PCIe bifurcation (lemy.lol)

Hey y'all, I bought a x4x4x4x4 4 slots M.2 PCIe card foolishly thinking that if it fits in the slot, it would surely work. In the end, I got 2 of the 4 SSDs working on my old AM4 X470 chipset. I'm coming to you for advice what the cheapest way to get to use this would be. I've noticed that a lot of CPUs have a PCIe lane limitation of 28, just short of what I need (I'd like to run the SSDs but also a x16 GPU). I'm not too keen to buy a threadripper setup for this occasion...

Cheers!

What’s the motherboard model? Which slot are you attempting to use? Is it a physical X16 slot with only a X8 connection? Do you have any other slots available for M.2 drives?

It's a MSI X470 GAMING PRO. Tried both upper x16 slots. The second one seems to be x8, but the first one doesn't work either despite being x16. I have other m.2 slots but they're already used up - however those are smaller SSDs so worst case I could move my OS to a SATA drive and populate those m.2 slots with the larger and newer SSDs that i bought! 😂
