I checked their documentation carefully, and it seems this option isn’t available. I appreciate your effort, but it’s clear you’ve gone through a lot for me. Your tone was unkind and unhelpful—please let me know if there’s anything more useful I can provide. Thank you for your patience.

07-02-2019, 01:12 AM #13I'm a bit behind on the event, but I'm checking if e22big found the AMD motherboard you were seeking. I'm currently facing a similar situation with my own setup. Based on what I've learned, the only viable choice right now (besides a HEDT build) seems to be buying an adapter card that includes a built-in bifurcation controller chip. They're pricier, but they address the issue of a motherboard lacking support for bifurcation. BuildOrBuy on YouTube offers great tutorials on installing dual or quad adapters and configuring BIOS settings. He's also very helpful with HEDT-related questions.

07-02-2019, 08:41 PM #15This page covers around ten X570 motherboards featuring two NVMe drives connected via PCIe X16.
Typical boards with two PCIe slots can fit an 8x8x configuration. This setup has been standard for a long time. Listing 8x8x doesn’t necessarily mean a bifurcation is needed. A M.2 drive connects directly to the CPU, while another goes through the chipset. The remaining two slots are in the second 8x slot. Regarding SATA ports, it depends on the specific board. I’m uncertain about boards with six SATA ports, but I’m confident that every 8-port board will give up another feature—usually extra PCIe lanes or a dedicated M.2 slot.

If you're aiming for a budget-friendly option, consider the Aorus X570 Elite WiFi rev 1.x. It features one PCIe 16, one PCIe x4 (x16 physical), and one PCIe x1. The x16 port can be split into four channels, allowing you to fit an expansion card there and mount your graphics card in the second x4 slot. This is the setup I use and have tested my 1080ti frame rates; I notice a slight drop of a few frames, but that's about it. Also, you retain all SATA ports, so you can keep your two onboard M.2 drives, add four M.2 slots in the expansion card, and include six SATA drives. It could easily become a solid workstation board. You might find these boards on eBay for around $120 or less, especially if you're looking for deals. Even at that price, it's a strong build. At full cost it remains impressive. I personally enjoy it. Begin with the M.2 slots first before adding SATA. You'll also need to enable raid on the Aorus side—at least that worked for my Asus Hyper V 2. According to Asus, their board isn't officially supported. But hey, good luck with your setup!
