Z490 Phantom Gaming-ITX/TB3 Slow Post and Bios

[eldrey]

Hi, My one week old built is:
Z490 Phantom Gaming-ITX/TB3
Intel 10900F
32GB DDR4 2400MHz Corsair (2x16GB) CMK32GX4M2A2400C16 Vengeance LPX

What I had done:
Update Firmware to latest
Disconnect Everything but Keyboard
Cleared CMS
Test All the parts with a diferent Motherboard all is Working

Everything was working normal but last night when I reset the system I notice a very Slow Post and Bios is very laggy. but Once I load the OS everything seem normal and a good speed. I also did some geekbench and seem OK. What can be happening? I have done nothing to the setting prior this issue. Should I return this Motherboard?

I would back to older BIOS but if the same is happening on older then maybe ask support. It looks like something is causing delays while loading hardware. You can also try with 1 memory module in 1 or 2 slot. Sometimes it's a single hardware incompatibility.
