Overclocking
When it came time to test the overclocking capabilities of MSI's Z270 GAMING PRO CARBON, I found the Z270 GAMING PRO CARBON to offer up everything I asked of it without any problems, including keeping power consumption to a minimum while pushing up the CPU clocks. I wasn't sure whether my 3866 MHz memory sticks were going to work well with the MSI Z270 GAMING PRO CARBON, but was pleasantly surprised when I enabled their XMP profile and the board booted right up after a reboot to save the change. I then set my chosen CPU clocks and voltages and everything worked perfectly. If you want to push a bit higher than I did here, the board is clearly capable of higher CPU clocks, and maybe some better memory overclocking too, but I doubt we'll see many needing more than a 5 GHz CPU clock and 3866 MHz on the memory at the same time. :P
However, there is a problem: there are no adjustments available for the Cache/Ring domain, which leaves a part of performance tweaking out on the table, waiting to be used properly. This omission of functionality will limit the ability to capitalize on high memory clocks, but anything up to 3200 MHz will be fine since most CPUs have the ability to scale up Cache/Ring speeds on default voltages.
