RX580 display flashing under load

I have a RX580 8gb GPU that works fine until under heavy load with AI photo software. Then the monitor randomly flashes during the load event and returns to normal after. Sometimes the screen also goes green/magenta. The computer does not crash during this. The mobo is an old ASUS P8B WS which was bought in 2012. At around that time, ASUS revised the board from PCIe 2.0 to 3.0. I'm not sure which mine is. The idiots at ASUS don't seem to be able to tell me using the board SN. CPU-z simply reports as "PCI Express" with no version number.

 

The card is a XFX - AMD Radeon RX 580 GTS Black Edition 8GB. Do you think this card would saturate a PCIe 2.0 bus causing this issue, or do I have a bad card? Do you know of other software/ means to identify which PCIe version this board actually has?

Thanks in advance,

Lloyd
