Much like previous generations of Intel platforms, the X299/LGA2066 allows us to apply overclocks to unlocked processors easily. Many variables can be adjusted including BCLK and ratios.

Our current record for the best overclock with Core i7-7740X is 5.2GHz. Unfortunately, sadly the ASUS board was only able to achieve 4.8GHz. To reach this point we had to modify the CPU voltage to 1.34v. Moving beyond 1.34v (regardless of the temperature) prevented us from nudging beyond 4.8GHz nevertheless this is still a reasonable result.

For a look at the ASUS BIOS, please check out the next page for a video tour of the interface.
