FAQ

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.

You have to upgrade your Nvidia drivers. Install cuda 10.2.

Why windows defender delete exe file?
The exe of a miner is recognized by antiviruses as a virus, for normal operation add the folder with the miner to the antivirus exceptions.
