No Thermal Shutdown FX 8350 ( HPC - High Performance Computing? )

post #1 of 2
Thread Starter 
I noticed that my new FX-8350 managed to get to 85c for a few seconds during OC tuning until I stopped the stress test, it did not BSOD or shutdown

My old FX-8350 from 2014 would shutdown at 70-75c when I was OC tuning it

Does anyone have any solid information from a verified source or personal testing that would verify if this is due to a bios setting or if different 8350 chips have different thermal shutdown configurations?

All FX CPUs have identical maximum temperature, however the throttling temperature limit is adjustable by the motherboard.

At default FX CPUs start to throttle when the tCTL (package "temperature") exceeds 70 units.
Many vendors such as ASUS increase this limit automatically from the default. IIRC ASUS sets it to 90 units.

Reaching tCTLMax what ever it is set to does not result in system shutdown. There is a separate feature called THERMTRIP which only activates when the temperature has reached 125°C. The THERMTRIP is not adjustable and reaching it´s limit will shut down the system CPU VRM immediately.

If you are having system shut downs, they are most likely caused by the VRM OTP.
Most VRMs will shut down when their temperature reach 110 - 135°C.
