Uncacheable speculative write combining
Uncacheable speculative write combining (USWC), is a computer BIOS setting for memory communication between CPU and graphics card. It allows for faster communication than the "un-cachable" setting (the alternative to USWC in the computer BIOS), as long as the graphics card supports write combining, which most or all modern graphics cards do.
