Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v11.7 (Windows/Linux)

original Bitcointalk theme with Download


This version is POOL/SOLO for Ethereum, POOL for Decred, POOL/SOLO for Siacoin, POOL for Lbry, POOL for Pascal, POOL for Blake2s, POOL for Keccak.


For old AMD cards, Catalyst (Crimson) 15.12 is required for best performance and compatibility.

For AMD 4xx/5xx cards (Polaris) you can use any recent drivers.

For AMD cards, set the following environment variables, especially if you have 2GB cards:


GPU_FORCE_64BIT_PTR 0

GPU_MAX_HEAP_SIZE 100

GPU_USE_SYNC_OBJECTS 1

GPU_MAX_ALLOC_PERCENT 100

GPU_SINGLE_ALLOC_PERCENT 100


For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB (better more):

"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".


This miner is free-to-use, however, current developer fee is 1% for Ethereum-only mining mode (-mode 1) and 1.5% for dual mining mode (-mode 0), every hour the miner mines for 36 or 54 seconds for developer.

For all 2GB cards and 3GB cards in Windows10 (they cannot mine ETH/ETC anymore) devfee is 0%, so on these cards you can mine all ETH forks without devfee, this miner is completely free in this case.

If some cards are 2GB and some >2GB, 2GB cards still mine for you during devfee time, only cards that have more than 2GB memory will be used for devfee mining. Same for 3GB cards in Windows10. Miner displays appropriate messages during startup.

Second coin (Decred/Siacoin/Lbry/Pascal/Blake2s/Keccak) is mined without developer fee.

So the developer fee is 0...1.5%, if you don't agree with the dev fee - don't use this miner, or use "-nofee" option.

Attempts to cheat and remove dev fee will cause a bit slower mining speed (same as "-nofee 1") though miner will show same hashrate.

Miner cannot just stop if cheat is detected because creators of cheats would know that the cheat does not work and they would find new tricks. If miner does not show any errors or slowdowns, they are happy.

This version is for recent AMD videocards only: 7xxx, 2xx and 3xx, 2GB or more. Recent nVidia videocards are supported as well.

There are builds for Windows x64 and for Linux x64 (tested on Ubuntu 14.04). No 32-bit support.
