AM4 BIOS info

I dunno beecause even without XMP I had some issues. Bizarre stuff, so far I really liked the board but these issues with new BIOSes are annoying. Maybe at some point I'll try a new kit of RAM, but I think I'll stick to the old BIOS, not precisly my best time in terms of finances so I do not have many choices. Good luck with the new Asus mobo man! and thanks for the help.

It will crash when trying to initiate windows, if I enter in SAFE MODE I can restart and everything seems fine. No issues while using it. I will try what happens if I disable XMP on my RAM with the newer BIOS like the latest I have now installed. It's annoying because I really want to use some of the newer features that new BIOS brings to the table like SAM for instance and I can only manage stability while starting my PC with 1.10 Bios or prior ones. I have the same MB but my RAM kit is CMK64GX4M2E3200C16 2x32GB which is not the on QVL. With the latest BIOS, my PC resets (like power off then on) in the first 5 minutes when I start it up from off or when I restart it from windows. It happens like in 4 out of 5 startups. If it does not reset in the first 5 minutes, it will continue to run stable for a few days until I shut it down or restart it from Windows. Is your problem the same?

Yeap is more or less the same. The thing is that I've tested my RAM and they have no issues and right now I'm in BIOS P.1.10 and everything works fine, not a single re start out of nothing, nor any problem with cold boots.

I'm starting to think that might be more CPU related, like if some new features doesn't play well with my 3900x.

This forum is incredibly dead, not a single Official rep that might help. Did you tried any other way to contact Asrock about it?

BTW like you, my restarts or problems with booting do not leave any BSOD data, bar the windows Event Viewer one, but Bluescreenview, or similar software do not grab any detail.

Was bios 4.70 for x470 Taichi pulled? I just checked the site today (5/9) and it's not there anymore. I have it on my board with a 5800x no issues at all. https://www.asrock.com/MB/AMD/X470%20Taichi/index.asp#BIOS

Board model: X570M Pro4
BIOS version: 3.50
CPU: Ryzen 5 3600X
RAM: 32Gb (4x8Gb) Crucial Ballistix Sport LT 3000 CL15 @ XMP

Setting: AMD CBS > NBIO Common Options > SMU Common Option > Max Voltage Offset

Setting Description: "Limit maximum CPU voltage for compact coolers, small form factor, or performance tuning."

This setting still does not function on BIOS v3.50. Changing from "Auto" to "100" does not limit max boost voltage at all. The voltage, temperature and benchmark scores stay the same no matter the option chosen.

I tried restoring BIOS defaults before testing it.

2.60 - Setting works with expected voltage, temperature and performance drop.
2.80 - Didn't test
2.90 - Setting is missing
3.00 - Setting does not work
3.40 - Setting does not work
3.50 - Setting does not work

I hope this can eventually be fixed as I find it quite useful. The very top of the boost range is quite inefficient and uses a lot of volts for little performance. This setting constrains the boost slightly, which lowers temperature and fan noise in a small case quite a bit, but doesn't hurt performance that much.

Thanks

on some older BIOS revisions of the x570 Steel Legend, I couldn't do XMP but had to manually set RAM speed and voltage and then it worked fine ..
