Firstly, thank you all for your help so far (messages and so on)

My rig - now 4 weeks old, ALL new kit.

Tried 11.2 today and apart from virus guards kicking off all over the place (until I disabled them all) failed to work.

I have now kind of got the rig working thanks to some help, however...

Starts at 64 Mh/s then reduces down and down...
