As the web page mentions, I tested downgrading the PCIe bandwith from GEN2 to GEN1 without success. But after playing with different BIOS options, what did the trick was limiting the power-saving C-states. If I select "C7" as the maximum C-state, the card fails as described. After limiting the maximum C-state to "C6", it has been working for a whole weekend. > >Good feedback on the C7 vs C6 power state, thanks. You are welcome, Steve. Happy to be helpful. I will be at your disposal for testing purposes, if you need. BR
