Hi guys,   The time to separate with my beloved HP DreamColor 8770W has come. I managed to get for a reasonable price of 1150€ Clevo P775TM1-G with 9900K, RTX 2080, 32GB 2400 DDR4 and 144Hz IPS screen. As it is a new field for me (outside my comfort zone:) I have several questions to you and would be very grateful if you could give me some hand on some, why not all?:)  1. Do I need unlocked sbios in case to control the DDR4s timings and would be wise if I upgrade the RAM
