Tom's Hardware - Are those stains normal on a gpu's back? “Exactly, residue. Some manufacturers like ASUS usually washes the residue (flux, coatings) after the final product is done, some manufacturers like Gigabyte are notorious for large blobs of flux still present in the final product (don't know about their current crops).”

System and driver support for Resizable BAR:

It is typical today for a discrete graphics processing unit (GPU) to have only a small portion of its frame buffer exposed over the PCI bus. For compatibility with 32 bit OSes, discrete GPUs typically claim a 256 MB I/O region for their frame buffers and this is how typical firmware configures them.

On GPUs that support a resizable base address register (BAR), Windows will renegotiate the size of a GPU's BAR after firmware initialization in Windows Display Driver Model (WDDM) v2 and later. (…)

This renegotiation is mostly invisible to the kernel-mode driver. When the renegotiation is successful, the kernel-mode driver will observe that the GPU BAR has been resized to its maximum size to expose the entire VRAM of the discrete GPU.
