Hello Steemit.

I got interested in mining a few weeks ago, and I bought 2 GTX 1060 in order to start with the fun of being in that fairly new cryptocurrency world. As I was looking for the best hashrate for both these cards, I went into some tests that I hope will be interesting and will save some time for anyone that want to make such an investment.

First, here is the environnement I used :

Motherboard : ASUS MAXIMUS HERO VI
2 x MSI GTX 1060 3gb (dual fans) connected to the 16x PCI express
EWBF miner 0.3.4
NVIDIA Inspector (in order to overclock the cards)

Test conditions :

Everytime I changed a setting, I restarted EWBF and waited for around 10 minutes everytime for the results to stabilize
Each test reports 10 results, which are given every 30 seconds on EWBF miner
These tests are made in order to maximize the SOL/W ratio. Results would have been different looking for the best SOL/S.
Cards were running at 59 to 63°C
1 card was tested and the other was mining (So the one that is being tested is in a mining environment, with a "hot" card close to it)

First Batch

The 3 first batches of test consist in determining which parameter (memory, core clocks or power %) will act the most on the SOL/W ratio.

Memory Clock

In this test I only moved the Memory Clock from - 400 to +400 with 200 steps. I didn't do the +200 step as the function it gives is linear.

This gives pretty much a line, which coefficient is 1.25E-4 (SOL/W)/Hz

Core Clock

Same test on the Core clock, from +0Hz to +220Hz (My driver was crashing after that). Memory remain constant at -400Mhz, and Power at 70%. The results show a line that has for coefficient 7.95E-04 (SOL/W)/Hz.

Power %

Power from 60 to 90% gives a linear fonction which coefficient is : -3.40E-02 (SOL/W)/%

Conclusion

Equihash hence depends on both Core clock and Memory clock. There is also one mechanism that I still need to study : the core clocks will scale on the Power Value (%) and on the Memory Value. Hence, Core clock having more impact on the SOL/W and on the SOLS, I will have to find one more protocol to find what are the best values for this card. If you have an idea about it, please share it !

I hope these values will help you find the sweetspot of your GTX 1060. Share your feedback !
