Frequently Asked Questions¶
Why does Bminer use a significant amount of CPU cycles?¶
Bminer can poll the GPUs to get the results of mining faster at the cost of higher CPU usages. Alternatively you can configure Bminer to sleep and wait instead of polling the GPUs by appending
-polling=false in the command line, however it might reduce the performances in some configurations.
Bminer fails to start because
nvml.dll was not found. Where can I find it?¶
Bminer uses the NVIDIA Management Library (NVML) to monitor the health of the GPUs. The NVML library is shipped with the NVIDIA driver and commonly you can find it at
C:\Program Files\NVIDIA Corporation\NVSMI.
Why does Windows Defender report Bminer as virus / malicious software?¶
Bminer uses DRM techniques to prevent itself to be tampered. Anti-virus softwares sometimes classify them as viruses because the techniques are used to obfuscate malicious software.
Bminer is not a piece of malicious software. You do have to add an exception in Windows Defender to use it. However, we strongly recommend to check the hash signatures when you download the releases to ensure the software has not been tampered.
Bminer crashed and it cannot be restarted until rebooting the machine.¶
The problem happens more often when there are hardware failures (e.g., loose cables, insufficient powers) during mining. It can be difficult for operating systems and drivers to recover from these cases. Therefore you will have to reboot the system or even press the Reset button instead of just restarting Bminer.
Why does BMiner take so long to get up to speed?¶
Bminer reports Exponentially Weighted Moving Average of the speed and takes the last couple minutes of the speed into account.
While the number of speed shown by bminer for the first few minutes is smaller, there is no differences on actual speed. The reported speed will converge to the real speed in several minutes.
