The budget Ethereum mining rig gets an upgrade. We’re now over 50 Mh/s using 4 x MSi R7 370 graphics cards and a updated motherboard with plenty of pcie connectors.

Testing the updated Nicehash miner V1.6.1.4

If you’ve not used the Nicehash miner before I’ll quickly explain how it works, because it’s a little different to other mining software. Nicehash is not just a miner, it connects to a market of buyers and sellers of hashing power and so when you mine using the Nicehash miner it will mine the most profitable coin with your hardware and then sell this on the open market in exchange for Bitcoins. So you can be mining Ethereum but you’ll actually be paid in Bitcoin.

Download Link – Nicehash Miner V1.6.1.4

Once you have downloaded and extracted the zip file to a folder of your choice, click the NiceHashMiner.exe to get started.

nicehash-folder

In the main window you’ll need to add your own bitcoin address and worker name as reference you can use to see your stats online. Then you want to click the Benchmark button.

nicehash-main

The benchmarking process tests your computers hardware to see how it perform when mining different coins and this data can then be used by Nicehash to decide which coins to mine and when for the best overall profitability.

Here’s the benchmark results from my two R7 370’s and you can see the coin algorithms in the center and hash speed on the right. The bench mark can take sometime to complete, a few minutes for each algorithm.

nicehash-benchmark

Once the bench is complete you can close the window and return to the main miner window.

Select the hardware you wish you use and then click the Start button. The miner will choose which mining algorithm is the most profitable and then start up the mining software for that coin. In my case Ethereum (DaggerHashimoto) is selected and the mining begins.

After a short period of time you’ll see the earning summary being update and this confirms your hashrate and expected daily earnings and also your bitcoin balance at Nicehash. (payouts are done 3-4 times a day).

In testing I did notice that mining Ethereum using Nicehash the hash rate was 27.25 Mh/s and this is a little slower than the 28.08 Mh/s when using Claymore’s Dual Eth miner in Eth only mode. However the difference is a minor consideration when compared with the benefit of auto exchanging for Bitcoin.

Overall the miner performs well and should provide decent profits to miners without the hassle of switching mining software to match the days most profitable coin.

Testing SGMiner 5.4.0 performance using 2 x MSi R7 370 4GB AMD GPU’s

I recently did a post on using the Marlin miner at the Siamining.com pool and in this post I wanted to do a comparison using another pool and different mining software.

SGMiner has been extensively tested and developed and is one of the most popular miners due to it’s performance and also the wide range of algorithms it supports. This miner can be used by Nvidia and AMD graphics cards.

Today we’re using a custom version which is best suited for use mining Siacoin and it can be downloaded using the link below.

I tested the miner at the Suprnova pool and had my batch file configuration set like this

sgminer -k sia -o stratum+tcp://sia.suprnova.cc:2786 -u riskyfire.worker1 -p x -I 25

Using the 2 X R7 370’s installed in this machine and using their default clocks speeds of core 1030 memory 1400 I was able to get a average hash rate of 870 Mh/s around 435 Mh/s for each GPU.

siacoin-sgminer-default

When testing the cards with a overclocked core speed of 1150 mhz memory 1500 mhz the performance was improved by about 10% and increased the average hash rate to 978 Mh/s

siacoin-sgminer-r7-370

I did test the effect of changing the miner intensity but it didn’t seem to yield any obvious performance gains during this brief test.

I also tested this miner on another GPU a Gigabyte R9 280x using factory clocks speeds of core 1100 mem 1500 and it hashed at 910 Mh/s for comparison.

Overall this miner and pool combination performed very well and with no advantage or disadvantage in comparison to using the Marlin miner on the Siamining.com pool. A longer duration test or wider range of tested hardware might provide a better indication of the best combination but I think the time would be better spent on optimizing drivers, clock speed and voltage use to get the best overall performance and efficiency from mining Siacoin.

 

Taking a look at Claymore’s updated dual miner. This miner can mine Ethereum & Decred or Ethereum & Siacoin at the same time.
