How to fix voltage drops on ASRock A320M-HDV R4.0 in ME: Legendary?
Every time I hit that galaxy jump, the smoothness just vanishes and I get this brutal stutter that's honestly eye-searing at 4K. Checking HWInfo, the VRMs on the ASRock A320M-HDV R4.0 just can't handle the transient CPU spikes, causing Vcore to swing wildly between 110-150mV, which makes the clock speed jump erratically between 3.2GHz and 3.8GHz. I tried the 'High Performance' power plan first, but that was a nightmare—the VRM temps shot up to 92℃, triggering an even worse thermal throttle. I eventually crawled into the BIOS and set a manual CPU core voltage offset of +0.03V and cranked my front case fans to 1600 RPM to keep the power delivery cool. In HWInfo, the voltage ripple finally settled under 40mV, and the frame time stopped jumping from 15-45ms and locked into a flat 16.6ms line. I actually overshot the offset at first and the system just hard-rebooted during a save load, so I had to dial it back to +0.02V to find the sweet spot. Core temps stayed around 68-75℃. It's a bit of a workaround, but the frame delivery is finally consistent.
