Hi All!
I just set up my first rig using four R9 290 (ASUS Brand). I'm getting 3.5MH/s average doing scrypt mining. All is good. However my rig will not boot with out a monitor attached. The hard drive doesn't even start blinking so I don't believe it gets past POST. If I plug in a monitor then it starts without issue. I'd really like to go headless though. My MB is ASRock Z87 Extreme9/ac. I tried upgrading the bios, no luck. The only setting I found in the bios was "primary video" the choices are onboard/PCIe. If I select onboard, then windows doesn't find the GPUs. If I select PCIe than it doesn't post without a display attached. Dummy plugs won't work because the R9 doesn't have RGB out. I probably need a different MB. Any other suggestions?

It looks like https://bitcointalk.org/index.php?topic=382752.msg4113297#msg4113297 you have a maximus extreme vi setup? I have the same motherboard that I'm considering RMA'ing b/c it won't detect all of the GPUs. You find a solution that works for getting them all to run *in addition* to running without plugging in monitor? I see you don't use dummy plugs. I thought that might be my problem but if dummy plugs don't even work then I surely have to RMA/get another board. Thanks for any help!
