[wangine]

Hello everyone , a good friend from another side of the world send me here. I have a asus z10pe-d8 ws motherboard , 128Gb ECC RAM, 2x intel Xeon E5-2690 v3 . video RTX4090 . The4 bios is the last asus site update.
The board work fine with the onboard M.2 .
I have 4 NVMe and i buy two adaptors for PCI to NVMe  , 4 slots . No one works , last one is asus Hyper M.2 x16 card gen 4 . If i let only one m.2 , works , if i change slot become corrupted . With two M.2 on that card , the PC enter in conflict with video card (video editing become 10 time slower) and no any M.2 work also. I search everywhere , some one can help me ? People said to me need a bifurcation mod on bios.
Thank you
