To overclock the Aorus, you don't need to adjust the clock settings as much as the power level. At least with my Aorus Xtreme 1080 Ti, the card itself overclocks automatically while mining, and will use whatever available power there is set in the Aorus app. Definitely use the Aorus app for these cards, if yours is like mine, because the max power settings are much higher than you'll get out of MSI. If you want to visualize what I'm talking about, load up nvidia inspector and look at the power draw and clocks, and your hashrate - then raise the power level in the Aorus app and watch the clock speeds increase with the power levels.
Your mileage may vary, obviously, because it's a different card, but I would bet that Aorus uses similar software across all the xtreme card lineup.
As a side note, I have overclocked my Aorus to death trying to get boosts in hashrate from clock and memory speed adjustments. Memory speed helps a tiny bit, but the only real difference (and only stable method) I found was adjusting the power.
