Hello everyone, I have an intel S2600WTT server board with 2x XEON E5-2699 v3, 1x Intel A2UL8RISER2 Riser Card, and two sata hdd's. Here is my issue, I just recently purchased an ASUS Hyper M.2 x16 PCIe 3.0 x4 Expansion Card and have installed 1X SABRENT 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 and 1x SABRENT 500GB Rocket Nvme PCIe 4.0 M.2. The ASUS Hyper is installed into the 1st slot (top) on the riser card in Slot 1 of the server board PCIE connector. The riser card has all three slots at x8 written next to each slot (with the top two using a PCIE x16 plugin, and the third is a x8 plugin). I checked ASUS's website on the quad m.2 card to see if it can be bifurcated and it looks like i can (https://www.asus.com/support/FAQ/1037507/). In the BIOS, there is a selection for PCIE bifurcation. In there, the bifurcation selections only shows up in the other PCIE server board slots that is not populated with the riser card (very frustrating) (meaning if server board slot 1 is populated, slot 2 and 3 bifurcation setting will show up.) Selections are 4x4x4x4 or 8x8 for slot 1 and 2, and 4x4 or 8 for slot 3. Of note, the ASUS card is recognized by the system and unraid, but only the 1st of the four M.2 slots is read. Do I need to get a dual or quad M.2 expansion card that is bifurcation only like this one (https://www.newegg.com/p/17Z-0061-000B2?Item=9SIARE9JVF1975) or am I screwed? or do I need to get an expansion card that is x8 and not x16? Thank you! Also, I saw the other forum with similar issues but I want to see if anyone can help from my setup.
