Windows 10: GPU not recognised via powered riser

Hi guys,

I have a x570 ud gigabyte motherboard, with BIOS setting of Gen1 and 4g decoding enabled. The cpu being Ryzen 5, 8 gb ram, 30gb allocated virtual memory and GPU being 3060ti and 3070. The motherboard recognises the GPU via x16 as expected and also via unpowered riser connected through 1x slot, however through powered risers it refuses to work correctly, I have tried a LOT of different risers and have been unsuccessful in making GPUs work via them.

The powered risers do show the GPU in device manager and nvidia desktop notification , sometimes they show errors like Code 43 or No drivers present, but these can be dealt via disabling and enabling the device or/and reinstalling/DDU nvidia drivers, however these powered risers do not show the connected GPUs either in Nvidia Control Panel nor in MSI afterburner nor in Nicehash on Windows nor in Nicehash OS.

There is one more erratic behaviour these powered risers show, if the 3070 is connected via a power riser to the reinforced x16 slot , the GPU works as expected, it however doesn’t work in the same way when connected via a powered riser to other x16 or x1 slots, in addition the 3060ti via powered riser does not work as expected anywhere even via the reinforced x16 but works normally when connected directly to x16, the only difference which I could tell was that 3070 has 2 pcie power inputs and the 3060ti only has one.

GPU Riser question

This picture gives an idea of how close the GPU is to the motherboard when vertical mounted. I've circled the top most PCI slot where potentially the sound card could go above the GPU but it would depend on how tall your GPU is.

 

GPU Riser question

I don't think both the soundcard and riser cable will fit, I've looked into the same case before and also have a PCIE soundcard. That is the sad part about risers - you do lose your PCI slots. You may be able put the soundcard at the motherboards very topmost PCI slot depending on how tall the GPU is vertically....

 

I recently had the motherboard and riser card for the GPU replaced. Now I get the Blue Screen when I watch videos.

The pc manufacturer has been trying to help solve the issue, but with no luck. Does anyone know what I can do to solve this issue.

Perhaps I need to check the operation of the motherboard and riser card? How would I do that?
