Disabling Ryzen 5 2400G Graphics in BIOS X570M Pro

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi.  I am using a ASRocks X570M Pro4 motherboard with Ryzen 5 2400G APU.  I am trying to use a EVGA NVIDIA 1070 graphics card.  I have a 600 watt EVGA power supply.  I ran DDU to uninstall all drivers and installed NVIDIA drivers.  I am connected to the Display Port and HDMI from the graphics card.  My screens black out after a few minutes.

Do I need to go into BIOS and disable the APU?  If so how is that done?

Thank you!

	So you do get display on the 1070 but it cuts out? You will need to look through the BIOS settings, the setting to disable it is sometimes moved from one section to another so the manual isn't always accurate. It is a good starting point for where to look however. You can download your manual in PDF format from your motherboard's product page.

	I have output from the 1070 and it cuts out. I think there are a few settings in the BIOS for the APU. Does anyone know what the settings should be set to? Thank you

	I believe the settings you are looking for should be under Advanced > AMD CBS > NBIO Common Options > GFX Configuration As for what to set them to, I am afraid I can't help you as they are grayed out on my 3600 system. It should be fairly self explanatory however.

	I entered the BIOS and I could not find a "GFX CONFIGURATION". I am trying to disable my APU graphics, what do you recommend? Screenshot https://share.icloud.com/photos/0f00HmApAop59cOBRlar8SyYg
