Journeyman III

No display port on PCIe slot 1

Naturally I assumed this was a DOA motherboard and the store replaced it immediately. To my surprise I'm having the exact same issue with a new board. I've tried 4 different GPU's so far. Display ports work fine on slots 2-4 and DVI works on all slots.

I've unplugged everything from the board except the GPU, CPU and 1 stick of memory in slot A1. I've also put in a stick of memory that is on the QVL in this configuration and the problem persist.

I'm not sure how the architecture works could I possibly have a bad CPU?

Thanks very much for all your help.

Is possible, the controller went out in my 1800X and caused me to incur near $300 in expenses as well as a month of downtime, though it sounds very odd, but it seems you've eliminated all the other possible causes. amdmatt​ you've one of these things, what's it sound like to you?


Thanks for your reply Black_zion, what do you think amdmatt?
