Been struggling for a while with the cpu underclocking to 1.4ghz under load.
Initially had the problem with stock cooler, so my first thought was - ok, overheating, threw in a good cooler, changed thermopaste, but the problem persisted, so now im thinking - chipset? motherboard?
I have fucked around the bios, updated it, left most of the amd turbo crap off.
Power plan is set to high performance.
AMD overdrive shows Thermal margin -185C after the underclock and 38-40C on idle before the underclock.
After it underclocks, the thermal margin of -185C doesnt change even when keeping it idle for extended periods of time, even though the CPU should cool down, the reading says the temp is super high.
The temperature reading on the CPU is unreal and simply impossible, the thing would be melting under that temp, but with amd temp readings being as inaccurate as they are - the further away from the optimal temp it is, cpu could be overheating, but looks more like a sensor error. As mentioned before with the thermal margin, the temperatures shown here do the exact same thing, once it reaches a certain threshold, the cpu temp shows 206-207C constantly, no matter how long the PC is left to idle.
On idle the cpu temp seems accurate - 32C-35C.
Everything dropping down to abysmal speeds just kills the performance, a restart fixes the issue for a while, until i do something cpu intensive, which means this happens when the cpu/system reaches a certain temperature.
Cleaning out the case helps, so it could be the chipset overheating?
I have ghetto rigged the system fan2 to blow air on the motherboard itself, which helped quite alot, the underclock seemed to stop almost completely, it would kick in only in cpu intensive scenarios, csgo for example. But that doesnt seem to help either now, since i havent cleaned my case in a while, but having to clean the thing every 3 months just to not run into any problems is ridiculous.
Im not sure what to do here. Replacing the cpu/motherboard?
Sensor going retarded makes the most sense here.
I mean, i can see some people saying - Oh yeah, just throw the thing in the garbage can, ohh boy, i want to, but i cant spare the money for a decent intel/ryzen setup. This FX has driven me nuts.
Looking into the motherboard, it seems to be quite shit, it has 3+1 phases supporting a max of 95w and its not heatsinked.
There are so many things that could be failing here, im just not educated enough to see the real problem here. I mean, swapping out the cpu and seeing if the problem persists, and then the motherboard would be the ideal way, but i dont have spare fx processors lying around, same thing for the motherboard.
