Can the expert enlighten me about the PCI-E speed for my Laptop Nitro ANV15? I noticed that the speed is fixed at x4@4.0.

As shown in GPUZ, the RTX4050 supposed to support PCIE x8@4.0, I even run the "Render Test" but it still stuck at x4@4.0.

All the power saving mode had been turn OFF, and even the power management for RTX4050 had been set to "Maximum Performance" in Nvidia Control Panel.

Appreciate any feedback as my curiosity is killing me. 😅

Edit:

  1. The processor is Intel i5-13420H, with 16GB 5200Mhz ram and 2 SSD.

    yes, you are right RTX 4050 supports x8@4.0 but the processor (i5 13420h) has only 8 pcie gen4 lanes and they are shared between GPU(using 4 pcie gen4 lanes) and Gen4 SSD slot( using 4 pcie gen4 lanes). so total 8 pcie lanes at gen4 got used.

    i hope you got this.. thanks.
