I'm using CoreTemp v1.1 (from the screenshots) and have HWiNFO64 as well; they show the same value.

A screenshot of HWinfo64 with the full range of temps and voltages for the CPU and Motherboard would be most helpful. A pic at idle and a pic after 10 min of stress please.

The MSI 970-G43,45,46 motherboards have a very bad reputation. Some have caught on fire while being overclocked. Yours at least appears to have a VRM heat sink which is a big help. Click the link and then select "MSI" for more info.

They were designed before FX came along and are not really suited for it. You are using a 6 core so you have some head room there. Please re-enable Smart Protection and monitor VRM temperatures. An infrared thermometer is best but just touching the heat sink is ok. If it burns your finger, then it is too hot. Here is a pic of an IR thermometer in action on the back side of the VRMs while the system is idling. In action they can go over 80C.

I've got the temps and voltages; but those are at the stock frequency! I thought that weird Tj. Max thing had something to do with the overclock, but it does not. I've stress tested with Prime95 Blend preset.
Screenshots of the overclock are following! post #16 has the results of the overclocked run

I've also re-enabled the CPU Smart Protection when I tested it with disabled. The heatsinks aren't that hot (I touched it with my finger), but still quiet warm.

[Edit] looked it up and edited my numbers. Thermal limit is about 70'c on most FX chips.

Ok so a cpu temp of 49 measured by HWinfo64 is usually the inverse of the thermal margin. If you looked at the thermal margin in say AMD Overdrive it would read about 21'C under full load. Take the Thermal limit of 70'C (i forget the exact value off hand) then subtract thermal margin of 21'C under that load...boom you should get your 49'C measurement from HWinfo64. This pattern holds true at lower temps too, which is often why lower temps look weird. Sometimes below room temp even which seems impossible. Its due to how thermal margin losses accuracy the further you get from its thermal trip temp.

Neat thing is if you know this and you know the limit you always know how far you are away from your max temp using either tool.

Limit - Thermal margin = Approximate current temp


Limit - current temp = Approximate thermal margin before shut down.

[Edit] The temp that would worry me the most is your Auxilary temp at 73'C under full load. Anything abive 60' is likely to cause instability in the long term and maybe even board failure.

You may want to look at active cooling on socket and VRM areas.

And here are the temps and voltages of the overclocked run. Note that I raised the VCore in the BIOS to have a stable stress test with Prime95 (Blend preset) to 1.298 Volts.

I can't imagine that my cooler (Scythe Katana 4) is capable of keeping the CPU temp that low, considering it is pretty tiny compared to other air cooling solutions. It is also important to say that the value of Tj. Max is at 52°C. So the measured temp is lower than that and never or barely reaches it.

I can tell you are still running with multiple power states enabled. That is usually a no no when testing overclocks. I would be willing to bet there are several things you still need to adjust in your bios to help stabalize and limit instability issues. Some can be renabled later but most should not when overclocking. A picture or two or three of your bios settings would help us sort out any settings you may need to change for a better chance of success.

Ps that Auxillary temp hit almost 80'C on your last pic. Thats hot bro. Something to monitor.

So, after another run putting it on sleep mode and waking it up again, Tj. Max went to 80°C and those are the results of the the stress test (10 minutes with Prime95, Blend preset): Temps and Voltages on Load (Click to show)



I've also got some BIOS screenshots: BIOS/UEFI (Click to show)




Maybe I should go with an active cooling solution to lower the Auxiliary temp.

Disable SVM and enable HPC. Everything else looks good.

So a few things to remember when OCing is active cooling on the motherboard almost becomes more inportant than on the CPU itself. Many times the first thing to reach thermal limits and cause throttling or instability are parts of the motherboard, even when there is plenty of headroom on the CPU to go higher.

Ive done case mods to add active fan cooling to the back of the socket area and VRMs as well as fans that blow directly on those heatsinks on the top side of the board. It all helps some.

That being said anytime you see temps approching 70c or higher you need to be careful. Some components can handle those temps better than others and some cannot.

Id do some monitoring of idle temps and temps under normal use and gaming as well. If you only see super high temps while benching with extream stress tests like prime 95 then id be leary of pushing those tests for too long. It has the resl potential to damage on otherwise stable set up during normal use assuming temps are much better there. Constant stressitnat high temps will degrade the life and longegity of many parts andnonce one goes its gone for good usually.

Still useful and important to stress the system beyond normal use for stability assurance, but excessive stressing for more than an hour or a few hours at most is unwise in my opinion. Everyone has their own tolerance for risk though, and their own idea as what constitutes stable.
