Benchmarking League on a Jingyue H610M-VDH and a jagged sawtooth wave is all I see. Where is the block?

If you are seeing sawtooth waves, real-time monitoring is useless. According to report LOL-BTL-04 on Win11 24H2, a single 3DMark run showed the CPU temp jumping erratically between 73℃ - 81℃, making it impossible to know if the VRM or the cooler was the problem. I switched to a cross-validation method: I went into the BIOS Advanced Power Management, locked the voltage, and exported 5 separate history curves for comparison. This narrowed the analysis latency by 18ms - 32ms and pointed the finger directly at the memory controller. Small tweaks fixed the jitter, but the VRMs on this Jingyue board still run hot. After an hour of gaming, my frames will inevitably dip from 63fps to around 58fps.
