Just because no one has mentioned and "not mentioned" it: did those cards work with or without separate PCIE-power supply, i.e. does the board features PEG slots (delivering up to 65W) or does the board is limited to PCI (delivering up to 25W max!)?

Oh fun fact, after lots of trouble shooting and bisecting the issue with beta BIOSes:

Code:
Please be informed that after all those tests our TWN BIOS team found out that your problem is due to your specific hardware configuration and security patch(Stage 4).

In this case it means that to provide you a definitive solution you will have to use an OEM bios specifically made for your case; to do so you will have to contact your supplier that must contact his Supermicro sales representative for this OEM bios request.

Please note that OEM bios will have a charge fees.
lmao "Our BIOS is broken and has a regression, please pay for a custom BIOS thanks"

I wonder if that's the rationale behind the v.1 Gtx1030 cards? I've snapped a few of those up because they only draw 20W and they work in the most limited of builds. GeForce GT 1030 | Specifications | GeForce

Successfully installed a Radeon RX 5700 XT on a Supermicro H12SSL-i with BIOS 2.5. No special BIOS configuration required except one:
Onboard Video Option ROM Enable (DISABLED).

The BIOS at first displayed an UNKNOWN DEVICE in the Advanced > AMI Graphic Output Protocol Policy and I changed the Bifurcation setting for the GPU SLOT from AUTO to X16 thinking that maybe the motherboard just doesn't know how to deal with the card. After the BIOS had recognised the GPU I lchanged the setting back to AUTO. Not sure if forcing the SLOT to X16 enabled the motherboard to properly detect the card.

The AMI Graphic Output Protocol Policy now displays:
NAVI10
AMD GOP X64 Release Dri
Output Select DFP3_HDMI

Some more about dealing with GPUs on Wendell's Level1Techs video on the H12SSL varients:
If you are installing Windows he recommends using a JUMPER to disable the Onboard VGA.

Even with the iKVM video output disabled in BIOS the booted Linux Live Installer will list the iKVM display in the iSpeed controller as a Virtual Monitor in the Linux Display Configuration panel. The mouse on the PC remotely connected to the Supermicro iKVM/BMC can be used to drive the cursor on your Supermicro workstation's main display. Linux automatically bridges the two video hardware systems. The iKVM Virtual Monitor can be disabled in the Linux Display Configuration panel.

To me it seems that most cards should work on the H12SSL series, BIOS versions notwithstanding.
