XMP adjusts my CPU speeds on a regular basis during OCTT.
Hey, when you run stress tests with XMP enabled, the CPU clock speed drops temporarily before rising again. This behavior isn’t seen when XMP is off, where it stays steady at 5.1GHz. Your stress and memory tests ran smoothly with no issues. You might want to check if your RAM supports XMP or consider upgrading to newer models that don’t experience this problem.
Increase all power and current restrictions to their maximum values and check if it resolves the issue.
I realized something after you mentioned it—I remember now. My current PSU lacks the second component needed for extra current during overclocking, which is why I notice power throttling when using XMP settings. Is pushing power limits really dangerous? Should I just consider replacing my PSU with one that has the additional connector?
It's perfectly secure. The CPU will naturally slow down when it reaches 100°C, which is also safe under normal settings. Computer parts are built to withstand some stress, so minor abuse won't cause lasting damage. You're unlikely to destroy anything most of the time, even with high voltages—manufacturers set limits lower than what's needed to permanently harm the CPU or RAM.
I turned on XMP, adjusted the clock speed to 4.5GHz and stopped getting power throttling. I’ll keep increasing the GHz until I notice throttling again, then lower it. -Edit- At 4.8 GHz I’m not seeing any throttling. I’m considering upgrading to 3200 MHz RAM instead of my current 2666, so I might need to reduce the speed later, but this should work out. It seems my GPU can’t fully use the CPU’s overclock right now, so it doesn’t really matter.
Increase the dynamic power and current thresholds beyond just fixed frequencies
I switched off the energy-efficient turbo since it was active; the BIOS suggested turning it off during overclocking, which likely resolved the issue. What I mentioned before was too early and didn’t work, but now it appears to have helped.
