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!

i don't think you have much options. cheapest = use gpu in x8. you could try an adapter to plug the ssd into sata port, but no idea if that would even work. just for the fun of it, i looked at my 7800x3d specs and under connectivity it states that 24 pcie lanes are usable of a total of 28, but mobo provides an additional 8 or 16 more depending on the chipset. wondering if that results in 32 or is it limited to 28...
