意外发现还保留了当年卡特琳娜的跑分记录, 当时用的型号是
MacBookAir9,1
, 看起来单核能跑4.7GHz对于跑分而言, 意义不大

养老了养老了, 受不了 bugsur, 果断退回Catalina, 本子宛如新生, 香~
PS: 时光机恢复了两遍才恢复成功, 先是用 bigsur 的 recovery 恢复, 结果卡苹果, 万幸重启以后变成 Catalina 的 recovery 了, 忐忑之中又恢复了一把, 搞定

零散tips
- 解锁网卡区域设置: boot-args: brcmfx-country=#a
- igfxonln=1, igfxrpsc=1 两个同时配置boot-args参数会偶发核显满频不降
Intel Power Gadget -> GFX/AVG 5.xx
, 我只保留了igfxrpsc=1
, 据说能稍微提升一点点垃圾核显的性能

散热改造
- 换导热硅脂
传说中的信越7921
, 作用: 增强CPU&GPU散热 - 加装硅脂垫
利民80x40x2mm
, 作用: 及时将热量导出到D面
效果对比:
- 未改造前, R23多核测试第一轮从55W掉到38W, 全程稳定35W+, 核心最高温度100°, C面60°+, D面50°+
- 单换硅脂, R23多核测试第一轮稳定55W, 全程稳定45W+, 核心最高温度98°, C面55°+, D面58°+
- 加装硅脂垫, R23多核测试第一轮稳定56W, 全程稳定48W+, 核心最高温度96°, C面45°+, D面62°+
最终不到一百块的成本(硅脂+硅脂垫), CPU性能释放从官方默认35W提升到48W的水平, 也就是所谓的PL1提升了13W, 而PL2则可以干到56W的水平, 简直超值, 再战三年不是梦...同时因为增强了散热, 跑分/重负载任务一旦结束, 温度会迅速降低到正常水平
