@NiceHashsupport

Axiom Miner with Launcher Crashes, if i choose AVX
Cpuminer64_AVX.exe Works!!!

(CPU isn't capable of AVX2)

Any suggestion?

Thank you

I need help with this as well. Is there an AVX version or just AVX2?

If you have AVX or AVX2 capable CPU, you can run AVX version. If not, you cannot. Simple as that. Check list of supported CPUs (in README.txt file there is link to wiki page).

I have used that. My fx-6300 is a piledriver and supports AVX not AVX2. The 120% optimized cpuminer (AVX version) worked fine but the new one will not. Also tried it on my VPS which runs an IVY bridge processor and does the same thing. Appreciate all the work you guys are doing. If you can figure it out great if not the non-AVX is good too

We prepared various binaries here: https://github.com/nicehash/cpuminer-multi/releases/tag/v1.1-multi-bins

Let us know what works for you and what kind of speeds you get + what kind of CPU you have.

We did compile with /arch:AVX for launcher package - which means it should work for AVX CPUs, but we were not able to test (only have AVX2 CPUs).

With a couple of tweaks I managed to get 420H/s (3.5x boost) on my custom 8-way shabal miner from 120H/s with original miner.
What optimization flags are you using BTW?

Same. From 120 H/s to 420 H/s. We believe this is max possible with current architecture, and considering how hot CPUs get...

Larger CPU cache would help - this can be observed because in single thread is about 20-30% faster. My CPU does ~50 H/s in single thread, but as soon as I add more threads, this is dropped to 35 H/s.
