so just in case someone is interested, I use the following parameters:

intensity: 118 (120 gives 1880 h/s, but I do not risk to give it a long try as I am far away from my rig atm).

double threads: true


concerning the vegas themselves, I have Nitro+ 56, parameters via OverdriveNTool

1590 - 1000
930 - 950
