    Also, when you put the RAM in did you install it in the right order ?
    For Asus it's A2 then B2 then A1 and B1.
    A2 is second ram slot away fromcpu and B2 is the far right slot.

    There geenerall isn't a setting for single or dual channel. If you install the ram in the order your motherboard manual specifies and then do F5 optimized defaults, then do any UEFI/BIOS customizations you want followed by pressing F10 to save your settings the motherboard is smart enough to know whether you have single/dual/quad channel ram installed in your PC.

    I formated my windows and installed new one. Also i did flash for new bios and also did f5 to defult. I cleaned with air the slot carefully. Only thing i didn't do yet is the rtc change. I will try and come back. But i can't find setting for single to dual channle in asus utilities?

    Your first attachment clearly shows/states your RAM is in single channel. You must change that to dual channel as Berton suggested. Consult your mobo manual to do this.

    Dual or single channel may be just a function of RAM sticks being in pairs in each of 2 IMCs (Internal Memory Controller) in the processor. A pair of same RAM sticks in one IC channel will run in dual channel. Try them in pairs and see if any channel is not working properly.

    Nothing changed for all tries soo far

    I also know from experience with my old pc's Asus Sabertooth 990 FX R2.0 mobo and AMD FX 8350 cpu that the UEFI doesn't like 2400MHz RAM, you need to keep it at the 2133MHz. settings in the UEFI or you'll have issues.
    I know this because I upgraded the RAM in it to DDR3 2400MHz RAM and it wouldn't work as DDR3 @$))MHz. RAM with the Asus mobo and FX 8350 cpu. It has to be set in the UEFI as DDR3 2133MHz. RAM.
    Do you have setting for that to try?
