My Ryzen 1700 machine has been completely disconnected from power for a few days due to construction work in the house.
Booted first time to settings in my sig as it has before when completely disconnected from power, 3.7Ghz and 3466 c15.
Silicon lottery, I had x2 1700's one couldn't even get passed 2933 using same board and ram.
It took months of bios updates to get that to 3200 yet the other was able to do it very early on.
