Claymore ZCash Miner

Claymore’s ZCash/BTG GPU Miner v12.6

This version is for pools.

Catalyst (Crimson) 15.12 is required for best performance and compatibility.
15.12 does not support some Fiji cards, use 16.3.2 for them.
For 4xx cards (Polaris) Crimson 16.12.2 is recommended.
NOTE: For best performance on Fiji cards you must use 15.12 or 16.3.2 drivers. For newest drivers speed will be slower!
You can get bad results for non-recommended drivers, or miner can fail on startup.
Set the following environment variables, especially if you have 1-2GB cards:


For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:
“Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory”.

This miner is free-to-use, however, current developer fee is 2% if you use secure SSL/TLS connection to mining pool, every hour the miner mines for 72 seconds for developer.
If you use unsecure connection to mining pool, current developer fee is 2.5%, every hour the miner mines for 90 seconds for developer.
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, 3xx and 4xx, 1GB or more.

There are builds for Windows x64 and Linux x64. No 32-bit support. No NVidia support.
