These stability tests aim to catch any immediate causes for memory or CPU errors.įor manual overclocks, based on the information gathered from the previous testing, starts off at a nominal voltage and CPU multiplier, and the multiplier is increased until the stability tests are failed. We select the automatic overclock options and test for stability with POV-Ray and OCCT to simulate high-end workloads. Our standard overclocking methodology is as follows. The Command Center software proved functional for our uses in overclocking allowing a quicker turnaround than rebooting to the BIOS to change different settings. The BIOS had all the required options to successfully and safely push the i7-8700K past the 5 GHz threshold. Overall overclocking on the Z370-A Pro was as easy as any other unlocked Intel processor. At 5.1 GHz I had to use a little more voltage (0.025V) than what the other boards average for stability in our testing, but, this could also be due to the not always precise software readings (the board does not have voltage read points). There was little to no vdroop while using auto so it was left at that setting. With manual overclocking, the Z370-A Pro was able to match other more expensive boards in overclocking reaching 5.1 GHz.
Performance improvements from 100 MHz aren't typically tangible to most users, but the more the better regardless. The board set the voltage at 1.2V which was an acceptable value for the clocks (specifically the 4.8 GHz single core). This yielded 4.4 GHz all cores and 4.8 GHz single core. In this case, the Z370-A Pro raised clocks by 100 MHz all around. We have seen in the past, across all AIBs, that these one button overclocks tend to do very little and/or raise voltages to levels not needed. MSI motherboards in the non-Pro series use their Gameboost functionality to 'one-touch' overclock. That said, the board and its power delivery system were unphased at the end of testing handling the 5.1 GHz overclock. Being a board designed for business (and is good for mining according to the webpage), overclocking prowess isn't generally in the cards, particularly at towards the limits.
