DNR 0.000150
100% - 819 MH/s 87.6 DNR = $36.46 - 6.03 (2093 watts) = $30.43 per day
70% - 748 MH/s 80.0 DNR = $33.30 - 4.00 (1390 watts) = $29.30 per day
96% of the profit come from the first 70% TDP.
People running at 100% are basically wasting 703 watts of electricity.
Not including the extra cooling cost to run at 100%.
SIGT 0.000012
70% - 336 MH/s 1220 SIGT = $40.63 - 3.92 (1360 watts) = $36.71 per day
*DNR calculation are ruff estimates based on the earnings from the past 5 hours of mining.
Watts are measured from the wall.
Measure wattage at wall NOT TDP. TDP is not a number that's set in stone. It varies by models, brand, and manufacturer. In addition to that you can have an algo that will use 78% TDP. That means when you're running at 70% you're only reducing power by 8% (once again this varies a lot) and when you increase it to 100% it DOES NOT use 100% of your available TDP as the algo does not use it.
Even if say the algo is using up to 100% TDP and you increase it from 70% that does not also mean it's using 30% more power. Certain algos use more power then others and in different ways. That means a 30% increase could only be using 15% more power measured at the wall.
All the wattage above were measure from the wall with a Kill-A-Watt meter. I even specifically said "Watts are measured from the wall." in the post.
Most fully optimized algorithms will use up to 1400 watts at 70% TDP, that's true for DNR (1390), SIGT (1360), and ZEC (1400).
The highest I've test for at 100% TDP is 2200 watts on EWBF ZEC. DNR is using 2093 watts at 100%.
When you spend money to buy 21 x 1080 Ti, you do test to find optimized settings. If people want to run them at 100% that's completely up to them.
I'm just putting out results that I have found best.
