Miner programs are often flagged as malware by antivirus programs. This is
|
|
a false positive, they are flagged simply because they are cryptocurrency
|
|
miners. The source code is open for anyone to inspect. If you don't trust
|
|
the software, don't use it.
|
|
|
|
Choose the exe that best matches you CPU's features or use trial and
|
|
error to find the fastest one that works. Pay attention to
|
|
the features listed at cpuminer startup to ensure you are mining at
|
|
optimum speed using the best available features.
|
|
|
|
Architecture names and compile options used are only provided for
|
|
mainstream desktop CPUs. Budget CPUs like Pentium and Celeron are often
|
|
missing some features. Check your CPU.
|
|
|
|
Support for AMD CPUs older than Ryzen is incomplete and without specific
|
|
recommendations. Find the best fit. CPUs older than Piledriver, including
|
|
Athlon x2 and Phenom II x4, are not supported by cpuminer-opt due to an
|
|
incompatible implementation of SSE2 on these CPUs.
|
|
|
|
More information for Intel and AMD CPU architectures and their features
|
|
can be found on Wikipedia.

* Alderlake is a hybrid architecture with a mix of E-cores & P-cores. Although
|
|
the P-cores can support AVX512 the E-cores can't so Intel decided to disable
|
|
AVX512 on the the P-cores.

Notes about included DLL files:
|
|
|
|
Downloading DLL files from alternative sources presents an inherent
|
|
security risk if their source is unknown. All DLL files included have
|
|
been copied from the Ubuntu-20.04 installation or compiled by me from
|
|
source code obtained from the author's official repository. The exact
|
|
procedure is documented in the build instructions for Windows:
|
|
https://github.com/JayDDee/cpuminer-opt/wiki/Compiling-from-source
|
|
|
|
Some included DLL files may already be installed on the system by Windows or
|
|
third party packages. They often will work and may be used instead of the
|
|
included version of the files.
