Fixing power delivery issues on Jginyue X99M-PLUS D4 for F1 25?
Absolute disaster. I can't believe an X99 board let my CPU trigger thermal protection and crash right in the middle of a race. The Jginyue X99M-PLUS VRMs were hitting 108-114℃ under load, causing the core voltage to dip by 0.12V and triggering a hard shutdown. I first tried limiting the CPU to 115W via software, but my FPS tanked from 100 to 65—I refused to accept that kind of performance hit. I ended up rebuilding my case fans for forced exhaust and set Load-Line Calibration to Level 3 in the BIOS. OCCT stress tests showed the VRM peak dropped from 114℃ to 84-89℃, and the crashes stopped completely. I did get some weird vibration noise from the chassis after the fan change, but some silicone pads fixed it. CPU cores are stable at 78-84℃, and the BIOS confirms the board stays around 44-52℃. It's a beast of a board, but the cooling is a struggle.
