I have been running my card with everything “cranked to the max” so to speak, to the point that I am essentially software limited.
I have my power limit set to 150 W + 20% (180W) using MPT. With core TDC set to 120 (which also scales with the power limit slider I believe, but I wanted slightly more headroom). I should note that my cooler cannot sustain 180W for more a few minutes, but for occasional spikes when needed, it adds some stability and higher clocks compared to say, 150W. Also in MPT I have memory timing control set to 2 to have slightly faster VRAM.
In Adrenalin, I have memory set to 1900 with the “Fast Timing Level2”.
Core is where things get interesting. For the longest time my sweet spot in stability was 1020 mV with 2800-2900 MHz. However a few months ago I was able to push this to a (frankly alarmingly) low 975 mV. I will concede that I did lose stability in synthetic loads like Furmark, however for daily usage, the reduced power draw is welcome.
In terms of benchmark scores I had an anomalous peak graphics score almost a year ago at 9723 in timespy (rank #22 as of writing). For whatever reason I have not been able to replicate this and more recently I have only been able to get scores closer to 9400-9500. https://www.3dmark.com/spy/34468812
In terms of stability, I found that, interestingly enough, warmer is better. On occasion, if my card is below ~35 C° (roughly what it idles at), I will get driver crashes if a significant load is put on the GPU. Additionally, for minimum clock speed, if I set it below 2700, I will usually crash the driver even under no load with these UV/OC settings.
Overall, I am aware that I got rather lucky with my silicon, as I have a roughly ~15-25% boost in real world performance depending on the task (not quite jumping up a price tier but definitely closed the gap significantly). In addition, I would dare to say that I could quite comfortably push the card beyond the software-bound clock limits, if I were able to. As far as I am aware, the ability to modify these limits is locked down; feel free to correct (and inform how).
I got inspired to run a Timespy (with the 975 mV 2700-2900 MHz) with a graphics score of 9553. (However for some reason my CPU is misbehaving and scoring significantly lower than it has in the past…) https://www.3dmark.com/spy/43608035
