Keep in mind each card is different from another, even the same brand can have different performance
In my experience, 3070 doesn't need to reduce core clock, you can measure the power consumption, there's no difference, not even a single watt, so it's better to let running without touch the core clock
My 3070 Asus Dual Fan achieve 60.8Mhs, and it's good, 140w from the wall (120w on the software)
The led screen uses only a few watts, I never measure one, but you can be sure that's less than 5w for example (I think 2 or 3w maximum)
If you are using Hive OS for example, there's a feature to disable all leds of GPUs when it's possible
What's the hashrate of this 3070?
#2 the hashrate of my aorus is about 57 mhs...
answering #3
theorically lowering the core clock results in lower consumption and less gpu heat, right?
I have a wattmeter but they are connected to my other 2 rigs
#4 I use phoenix miner
#6 how to lower core clock more? I didn't see any option to reduce it more than -502 mhz, drivers are the last ones but the swap file do you consider it is strictly neccesary with only 2 cards connnected?
