I'm having a similar issue. My configuration is as follows:

PCIE1: Network card
PCIE2: GPU
PCIE4: HBA

M.2_1: nvme drive
M.2_2: nvme drive
M.2_3: nvme drive

Everything work flawlessly until I install the GPU. Once the GPU is installed, the HBA gets disabled. The manual says that the configuration above should run at x8/x8 but it doesn't seem to. It also says that the M.2 slots do not share lanes with the PCIE slots.

Is there a way to manually set the PCIE slots to 8 lanes?
Any other ideas why this configuration would not be working?

P.S. I have tried all the usuals, multiple HBA cards, multiple GPUs, swapping slots, swaping PSUs, etc. ]]> Wed, 13 Mar 2024 19:00:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=19591&PID=114716&title=z390-taichi-pcie-lanes#114716 https://forum.asrock.com/forum_posts.asp?TID=19591&PID=90439&title=z390-taichi-pcie-lanes#90439 Author: ASRock_TSD

Hi Animalm4st3r,

Thank you for your post.

In general, the M.2/SATA storage you connected to Z390 Taichi will not affect the PCIe Lanes of your GPU.

We recommend following the below setup to install your device.

PCIE2: GPU
M.2_1: nvme drive
M.2_2: nvme drive
SATA3_2, SATA3_4~5: SATA devices
SATA3_A1~A2: SATA devices

All the best

Okay AsRock help me out here.

You dont have a chipset for NVME and use the CPU PCI-E Lanes for the NVME drives.

Right now im using 2 NVME Drives and 5 SATA Storage drives.

So why is my GPU only running on 4 Lanes and not 8 when Intels specsheet states it should split the lanes as follows

1x16 or 2x8 or 1x8+2x4]]> Mon, 20 Sep 2021 04:24:46 +0000 https://forum.asrock.com/forum_posts.asp?TID=19591&PID=90300&title=z390-taichi-pcie-lanes#90300
