I heard from some people that these settings can help:
"1) DRAM voltage: 1.35v, increase +0.01V until stable
2) DRAM Boot (bottom setting in DIgi+ menu): 1.35v.
3) Raise SOC: ~1.1v, maximum: 1.2v
4) VTTDDR (first setting in Tweaker's Paradise): 0.80520, raise +0.01 until stable
5) Use DDR4-2933 or DDR4-3200 setting.
6) Set timing settings: 16-18-18-36
