Managing Electricity Costs

[ArtfromFL]

Hi All,

I am mining ETH on a 6 card rig (RX 570 8 gb) using Win 10. Using Claymore 11.8 with Adrenallin 18.5.1.
According to the Kilowatt meter I am drawing a total of 800 watts from the wall. Using AF, my settings are Core 1150, Memory 2175 and Voltage 900.
My calculation shows a usage of 560 KWh a month.

Is there anything else I can do or adjust to bring that number lower 
Thanks for any idea or advice.

The power meter at the wall is going to be the more accurate of the two.

There are a couple things you can do...

1 - ETH isn't always the most profitable coin to mine and it uses a lot more electricity than coins based on the cryptonight algo.
2 - Not every card is created equal, even those by the same manufacturer and same memory. You need to tweak each card individually. It is unlikely you are getting the best hash rate / best power usage setting per card by setting them all the same. Also, these setting vary based on the coin you mine also.
3 - You have to evaluate is that extra .1 or .2 MH/s worth the 30 or 40 watts you just added by maxing out your OC.

The only way to bring it down is either to bring down the core clock a bit or to mine a different algo like CryptonightV7 which consume less energy than Ethash.

I would say to you to continue mining even if you are not in big profit, or are breaking even or even in the worst case of going into negative territory by the end of the month because price of coins may go up and you may end up in big profit.

Have you any experience with BIOS Flashing your 270s? A buddy of mine flashed his 270s to 280s and managed to get better efficiency (Hash/watt) than standard 280s.

You can also try to undervolt your miner so that you can decrease the power consumption and I think you must check some other altcoin if what coin is more profitable than ethereum.
For now here in my country, the electricity rate is high but still waiting for the coins to increase its value this coming months to make a good profit.
I just holding then sell them in the right time to make a profit.

As the other comment said, Undervolt would give you a bit lower power used, and some different algorithm may be giving you less power consumption. In the end, this is related to power cost, so you can stay at that power used but increase the profit with mining more profitable coin than the current coin.
