Should I tune voltage curves for RTX 5090 D v2 OC in TLOU2?
I spent a fortune on a 5090 only for it to black-screen after ten minutes in 8K—absolutely ridiculous. The Manli RTX 5090 D v2 OC was hitting transient spikes over 600W, triggering my PSU's OCP and forcing a full system reboot. I tried capping the power to 80% in software, but I lost 15% performance and it still crashed occasionally, which felt like a total waste of time. I went into MSI Afterburner, switched the core voltage from auto to a manual offset, and dropped 1.05V down to 1.02V while locking the power limit at 450W. In 3DMark, I hit 20 loops without a single error, with temps staying between 68-74℃. I actually crashed twice during the undervolting process because I went too low, but a 0.01V bump fixed the instability. VRAM is now sitting at 82-88℃ with fans at 1800 RPM. I've exported the curve as a backup, and it's finally rock solid.
