Hi
  I have a 399 Taichi, ,and i want to add a 4 nvme PCIE card; the one i'm looking at
 
   https://www.amazon.com/KONYEAD-Expansion-Card%EF%BC%8CSupports-256Gbps%EF%BC%8CM2-Bifurcation/dp/B09XSY3JVS/ref=sr_1_4?keywords=pcie%2Bnvme%2Badapter&qid=1688822718&sr=8-4&th=1" rel="nofollow - https://www.amazon.com/KONYEAD-Expansion-Card%EF%BC%8CSupports-256Gbps%EF%BC%8CM2-Bifurcation/dp/B09XSY3JVS/ref=sr_1_4?keywords=pcie%2Bnvme%2Badapter&qid=1688822718&sr=8-4&th=1 
   has this requirement:
 
 
  The motherboard must support PCI-E split function and be able to set PCI-E X4X4X4 or 4X4 mode; the motherboard supports PCI-E RAID function (the number of PCI-E split channels varies from motherboard to motherboard, some motherboards PCI-E RAID is X8+X4+4X).
 
  but i can't find anything in the manual about all that. Anyone know or use a similar item?

Ask ASRock directly:  http://event.asrock.com/tsd.asp" rel="nofollow - http://event.asrock.com/tsd.asp 
  I don't see why it couldn't work, X399 has more than enough PCIe lanes.
