On my 4GHz iMac 5K (late 2015), I immediately saw my CPU frequency bouncing around between 3 and 4GHz, making my life that little bit more complete. When it comes back up, you’ll find the new CPU frequency line as shown in the first screenshot. I didn’t get a screenshot when I installed it, but it will appear in the area indicated in the screenshot. After you install it, however, you also need to OK it in System Preferences > Security & Privacy. The first thing you need to do to enable CPU frequency monitoring on your Mac is to download the Intel Power Gadget and install it. Enabling iStat Menus CPU Frequency Monitoring I’m in that camp, and if you’re reading this, you probably are, too. but I’m focusing on iStat Menus with this piece.įor the vast majority of users, there’s little need to enable CPU frequency monitoring unless you just want to. There are all kinds of things you can do with it. If you wish to access the default install directory of Intel Power Gadget, you can access it via: \Program Files\Intel\Power Gadget 3.5 Known Limitations and Issues It’s also worth noting that there are some limitations and issues when using the Intel Power Gadget caused by the type of hardware you have. The Intel Power Gadget is software that sits deep in macOS (or Windows and Linux) to report on everything your CPU is doing. Apple takes advantage of this with Macs (and iOS devices, but that’s a separate topic) in order to save power and reduce heat. Modern CPUs vary their frequency according to their device’s needs at the moment. iStat Menus CPU Frequency Monitoring Intel CPU Frequency Monitoring The Windows version of Intel Power Gadget does not show any trace on this machine either. There are a couple of steps you have to take to do it, but they’re easy. I have created a brand new Windows VM running the same build with no additional software installed and this does not exhibit the same problem (the clocks correctly step down when idle).Bjango’s iStat Menus can take advantage of Intel software that can monitor your CPU frequency. As soon as the task is complete and the temperatures drop a little, the clock frequencies return to full Turbo Boost of 3.4 Ghz.Įssentially, the CPU throttles as soon as I try to do anything on the VM and my machine constantly runs hot. Task Manager in Windows will report up to 100% CPU utilisation, Activity monitor up to 400% for the VM and, strangely, IPG rarely exceeds a utilisation of 30%. building a solution in Visual Studio, although something like opening Outlook achieves a similar response) CPU temperatures quickly hit the max 105 degrees and the clock frequencies as reported by IPG start throttling back to prevent heat damage. As soon as I perform any task on the VM that increases CPU usage (e.g. 3 hours ago, Zodiark1593 said: Can't pin the blame on Intel for this at all. When the VM is active but idle (a minute or two after startup, around 5-10% cpu displayed in Windows Task Manager) IPG reports temperatures in the 80-90 degree range and with CPU utilisation of 5-10%, Activity Monitor reports CPU percentage of around 50% for the VM. And if you don't have hard TDP limits, you should at least give the maker of the machine or better the user the ability to fine tune the power consumption a bit and allow either a more safe/conservative setting and the shit what we have right now. When I switch the VM on, the clock frequencies immediately turbo boost to the maximum 3.4 Ghz and remain there for the duration that the VM is active. With the VM switched off IPG reports CPU temperatures in the 50-70 degrees (C) range and CPU clock frequencies scale up and down depending on demand as I use the machine as expected. I am monitoring CPU usage and temperatures using Activity Monitor and Intel Power Gadget (IPG). I'm running a Windows 10 VM (1803 build 17134.191) in Parallels 13 Pro on a mid-2012 retina MacBook Pro (2.6 GHz Intel Core i7).
