Why does Cyberpunk 2077 take 15 seconds to load on AK500?

I was annoyed by 15-second loads in Cyberpunk 2077. I tried 3600MHz memory, but it crashed with a BSOD. Using GamePP Memory Controller Monitor, I set frequency to 3466MHz and timings to 16-19-19-38. CrystalDiskMark shows load time reduced to 10 seconds. AIDA64 confirms stability. The config is backed up.
