Tualua commented Dec 1, 2019

Hello!

My rig is 2xE5-2660v2 and 2x4GB RAM and xmr-stak-rx 1.0.1, Ubuntu 16.04

If I manually run xmr-stak-rx with testing it starts with 26 threads and hashrate is 2.2kH/s

If I close miner and restart it without pointing it to newly generated cpu.txt it starts same 26 threads but hashrate is only 1.2kH/s

So my question is how do I properly configure it?

How it looks with fresh start without cpu.txt

bug should be fixed with #2590, even for the first start the miner was not working correct.

It works. Thank you.

Also a question about CPU autoconfig. Why xmr-stak thinks that best number of threads is number of physical cores+3? On randomX for 2660v2 my best result is num of threads = num of physical cores.
