Question X570 Taichi and GSkill Royal 3600 Problem

Sep 19, 2019
Hi to all :) I'm new to this forum but I've seen that your collective knowledge has helped thousands of people, so I'm here humbly asking for your help
I have a big problem with my new config
I bought AMD Ryzen 5 3600, ASRock X570 Taichi and GSkill Trident Z Royal 3600 CL18
Problem is that motherboard wont boot with rated 3600 speed, it goes into a boot loop and after 3 tries defaults to 2133
Memory is CL18-22-22-42 1.35V rated for 3600MHz, unfortunately today I found out that chips are from Hynix.
I got it running on 3000MHz with same timings but only if I set IF to 1500MHz
It's quite frustrating not being able to get it to run at advertised speed.
Can someone please point me to what I need to try to get that 3600 and if can recommend some tighter timings
I switched from X79 i7 3930k platform to AM4 X570 hoping all will go smoothly but alas problems are mounting.
This is my first AMD config since Athlon64 X2 and any help, tips and comments are appreciated :)
