After finding out that ccminer-alexis-hsr doesn't support >10 GPUs I'm trying to switch over to ccminer 2.2.3 tpruvot which does.

The problem is the hashing rate on X17 is 21% less on ccminer 2.2.3

Any recommendations?  Both tests done using same cards on the same rig with -i 20.

This image shows the screenshot of alexis-hsr vs tpruvot 2.2.3, there is a significant difference.
