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).
I wouldn't use the 4010/4011 ports if you're not using the v5 mainly because if whatever switching software on the client side is out of sync with the 4010/4011, you'll just be trying to mine on a dead port and it'll go to your secondary. If for instance X13 is more profitable, the 4011 port is on, but you'll see the 4010 port as dead and vice versa.
Just a note though, my miner sees the 4010 and 4011 ports both dead quite a bit, at the same time and I end up mining my secondary for a few minutes.
Sgminer v5.0 is required for using the 4010/4011 ports. One workaround for having both ports dead is put one of the profit switching ports as top priority and then a normal port for the other algorithm after so that the second port is always alive.
My switcher also requires sgminer v5.0 but only because it is faster when switching algorithms because it doesn't have to kill the miner and start a new one up. I may at some point in the future add the ability to have separate miners per algorithm to support non-v5.0 versions.
With the new updates to sgminer v5.0 there should be improvements for the hash rate using AMD driver 14.6 so it should be comparable to the other faster miner I believe (I haven't updated since the 6/6/2014 build yet though so I'm not absolutely certain).
