Using a PCIe x1 card in a PCIe x16 slot

The PCIe x8 Gen3 backplane supports a PCIe Gen3 target cable adapter installed in the OSS target slot and up to one or more PCIe x16 expansion cards

Using a PCIe x1 card in a PCIe x16 slot You can get a hard PCI-E X8 to X16 riser, to let you put a half height GPU in a full height slot though you may need to make or modify the

pcie slot dimensions even though the slot may be wired as x8 electrically There is also the caveat that if you have a weaker CPU you may be gimped

as you have a Non G Processor that top slot should be running at full x16 speed the Top is coming Directly off the Last 4 PCI-E lanes

pcie x 16 slot For instance, you can place a PCIe x8 card into a PCIe x16 slot when the PCIe x8 slot has been occupied, but that card will always run in PCIe

Yes; As long as the card will fit in your case, a PCIe x4 slot can handle the card you describe Having no other information I can only guess
