Hello. I have Asus Z87-Pro motherboard with last bios version and 4xR9 290 Sapphire. All working fine but I have one little problem. If computer restarts mobo stack on B2 Error. I getting this error only if no monitor connected to GPU. I could not find working DVI-D-VGA adaptor now. I turn on onboard Intel adaptor and insert to it dummy plug. Now computer restart without any problem. But now when cgminer starts I get this :

I use cgminer –n and found what R9 290 is device 0,1,2,3 on platform 0. Intel VGA device 0 on platform 1. I add in cgminer bat file this :
--platform 0 –d 0,1,2,3
But still getting error about ADL found less devices than opencl.
Cgminer working but I can’t monitor GPU temp and fan speed. If i attach monitor to R9 290 cgminer starts without this error. I have 14 rigs and i don't want buy 14 monitors.
What I doing wrong ?
