Thanks langes01x.
Just one point that I didn't get 100%: do I need sgminer v5.0 to use the 4010/4011 ports on TMB?
Ideally I'd be using the TMB autoswitcher as x11mod/x13mod give quite a boost compared to dark/maru... and I'm using PIMP on my mining rig (not too keen on having my PC running 24/7 just to be able to steer & monitor it).
