Asus Z390-E Gaming Bios Best settings?

[FullMetalAlchemist87]

Hi,

It is time to set up the Bios after the first boot, but i am a bit lost (especially when viewing the advance mode).

MOBO: Asus ROG Z-390 E Gaming
CPU: I9-9900K
RAM: HyperX Predator 4x8 (32Gb) 3200

At the moment i left basically everything as default/auto except I:

1) changed the QFan settings so they are good for my fans setup (thanks to the suggestions i got in another thread)
2) enabled the X.M.P. profile (XMP I) from the EZ mode (I clicked "NO" when asked would you like to enhance the system performance with the XMP settings? should have i select "YES"?:

3) should i turn on "Intel Rapid Storage Technology"? Please note i have 2 SSD and 2 HDD SATA (not connected yet)
4) AI Overclocking: Should I leave it on "NORMAL" or go for "AI Optimized"?
5) Should i do anything else?
5) Last questions, should I updated the bios or not? i know it is a risky task..

If you don't need to overclock, you can set everything to default settings, but activate the xmp profile.

Bios update only when you have problem

Ok, perfect:

just to be sure, should i use "Intel Rapid Storage Technology"?

Why in the DRAM section it is still indicated 2400Mhz? i thought that the value would have increased to its maximum (3200) when enabling the XMP, sorry if it is a stupid assumption.
