Instructions for Cpuminer-opt - set up a miner for mining cryptocurrencies on a cpu

Used is zergpool for converting directly to ETH. All the mined coins are transferred directly to ETH wallet:

If you want to donate or support, simply mine for some seconds some blocks with the command line above, during your tests. Every bit helps.

Config example for Dogecoin

This is how the ready-made bat file example CpuMiner for Dogecoin will look on the dogeminingpool:

Just replace DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo with your own Dogecoin wallet address.

Example:

cpuminer-sse2.exe -a scrypt -o stratum+tcp://dogeminingpool.com:3009 -u DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo.0 pause

If you want to understand how to set up everything from scratch, then you need to enter 5 commands one by one:

1. cpuminer-sse2.exe - the name of the program we run
2. scrypt - algorithm for mining
3. dogeminingpool.com - pool address
4. 3009 - pool port
5. DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo - the address of the wallet for mining on the exchange.

To set up a batch file for solo mining, we need to run the wallet in server mode with port 9999 and enter other commands:

cpuminer-sse2.exe -a scrypt -o http://127.0.0.1:9999 --coinbase-addr DKs5E8nWJe2E5vYnVSoYqNjw2T17nGYUDo 
pause

Here we added --coinbase-addr - used for solo mining.

You can try adding the rpc resolving IP to create .conf file To allow connections only from your local network, you can specify your subnet in the rpcconnect parameter. You also need to specify the internal IP address of the machine you are connecting the miner to in rpcconnect. Then start the wallet in server mode and use the wallet IP, rpcuser, rpcpassword and rpcport in the miner config file.

Setup for NiceHash

Here is a batch file for NiceHesh:

cpuminer-sse2.exe -a scrypt -o stratum+tcp://scrypt.eu-west.nicehash.com:3333 -u 3HHG3zpxP4AmbKDR9iRy1c2bqAb4WKhNwm.0

Commands

--algo or a short synonym for this command -a - Selects the mining algorithm.

Important! Use either a long synonym --algo or a short one -a. You do not need to use this and that together.

Further commands will be separated by commas. First a short synonym, and then long. Remember to use only one variation.

-h, --help - display help information and exit

-v, --version - Display version and exit

-c, --config \<config file path> - Use config in JSON format instead of batch file (CMD file).

To launch cpuminer-sse2.exe from the config.txt configuration file, enter in the console: cpuminer-sse2.exe -c config.txt

Use the file config_example as a starting point to create your own configuration.

3.19.6

3.19.5

3.19.4

Fix verthash memory allocation for non-hugepages, broken in v3.19.3.

New option stratum-keepalive prevents stratum timeouts when no shares are submitted for several minutes due to high difficulty.

Fixed a bug displaying optimizations for some algos.

3.19.3

• Linux: Faster verthash (+25%), scryptn2 (+2%) when huge pages are available.
• Small speed up for Hamsi AVX2 & AVX512, Keccak AVX512.

3.19.2

• Fixed log displaying incorrect memory usage for scrypt, broken in v3.19.1.
• Reduce log noise when replies to submitted shares are lost due to stratum errors.
• Fugue prehash optimization for X16r family AVX2 & AVX512.
• Small speed improvement for Hamsi AVX2 & AVX512.
• Win: With CPU groups enabled the number of CPUs displayed in the ASCII art affinity map is the number of CPUs in a CPU group, was number of CPUs up to 64.

3.19.1

• builds for CPUs with AVX or lower have CPU groups disabled,
• zen3 build renamed to avx2-sha-vaes to support Alderlake as well as Zen3,
• zen build renamed to avx2-sha, supports Zen1 & Zen2,
• avx512-sha build removed, Rocketlake CPUs can use avx512-sha-vaes,
• see README.txt for compatibility details.

• Other minor fixes.

3.19.0

• PR#346: Fixed incorrect CPU affinity on Windows built for CPU groups,
• added support for CPU affinity for up to 256 threads or CPUs,
• streamlined code for more efficient initialization of miner threads,
• precise affining of each miner thread to a specific CPU,
• added an option to disable CPU affinity with --cpu-affinity 0

3.18.2

Issue #342, fixed Groestl AES on Windows, broken in v3.18.0.

AVX512 for sha256d.

SSE42 and AVX may now be displayed as mining features at startup. This is hard coded for each algo, and is only implemented for scrypt at this time as it is the only algo with significant performance differences with those features.

Fixed an issue where a high hashrate algo could cause excessive invalid hash rate log reports when starting up in benchmark mode.

3.18.1

More speed for scrypt:

• additional scryptn2 optimizations for all CPU architectures,
• AVX2 is now used by default on CPUS with SHA but not AVX512,
• scrypt:1024 performance lost in v3.18.0 is restored,
• AVX512 & AVX2 improvements to scrypt:1024.
• Big speedup for SwiFFTx AVX2 & SSE4.1: x22i +55%, x25x +22%.

Issue #337: fixed a problem that could display negative stats values in the first summary report if the report was forced prematurely due to a stratum diff change. The stats will still be invalid but should display zeros.

3.18.0

Complete rewrite of Scrypt code, optimized for large N factor (scryptn2).
