How to keep track of temperatures on an AMD FX 8 core CPU
How to keep track of temperatures on an AMD FX 8 core CPU
I have an FX 8300 and an ASUS 970 Pro gaming/Aura. I need to track the temperatures. HWinfo64 is displaying a benchmark with a prime 95 small FFT, using CPU package, showing the same temps as AIDA64 Extreme Zen which are about 20 degrees higher. AI Suite 3 displays the same values as AIDA64 Extreme Zen and that’s around 61 degrees during prime 95 small FFT. AMD overdrive is intended to reveal temperatures before the CPU hits its thermal limit; if it’s around 29°C, it means it’s close to dropping. The overdrive voltage is set at 1.1875V per core, while CPU-Z reads 1.332V. I’m not sure what tool to use for monitoring my FX 8300—usually I rely on core temperatures from Intel CPUs (though sometimes core temps don’t start up properly). HWinfo64 works well with AI Suite 3, so I thought it was showing accurate readings. Someone suggested only using AMD overdrive, but that showed lower temps than expected. I tried using CPU package in HWinfor64 to display the temps in the taskbar, which matched AMD overdrive. Reddit says combining HWinfo64 and AMD overdrive gives a reading near 71°C, which should align with core temps around 61°C. That would mean if it’s at 71°C, I should be fine at around 4.5GHz, currently I’m at 4.2GHz with a Noctua NH-D15 cooler. The voltage in AMD overdrive is 1.1875V per core, but CPU-Z shows 1.332V—maybe that’s the correct value. It’s puzzling why the voltage seems off. How can I effectively keep an eye on temperatures during benchmarking? I’m really confused and need guidance.
Begin by not taking for granted your ability to reach any specific clock speed. You could encounter a hard stop sooner or later than expected. Just because you're at 4.2ghz doesn't guarantee your CPU won't become unstable at 4.3ghz. If that were the case during overclocking, we would all simply check our minimum voltage settings and use a calculator to determine the CPU's upper limit.
On the other hand, it doesn't mean a 4.5ghz maximum is fixed either. The truth lies in actually trying to push it beyond your current settings!
For temperature tracking, tools like Speedfan, HWmonitor, RealTemp, Speccy are commonly used. There are many others available, but these are some of the most popular options people rely on. I personally prefer Speedfan because it allows me to customize and precisely control its behavior to match my needs.
The limit is set to 4.2 ghz due to the low FFT temperatures from prime 95.
Which Prime 95 version are you employing? Various configurations yield distinct outcomes. Certain setups impose greater strain on the CPU than even video encoding might. Others require less workload compared to AIDA 64.
71C in Prime 95 isn't too bad. Mostly since you won't encounter such high temperatures outside of Prime.
I never get 71c, max you should get is 61 or 62c
aida64 is showing 36c for all core (of course, since theres only one sensor for the cpu temps on a amd fx cpu), ai suite 3 is showing 50c, i have set core temp to that or else it would have ben lower, amd overdrive 34c (34 for before it shots down, thermal threshold)
I can't oc my fx 8300 since i don't knopw the temps and don't want to have red numbers in ai suite 3 which is set to 65c that i do reach at max rpm at 4.3ghz which is a low speed for an amd fx cpu that should be able to reach 4.4 or 4.5ghz and 1.4 volt or higher should not be a problem for an fx cpu unless it makes the temps insanely high

There is no requirement for the CPU to overclock to a specific speed. Whether it can or cannot depends on various factors. If you believe any particular CPU model could achieve a certain clock speed, you should be aware that it might not be offered at that exact figure. The maximum temperature is 70°C as per AMD, and the maximum voltage is 1.5V. Setting the thermal threshold to 34°C seems unusual.
34c? amd overdrive displays temperatures prior to thermal shutdown when it indicates, for example, 34c, then it alerts before reaching high temperatures. My readings with core temperatures are synced in AI Suite 3, but adding the overdrive and HWinfo64 values doesn't total 70-71c.
