I'm searching for a motherboard featuring bifurcation functionality, compatible with server builds. Regarding the expansion card, it mentions GEN 3—can it function in GEN 4 settings when used with a Gen4 motherboard and Gen4 NVMe?
I personally use the Gen 4 version. Out of the three Asus TRX40 boards I've tried with the Gen 4 card, none lack bifurcation support. What are your other goals for this setup?
I think the formula and hero boards are confirmed to work, but a 2-drive setup on an 8x bifurcated 4x/4x X570 isn't the best choice if you plan to add expansion cards. I'm sure other boards in the range also support this, as I just reviewed those manual sections recently.
You're evaluating the setup for your system. It seems you're aiming for a high-performance NVMe configuration with RAID 0. Based on what you've shared, it looks like you're planning to use multiple NVMe drives in RAID 0 for maximum speed. You mentioned considering a 320GB RAM and around 3990X expansion card, which aligns with your hardware needs. The idea of using all NVMe drives in RAID 0 makes sense for performance, though it does require careful management. Regarding your questions: you can likely configure RAID 0 across the drives together, but you'll need to ensure proper controller support and firmware settings. Having separate NVMs on the card and motherboard is possible, though you'd need to verify compatibility with your system. The configuration of multiple drives in a single RAID array can be complex, so it's wise to research specific requirements for NVMe RAID 0 setups before proceeding.
Focus solely on the origin of your lanes. Avoid combining a CPU lane with a PCH lane drive. For my setup, an expansion card plus two x4 slots feeding directly from the CPU works best. Don't use the rear M.2 or the DIMM.2 card.
This feature plays a key role in why RAID 0 on many X570 boards isn't recommended. Just one slot uses dedicated CPU lanes while the other passes through the chipset.
Holy moly, DIMM expansion cards are definitely available too! For a project that doesn’t need heavy GPU usage, using just x4 or x8 lanes from the CPU should work fine. You could definitely install expansion cards in the PCIe slot 1 and the two M.2 slots—those would add about 40 lanes from the NVMES alone.
