Overclocking and using several temperature sensors often give conflicting readings???
Overclocking and using several temperature sensors often give conflicting readings???
I'm trying my first time with overclocking: I'm boosting my 860k on a ga-f2a88x-up4 board using BIOS f7, H100I thermal paste, and a Kryonaut paste. I have R9 290 with Kraken G10 & X31 AIO. There are 2-140 intake fans, one 120 intake fan, and 3 exhaust fans (H100I and X31). My clock is set to 4.5GHz and voltage at 1.4125V in BIOS, but it shows 1.3375V core temp and AMD overdrive. The monitor lists 1.369-1.375. (I don’t get all the differences)
My CPU usage (Task Manager) is 68%, speed is 3.05GHz.
That doesn’t make much sense to me.
It seems only cores 1 and 2 are reaching 4.5GHz, while cores 3 and 4 are maxing out at 1.7GHz.
Now I’m really confused because my temperatures vary a lot:
In HWMonitor: 75-85
AMD overdrive: 37-41
Core temp: 27-32
After 30 minutes of this custom Prime95 test:
Min FFT: 1344
Max FFT: 1344
Running FFTs in place: *check*
My temperatures show
🙁
HWM: 80
Core temp: 31
AMD overdrive: 41.2
Why are all these temps different?
What am I doing wrong?
I can’t figure out how to post pictures otherwise I would.
It relies on the specific measurements being taken, whether socket or core temperatures, and the direction of measurement. AOD indicates the margin against throttling temperatures; a higher value means cooler operation. Temperatures below 10°C suggest potential overheating. Voltages and temperatures change depending on processor workload.
i believe it's stable now. the monitor shows 106 frames per second, which is way too high. according to amd overdrive, my thermal margin is around 13 after about 30 minutes of ibt avx. my cpu temperature (from core temp 1.1) is about 57 degrees. i think i'm good. just need to run a p95 test for about 21 hours.
your thermal margin is fine, but during that overclock when it hits zero or negative numbers the cpu starts throttling. also, i believe 4.6ghz at 1.45 is actually running at a lower voltage than most people use at that frequency, suggesting you have a very solid setup with a good cpu. my 8350 needs 1.48750 volts to run at 4.6 stable, which seems like a bad one from the batch. 🙁 if you haven’t read this guide yet, it’s useful for amd fx cpus
