[SOLVED] 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?

You use slow memory. Why did you choose this kit ?
According to the QVL for your mobo, here are the RAM sticks that are compatible, with speed up to 3600 MHz

Hi, in that list they have others 2400MHz. I understand the memory can affect a bit but not a 500% drop in performance
