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!
as x4/x4, but PLX would divvy it all up essentially 4x M.2 at x2/x2/x2/x2, that kinda thing. If this adapter doesn’t have it and you can’t get this to work, and you’re willing to blow another hundred bucks, that other kind of adapter would def work.
Without knowing your motherboard I’d def download the manual and ctrl+f some promising keywords such as ‘bifurcation’ or ‘PCI’ and basically hunt for anything in the manual that describes settings to enable this. Sometimes on a 3 slot board the bottom ‘chipset’ slot can be toggled to run something different than PCH, like some other controller.
I’d also try running the adapter in every possible configuration, on the most current supported PCI-E standards and a previous generation if motherboard allows, ie: adapter top slot, GPU middle slot, GPU top slot, adapter 3rd slot (if mobo has one), disable PCI-E 4.0 or enable 3.0 each time just to see if some configuration works (kinda tedious but costs 0 dollars so
Thanks for the hints. I’ll try to put it in gen 3.0 mode and see if I get more settings there, good idea!
