I have an interesting problem that maybe someone here has encountered. I've been running a VIII Gene/6700K/GTX970 build for the last two years without any trouble. Today I upgraded to a 7700K (delidded) and the computer still boots into OS X perfectly fine. I was able to run a Geekbench score:
https://browser.geekbench.com/v4/cpu/4960331. So far, so good.
The problem is that I'm no longer able to get into the BIOS setup. When I press F2 from the boot screen, I get a black screen and it hangs there. It never makes it to the setup screen. The mobo LCD says A9, which is listed as "start of setup" in the manual. If I don't interrupt the boot and let it run, it makes it into Clover and OS X every time. I'm typing this post from the system right now.
I've tried pressing the CLR CMOS button but it didn't do anything. I've pulled out the GPU and tried onboard video, but that didn't help either. I haven't tried flashing the BIOS yet (v. 3504), but honestly, I don't want to try anything too drastic since I'm able to boot right now and I'm afraid of bricking this system. However, I can't claim any of the CPU upgrade goodness until I can get into setup to overclock!
Any ideas?
