Config file

In addition to the above command line options, there is a miner.conf file which has the exact same options. If you uncomment any config option, it will be used as the default value for that option in the next run. Config options can still be overridden by command line options.

Requirements

If you are using Windows, the minimum virtual memory must be set to the total amount of allocated gpu memory. So if you have 6 x 1080 tis and want to use 8GB on each card, you will need 48 GB of virtual memory. This only applies to Windows.

If you are running the noncerpro.exe file directly, make sure you have set UV_THREADPOOL_SIZE to atleast 32;

Usage

Download the binary packge for Windows/Linux, edit mine.bat/mine.sh file and insert your own wallet address and run it.

You can control the amount of memory allocation per thread by using --batchsize option. Here is how it works:

Allocated memory per thread = batchsize * 100 * 512 KB. For example batchsize 81 will try to allocate about 4 GB of memory.

Notice that this allocation is per thread, so if you have more than one thread you must adjust the batchsize accordingly.

Best settings

From version 2.0.0, efficient multiple threads on a single device is supported via --threads option. Usually the best performance is with --threads=2. Sample for rx 580 on linux:

--threads=2 --batchsize=80 core state:p3, core clock:1090, mem clock 2200, amdmemtweak: --ref=30(Linux) 242 kh/s

Overclocking

Argon2d is highly dependent on memory bandwidth and memory clock. Try settings the memory clock as high as possible. Other parameters must be adjusted based on the specific card and OS.

HiveOS

This is how Flight Sheet must be set: HiveOS

Dev fee

This miner has a fixed 2% dev fee. That means 2 minutes in every 100 minutes, miner will run with the donation wallet address.

V1.0.1 and prior versions had 1% fee.

Happy mining!

You can’t perform that action at this time.
