X570 Taichi - Not booting properly / Bios resets

   If I can read what Ryzen Master says my VSOC is 1.1v and VDDG is 1.0979 so it's a bit too high?

	Somewhere below VSOC it's fine. For example VSOC at 1.1v with LLC3, VDDG CCD at 0.95 (doesn't seem to change much changing this value) and VDDG IOD at 1.05v is fine for 1900 MHz FCLK. If that's not stable, then the CPU can't do 1900.

	Random reboots and memory training issues seem to be solved since bios v3.80. @foxx1337 How can I check if VDDG IOD is right?

	That's an unstable Infinity Fabric clock or voltage (VDDG IOD) and it has nothing to do with the BIOS version.

	I have this problem since very first bios (v2.80). I tried all bioses up to 3.60 and now bios reset due to xmp profiles is very rare but persists. Latest bioses come with an additional issue: suddenly reboot when Windows is idle. Windows system event log reports error WEHA-Logger Event ID 19.

	Hello! Same issue here. I have an X570 Taichi with a 3800X, with 64 GB of Trident Z Neo (GTZNC) memory. The problem is with the memory since the 3.xx UEFI upgrade. I get the error code 14 or 15 (memory related), 3 cycles, then all UEFI settings are reverted to default. I believe the most stable verion was the 2.7. After upgrading I am receiving multiple BIOS related issues during operation, like access violations, watchdog protocol error, it is getting better with the newer versions. I am only using XMP profile on the memory, and used the Fan tuning to set the minimal fan speeds.

	I also had this problem with Asrock X570 Steel Legend WiFi Motherboard, with Ryzen 7 3800x and G. Skill Trident RGB F4-3600C16D-16GTZR CL16-16-16-36. What I found was, that after shutting down at night, then restarting next day the Computer resets the Bios to defaults, I changed from Bios 2.6 to 3.0 but still the same. I have found a way to prevent this but then cannot use USB 3.0 port to charge devices when Computer is off. The method I use to prevent Bios reset is, when I shutdown, I immediately turn off the "Power Supply Switch ?t back of the Computer, next morning I turn on the ?ower Supply Switch??followed by the Computer Switch and everything is good, this has worked for 10 days now. Apart from this problem, the Computer runs great, is running at 3600Mhz.

	It's sounds like it attempts memory training at 3600, which is I believe 3 reboot cycles by default, and when the memory training fails, it resets it to JEDEC spec (2400 or 2667) and boots with that. Running memory overclocked depends not only on the sticks (the XMP rating), but also on the memory controller in the CPU, and few voltage settings besides the RAM voltage that gets applied with XMP (VDDP, for example). So just selecting XMP in UEFI might not be enough to get a stable overclock. It also depends on how many sticks and memory ranks you have. Having 2 single rank sticks allows better overclocks because it's easier for the memory controller to manage, adding more ranks and sticks tends to drive stable clocks down and timings up.

	Very good. Thanks for your response. I am out of ideas and probably wont be testing anything until I hear from Asrock. I emailed them today. I was thinking to take out one of the RAM's and fault tracing, but I guess this really is on the motherboard side.

	The dersciption of your issue, is very similar to mine one. Power on, fan speed, then go down, asrock logo, black screen, then starts again and goes to win10 but with ram and fan tuning resetted. All this happens randomly, not always. however, if you are testing something that works, publish your results, it would be very useful. For now I have made a bios downgrade to the penultimate version, the one with agesa 1.0.0.3, and the situation seems to have improved, almost five days without issue Regards!!!
