    Its the cpu, not the motherboard. If you want a budget NVME system consider using and old xeon v2 system. I can suggest one of the Chinese x79 boards. You can fit 2*hyperX cards. I think the Antermiter x79 turbo could work for you. Another option is to use an x8x8 bifurcation Card and then two...

    Only the asrock x99 and asrock x299, as well as their asrockrack counterparts. Intel mainstream CPUs don't support x4x4x4x4 at all.

    Yes your understanding is correct. The latest intel mainstream even only supports x8x8. The Gigabyte aurus x570 does support x4x4x4x4 though. Also check the asrock rack x570 as it also boasts 2* oculink 4i for even more storage. the craziest option would be the asrockrack deep itx...

    malexejev 1. option one has no clock distribution. Drives AND Mainboard/CPU must support SRIS. (seperate reference independet spread) clocking architecture. 2. This one has most likely a gen3 clock buffer on board. Both cards may or may not work in gen4 mode. That depends on too many things...

    This is of course provided your bios exposes the options.

    When using gen3/2 devices you are good. Ryzen has 24 lanes. (4 chipset, 4 M.2, 16 for slot1/2) When you use only slot 1 you can use x16, x8x8, x8x4x4 or x4x4x4x4 in slot 1. When you use slot 1 and 2 you can use x8 or x4x4 in both of them.

    Note that on Ryzen two x16 slots.means that they are already split into x8. can't do x8x8 then of course, only x4x4. Bifurcation cards and risers in combo are good for gen3. gen4 poses significant challenges regarding signal integrity. Careful consideration neccesary when planning a gen4 build.

    Impressive work with the cable. I would have lost all patience soldering it. Looks pretty decent quality too, one can see some experience there.

    Nice work. Without special tooling, wow. Which cable are you using? PTH is of course bad for anything aiming at gen4.

    this becomes especially problematic with gen4 Even that is too much attenuation for PCIe gen4. (your 3080) Try forcing link speed to gen3 in BIOS.

    Neither ribbon cable or 2-layer sound great. Mind the differential Impedance!
