x370 taichi reset on cold boot

I actually do have advance boot training off. Only time I got a BSOD was when I tried fir 4ghz for fun. It just all strikes me as strange. I have just been leaving it at stock as of now. But at that point I would've gladly payed extra for like 1700x or 1800x.

I am able to boot and stress test just fine, then restart and slowly increment clock speeds or maybe ram and stress test again. Then at the end of the day when I shut off my computer. No matter how mild the overclock, the x370 taichi will do a couple of boot loops and reset my settings. When this does happen getting into the bios seems to be extremely laggy/choppy and takes quite some time to post. (reset also happens when I overclock through ryzen master) I have the latest bios update at p2.40 and my pc is running an R7 1700, 1080ti, x370 taichi, gskill flare x 3200. Would this be a defective motherboard or is this a software issue?

I have experienced the same behavior sometimes with my X370 Killer SLI/ac board, using a 1700X and G.SKILL FlareX 3200 memory. In my situation, I have not fine tuned the memory enough (apparently) to run at 3200, and get much better memory stability at 2933. My CPU OC to 3925MHz is not the problem.

While the FlareX memory stability at speeds above 2933 are partially at fault, the source of the boot loops and option resets is the AM4 Advance Boot Training option, enabled when set to Auto, the default. Disabling the AM4 Advance Boot Training option (OC Tweaker screen) has caused the boot loops to stop, as well as the UEFI option setting resets. At least it has for my board, memory, and UEFI version, which has the same AGESA update as yours. Any failure of the training (which should be related to the memory only) will cause both the CPU and memory OC settings to be reset, as you have seen. Why both CPU and memory OC settings are reset, I don't know, that simply seems to be how it works.

The difference in disabling this option is memory instability will cause a quick BSOD in Windows. If your memory is stable, you shouldn't get a BSOD.

Unless your 1700 CPU is very poor for over clocking, or your VCore is too low, IMO a slight memory instability is the only problem you have. As you said, even a small CPU OC seems to fail POST, but in my experience a failed CPU OC fails very early during POST, and never gets to the Boot Training phase. IMO that option is of questionable value, and I suggest disabling it for a few days to see how the PC behaves.
