Some GTX 1060 3GB cards have low hashrate with Ethash coins.

Ethash algorithm behaves a bit strange on my mining rig with HiveOS and 8 GTX 1060 3GB. Four MSI ARMOR cards with Sumsung memory (OC +1500 mem) have 24+ MH/s, two other cards (OC +600 mem) have 21+ MH/s and two other slow MSI cards (also OC +600 mem) have only 18+ MH/s. I tried to switch risers, PSU, PCI slots and move the cards across rigs, but with no success.

Today I did a pure experiment. I plugged one of the slow cards to a Windows 10 machine with 1000W PSU directly via PCI slot without riser, started Claymore Miner with Musicoin (that has a lower dag size than Ethereum) and got the same result as before, without OC the card had 15+ MH/s (normally it should be 19+ MH/s):

Mining Ethereum on Ubuntu 18.04 with GeForce GTX 1060 3GB

I am not a Linux expert, so it took me some time to configure my mining rig on Ubuntu 18.04 with NVIDIA GeForce GTX 1060 3GB, and I wrote down all the steps I did:

First I installed NVIDIA driver, but OpenCL did not install automatically with it and I installed it manually with the following command:

sudo apt install -y ocl-icd-libopencl1

Then I installed CURL:

sudo apt install -y libcurl3

not ‘curl’ and not ‘libcurl4’ packages, otherwise the miner will fail to start reporting the following error message:

./ethdcrminer64: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by ./ethdcrminer64)

It is no more possible to mine Ethereum using 3GB graphic card on Windows 10

I mistakenly believed that 3GB of video memory is enough for mining, while EthDcrMiner64.exe does not work with 3GB on Windows 10 and reports the following errors:

GeForce GTX 1060 does not trigger the boost state (Solved)

MSI GeForce GTX 1060 3GB graphic card does not trigger its boost state when its GPU is loaded at 99-100% with NiceHash miner. Compare the values in the green rectangles:

Fun with Bitcoin mining on a home Windows machine.

I have heard many times that there are a lot of Russian guys who build mining farms and earn money with cryptocurrencies. Who knows, probably cryptocurrencies are still only at the starting point of their growth, or probably it is too late to start mining, or as another alternative Russian government will forbid them, but anyway it was interesting for me, how much Bitcoins my home Windows computer with relatively old graphic card can mine.

I overclocked my GeForce GTX 750 graphics card a bit:
