Hey, AMD RADEON HD 7770 x2 setup. When you run two cards in CrossFire, it sometimes shows two GPUs or one GPU plus a Wi-Fi card. From what I found, this happens because your chipset lacks enough PCI lanes, causing it to randomly switch between the second GPU or Wi-Fi card during restarts. You can’t have both active at once. Looking for ways in the BIOS to narrow the bus width per GPU—like 8x2 or 1x4 for Wi-Fi—to improve performance. Any tips or tricks?

Which slots are connected to the board? It shouldn't change unexpectedly, probably due to a poor connection on the second GPU or Wi-Fi card. The second GPU is also running on the Lanses chipset, which means it will be significantly slower than expected.

GPU1 is the main PCI port, GPU2 has a second 16x long PCI slot. Wi-Fi is short-range (two units?), PCI slots work reliably once removed, and WIFI appears consistently.

I'm still uncertain about the issue. Could you attempt inserting the Wi-Fi card into a different slot? There are two options available on that board.

Attempted to refresh bios, but it doesn't assist regardless of what I do. Unless I disable the wifi card, Crossfire X remains inactive and isn't listed in the AMD settings. (Limited PCI lanes/Speed)
