Been moving parts around between home server and my gaming rig and am trying to get my A750 Limited Edition to work in a z690 with an i9-12700k. The VGA light comes on when i put it in the pcie 5.0 x16 slot on the top. I'll give an overview of the specs

Motherboard: MSI MPG Z690 Edge Wifi
CPU: Intel i9-12700k
GPU: Intel A750 Limited Edition 8GB
RAM: 32GB DDR5 (2x 16gb in slots 2 and 4)
NVME: Samsung 970 EVO 2TB (currently in slot m2_4)
PSU: Thermaltake 750W

PSU has a single 8-pin to the motherboard along with the 24pin. GPU has both the 8 and 6 pin from the PSU plugged in. NVME was moved to m2_4 to get them as far away from the GPU lanes as possible...

Running latest BIOS for the board, graphics boot device is PEG with multi monitor disabled. I had resizable bar enabled and i even attempted to force gen3 on the pcie_e1 to see if it would help with handshaking.

PC boots fine when the card is in the x4 slot below it. PC boots fine with a Vega 56 card in the x16 slot.

When the a750 is put in the x16 slot i get white VgA light on mobo with no video.

It looked like there was a known issue

but i installed this driver/utility when in x4 slot and checked the Intel Graphics Utility for the vbios version but it doesn't show the vbios version, all other details about the card are there .

did you set the slot speed to pcie 4.0 in the bios?

try this: plug the monitor in the motherboard and set the priority to iGPU (12700 integrated). set pci-e to x3, connect it to the first slot and then boot windows. next see if a750 is actually detected in device manager, if its not, still try to install latest arc drivers (sometimes it does nopt see the card before you actually install arc driver, not even microsoft basiic adapter)
