Failed attempt at Undervolting AMD Ryzen 7 3800x

[maxmbg]

I recently got an AMD Ryzen 7 3800x for my birthday, paired with an ASUS ROG Strix B450-F Gaming motherboard. I installed the new motherboard and cpu successfully, but when checking the temps I noticed that they were oddly high.

I read somewhere online that with the 3800x, you have to undervolt it and overclock it to take temps down while still not losing too much performance. I attemped to do this, but after the fist try not doing anything, I tried again. The second time I did it, when I tried to boot it the red CPU light on my motherboard was lit. I tried to reset my cmos without any success. I have no idea how to fix this issue and would accept any help. (My max temp when running Cinebench was about 85c)

 

Specs:
CPU: AMD Ryzen 7 3800x
CPU Cooler: AMD Wraith Prism
Motherboard: ASUS ROG Strix B450-F Gaming

Ram: 16gb Corsair Vengeance LPX 3000mhz
GPU: MSI 1660 ti Gaming X

Power Supply: Corsair CX 650M

95c is throttle point. How close to that are you?

When I was testing Cinebench my max temp was about 85c.

You're good. No worries unless your system throttles, then upgrade the cooler. (which you can always do whenever...)

I am idling at 60c, but the problem now is that the system isn't posting.

Clear the cmos to get the system running again.
