对驱动程序进行编程以降低 i3/i5/i7 CPU 的电压
有一些实用程序可以帮助您undervolt 你的CPU。例如，对于 PC，有 RMClock。对于 Mac，有 Coolbook。
然而，在 Cookbook 网站上，它声明它与 OX X 10.7 Lion 和 i3/i5/i7 处理器不兼容。我有兴趣复制 Coolbook 的功能，它可与 OS X 10.6 Snow Leopard 和 Core 2 Duo 处理器配合使用，但适用于较新的操作系统和 CPU。我真的不知道从哪里开始。据我所知，Coolbook 在 Mac 平台上处于垄断地位，我想知道是否有一种黑客方式可以实现相同的功能？您可以向我指出哪些资源，以便我可以开始了解调整 CPU 电压时驱动程序级别中发生的情况？
There are a few utilities out there that help you undervolt your cpu. For the PC, for example, there is RMClock. For the Mac, there is Coolbook.
On the Cookbook website, however, it states that it is incompatible with OX X 10.7 Lion, and the i3/i5/i7 processors. I am interested in replicating the functionality of Coolbook, which works with OS X 10.6 Snow Leopard, and the Core 2 Duo processors, but for the newer OS and CPUs. I really have no idea where to start. As far as I know, Coolbook holds a monopoly on the Mac platform, and I was wondering if there is even a hackerish way of accomplishing the same functionality? What are some resources that you could point me to so I can begin understanding what is going on in the driver level when adjusting the voltage of a CPU?

问题是，i7 CPU 无法通过软件管理电压。原因很简单。 Intel 已经削减了用于电压管理的外部寄存器地址，只有 AMD cpu 可以通过软件管理电压，或者较旧的 core duo intel cpu。 Coolbook 在旧版 Intel CPU 上的 OSX Lion 上表现较差，但表现不佳，目前没有针对 Lion 的更新。我希望有帮助。
The Problem is, i7 Cpus have no possibility to manage the voltage via software. The reason is simple. Intel has cut the external register address for voltage management, only AMD cpus has the possibility to manage voltage via software, or older core duo intel cpus. Coolbook wors but not very well on OSX Lion on older Intel CPUs, there is no update for Lion at this time. I hope that help.
我在我的 Android 手机上使用过这个。不确定它在 mbp 上如何工作，但它们都是 Linux 环境：
在我的手机上，它会阻止手机使用第二个核心并节省一点电池寿命。希望能帮助扭转局面。只需将 0 替换为 1（您必须是超级用户才能执行此操作）。
I have used this on my Android phones. Not sure how it would work on a mbp but they are both the linux environment:
On my phone it stops the phone from using the second core and saves a little battery life. Hope it helps to reverse it. Just replace the 0 with a 1 (you must be a superuser for this to work).
