Question EDC on 95-100% always and causes PC to crash

Hi, I've had this issue with my CPU that causes my pc to crash when underload. The EDC is always on 95-100% with balenced power mode on, I asked 2 of my friends what their EDC was and theirs are in the range of 20-45% idle and they both have better CPU's than me (I've gotten a Ryzen 5 1600AF and they have gotten Ryzen 5 3600 and Ryzen 9 3950X), I'm not sure if this is the reason why my PC crashes underload or not, but I do think it has something to do with it.
The only way to get I can get it down to 30% is if I have power saving mode on which cuts my clock speed down form 3.2GHz to 1.5GHz, which makes a big performance impact in games.

My specs are:
CPU: AMD Ryzen 5 1600AF
GPU: Nvidia GTX 1050-Ti
SSD: Crucial MX500 500GB
HDD: Seagate Barracuda 1TB
RAM: Crucial Ballistix 3600Mhz 2x8GB
MBD: Asrock B450M Pro4

EDC is the Electrical Design Current limit. It's the limit, in amperes, that the CPU will be allowed to draw on the VRM in peak power demand conditions.

Since that is a percent of the limit I'd have to think it normal to see it above 90% quite frequently when running heavy processing loads. That would be true even if that same processing load would only be light-to-moderate (as idling at desktop) on a more robust CPU.

With PBO settings you can extend the limit, but it will have little or no effect at all on a 1st gen. Running with a manual overclock makes the limit meaningless as it's ignored by the CPU since that takes all control away from the boosting algorithm. In fact, anytime you start making changes to VCore, clocks or PBO parameters the boosting algorithm looses calibration and those indicators become unreliable. That's if they were reliable at all since the motherboard mfr may not have set up BIOS parameters correct for your board and processor combination.
