Hey guys so Im trying to run the miner but with every cpuminer sse aes sse42 etc etc. It crashes after a few seconds says cpuminer is not responding and closes my .bat file like it froze does anyone know what I can do to fix this?
Also I'm trying to mine using an old acer desktop with windows 10 and AMD cempron 145 processor 2.80 ghz if that info helps?
Thank you
Legacy version 3.5.9.1 May provide better performance on some algos with older CPUs that
don't have AES NI. Most users should not use it.
Your cpu doesn't support AES, so try the legacy version
Thanks for pitching in helping new users. Your close this time but not quite correct.
The legacy version doesn't help with incompatible CPUs, it just provides a little better performance on compatible non-AES CPUs.
The real problem is described in the errrata section in the OP but was not included in the README.txt included with the Windows
binary package. It will be added in the next release. Here it is:
AMD 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. Some algos may crash the miner with an invalid instruction.
Users are recommended to use an unoptimized miner such as cpuminer-multi.
Also it's a Sempron which, like Intel's Celeron, has fewer features than the high end CPUs of the same vintage.
The bottom line is the CPU is not compatible with cpuminer-opt.
