Uncacheable speculative write combining
USCW stands for Uncacheable Speculative Write Combining. It is a computer BIOS setting for memory communication between CPU and graphics card. It allows for faster communication than the Un-Cachable setting, as long as the graphics card supports write-combining, which most or all modern graphics cards do.
Write-combining allows data to be temporarily stored in write combine buffers (WCB) and released in burst mode instead of writing single bits. See write-combining.
