RAM issues?

Not sure where to put this, in this section or in Memory section but since it's related to overclocking (on memory side), I'll go ahead and put this here.

As of few months ago, my RAM no longer can run at 3000MHz or higher. (I tried with 2 different set of RAM, TridentZ RGB 16GB 3000Mhz and TeamGroup 8GB 3200MHz, when set to RAM's max speed, system either fails to boot, it power cycles, I get a kernel panic or system completely freezes if I'm logged in, as long as I run it at 2933 MHz (or lower), it's fine.

But for months before it happened, it was running at their max speed, had no issues, what changed? Haven't touched anything in BIOS, it's like it just suddenly happened and since then it's been like that.

CPU's always been OC'd to 3.8 GHz (Ryzen 5 1600), but even at stock with RAM at 3000/3200 MHz, it still freezes.

Yeah, but as I mentioned, they ran at their rated speed for months without a single issue and then suddenly they no longer can do that, regardless of what RAM (G.skill 2x8GB 3000MHz or 2x4GB TeamGroup 3200Mhz, tested with either) I use, which suggests the issue is probably with the CPU or motherboard or something else.

I did memory tests at 3000/3200 MHz for either set of RAM, no issues, for months I did various things, gaming, mining, rendering, etc, PC's been on pretty much 24/7.

8GB @ 3200 MHz for couple of months, then I needed more RAM, so I upgraded to TridentZ 16GB @ 3000 MHz, ran fine for another couple of months, doing same things I mentioned, then system started freezing when I do anything CPU demanding, so I dropped it down to default/2133 MHz, which was stable for a bit, then upped it to 2933 MHz to gain a bit more performance, still stable and left it at that ever since, but that's after I swapped back to 8GB RAM because RGB lights on 16GB RAM was annoying me, no way to control them on Linux or in BIOS/UEFI, I've only ran Linux (Xubuntu 16.04 then 18.04, to be specific) exclusively on this system.

Everything's on auto, except for CPU, which is set to 3.8 GHz @ 1.325v (3.8 GHz seems to be the ceiling for my CPU, anything higher and it won't boot, no matter what voltage I give it, but that's not the issue here, unless it's somehow related and I'm missing something, just curious, what settings are you using for 4 GHz?).

Motherboard is ASRock Fatal1ty AB350 Gaming-ITX/ac, haven't done any BIOS update, it's running at whatever it came with, but it's one of the versions without support for Ryzen 2xxx series.

Hmm, I'll get around to resetting everything and redoing all OC settings.

My PSU is Corsair SF450 gold, neither CPU or GPU consumes a lot of power, GPU is left at stock, no OC at all and my SSD is a m.2 form factor that's slotted in under the motherboard.

My motherboard does support Ryzen 2xxx series but I'm running a BIOS version that doesn't have the support for them and I haven't updated yet.

Also, that thing you mentioned that allows RAM to run at higher freq, you mean XMP? It's what I'm using to run at higher speeds.

Yeah, I was thinking about just leaving them at 3.8 GHz / 2933 Mhz, it works and I'm happy with how it performs, 2933 MHz isn't far from 3000/3200 MHz anyway.

I'll do a reset and check everything if it no longer can do 2933 MHz stable.
