Talking memory latency new bioses cant get below 63ns no matter what plus the random 1 windows error bug. But ye noticed cache hit...Oh Noes, that is not the bios! You have fallen for the temptation and installed Windows Insider, Ryzen cache is f*ing bugged on the current Insider builds. Just install a official Windows build and cache will be back to normal, WITH the new bios.
Plenty of problems with this developer windows build.
