Hi,
i have a tiny question on PCIe lanes. My Mobo has 2 PCIe x16 slots. The manual says that both of these ports operare in x16 modes, but if two gpus are connected they are scaled down to 8x modes.
However, it seems that the lanes are scaled down if ANYTHING is connected to the 2nd PCI x16 port,not only a GPU. My first PCIe x16 port holds a Gedorce GTX560 and the second a tiny PCIe x1 wifi card. However according to GPU-Z, the GPU is in x8 mode. Is that because of the x1 card in the other slot? Is this behaviour normal and expected?
I know that x16 vs x8 probably wont affect GPU performance significantly, i am just curious...
Thanks
