CPU reach 90°C when you use it or on idle mode without doing nothing ?
You should stay around 40°C on idle mode with CPU usage around 2%
If you use heavily the CPU, with CPU usage greater than 80%, you can reach 90°C and go up to 95°C if no OC active.
nope, full load using prime95 / cinebench15
and then my whole system restart randomly
my idle 50~65 with some spikes
and I just use stock bios settings
when using prime95 core stay at 3.78
but its gonna maximum 3.97
help me my whole system restart randomly idk why
check for the latest bios update from motherboards manufacturer
be sure to disable all CPU OC on bios
enable A-XMP and manually select DRAM speed
install AMD chipset drivers 2.04 from AMD website
after, select on Power Plans, AMD balanced power plan
on idle mode temperature should stay around 40°C
if not, check if CPU Cooler is well pressed on CPU die, check thermal past, not too much and not too low, check CPU fan speed.
You can also monitor CPU with Ryzen Master found on AMD website
lowering ram speed to 2133MHz and change CPU fan profile to up speed more quickly and retry.
Usually you can stay at 90-95°C with stock CPU cooler, if CPU up too hot, frequencies should be down.
When prime95 is running what is EDC and TDC on Ryzen Master ?
Otherwise, I'm not sure, VRM on B450 aorus pro wifi are too weak to sustain power drain for long time, prime95 it's a heavy burner. I will try to look for this tomorrow.
I found trick to decrease my cpu temp dk if it dangerous or not
Set core ratio 4.2
Disable core performance boost
Add 0.135 in vcore
I test it now its working crazy less heat and good performance
