Ok so I went into BIOS and reverted to Optimized defaults. RAM is set at 2133, and all memory timings are the same in SPD and memory channels.
So I wonder if these RAM sticks are not fully stable on this Board "With Ryzen 3000 Processors" at XMP specs. I just remembered that the other 2 boards have Ryzen 5 2600's in them.
Makes me want to troubleshoot this further, wondering if it's a quirk in the memory controller on Ryzen 3000 processors.
Optimal defaults always does that to the Memory. It relaxes the settings so much, it can't possibly be unstable.
RAM works better if you set the frequency, timings and voltage all like shown in the BLUE box.
Remember... when you set the RAM at 3200Mhz in the BIOS... it will only show as 1600Mhz in CPU-Z.
That's normal. DDR stands for double data rate, which is why the RAM only shows 1/2 the frequency you set in the BIOS.

Is "memory training" a Windows function, or that of a utility supplied by the motherboard manufacturer?
If it's the latter, I'd uninstall it. (Personal opinion.)
A quick Web search just found Windows apps for memory training for people, not the PC.
Interesting. I have an Asus Tuf Gaming X570-Plus motherboard. Lower end than the OPs.
There is an "OC Tuning" feature in its BIOS. It searches for overclocking settings for the CPU and RAM. If I have played with it, I always reverted to the settings of my choosing. I'd be surprised if it ran repeatedly, at random.
That's not the same thing. OC Tuning just cranks everything up like 20% or whatever.
As for memory training, I get the impression it's built into the part of the BIOS we can't access.
It sounds like it, (only in time of severe need), fishes around for some sort of workable RAM settings, and it seems to do so repeatedly, until it finds some that work.
Like I said... the information about it is sketchy at best.
During the first initial boot of a board, after just building it, clearing CMOS, Changing the CPU or RAM module, the system will undergo what is called memory training.
By what I learned in college, memory training is the process of the system detecting the RAM, capacity, DDR4 voltage spec, and sets the RAM and CPU to work together, as all newer CPUs have the memory controller built into the CPU.
Once it has done it's memory training and booted the system, it supposed to save all of these settings onto the BIOS chip, and on a cold boot or warm boot, you should be able to do a fast startup because the board shouldn't have to go through the memory training again, unless you go into the BIOS and change the RAM settings.
I've been looking through forums and apparently the RAM training issue has been a problem on this board with Ryzen 3000 processors. Guess the problem gets worse if you try to get the Memory up to 3600 mhz, cause there is instability with the FCLK in the CPU itself. Some people have had to replace their CPU to get it running correctly.
GHot, I went on the ASUS QVL list, and also found out that my RAM modules are not on the QVL list, yet if I check Gskills website, it shows that the X570-E motherboard is supported with these memory modules. These memory modules are on the QVL list for my X470 ASUS motherboard though.
My board still has the memory training issue. When the issue is there, the CPU light stays lit for at least 5 seconds before moving to memory, vga, then boot. It starts with Q codes 14 and 15 at every boot, which means it's doing full ram test at post. When fast start up works, the CPU, ram, vga, and boot all light up in 4 seconds, plus the Q codes just go by so quick that it already says AA and the system is booting.
I'm inclined on installing my Ryzen 5 2600 to see if my motherboard has any change in behavior. I also may leave my RAM at 2133 to rule out either the CPU or the RAM
So I reached out to ASUS, and they told me that my memory kit is not on the QVL list, and that I should get memory modules that are best compatible with the motherboard.
Their recommendation for now is that I run the memory speed at 3000 mhz, or bump up the voltage to 1.375 and run at 3200 mhz speed.
I have bumped up the voltage to 1.375 and haven't had any booting issues so far, and my OS is still stable.
I'll post in a couple weeks to see if this made a difference.
