Hello, I own a PCIe splitter ranging from 16x to 8x4x4x (supporting an 8x PCIe and two NVMe slots). I’m having trouble getting it to function properly. After checking the BIOS, I confirmed the PCIe slot in the IIOO menu is set to 8x4x4x, but only the NIC in the 8x slot shows up. No NVMe device appears. I’m unsure what other adjustments might help. My splitter is named PH43 and I have the motherboard BIOS manual as a PDF. It seems some submenus are missing. Could someone point me to the relevant sections? Thanks for your assistance. 华南X99-QD4主板BIOS使用手册.pdf

I resolved the issue by testing each pcie device individually and restarting between them. Also, it seems my motherboard lacks the power to deliver enough current to all three devices when they're in full use.
