Make sure you are using at least 2 threads. If only 1, then your GPU is not 100% loaded. 1 thread solution is good if you plan to do other stuff with your card. Imagine it as being an intensity switch.
We reached 440 with 115W TDP limited card that has OC set to 2120 core and 4700 mem. With next version, it is about 445 with these same settings.
Another example is 126W TDP limited card, OCed to 2110 core and 4400 mem (micron with BIOS patch) reaching 440 sol.
You can view how far is your card OCed when you launch excavator with overclocking set.
yeah i'm running it with -ca -ca , three thread result in a crash
how can you consume only 115 watt with core 2120? it's impossible to set the gpu at 2120 core with 60% tdp, without having a crash
what you have set on the core? the only thing may be the mem, your is at +900 mine only 600
Due to limited TDP, core is actually at around ~1820. Watt measurement is sw - from excavator or nvidia-smi, not HW one, so HW one is a bit higher.
