Hello all,

I've recently purchase a 6900 XT from AMD, my cpu is a 3700X and my motherboard a X470 gaming plus max.

My system work with my old RTX 2060 super but not with my new 6900XT. I've tested my PSU of 850W on an other system with my 6900XT it works.

I have the last stable BIOS, an idea ?

All PCIe power cables are connected to the card? Have you tried the different graphics ports of the card (DP and HDMI)?

The two PCIe power cable are connected. I just have an HDMI cable entry on my monitor...

I would like to use my 6900XT to connect with my HP Reverb G1 helmet (reason why I need a powerful graphic card)...

And you have tried this card in another system via HDMI on the same monitor?

Yep not sure what card you got but switch over to the other Bios on the GPU if it is a dual bios card as your not helping by not supplying model numbers.
