Hi. I have the Z370 A Pro and I am trying to have three UAD dsp cards in it. But I manage to only use 2. I wonder if there are any tricks to make it work with 3, or if there are some limitations? I only have a network card in addition. I had some changes done to the system, installed an xtra M.2 disk, I have two now. The network card didn't work on the slot it used to work in, so I had to move to another slot. So now, whatever I do, the board only finds two cards and the network card. (I use the onboard graphic card) That leaves 3 slot unused.

Any suggestions?

You have to make the newest BIOS work, because there's a chance that your problems with the slots were solved in a BIOS update. They always fix more stuff than what is listed in the BIOS changelogs.

In the BIOS, can you tell me what BIOS mode is active (it's written in the top middle section), UEFI or Legacy? If it's Legacy, that's where the problem with the new BIOS comes from, because it will default to UEFI mode. If your Windows was installed with the BIOS in Legacy mode, it will not boot with the BIOS in UEFI mode unless you reinstall Windows or convert the boot disk from MBR to GPT.

Thought so. Yeah, once Windows is installed, it will only boot with the BIOS mode that was active during installation. Legacy mode is outdated, it was only needed for Windows 7, but for anything after that, UEFI mode is better, and Windows 11 will actually require UEFI mode. Either you do a fresh install in UEFI mode (create a USB installation stick using the latest Media Creation Tool, in the tool, select "Create installation media (USB Flash drive)", then boot from the stick by pressing F11 during boot for the boot menu and select the stick there).

The other option is to convert MBR to GPT, https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt
There's other tutorials you can find on that procedure as well.

I'm afraid that without any of this, you might not be able to solve your slot problem.
