I'm using the DDR4 DIMM.2_SLOT with 2x M.2 drives and the M.2_1(SOCKET3) with an M.2 all M.2's are PCIe 4.0 types. Yesterday I watched a video posted by Der8auer on YouTube entitled 'I tried to repair my RTX 4090 and killed it ' where we are using the same MOBO using different RTX 4090s and both of us have the same reporting of 'PCIe 4.0 8x.' Also obviously I double checked the 'shared' limits for my MOBO. is GPU-Z picking up on the 'x8' on the PCIe 5.0 side and reporting it as PCIe 4.0 'x8' and if so what is the actual bandwidth to the RTX 4090? My ASUS ROG Extreme Z790 has a PCIe 5.0 x16 Bus Interface and my RTX 4090 has a PCIe 4.0 x16 Bus Interface, I'm crystal there.
My copy of GPU-Z (version 2.51.0) reports Bus Interface as 'PCIe 4.0 8x' on my PCIe 5.0 Slot / PCIe 4.0 GPU.
