Huntkey Blizzard T620 OCP crashes in Red Dead Redemption 2?
I spent a fortune on this rig, only for it to black screen and reboot ten minutes into 4K mode. Absolute garbage experience. The 12V rail on the Huntkey Blizzard T620 was seeing 80-110mV ripple spikes from my RTX card, which tripped the OCP (Over Current Protection). I tried capping power to 80% in software, but I lost 15% performance and it still crashed occasionally—a total waste of time. I used MSI Afterburner to switch from auto to manual voltage, dropping 1.05V down to 1.02V and locking the power limit at 400W. 3DMark stress tests passed 20 loops without a single error, with temps at 68-74℃. I actually crashed twice during the undervolting process because I went too low, but adding 0.01V back in stabilized everything. PSU fan is humming at 1200 RPM and internal temps are 42-46℃.
