我粒7800x3d pbo2 curve optimizer -15 all core 最高得1.13v

，好懶ram 開expo 6000mhz cl30 1.35v

，啱啱先砌好自組水冷

未找到真原因前. 我手動set返SOC 同 IO 電壓去返1.1V. 暫時一樣咁stable. 手動set RAM真係好煩..

Interesting bit from the comments section (deepl translated)

I was able to reproduce the problem with me. It is due to the EXPO parameters that AMD specifies. Asus and Gigabyte have implemented these 1:1 without paying attention to the new X3d CCD. While "X" cpus tolerate higher voltages, the X3D die off one after the other because they are much more sensitive.

As soon as Expo is enabled, the CPU SOC and CPU VDDIO/MC voltages increase to 1.36-1.4, sometimes boosting to 1.5V in Windows, causing instant death on the X3d. If you set all voltages manually to the correct values, there are no problems.
