No, your network card and GPU PCIe revisions won't conflict.
PC Specifications: Gigabyte P8P67 LE Intel I7 3770, 32 GB DDR3 at 1600MHz GTX 1070. Currently using a Realtek 1GB on-board adapter; other details pending. I’m exploring a PCIe Gen 2 network card for my GTX 1070, wondering if it would transition to Gen 2 and impact performance. I’m considering a PCIe Gen 3 card or a TX401 in an X4 slot. Would swapping to an X4 card affect the X16 lane? Also, adding an X4 card to the X16 slot might shift the X16 lane down to X8. Thanks for any guidance! Links provided below. (Note: This may not fully clarify your question.)
From what I understand of the manual, you have several PCI slots arranged in specific configurations. The top slot is full width with up to 16 lanes, the middle slot is also full width but limited to 8 lanes, and the bottom slot is full width with a maximum of 4 lanes. Above the graphics there’s one lane, and below the graphics there’s another lane. The bottom slot (PCIEX16_3) connects with two smaller slots—USB3_34 and eSATA12—which share the same capacity. By default, it supports only a single lane. The first two full width slots (PCIEX16_1 and PCIEX16_2) can share lanes, and the CPU divides them when the second slot is active. Using PCIEX1_1 (which is under the graphics) or PCIEX16_3 would likely not affect the graphics card. If you install the card in the second PCI-E slot, it probably loses 8 lanes and reverts to PCI-E 2.0, possibly because CPU lane allocation behaves differently than chipset lanes. If the board can negotiate four lanes for the second slot, your GPU might drop to eight lanes while retaining PCI-E 3.0 support.
I'm cautious about both options without understanding their chipset. I'd only receive an Intel i225 B3 or i226 for 2.5Gbit (PCIe 3.1 x1) or a previous Intel 10Gbit server card (assuming the bottom PCIe slot is x4 and doesn't overlap with other x16 slots), ensuring it has Windows 11 drivers.
