Hey, Just wondering if this is possible. I am running a server, for which I have a PCIe NIC and a SAS HBA card. Motherboard is MSI b450 Gaming Pro Carbon AC As it stands, if I install both PCIe cards, I lose access to the NVMe drive. Originally I had it in the M2_1 slot, but putting a card in the PCI_E1 slot disables that one automatically, so I moved it to the M2_2 slot...but adding the second card seems to have disabled that slot as well. I understand that this has to do with sharing PCIe lanes, and there are a handful of settings in the bios that seem to allow changing how the various PCIe slots behave, but I admit that this is a bit beyond my understanding. Is there a setting in the bios that I can change that will allow me to use both cards and the NVMe drive simultaneously? Or would that require a new motherboard? If so, is there an AM4 board that would support this with a Ryzen 3 3200g? Right now, that processor is sufficient for my uses, so I don't want to spend money upgrading something that still works fine. Thanks
After reviewing the instructions carefully, it seems your assessment is accurate. I’ll try it again today and observe the outcome. It might resolve, possibly just needing the drive repositioned.
