Description of PCI-E 4.0 riser problems
Hello, I'm organizing my upcoming upgrade from a 2700X to a 5700X3D and replacing the Nvidia RTX 2070 with an AMD 7800 XT. My case is a Silverstone FTZ01 ITX, and I need a riser card or cable for my GPU. There are reports about problems with AMD CPUs and riser cables for PCI-E 4.0, but I'm not sure what the issues are or how to fix them. I want to confirm if these problems have been resolved and what signs to watch for. I plan to use the Silverstone RC06 riser card, which fits my case perfectly, but if I need a different cable, which one should I choose? Thank you for your assistance.
I don't remember any particular AMD problems with risers. Most issues seem to come from the risers themselves. Since electrical paths are delicate, a low-quality or damaged riser can cause problems. Gen4 risers appear more reliable than Gen3, though I've used a CoolerMaster Gen4 with no issues (paired with a 5900X and RTX3080).
Do you have a riser in your latest assembly? The reason you might need one is to bridge compatibility gaps—like supporting PCIe versions beyond what the riser can handle—or to accommodate GPUs with specific lane configurations that don’t match your setup.
I have a Silverstone FTZ01 setup, which relies on a riser card to link the GPU with the CPU
