when updating the bios it can do some funky stuff and reboot many times on its own. Im not exactly sure what happened because I flashed with no display and it just started doing stuff. It worked though xD.
I gave up trying to get Linux to run as I still have some bugs in windows 7 pro 64 bit that Im still trying to iron out. One thing is my Logitech C920 Webcam is not recognized on boot, I have to replug it for the LWS (webcam software) or windows to see it. Hangouts and skype need the same treatment. My mouse (G600) and keyboard (K95 RGB) are fine.
CUE has one bug, I have to delay startup because it actually starts faster than the USB 3.0 driver so it doesnt see the board. Replugging or restarting CUE is a work around or delay the startup of CUE (winpatrol or task scheduler).
This motherboard's asmedia sata ports are not great. Ive had speed issues with hdd's and ssd's on those ports and had to opt to not use them. Also Samsung Evo 850s are a little weird. Before I diagnosed the asmedia sata driver being a little weak I tried a couple different drives (samsung and sandisk) had to use only the intel controllers. Samsung behaviour was copying files would just hang randomly after a while, hdd led would stay on forcing a hard boot. After I switched it to an intel controller its fine. Since I installed linux and turned off secure boot the samsung drive causes the hdd led to stay on constantly for a minute or two after login then everything is fine. Haven't nailed that down yet.
The network drivers for LAN are wonderful no issue. Audio drivers are crap. I had so many issues with the audio drivers I had to uninstall and use windows generic drivers. Also I would recommend avoiding AI suite (no surprise) as it seems to mess with stuff.
Once I got everything into gaming order. It games well, stable at stock settings and what not. One crash on witcher 3 but i have no idea why. I think a bug created a short -_- we have a ladybug problem in the fall and spring.
Unsolved issues: USB problems, logitech C920 isnt recognized on boot, cant install old usb printer (says bios doesnt support usb install).
If anyone has any questions about the viii hero drop em below and I will try my best to answer questions concerning the cpu or mobo. Sorry for the scatter of text, end of day and wanted to get it all down in html.
