请教关于7950X3D PBO2的问题

我寻思PBO Advanced菜单里也没有直接Enabled这么爽快啊

你要选Advanced才有Curve Optimizer，Enabled只是普通PBO

我的5900x似乎也出同样的问题，PBO Enable了低负载重启，自己调整PBO也低负载重启。
后来搜了一下，看看是不是这个问题：

Ryzen on Linux can lock up due to issues with c-states, and while this should mostly affect 1st gen Ryzen there are reports that 2nd and even 3rd gen can be affected in some cases, make sure bios is up to date, then look for "Power Supply Idle Control" (or similar) and set it to "typical current idle" (or similar).

If there's no such setting in the BIOS try instead to disable C-States globally, also note that there have been some reports that with some boards the setting above is not enough and only completely disabling C-States brings stability.

叫我悠扬

我也是这个U，开了PBO2，跑CPUZ多核15800，单核765。最高功耗135W，再怎么调好像也上不去了。

我知道啊 我的意思 PBO2 enabled 低负载不稳定 算不算体质不行 需要售后

通常PBO2低负载不稳定都是负压降太多，关C-State是自欺欺人没用

X3D就别折腾了没意义

是只把 PBO2 设置为enabled
其余什么都不动  压根没动负压

默认值全是0等于没动还不稳定我只能说还是别玩这个了……
