Please help with this.

*Facepalm*

I need to know which is a more reliable way to measure coretemp, as HW Monitor is reading significantly lower than AMD Overdrive.

I just had to ask, did you core unlock?

My core temps are also lower than CPU socket but as soon as I unlock the core temps shoot up by ~20°C. CPU socket increases by only a few degrees.

use speedfan and/or hwmon. aod is buggy for a lot of people.
go by cpu temps. core temps usually are lower than socket by the way.
are you sure your pump is running at 100% ?

Yeah, and its makes sense that core temps would be higher though, the cooling goes across the heat spreader, meaning in theory the outside would be cooler, but who knows, maybe my mobo just has a defective heat sensor.

But the core temps are having no issues, and if HW Monitor is more stable than AOD, then I will stick with that, I may push an overclock, since prime95 only gets it to 52 C

This is how AMD processors work.

Each core has its own sensor. This is the CORE temp. The cores are just below the heatsink.

The CPU temp is the temperature of the processor on the opposite side of the cores away from the heatsink, facing the socket.

The reason why CPU temps should always be higher is because that side is not connected to any heatsink, the socket area of the motherboard itself absorbs that heat, and since it's not a heatsink it's not very good at dissipating the heat. So the heat generated by the cores will be higher at this end of the processor, where the CPU temp is derived from.

Higher CORE than CPU temps is indicative of a problem with the heatsink whether mounted improperly or thermal paste applied improperly, or a malfunctioning (or empty) liquid cooling system. If it's a thermal paste problem, I'd lean more toward too little rather than too much, since a properly mounted heatsink will squeeze any excess out to the sides. If it's a heatsink problem, and your liquid cooling system is functional, it's not making proper contact with the processor.

Yes, but neither CPU temp nor core temp are in the danger zone, at this point the paste has had time to prime, and everything is running wonderfully. Even if the CPU temp is higher, its nowhere near dangerous.

Also, I just hit 4.1 and 20 MHz. I guess I am now a part of the AMD 4 GHz club

Running a 100% load session of prime95 for about 15 minutes now, and also running some backround things. No slowdown, and idle around 58 C across all cores. I would say that's pretty satisfying. I love ya AMD.

you mean 58c load instead of idle?

Yes, but what I meant by idle, is its only climbing 1C between every few minutes, so its a stable temp idle.


I applied for AMD 4 GHz club, hopefully I get in.
