As far as overclocking on the Crosshair VI Hero goes, it gets my hardware to its maximums with very little fuss using just some basic settings in the BIOS. You can take the time to tune down voltages for reduced thermals, but it will get to the 4080MHz-4090MHz range with full stability. Cranking it up higher allows the R7 1800X to run upwards of 4140MHz with quite a bit more voltage, but at that point, we are playing for screenshots versus looking for true stability. At least with my processor. Will this board overclock? It most certainly will and then some depending on how you plan to use it (daily driver or benchmarking only).
