Xflash2006 Posted February 9, 2023 Share Posted February 9, 2023 Hi, I have a problem, the turbo boost of my cpu doesn't work, the maximum frequency it should reach is 4.2 GHz, but instead it reaches a maximum of 2.6 GHz. I installed macOS Ventura so I disabled SSDT-PLUG. config.plist Quote Link to comment https://www.insanelymac.com/forum/topic/355617-the-turbo-boost-doesnt-work/ Share on other sites More sharing options...
aben Posted February 9, 2023 Share Posted February 9, 2023 You could try tuning X86PP’s power management data (by adjusting the frequency vectors/Perf Bias for your CPU) with help of CPUFriend. *Recommend to go kext route for data injection.

But my cpu is comet lake and ssdtPRGen.sh doesn't support it.

Xflash2006 Posted February 9, 2023 Author Share Posted February 9, 2023 (edited) I used CpuFriendFriend and it seems to work but now the CPU name is unknown. Is it possible to solve this problem? If I lock the screen the screen won't turn on anymore, is there a way to fix it? config.plist Edited February 9, 2023 by Xflash2006 Quote Link to comment https://www.insanelymac.com/forum/topic/355617-the-turbo-boost-doesnt-work/#findComment-2801158 Share on other sites More sharing options...
aben Posted February 10, 2023 Share Posted February 10, 2023 (edited) AFAIK: With CPUFriend, you should either use the kext approach (CPUFriendDataProvider.kext) OR SSDT for data injection, NOT both; try removing/disabling ssdt_data.aml from your plist and see if that fixes the CPU branding issue. Try the config.plist below config.plist Edited February 10, 2023 by aben Quote Link to comment https://www.insanelymac.com/forum/topic/355617-the-turbo-boost-doesnt-work/#findComment-2801174 Share on other sites More sharing options...

Try the config.plist below config.plist 42.18 kB · 2 downloads Now the CPU name is right. Is it normal for the clock to drop to 2.55 GHz in the stress test? On Windows the clock during the stress test is 2.8 GHz For the black screen problem what can I do?

aben Posted February 11, 2023 Share Posted February 11, 2023 (edited) Those marginal discrepancies between monitoring tools shouldn't matter - what matters is that your CPU should be able to scale to its max turbo frequency dynamically when requested (depending on workloads that demand higher clock speed/peak performance) even on macOS, which I believe is working based off the screenshot you posted. How are you performing the stress test tho? Through the options available via Intel Power Gadget's dropdown-menu? Are you seeing similar results with IPG's "All Thread Frequency" test? As for the black screen issue - not quite sure I can be of much help here as I don't have enough info to identify the actual root cause - too many symptoms to list from. You might want to look into testing other CFL/CML framebuffer profiles as well as fixing sleep/wake issues if any (best recommended to consult Dortania's Post-Install guide). Feel free to test below attached config.plist (for the display issue only) config.plist Edited February 11, 2023 by aben 1 Quote Link to comment https://www.insanelymac.com/forum/topic/355617-the-turbo-boost-doesnt-work/#findComment-2801221 Share on other sites More sharing options...

Is the VRAM normal to be only 1536MB instead of 3.9GB? I attach the screenshot of the All Thread Frequency test.

Xflash2006 Posted February 13, 2023 Author Share Posted February 13, 2023 So is the turbo boost working properly? Quote Link to comment https://www.insanelymac.com/forum/topic/355617-the-turbo-boost-doesnt-work/#findComment-2801319 Share on other sites More sharing options...
aben Posted February 13, 2023 Share Posted February 13, 2023 Yes, it is working as intended. As per the screenshots, macOS is clearly well-aware of the CPU's max. clock capability and will dynamically request/scale to higher freq. as and when the workload/task calls for the CPU to meet its demands (while actively keeping in-check that all other CPU factors are operating within its designed TDP limit (during request by OS) which is why you will not see the CPU peaking to its max freq for any and all stress tests, especially on low-powered CPUs designed for mobile/laptop devices) As for VRAM patching - it is best advised to leave it as-is and allow the driver to allocate natively (which is 1536). In fact, WEG documentation strongly recommends against this patch. Also, good to hear the black screen issue has been solved!
