Some GPUs are not leveraging the complete PCIe bus interface.
Some GPUs are not leveraging the complete PCIe bus interface.
Hey everyone, I hope everything’s okay. I’ve been seeing unusual results with my RTX 4080 Super plus Ryzen 7 7800X3D combo. After running some benchmarks and copying their settings, I’m getting about half the frames per second compared to what the creators showed. It’s strange since my setup and temperatures are identical. I checked GPU-Z and saw a bus interface listed as x16 4.0, but mine only shows x1 4.0. This might be one of the reasons for the lower performance. Anyone have any ideas or help with this?
You're likely asking about the specific motherboard model, GPU installation slot, and available SATA or NVMe connections.
It seems odd, but I think you've already updated your chipset drivers.
Everything looks good so far and there don’t seem to be any restrictions on the motherboard, at least according to the guide. The next thing is to confirm there are no BIOS limitations. Also, feel free to update your BIOS if you haven’t done so yet.
I'm attempting to reinstall the AMD chipset drivers again, but I haven't adjusted the BIOS settings for PCIe connections yet. The only thing that's active is rbar by default. I've checked the PCIe slot and the GPU itself, but no visible issues were found.
GPU-Z does not display this during gameplay. Running it while gaming usually causes poor performance, such as stuttering.
I’m not installing a riser, only using the 600W 12HPWR Connecter that came with my ATX 3.0 PSU.
