4080s PCIe x16 issue
Hello everyone,
I found a reasonably priced RTX 4080 SUPER 16GB VERTO. However, the seller claims that although the card works when installed in a PCIe x16 slot, it only operates at PCIe x4. He says he purchased it in this condition and has been gaming with it without experiencing any issues. According to him, the performance loss is only around 2–5%.
Is this claim accurate? Could running an RTX 4080 SUPER at PCIe x4 noticeably affect performance, and is there any way to repair or restore it to the proper PCIe x16?
