Ryzen and ddr4 memory

[Noobie22]

Hi!

I build my ryzen pc and I have had several problem, some of which I have solved, but this is strange. I have overclocked my Ryzen cpu to 3.6Ghz with 1.2 voltage, i know it not even really good overclock, but it has lower voltage than Asus own overclock settings, tpu 1 and 2. I have ddr4 memory, with base speed of 2666Mhz. Currently pc running at 3,6Ghz, 1.2V and 2400Mhz memory speed, when I change ram speed to native 2666Mhz with D.O.C.P or even without it(manually sett timings etc and adding more dram voltage), computer boot loops 1 to 2 times before post and then continues succesfully and when I go to bios after post it says 8GB of memory, when I should have 16GB, but motherboard(Asus B350-F gaming) still detects the memory, but doesnt use it for some reason, but sometimes it uses it and shows it on bios but still does the boot loop for a few spins before going to bios. This happens on every settings, Asus overclock tpu 1 and 2, on auto memory settings, but works perfectly fine when I lower the ram speed to 2400Mhz with dram voltage of 1.2V, no boot looping and showing all 16GB of ram, stability perfect.

Can you help me?
