After prolonged testing, I have to say that it's still not right. The sound crackles in the games. When watching youtube, the sound is fine. During gaming, the computer sometimes restarts. VDDCR_SOC Voltage is always set to fixed. So we have another scum in line.

some have reported that Corsair RAM needs extra voltage above 1.35v to run XMP stable

How did you add your RIG in your firm? I can't find where can I modify my Profile, neither I can find a button to edit my posts, that's why I have to make a new one to ask you about this extra stuff. Thanxs in advance!

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 ..

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
