A graphics card of any kind won’t fit in the bottom PCIe slot because of all the io connectors next to it. You need a riser yo use the bottom PCIe slot.

This. I was so confused when I saw op’s post: why on earth to buy an old only 16gb vram card with the price of multiple larger vram and newer cards?

Thanks! I will search for SFTP and S3:)

It’s 20b or .2b or 200000000b doesn’t bother me at all.
