NEW SKYLAKE BIOSes RELEASED INTEL 0x74 FIX

I would like to report that UEFI 3.20 für ASRock Z170 Extreme4 finally fixed my problem which occured in 2.80 and 2.90.
No more black screen. Booting works, rebooting works, always enetering UEFI works very well now.

I am sorry but I have to disagree, the problems started when access to the UEFI was granted to the OS

But my case looks ver lonely here This is how it behaves: I enter UEFI, Update with Instant Flash. PC reboots -> black screen turn PC off, clear CMOS, reboot PC, at screen for F1 for continue, F2 for UEFI, I enter UEFI, make my settings, save changes and boot -> works turning PC off and on -> works BUT, if I only need to reboot my PC (e.g. updates) -> black screen. Or if I want to enter UEFI AGAIN -> black screen. Than I always need to clear CMOS to get it back work. I also had trouble to downgrade. When I entered UEFI and started Instant Flash, UEFI got frozen. Always! The only way I found was, clearing CMOS again, boot PC, pressing like an idiot F6 for Instant Flash, than question about F1 and F2 was shown, pressed F2 but still pressed F6 like an idiot. Finally the downgrade started. After being on 2.40 everything works normal and fast. I can restart PC, I can enter UEFI whenever I want. No problems. I already resported ASRock Tech support, but the UEFI team is celebrating chinese new year now.

this happened to me too when I enabled the XMP profile on my Ram.

Do you have this behaviour also with everything @ default?

I solved it raising the VCCIO and the VCCSA by 0.05V. Now it's ok even if I reboot. ;)

(but consider that I'm not using the last bios)

Are you sure? The whole mainboard!? But why are lower UEFI version working fine?
And how I work on PC without replacement or I will get simultaneously replacement? And will I get a new "Hardware ID" with a new mainboard and need to reinstall windows? I will go crazy T_T

I will wait for an e-mail from ASRock or stay on 2.40 forever. I got really tired about computer technics from china. It's always somehow broken...
