Hello! Today’s PCIE lane video came up really relevant, since I’m currently troubleshooting some problems and thought I’d ask for advice from those familiar with the intricacies of PCIE. Background: I started assembling parts I already had and ended up building an Unraid server while merging several DAS into a solid NAS setup. This expanded to hosting my Plex server and running an emulation VM. Setup: An AMD 7950X3D from ASUS Prime B650M-A, paired with a 2TB SSD (32x2 DDR5 12SATA at 64GB), plus a 6-plug expansion card connected directly to the board. I’m using a Quadro P2000 for Plex/Dockers, a PCIEx4 6-Port SATA 3.0 card, and a 10G Nic 3090 for the emulation VM. This will soon be swapped for a 3060 or 4060, though I’ve had the 3090 around so I’m testing it now. Currently only a few SATA drives are recognized—likely due to PCIE constraints. The 3090 isn’t detected in its original port but works fine in the top port with a rise voltage setting. I keep it in the bottom slot for full access across all four bays; the riser is proving difficult to configure inside the rack chassis. My main concerns: Can this configuration function with this board? Even if that means considering an x1 10G Nic instead of the x4, or skipping the Nic altogether and using the built-in 2.5G? What’s the optimal arrangement for placing the drives without a riser? Would upgrading to another motherboard make this work without major changes? If so, which models are recommended (ATX/MATX/ITX compatible)? Thanks to anyone who helped through my detailed post!
I might have forgotten to include an identifier; this is the board.
The standard setup for this board (using your CPU) is as follows: Slot 1 holds a PCIe x16 4.0 port, Slot 2 has a PCIe x1 4.0 port, Slot 3 another PCIe x1 4.0 port, and Slot 4 also a PCIe x1 4.0 port. This indicates that cards with interfaces larger than x1 can only operate at maximum speed in slot 1.
It seems a fresh board would be a reasonable choice, isn't it? A Strix X670E-E fits well, though it has only three slots. Dropping the 10G Nic might also be viable.
This setup would work better, correct. The configuration details are as follows:
- Slot 1: PCIe x16
- Slot 2: Disabled
- Slot 3: PCIe x4 M.2_3 disabled
- Slot 1: PCIe x8
- Slot 2: PCIe x4
- Slot 3: PCIe x4 M.2_3 or disabled
