Hello Everyone, i need help from the experts with my chip, because i feel i'm doing something wrong. First and foremost, i always used Intel and my last CPU was a i7 870 which i used for quite sometime on 3.9Ghz using a NZXT Havik 140, so this is my first time owning a AMD platform. Currently, i'm using a ASUS B550-A Motherboard, 2x8GB 3200Mhz CL16 XPG memory sticks, EVGA CLC 280 Water Cooler and a XPG 750W Core Reactor PSU. I tried through Ryzen Master, BIOS (following some tutorials on Youtube) and increased my cpu multiplier to 40, and tried to set a stable Voltage to my CPU, which i failed miserably to obtain a stable 4GHz even with 1.4V, meanwhile i can get a pretty stable 3.9Ghz on 1.33V. Isn't that jump on Voltage a bit too much? I've seen lots of people achieving a stable overclock of 4GHz or more on a Ryzen 1600AF with, let's say, 1,375V or less, but mine can't get stable over 4Ghz, am i missing something? Do i have to mess around some other VRM configs? Change Load line calibration or something? Or perhaps i just got a very unlucky and got a chip that doesn't really like OC too much?
