Overclocking backup for WD Black SN850X 1TB NVMe?
During those intense tunnel renders, the WD Black controller suffered transient voltage drops that caused frequency instability, leading to visible jagged stutters. I tested two paths: simple undervolting didn't cut it—the load peaks were still too wild. I had to combine undervolting with a custom fan curve and voltage offset. That finally pinned the thermal peaks to 71 - 74°C, and the heat coming off the chassis felt way less intense. I ran a stress test and tracked the core frequency in the OC panel, narrowing the swing from 2450 - 2780MHz to a tight 2580 - 2650MHz. Power draw is still high at 185 - 210W, and the coil whine is there if you're in a quiet room. I used the cooling monitor to confirm the frequency limits are safe. Even if the BIOS resets, I've got the backup config ready to go. The initial thermal wall was a nightmare, but the second calibration made it stable.
