How do I boot the computer without a GPU?

I need a computer to boot, I am not interested in what it would like to display on a monitor, which won't be attached. Which motherboards support this? I would prefer not to waste a PCIe slot on useless graphics. Is there a trick which would allow it? Are there reasonably cheap consumer oriented motherboards that would allow it? Would be great if they supported ECC RAM on Ryzen processors too ūüôā
I have bought some $5 graphics card (Radeon 4350) which allows the computer to start, but I would like to use that PCIEx1 slot for other purposes.

Consumer mobos don't boot without a graphics adapter. Either get a mobo and CPU with integrated graphics or start looking at server hardware.

In general I noticed that, but are there no exceptions?

IPMI could allow this, but it'd be a motherboard thing. Usually found on server motherboards so they can be ran headless. @Electronics Wizardymight be able to help here more since it sounds like you're thinking server route with ECC anyways.

I'm not actually trying to be as grumpy as it seems.

Why is the 5800x so hot?

Actually I have constructed a mini-PC from old Asus B450M-A II motherboard I had in the box. It booted without video card.  Gigabyte's mobo doesn't boot. I am pretty sure Asus B450M-A  (first edition) doesn't boot.

What CPU are you using?

Did it boot and output video? 

Regardless, this looks close to what you want.

Doesn't officially support Zen+, but apparently does and IPMI. Supports ECC as well.

It did boot, did not output video. Access the computer via the ethernet and/or serial port.

The serial port access is actually pretty cool, as the cable length may be pretty impressive, which is difficult/expensive to achieve with HDMI. It also works from very early stages of OS boot, so if network fails to work for some stupid reason, the serial port is there.¬† The motivation is actually to replace a graphic card with 10G lan, when I manage to buy a good cheap used 10G card ūüôā


I will investigate this IMPI. At first glance sounds very useful. Thanks!
