(ANN)KawPowMiner v1.2.2 - first miner for KawPow algo [AMD/Nvidia]


About miner:
KawPowMiner is an ProgPoW GPU mining worker, with KawPowMiner you can mine Ravencoin, which relies on an ProgPoW-based Proof of Work thus including Ethereum ProgPoW and others. This is the actively maintained version of kawpowminer.


Features:

-First KawPow miner software for miners.
-OpenCL mining
-Nvidia CUDA mining
-Realistic benchmarking against arbitrary epoch/DAG/blocknumber
-On-GPU DAG generation (no more DAG files on disk)
-Stratum mining without proxy
-OpenCL devices picking
-Farm failover (getwork + stratum)
-Ethereum-based ProgPoW implementations supported only, doesn't support previous ethash version or Bitcoin-based forks.
-Dev fee 0%

Why is my hashrate with Nvidia cards on Windows 10 so low?
The new WDDM 2.x driver on Windows 10 uses a different way of addressing the GPU. This is good for a lot of things, but not for ETH mining.

-For Kepler GPUs: I actually don't know. Please let me know what works best for good old Kepler.
-For Maxwell 1 GPUs: Unfortunately the issue is a bit more serious on the GTX750Ti, already causing suboptimal performance on Win7 and Linux. Apparently about 4MH/s can still be reached on Linux, which, depending on ETH price, could still be profitable, considering the relatively low power draw.
-For Maxwell 2 GPUs: There is a way of mining ETH at Win7/8/Linux speeds on Win10, by downgrading the GPU driver to a Win7 one (350.12 recommended) and using a build that was created using CUDA 6.5.
-For Pascal GPUs: You have to use the latest WDDM 2.1 compatible drivers in combination with Windows 10 Anniversary edition in order to get the full potential of your Pascal GPU.

Why is a GTX 1080 slower than a GTX 1070?
Because of the GDDR5X memory, which can't be fully utilized for ETH mining (yet).

Are AMD cards also affected by slowdowns with increasing DAG size?
Only GCN 1.0 GPUs (78x0, 79x0, 270, 280), but in a different way. You'll see that on each new epoch (30K blocks), the hashrate will go down a little bit.

Can I still mine ETH with my 2GB GPU?
Not really, your VRAM must be above the DAG size (Currently about 2.15 GB.) to get best performance. Without it severe hash loss will occur.

What are the optimal launch parameters?
The default parameters are fine in most scenario's (CUDA). For OpenCL it varies a bit more. Just play around with the numbers and use powers of 2. GPU's like powers of 2.

What does the --cuda-parallel-hash flag do?
These improvements were optimised for GTX 1060 GPUs which saw a large increase in hashrate, GTX 1070 and GTX 1080/Ti GPUs saw some, but less, improvement. The default value is 4 (which does not need to be set with the flag) and in most cases this will provide the best performance.

Can I CPU Mine?
No, use geth, the go program made for ethereum by ethereum.
