Having issues installing past 4 GPU's

[Frenchy19951]

I want to thank everybody that took the time to answer me and give out your opinions, it was greatly appreciated and it led to me fixing my rig! Following what some of you have said regarding the bios settings I found a thread online with people that had the same motherboard with the same problems. I went ahead and did what this one user suggested and updated these following settings:
updated the bios to the newest version
made the following settings to the bios:
BIOS => Advanced Mode(F7) - Advanced\System Agent (SA) Configuration\DMI/OPI Configuration - DMI Max Link Speed - Gen2
BIOS => Advanced Mode(F7) - Advanced\System Agent (SA) Configuration\PEG Porn Configuration - PCIEX16_1 Link Speed - Gen2
BIOS => Advanced Mode(F7) - Advanced\PCH Configuration\PCI Express Configuration - PCIe Speed - Gen2
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - HD Audio Configuration - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - LED Lighting - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - Charging USB devices in Power State S5 - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration\Serial Port Configuration - Serial Port 1 - Off
BIOS => Advanced Mode(F7) - Advanced\System Agent (SA) Configuration - Above 4G Decoding - Enable
BIOS => Advanced Mode(F7) - Advanced\RPM Configuration - Restore AC Power Loss - Power On

One thing I could not find was the DMI/OPI configuration. Everything else I was able to find and adjusted it. Right now my rig is mining and running perfectly!
Thank you everybody!

I keep going in circles over this. I feel like I have all of these settings but these 4:

BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - HD Audio Configuration - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - LED Lighting - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration - Charging USB devices in Power State S5 - Disabled
BIOS => Advanced Mode(F7) - Advanced\Onboard Device Configuration\Serial Port Configuration - Serial Port 1 - Off

Maybe, if I do these last 4 I can get Windows to stop telling me in the Device Manager that I don't have enough resources and I need to disconnect one of my GPUs, as soon as I plug in my 5th card.
