Hi People,

After testing a few of Claymore's releases, I have found out that some variables are better than other, with some giving an increase in profit while others offering some potential profit in the future, if these coins are kept "in the vault".
All tests have been documented and I want to share these results with you, in the following lines:

Claymore's Dual Ethereum+Decred AMD GPU Miner
Power Consumption


The following test shows the approximate power consumption (from wall) for each of 5 steps in the Claymore’s Dual Ethereum+Decred Miner using Catalyst 15.12.
This test only approximates the power usage of 1 rig and may not be a valid way of calculating your exact power consumption, due to component variables, Volt input (test was made on 230V line), overclock and component life.

In order to demonstrate how this mining test will perform, all clock/core speeds are set to stock, only temperatures and power consumption will be monitored during this test.
Temperatures are high because I usually under volt Core and under clock Memory for GPU1 (r9 290)
(-100mV/1000Mhz – Temp ~79*C/~69*C/65*C)
Also, Ambient temperatures are at around 17*C, but cards are not very well ventilated (working on it)

Conclusion:
Please note that these tests have been conducted with a fee of 2% in mind. Shares have not been calculated due to the fact that they can be influenced by internet provider, proxy and other factors.

The command line –decri 100 does not provide my rig with any beneficial output over ETH when mining DCR, while draining 1040W/h from the wall, it only provides an additional ~470Mh/s for DCR, but at the cost of minus ~10Mh/s ETH.
Also, mining on regular ETH could not be that beneficial also, since profits drop by ~13-15%.

Calculations per Month have been made using ETH calculator:
http://karldiab.com/EthereumMiningCalculator/
And DCR calculator:
http://decred-calc.cryptohub.info/

If you plan on building a new rig, please take into consideration the following calculations for your GPU/PSU, using more than one reference for GPU power draw on full load (https://forum-en.msi.com/faq/article/printer/power-requirements-for-graphics-cards):
Eg. Radeon R9-290 - 31A and a 550W psu minimum
Meaning: ~Full load r9 290 may draw 31A

31A*12V=372W from the 12V rail.

1A for the 12V rail (PCI-e power) means 12W / 1A*12V=31A
2*r9 290 might draw up to ~744W
3*r9 290 might draw up to ~1116W
4*r9 290 might draw up to ~1488W
5*r9 290 might draw up to ~1860W
6*r9 290 might draw up to ~2232W
~ Depending on clock speed, core speed, voltage and temperature

For this example (31A on 6+8pin PCI-e connector) you will need a good power supply that can provide a minimum of 16A for each rail.

Other Graphic Cards can differ greatly, drawing more power from one 8pin connector
(Asus Strix 380), which draws 28A from one rail, with a minimum recommended PSU/1GPU of 500W

With these in mind, please note that using Claymore’s dual Miner can affect your Amper (A) power draw and may lead to permanent PSU damage!!!
