Ok, so, I alluded to this in another thread, but I did some further testing, to see what I can come up with.
Specs are listed in the spoiler in my sig, the PC called ChromaTron.
The BIOS in the motherboard only allows memory voltage to be altered in 0.05V increments.
Right now, everything seems to be stable setting the RAM to 3066MHz, and using only 1.25V, and Memtest86 can makes four full runs of all tests (the ones available with the free version) with no failures.
At 3200MHz, I get failures at the default 1.35 voltage. It also fails at 1.40, and 1.30, and the system will make 3 attempts at restarting if I attempt 1.25V at that speed, until it gives up and automatically resets to 2133 after the third try.
My questions are:

My questions are:
- Given the specific version of the 1600 I have (seems like it's closer to a slightly slowed down 2600 than to an original 1600), my motherboard, and RAM, does this indicate that there's a hardware problem (not-quite-up-to-spec RAM, or something else), or is 3200 generally considered particularly ambitious for a B450 motherboard combined with a Ryzen 1600 or 2600?
- If 3200 should be easily doable, then what am I doing wrong?
- Side note: I don't know what flaws or imperfections make a 2600 into an F-stepping 1600? Not quite able to hit the same speeds? A memory controller that's not quite as good? Some other thing(s)? I honestly have no idea, and I'm not sure AMD has revealed that info.
- Assuming 3200Mhz is out of the question for me, and 3066 is the best that I can do, then is that speed ideal? I know I read somewhere that (at least with regard to the 3000 series Ryzen), that RAM speed in multiples of 266.66Mhz are preferred. Is this also the case for Ryzen 1600 and 2600?
- If so, then since the next step down from 3200 (12x266.66) is 2933Mhz (11x266.66) am I actually better off setting the RAM speed to 2933 than I am setting it to 3066?
