This is indirect, but will let me know if the SMC is CPU throttling me. 300% Kernel_task + 80% CPU throttling is obvious when you can see the frequency "0.8 GHZ" in IPG.Īny ideas - directly or indirectly - on how to check the actual CPU frequency? They are running Yosemite.Įdit: While thinking about this further, I'm going to try booting it into SMC bypass mode and re-running geekbench to see if the scores change. My previous project with an 2013 iMac revealed the double-throttling nature of the SMC (CPU throttle + excessive kernel_task activity), but I was able to easily check the CPU status with IPG. I can infer I am getting throttled by seeing Geekbench 4 readings about 30-40% lower than the scores posted (1200/2000 CPU geek bench 4 score for my 2.53 Late 2008 MBP model currently) - and the temperature stays cooler than I expect under "100%" load. I can easily check the kernel_task, and see the CPU load in Activity Monitor, but finding the actual working frequency is elusive (not the number stated in About this Mac). SMC throttling can involve both kernel_task AND lower CPU frequency. I need to know if I am getting SMC throttled. All utilities (iStat menus, for example) depend on IPG for the **actual** frequency data, so no 3rd party "system monitoring" apps are useful at all. ![]() installing IPG manually out of it's package crashes the computer on app launch. they are first generation Core processors, and are not supported by Intel Power Gadget (IPG). I'm working on a mashup project with older MacBooks / MacBook Pros - Late 2008 models (the first unibody ones).
