Ryzen 5 1600, Should I OC the RAM from 2400 to 2666?

Should be fine to move upto 2666MHz, with a Ryzen the faster the ram, the better it works. Just don't try and adjust secondary or tertiary timings manually, leave that on auto.

I just bought a new AMD Ryzen 2200G and ASRock AB350M Pro4 motherboard. I'm using 16GB(2x8GB) Patriot Viper DDR4 3000MHz (11BF2) memory sticks in dual-channel mode. I've had the system up and running at 2934MHz but I had to go into the BIOS and basically just changes values like some mad scientists to get it to work. I have no idea what most of it means. I'm back down to running @ 2134MHz because I don't have a clue what I am doing.

I'm pretty sure I did what you just suggested the OP to not do.

You sound like you know a lot about memory timings. I've never heard of the terms secondary and tertiary timings. I wish the ASRock BIOS would present those to the users as such. Something along the lines of:
"Level 1 (primary) memory timings" - You can play with these without blowing up your system, knock yourself out.
"Level 2 (secondary) timings" - These require more advanced knowledge and skills to set up properly, be cautious.
"Level 3 (tertiary) timings" - Do NOT touch these unless you know exactly what your are doing. You have been warned!

Of course, in the old days you could probably blow up your PC by doing things like this. But in all honesty, I have to ask this question now that were on the subject. Don't they have built-in protections these days that will shut down the PC immediately if things get too hot?

Was your advice not to touch secondary and tertiary settings because you could do irreparable damage to the system or were you just trying to save the OP some wasted time. As in, "you won't hurt anything but you probably won't get anywhere useful so don't bother trying." ?

The later. Primary timings are what everybody sees, in the case of ddr3 1600, most all that speed ram was default at 9-9-9-27. The first 9 is the Cas or CL, so you'd see listed in Amazon the Patriot Viper 3 1600 CL9. But thats just primary. Some more involved mobo's or bios software such as MSI Control Center, will not only show primary, but also secondary timings. If primary are the timings associated with the in and output of data, secondary are the timings associated with how the primary deal with the data, and tertiary are less significant, but still important. Between the 3 there are about 40 or so timing settings, 4-13-23 I think.
Changing a CL9 to a 10 or the 27 to 24 isn't much of a big deal, if the ram is stable, it's stable. But changing a 200 to a 20, in secondary and there's 5 other 20's listed and you forgot exactly which one was changed will create a bunch of instability. Secondary and tertiary are really ram important timings, not data important timings so not really anything that needs changing.

2933MHz is quite normal for most ram on Ryzens, especially if not with a current bios update that includes many microcode fixes. Afaik, the Patriot elite was the only Samsung B-die series and had very few issues with 3000 or 3200,but the Viper I believe is SkHynix OEM, so did have issues getting past 2933MHz. That's been fixed.

Well, I bought these memory sticks about 3 years ago when they (Patriot Viper DDR4 3000MHz) first became available to the market. It sounds like I got the bad sticks. When you say SkYnix had problems getting past 2933MHz but it's been fixed do you mean in a BIOS update or do you mean if you buy new memory sticks today that are Patriot Viper that they are of higher quality these days? ASRock shows my memory model as being 2933MHz compatible with their AB350M Pro4 motherboard but only if it's the (11BF2) memory kit. I asked Patriot support if there was a way to check if mine are (11BF2) sticks and they said not that they are aware of.

Patriot is just like most other vendors, they design the ram and have OEMs build it for them. They'll use Samsung, SkHynix and a few others, so it all depends on the line, or even the speed rating as to who the original OEM is. Crucial is Micron consumer brand, Kingston, Samsung is its own etc, but Corsair, g-skill, Patriot are just bought.

Yes, microcode updates and bios updates have fixed almost all Ryzen ram issues.
