Overclocking
Intel has locked CPU overclocking on the W480 chipset. The BCLK can still be modified, and Gigabyte has also included all the expected voltage configuration options.
For memory overclocking, the Gigabyte W480 Vision D did well, reaching 4000 MHz stable at XMP timings and voltages on my Trident Z Neo kit.
Gigabyte has a feature that auto-tunes the memory timings to maintain stability when overclocking. While I disabled it for my test to keep the benchmark standardized, I think this is a great feature for new overclockers because it gives them a starting point for their manual tuning.
