Hello, here's my problem. I have a CPU - AMD Ryzen 7 1700X. And my PC can't see 4 cores on it (simply, they have just disappeared). It probably happen after than I disabled the feature in BIOS called "AMD Cool'n'quiet". This is weird, it has to be 8 cores, but after disabling that feature, windows shows only 4 of them. I've asked for help, and they said to check out some kind of "Advanced Mode" in BIOS of my motherboard. So the question is, how can I get to Advanced Mode in BIOS on my motherboard (ASRock X370 Killer SLI)? Because I need to check if maybe there is some kind of feature to lock some cores, but I cannot see it. Or tell me, maybe there's some another issue. By the way, there's a weird situation, because Device Manager sees all 8 cores and its 16 threads, but in AIDA64 and Task Manager it doesn't. Thanks in advance.
PC Configuration:
Windows 10 Pro x64
ASRock X370 Killer SLI

ASUS GeForce GTX 1060 6Gb
Crucial Ballistix 8Gb
