Mining NEOXA on HiveOS with 3GB cards

The key to the success in mining NEOXA on HiveOS is knowing pool parameters that can be stratum+tcp://minenice.newpool.pw:1120, for example:

Nvidia 3GB mining is still alive

Today I started to mine BTG on my 3GB farm. The miner consumes about 1.7MB on HiveOS:

BTG did 3X in April and theoretically it can be the most profitable coin on 3GB cards.

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):

Molten SATA power connector on a mining rig.

I have a mining rig with 8 GTX 1060 3GB connected via risers, the risers are connected via SATA power connectors to Corsair HX850. When the rig stopped working I noticed that one SATA connector on the PSU is molten:

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:

Setting up ASUS PRIME H270-PLUS motherboard for GPU mining

To make ASUS PRIME H270-PLUS motherboard work with 8 video cards the following BIOS options should be set:

  • Advanced\System Agent (SA) Configuration
    • Above 4G decoding [Disabled] -> [Enabled]
    • DMI/OPT Configuration\DMI Max Link Speed [Auto] -> [Gen1]
    • PEG Port Configuration\PCIEX16_1 Link Speed [Auto] -> [Gen1]
  • Advanced\PCH Configuration
    • PCI Express Configuration\PCIe Speed [Auto] -> [Gen1]
  • Advanced\APM Configuration
    • Restore AC Power Loss [Power Off]->[Last State]
  • Advanced\Onboard Devices Configuration
    • HD Audio Controller [Enabled]->[Disabled]
    • M.2_1 Configuration [Auto]->[PCIE]
    • M.2_2 Configuration [Auto]->[PCIE]

probably not all of these settings are strictly necessary, but at least I was able to connect 8 video cards GeoForce GTX 1060 with them:
