I need to know if a PCIe 3.0 graphics card will work in my HP ProLiant DL160 G6. I messaged the seller, and they confirmed PCIe 2.0 is supported on the x16 lane, but unsure if a PCIe 3.0 graphics card would work in it. The BIOS version is 033, and if it is possible, do I need to update my BIOS? (Please include instructions on how to do that too, if I need to)
