Today, ASRock gets another bite at the value-supremacy apple with its Z170 Extreme4, the next model down from the Extreme6. The Extreme4′s largest downgrade appears to be its loss of the add-in SATA controller in Extreme6. We’re even treated to the same I/O panel configuration, with its six USB 3.0 ports, two USB 3.1 ports, triple video outputs, full array of digital and analog audio connections, and handy CLR_CMOS button. ASRock’s Z170 Extreme4 is cheaper than the previously tested Extreme6, but is it also a better value? We examine the features and push our overclocks to find out!
