xmrMiner - A CUDA based miner for Monero

xmrMiner 0.3.0 is ready for the Monero hardfork v7

This project is forked from KlausT's ccminer version. ccminer is developed by Christian Buchner's & Christian H.'s and modified by tsiv for Cryptonight mining.

If you find any bugs don't be afraid to open an issue.

Requirements/ Install


The optimal parameter for --launch=TxB depend on your GPU. For all GPU's with a compute capability >=3.0 and <6.0 there is a restriction of the amount of RAM that can be used for the mining algorithm. The maximum RAM that can be used must be less than 2GB (e.g. GTX TITAN) or 1GB (e.g. GTX 750-TI). The amount of RAM used for mining can be changed with --launch=TxB.

  • T = threads used
  • B = CUDA blocks started (must be a multiple of the multiprocessors M on the GPU)

For the 2GB limit the equations must be full filled: T * B * 2 <= 2000 and B mod M == 0. The GTX Titan X has 24 multiprocessors M, this means a valid and good starting configuration is --launch=16x48 and full fill all restrictions 16 * 48 * 2 = 1536 and 48 mod 24 = 0.

Pascal GPU's should have no memory limit if the newest CUDA driver is used.


By default xmrMiner will donate 2% of the shares to my Monero address. If you want to change that, use the runtime option --donate to de/increase the donation. If you find this tool useful and like to support its continued development, then consider a donation. Do not forget the original authors.
