9070 XT underclock increased Steel Nomad Score 400 points – was my process correct?

First time OC and I'm wondering if I glaringly overlooked anything. Build is:

9070 XT Powercolor Reaper

AMD Ryzen 9 9950x3d

Arctic LF III RGB Pro AIO

G.Skill Trident Z Royal Neo 2x32GB 6000MHz CL30

Gigabyte X870E Aorus Pro

Corsair HX1000i Platinum

I used 3dmark's Steel Nomad as a way to gauge performance and measured temperatures with HWiNFO64. Final score was 7209.

I maxed powerdraw (+10%) and undervolted by 5mV at a time until it crashed at -100mV. Felt like -85mV was "stable", where I scored 7413

Next I tried various undervolts ranging from -60 to -20 while testing powerdraw between -10% to +10% to get an idea of the sweet spot. I changed voltage or power draw one at a time.

Next, I turned on Fast RAM and adjusted clock speed until I received best results at 2700MHz.

I tried offsetting Max Frequency positively but performance wasn't impacted significantly. I found a sweetspot at -300MHz.

The settings I ended with felt like the best mix of Performance, thermals, and power consumption.

Do I just need to stress test now and ss AMD Adrenalin acceptable for that?

Is there anything I drastically overlooked/do my settings seem within reason?

I haven't tested games yet, so I may have to readjust later.

Thanks for reading!
