Hi all,
Been lurking for years, but fortunately I've never been stumped enough to need to post.
Here is the issue:
I purchased a new MSI B550M-VC WIFI motherboard and a Ryzen 5 5600x cpu. Everything else I had already.
Let me say this first: I have an old 1060 6GB card that I tried it and that worked fine inserted into any of the PCIe slots.
The GPU I want to use (Powercolor RedDevil AMD 6800) will not work unless I use a powered riser. It's a sata powered riser, so I don't want to use this long term, even though this isn't going to be used for long amounts of time. Just a PC to watch exercise videos and Zwift bike rides.
When I insert it into any PCIe slot the VGA light on the motherboard lights up and there of course is no image. When I use the powered riser, it works fine and also reports as x16 Gen4 on the MSI board explorer.
I tried different PSU's, I've updated the MB BIOS to the latest available, and I've tried the OC and the Silent switches on the GPU.
Anyone have any ideas why the 6800 will only worked on the sata powered riser?
