Hello, all

Has anybody suceeded in building 8x GPU mining rig on Ubuntu or Win10 ?

I have MSI Z97 gaming 5 motherboards and they work great with 7 GPUs.
I tried this adapter http://www.ebay.com/itm/PCI-E-4X-Female-to-NGFF-M-2-M-Key-Male-Adapter-Power-Cable-with-Converter-Card-/311414541676 and this one http://www.ebay.com/itm/PCI-E-1X-Expansion-Kit-1-to-3-Port-Switch-Multiplier-HUB-Riser-Card-USB-Cable-/191949792720
Both didn't help to work 8th GPU. Though here https://www.youtube.com/watch?v=F9z5bmjEepQ&t=21s the rig is built.
Please share your expertise in this question

Thanks,
Serge
