Review on LINKUP - Extreme4+ PCIe 4 by Jon Hill

Didn't work initially. I tried setting the PCI Express slot to 4.0 and Auto and it crashed for a few minutes while playing, regardless of the settings. What I have found works for this. Update the motherboard BIOS to the latest version. Mine was released in late 2019 and didn't work. Please note that your settings may be reset during the upgrade, so set the PCI Express slot to 4.0 after the upgrade. Also update your graphics driver to the latest version - mine was a few months old. With these two updates and changing the mainboard settings, I have not noticed any instability as of August 2020.
