Title: my MOBO GB Z270M-D3H screen goes blank when i connect a RX580 8G GPU
Post by: atstech on September 07, 2019, 10:01:31 am

@All
I am looking for a way to make my motherboard work with my Saphire Radeon RX580 8GB,  my MOBO is Z270M-D3H with 8gb kingston hyperx,
The problem is when i connect my rx580 and switch on the computer, nothing is displayed on the screen not even POST,
the screen is blank and the system doesn't boot at all,
I have to disconnect the rx580, and connect the VGA to inboard display adaptor and restart the system, and then it works,
can anyone tell me how to succesfully connect the graphics card!
wbr
atstech.

Greetings,
Have to ask since you didn't say.  The card requires an 8-pin PCIe power connection.  Did you connect this?

What power supply are you using?   

What BIOS Rev are you running?

Are there any BIOS specific updates from Sapphire for you card?

Checked all the above everything connected and rx580 supported bios in motherboard, the only problem is I need the settings in bios for me to connect the rx580 8gb and get display.

By default the first Pcie is set to boot first. Unless you have made it to boot to the IGFX first. This is on page 30 of your manual.

2-5 Peripherals

Initial Display Output
Specifies the first initiation of the monitor display from the installed PCI Express graphics card or the onboard
graphics.

IGFX Sets the onboard graphics as the first display.
PCIe 1 Slot Sets the graphics card on the PCIEX16 slot as the first display. (Default)
PCIe 2 Slot Sets the graphics card on the PCIEX4 slot as the first display
