How to stop Onda A520-VH-W from rebooting in Deathloop?
Right in the middle of a loop transition, my PC would just black out and reboot without warning. It's honestly pathetic how poorly some budget boards handle voltage. The Onda A520-VH-W was suffering from a 0.08V Vcore drop during transient loads, which triggered the CPU's internal protection. I tried disabling virtualization in Windows, but that was a total waste of time—it didn't stop the crashes and just broke some of my background apps. I finally went into the BIOS and set a manual core voltage offset of +0.05V and strapped a tiny fan onto the VRM heatsink. I ran Prime95 for 5 hours straight and didn't hit a single error; the reboots are completely gone. I actually tried +0.1V at first, but the temps spiked to 95℃, so I had to dial it back to +0.05V to find the sweet spot. CPU temps are now stable at 75-82℃. I exported the BIOS profile so I don't have to do this again, and the fans are steady at 2000-2200 RPM.
