How to calibrate WD Black SN850 bus stability in Days Gone?
The textures on the wasteland buildings were just flashing into huge blocks of color, and the tearing was brutal whenever I started sprinting. Looking back at the telemetry, my WD Black SN850 1TB was hitting latency peaks of 118-142ns during high-frequency data requests. I tried forcing 'Maximum Performance' in the driver, but the flickering still popped up every 12-18 minutes, which was incredibly frustrating. I finally decided to flash the motherboard BIOS to the latest version and manually locked the PCIe link speed to Gen4 instead of leaving it on Auto. In the GPU-Z bandwidth test, my read speeds climbed from 6.1GB/s to 6.9GB/s, and the flickering stopped dead. I actually had a heart attack during the BIOS flash when a voltage spike caused a boot failure, but a CMOS clear got me back in. The chipset is idling at 44-50℃ and RAM is steady at 3200MHz. Ran three passes of MemTest86 to make sure the data transfer is clean; the compatibility glitch is officially dead.
