Is riser cables the reason with my black screen on boot?

[Memes]

I have my GPU vertically mounted using the Phanteks Vertical Mount but sometimes nothing comes up when I boot up my PC and on the EZ Debug Light theres a VGA light on it. Performance is fine but just a bit annoyed with the black screening but resetting it fixes the problem and been seeing recent videos on riser cables and now the new video on Hardware Canucks also shows the problem for it. Should I change the PCie lane to gen3 or just leave it at auto for now?

There does seem to be a lot happening with PCI-e riser cables lately, makes me wonder about the future, if it will even be viable to run, with things like 4.0 being more supported, or even 5.0.

If I was you, I would try turning the PCI-e mode to 3.0, see if that fixes your issue, if it doesn't then try the card in the slot without the riser.
Only way to rule out the riser cable is to remove it.

Shouldn't be to much trouble, maybe 15 mins.

Yea I switched it over. Hope it stopped with the black screen when booting up.

Thanks, but I've already seen the video.

Let us know how it goes, and what other hardware you have (motherboard and GPU)

Got a Asus Rog Strix 5600XT and a MSI B550 Gaming Edge Wifi. I probably got the motherboard that doesnt make it complicated with the riser cables unlike some people with no POST and other issues. Games ran fine no performance drop what so ever just the no boot screen

I ran into the same issue here with a small form factor build and also fixed it by changing the motherboard setting from pcie gen 4.0 to gen 3.0 via the bios. The low profile case uses a specialist pcie riser interface to allow full graphics cards to be installed however not keeping up with the times the vital component is pcie gen 3.0.

Also note whenever I flash the bios, the motherboard goes back to pcie 4.0 by default, with an MSI b550i anyhow.

Low quality risers do tend to have issues
JayzTwo recently did a video about one

Probably that as well
