best rig at 119H/s is the asus z170a using an i5 6500t
worst rig at 108H/s is the biostar z170a using an i3 6300t
the asrock h81 is at 113 H/s using an intel i5 4570s
the asrockz170 extreme 3 is at 115 H/s using an i7 6700t
What does it all mean? I suspect to run at -i 2 you need an i5 .
I also have virtual memory set at 32000-64000 on all rigs.
Very odd results given that the i7 6700t is near-identical clocks to the i5-6500t and has a LOT bigger on-chip cache, so should be punching out it's processing faster.
Probably other factors at work too - have you considered swapping parts around in testing?
