The 9070 series seems a bit strange when it comes to overclocking. You'll be strictly getting your gains from undervolting, raising the power limit, and memory overclocking but NOT from raising the GPU core frequency. The latter seems to do absolutely nothing.
A quick guide:
Using AMD Adrenalin (should be installed already if you own an AMD card), go to the tuning section. Raise the power limit to the max which should be +10%. Now start to overclock the memory by 25 mhz intervals. After each increment, test the overclock using 3dMark (Time Spy and Steel Nomad) and Superposition. Both of these apps are free GPU benchmark programs which can be found on Steam and with a Google search, respectively. With the memory OC, you'll start to see your scores increase and then peak, and any further increment will start to decrease your score. This inflection point is where you want your memory frequency to stay at for max performance. Realistically you might want to start the frequency test at around 2600 because most seem to easily hit over 2700 mhz with beneficial performance uplift.
Now, start to lower the voltage frequency at about a 20mV increment. This is where you'll see the biggest performance uplift. Do the same benchmark tests as before. Keep doing this until you reach a point where the AMD software or benchmark crashes. Increase the mV by 5 mV until you reach a point where no benchmark app crashes. Give yourself an additional buffer by increasing it another 20 mV to be safe.
I managed to reach an UV of -145mV and it seemed stable. But then got crashes on certain games and the Steel Nomad benchmark. I ended up raising the UV to a total of -100mV where it now seems stable. You won't know how stable your UV is until you play many different games.
I don't have an XT but my 9070 is now performing at an XT level. My overall performance uplift seems to be around 12% - 13% compared to my stock settings. I'm pretty happy with that, given I was sour about not being able to land the XT version. Lol.
