The Micronik Z3 board needs an A3000/A4000 accelerator to work properly. You might get it going if you force the busboard into Z2 mode - there's a jumper that does that.
Also, are you powering the board correctly? Power should go through the busboard. You'll need an adaptor to get the PSU's standard AT P8/P9 plugs connected to Micronik's custom power connector. Elbox sells them.
