Hi guys unfortunately both tips did not help with my strange boot issue. Logo option suggested by Grnfinger does light up the Logo on motherboard (we do not want that ;) ) and quick boot does not affect this strange thing with "esc" key.
I will try 1602 from other bios - but I remember I was able to turn it off somehow in 1602. Maybe I got bed flash of 1802.
That is very nice RAM you got there. Sergio can you post everest test for your settings.
Thanks
