I recently bought an LSI 9207-8i, and when trying to install it onto my server I discovered the whole machine won't boot with the card installed. I'm running 7.0 on a an AMD 9900x. My MSI mobo has an up to date bios, and the LSI card works when plugged into my windows machine and shows as in IT mode with version 20.00.06 firmware on it. The system not only won't boot, but won't let me into the bios with the card installed, and instead just boot loops. I get a flashing green light on the LSI card, and the first couple boots I see the VRAM light on the mobo flash, but eventually that light stops flashing as it continues looping. Anyone have any thoughts on this? I'm starting to get the feeling the card is bad or a fake, and I might just return it to buy one for The Art of Server instead.

Mobo: MSI Pro X870-P

That appears to be an LSI clone, may still be worth trying this:

Thanks @JorgeB! I did forget to mention that I had found a similar thread and did try the tape trick to no avail as well. The card has the LSI branding and the darker/glossy pcb (Not shown in the listing pictures) so I thought it might be real, but at this rate of a few days frustration I think I'll return it and buy from The Art of Server. Thanks again!!

Well here I am again with a 9207-8i from The Art of Server, and I'm hitting the same wall again. I get a solid orange dram light when the system tries to boot with the card installed. Any other thoughts out there?

This usually means a board issue, but if the tape trick didn't help, don't know what will, recommend trying a different model, like a 9300-8i

What slot are you using? Only the E4 slot is usable (near the edge of the board) since that's x4 (which should run the card, but I haven't tested that model on x4), the others (E2 and E3) are x1 and most likely won't work. (Also assuming E1 is in use for the graphics card). If you have an SSD in the slot next to it, it'll only run at x2 which also may not be compatible.
