How to stop Vcore drops on Jginyue X99M-PLUS D4?
The power delivery on this board is a straight-up nightmare. Walking through English cities, my FPS would plunge from 60 to 20—it made me want to smash my keyboard. The VRM on the Jginyue X99M-PLUS D4 was hitting 110℃, causing the Vcore to tank from 1.2V to 0.9V instantly. I tried stuffing the case with fans, but it only dropped 5 degrees, which was a completely useless effort. I finally went into the BIOS and forced a Vcore offset of +0.05V and strapped a 4cm fan directly onto the chokes. In Cinebench R23, my multi-core score jumped from 21,000 back up to 24,500, with voltage swings held within +/- 0.06V. I actually had a thermal reboot after the first voltage bump until I cranked that tiny fan to 5000 RPM. VRMs now stay at 88-94℃ and the CPU at 75-82℃. I exported these settings just to make sure I don't have to do this again, and it finally feels responsive.
