Hey everyone, I'm facing an unusual issue I've never encountered before. My motherboard is an Asus Strix X299 E-Gaming model, but it no longer has a PCI slot. To work around this, I purchased a PCI Express RISER card to connect my old TV tuner. The tuner is a TT-Budget C1501 DVB-C model.
I followed the installation instructions carefully: I placed the riser in the PCI-E slot, connected auxiliary MOLEX power, and confirmed in Device Manager that everything was working fine. However, when scanning for a cable, I couldn't find any signal—only PAT is set to RED, and the 0 channel appears. I checked the TV cable on another device, and it worked perfectly; the cable itself seemed fine.
Could this riser card be incompatible with my tuner? Is there something hidden going wrong? It's strange because Device Manager says everything is normal, and my tuner is functioning properly too. I tested it on a different PC with a standard PCI slot, and it worked without issues.
I'm really confused—why wouldn't the new motherboard have at least one PCI port? I really dislike this situation. The tuner is great, it delivers excellent HD quality, and German TV tuners are known for their reliability. The riser card is brand new with a two-year warranty.
What should I do? Should I return the riser card? I'm unsure how to prove it has problems since Device Manager shows no issues. Even if I return it to warranty, they might just send it back unchanged. I hope I posted in the right section, but if not, please help me move forward. Thanks!
It seems the card may not work well with the riser you're using. Losing many data lanes from x16 to x1 suggests a compatibility issue. If your CPU has integrated graphics, consider removing the GPU and testing in another slot. Your i7-7820X lacks integrated graphics, so try it on a different machine to confirm. This could help pinpoint the problem.

It seems the issue likely relates to DMA and how it interacts with the riser controller. These riser units probably aren't suited for running very old PCI cards, such as those from 2003 or earlier. You might consider launching a Windows VM and using PCI passthrough instead. I assume the tuner is still functional. However, after someone discovered that DVB-C cards could be exploited for satellite hacking about a year and a half ago, they were likely seized—especially the PCI-E ones.
I believed I was the only one using this riser card globally. I thought no one paid attention... when I took it out of the slot, I noticed the yellow cable was damaged. I didn’t know how it happened, so I soldered it back, and now it’s functioning. The cable is +12V. All four wires seem very weak—they were poorly soldered at the factory. I use this special tool to fix the yellow cable.
