Eliminating Power Supply Noise and Verifying Hardware Status on MAXSUN B850M

I noticed that during peak load scenes, my rig would develop this annoying high-pitched whine that seemed to sync with frame drops, which is a classic sign of electromagnetic interference leaching into the data rails. Swapping fans was a waste of time until I looked at my cluttered cable nests and realized the power cables were practically hugging the high-speed data lines. I went into the BIOS, swapped the power response to a more conservative mid-tier setting, and spent an hour rerouting every single cable to ensure maximum physical separation. Using HWinfo64, I monitored the Vcore ripple, which smoothed out to a tight 5mV - 12mV range, and the stutters vanished. Did this totally fix the rig? Mostly, though I still catch a whiff of coil whine in the most taxing environments. It was a real eyes-opener; I had spent days tweaking software when the answer was physically reorganizing the hardware. It is lauding to think a few cable ties could be the key, but for high-stability builds, physical layout is everything.
