已经用的是华硕B550-XE的最新bios2201了，前面几个版本早就显示修复L3的速度问题了，我这个怎么就一直不正常呢，BIOS里就只设置了一个FLCK1933，内存3866。

BIOS里F5全预设后试试呢

这样感觉还是不正常吧

bios恢复出厂预设全默认试下，正常的l3在600g左右，有半速问题的是300g，延迟正常的是12ns左右，你这数据明显不正常

难道怪aida64版本不是最新？

AIDA 6.33.5700测的结果

你这可能是uncroe给的电不够，就是移动端zen3的那个问题
看看电流强设置的是多少

全默认了，DOCP也没有开，AIDA64也是最新版了[img]https://img.nga.178.com/attachments/mon_202104/11/9aQj1u-3plyK1vT3cSif-hq.jpg[/img]

兄弟可以教详细点吗，我是全默认了，啥都没动，之前把防掉压设置了L4也没效果
