PCIe bifurcation
PCIe bifurcation
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!

If you got something like the ASUS Hyper M.2 x16 Gen 4 Card:

https://www.asus.com/us/motherboards-components/motherboards/accessories/hyper-m-2-x16-gen-4-card/
Then there are specific motherboards listed that support the bifurcation requirements.
Of course, if your x16 slot is taken up with this thing, you can no longer use the slot for a graphics card.
Perhaps the cheapest way forward would be to use your x16 slot for graphics, and distribute your 4 M.2 cards using multiple adapters in the smaller slots (if you have room for that). One of the adapters might need to be PCIe x1. Well, cheaper than Threadripper!
That's precisely the SSD PCIe solution that I bought. ^^ Yeah, might have to redistribute... Thanks for letting me know about the compatibility listing, I wasn't aware of it. I'll check if I can get one of those second hand.
Edit: I'm slightly worried about ASUS as a mainboard supplier though because of their recent rootkit escapades...
