How to stop thermal throttling on Jginyue X99M-PLUS D4 in Red Dead Redemption 2?
Seeing Saint Denis in full 4K detail was amazing for about ten seconds until the massive frame drops hit and brought me back to reality. The cramped layout of the Jginyue X99M-PLUS D4 causes heat to soak into the VRM area instantly; I saw CPU temps jump from 65℃ to 97℃ in just 12 seconds, triggering a brutal clock speed drop. I tried 'Power Saver' mode in Windows, which dropped temps by 8℃ but crashed my FPS from 60 down to 35—a total disaster. I eventually flipped my case fans to a high-pressure exhaust setup and manually set the CPU power limit to 115W in the BIOS, capping the max temp at 85℃. Looking at the RTSS graph, the frame time stabilized from a wild 18-50ms swing down to a consistent 14-18ms. I actually set the power limit too low at first and the game just froze during a save load, so I had to bump it back to 115W to get it right. CPU temps now hover between 78-84℃ with fans screaming at 2200 RPM. It's loud, but the stuttering is gone.
