System stops unexpectedly during high-load testing despite stable temperatures.
System stops unexpectedly during high-load testing despite stable temperatures.
It seems the temperature isn't the issue; your voltages are decreasing more than expected. A 0.1V drop in your 12V suggests a likely problem, possibly an undervoltage condition. If you can't test another power source right now, consider reducing the voltage to the CPU.
Voltage drop is typical when under load, but why yours drops significantly is unusual. You might lower the drop by adjusting your load line calibration settings in BIOS and raising them slightly. You probably don’t need to push them all the way to maximum—just one of the middle options should suffice. Maximum settings are meant for extreme overclocking scenarios. This issue seems limited to synthetic tests, which stress the hardware more than normal use, leading to greater voltage drop than usual. If your 12V rails are all dropping similarly, crashes could occur during games or even while browsing or idle.
Have you tested a different power supply unit? Is it 80+ certified?
I checked the BIOS for load line calibration on my ASUS board but didn’t find anything matching. A search through the bar was thorough, and I tried XTU to perform the calibration but it reported an undervolt protection issue. It’s confusing.
