It seems that the increase in the number of instances to 3 in the configuration - gives a small increase compared to the 2.
I have around 4-5 sol +
I can only run it with instances of 1

Its also odd because when mining eth my GPU's hover around 70 degrees. Mining zec with this miner they only hover around 49 degrees.... I assume we are leaving alot of GPU capacity spare with this miner?
