Good job, man!

Rig with 5 x 1070 Ti (tuned with PL=120W and OC=200/1200)

Before with v0.3 (0.4 crashed my rigs sometimes):


After with v0.5 without any changings of my tuning:


From 199 sol/s to 236 sol/s.  
About 18.5 % more solutions than before.

Thank you so much for fixing the v0.4 issues.
