Why am I getting texture pop-ins and data errors on my GW3300 256GB while moving fast in Tomb Raider?

It was infuriating seeing distant ruins turn into blurry blobs of color, which completely killed the immersion during stealth sections. The Great Wall GW3300 256GB struggled with 4K texture streaming, and due to poor signal integrity on my board, I was seeing about 0.2% verification errors during peak I/O. I tried dropping the textures to medium, but the game looked grainy and the pop-ins still happened—it was clear this was a hardware-level failure. I updated my BIOS to the latest microcode and forced the PCIe slot from 'Auto' to Gen3, while slightly tweaking the voltage offset. Running AIDA64 storage stress tests, the error count plummeted from 12 per hour to zero, and textures started loading instantly. I did notice that locking Gen3 added about 10 seconds to my boot time, which I only fixed after disabling Windows Fast Startup. Drive temps are hovering between 42-50℃. After a three-hour marathon, no more missing textures, and RAM temps stayed within 58-63℃.
