FX 8320 hitting 70C on socket
FX 8320 hitting 70C on socket
Hello,
I'm checking my FX 8320 at 4.2ghz and have been following that guide.
I've been running 10 minute tests on Prime95 before increasing the CPU clock by 100mhz.
I'm using the default voltages (1.368v) and have reached 4.2ghz without going higher, but during a 3-hour test on p95, my temperatures are around 74°C in the socket and 58°C in the core after about 30 minutes.
The cooler I'm using is the CM Hyper 212x — are these temperatures normal?
Thanks in advance.

The default settings make it hard to stress test properly because the load line calibration runs on auto, causing the voltage to swing wildly. This leads to CPU clock instability between 3.5 and around 1.7 ghz. The temperatures remain comfortably below 40 due to these fluctuations. You shouldn't rely on P95 for more than 10 minutes on small FFTs—it will overwork your CPU. It's better to avoid this kind of stress testing unless you're doing factory evaluations. There are improved tools available, like AIDA64 and Realbench, which offer better sub-system and real-world testing capabilities. If voltage droop occurs under load, setting the LLC to high might help, but don't push it too far.
The temperatures are far from normal; the safe maximum for that CPU is 62º, which is quite high. Consider removing the OC to preserve your settings. You can save a configuration file from the BIOS to avoid losing progress. Then verify the temperatures—if they stay under 58º, it suggests you need a more efficient cooler.
I'm having issues with stress testing under default configurations since the load line calibration is set to auto, causing the voltage to vary excessively. This leads to the CPU clock oscillating between 3.5 and around 1.7 GHz. The temperatures remain comfortably below 40 due to these fluctuations.
Run Prime95 to stress-test the CPU for one hour. The voltage fluctuations are acceptable; maintain the maximum of 1.5 for the CPU. Exceeding this level requires liquid cooling to handle the high voltages.
Andy0432 is experiencing issues with stress testing due to auto-calibrated load lines causing voltage instability, leading to CPU clock variations between 3.5 and 1.7 ghz. Temperatures remain below 40°C thanks to these fluctuations. He advises against using P95 for more than 10 minutes on small FFTs, as it can overstress the CPU. Suggested alternatives include AIDA64 for sub-system testing and Realbench for real-world validation. If voltage droop occurs under load, setting LLC to high is recommended but should be moderate. Adjusting the BIOS's CPU current capability to 120% may also help. The frequency instability is linked to Turbo boost being enabled; using a fixed frequency is advised. Other BIOS adjustments can further stabilize performance.
