Hi everyone, it worked for me HackFlags. My mining is running 5 gpu perfectly. Here's my setup:
Asrock H81 Pro Btc R2.0
Celeron G1840
5 Gpu Gtx 1060 3gb
4gb ddr3
Windows 7 Ultimate SP1 64bit

 I did not need to update the bios, just install the drivers with nvidia 382.53. Important, connected with the video onboard, and disabled on the audio bios onboard and disabled in the device manager all the audios of the gpu.
