A couple of days ago I got an apparently new 14700k cpu I was planning to use with my strix z690-A D4 + 64gb DDR4 4400 + 3090Ti. Currently I use a 2 year old 13600k (always everything in auto in bios) that it's behaving weird with temps since around 1-2 months ago (high temps, noisy fans... I managed to solve a bit manually undervolting).
When I try to use the 14700k the GPU is not detected in the pci-e 16x. Using the iGPU everything is working fine, windows starts, running cinebench and everything is apparently OK. I managed to output image putting a 1080ti in the the secondary pci-e port, but same card is not detected in the main port (3090ti does not fit in secondary port so couldn't test).
Moving back to 13600k, GPU is detected again and working fine.
I tried using latest Bios 4001, resitting gpu, removing and putting back, downgrading bios to 2802, using manual value for pcie 16x port (tried from gen 5 to gen 1)... But nothing worked, gpu is not detected (if I'm not wrong it was showing a x0 in Bios port speed).
According to data, 14700k should work fine in my mobo, but not sure if something is wrong or there is something I'm missing...
