stingray_454 Posted July 21, 2014 Share Posted July 21, 2014 Hi, I have a 3.5GHz 4770k haswell CPU in my hackintosh, and everything is working great with 10.10 Yosemite. I tried overclocking the CPU in bios to 4.5Ghz. Booted into windows and ran som tests, cpu speed and stability seems to be ok. After that I booted into OS X, but clover says my CPU speed is still 3.5 GHz. I tried with both "CStates" and "PStates" off and on, but no difference. In the boot menu under CPU, it reports the CPU speed as 3.5 even though it's set higher in BIOS. So, my question is, why does this happen, and what do I need to change to keep my BIOS set overclock when booting with clover? Quote Link to comment Share on other sites More sharing options...
Maniac10 Posted July 21, 2014 Share Posted July 21, 2014 Depending on how you overclocked the CPU the new speed may not be reflected on "System Information" but it should be in Clover's boot.log. For example I only changed my turbo multipliers so the CPU min-max speeds are left unchanged: 3:991 0:000 BrandString = Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz 3:991 0:000 FSBFrequency=129MHz 3:991 0:000 Corrected FSBFrequency=100MHz 3:991 0:000 MaxDiv/MinDiv: 34.0/16 - normal multipliers 3:991 0:000 Turbo: 44/44/45/45 - turbo custom multipliers 3:991 0:000 Features: 0xBFEBFBFF 3:991 0:000 Threads: 8 3:991 0:000 Cores: 4 3:991 0:000 FSB: 100 MHz 3:991 0:000 CPU: 4400 MHz 3:991 0:000 TSC: 4400 MHz 3:991 0:000 PIS: 400 MHz 4:209 0:000 Calibrated TSC frequency =3410019343 =3410MHz 11:699 0:000 Finally: Bus=100294kHz CPU=3410MHz As you can see the final CPU frequency is 3410MHz which is the original max frequency (non turbo) of my CPU, but it also detects my custom turbo multipliers correctly. 3 Quote Link to comment Share on other sites More sharing options...
stingray_454 Posted July 22, 2014 Author Share Posted July 22, 2014 Thanks for your reply! I checked the boot.log, which looks like this: 1:531 0:000 CPU Vendor = 756E6547 Model=306C3 1:531 0:000 The CPU supported turbo 1:531 0:000 BrandString = Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz 1:531 0:000 MSR 0xE2 before patch 18000402 1:531 0:000 MSR 0xE4 00001814 1:531 0:000 MSR 0xCE 00080838_F3012300 1:531 0:000 non-usable FLEX_RATIO = F0000 1:531 0:000 corrected FLEX_RATIO = E0000 1:531 0:000 FSBFrequency=128MHz 1:531 0:000 Corrected FSBFrequency=100MHz 1:531 0:000 Vendor/Model/Stepping: 0x756E6547/0x3C/0x3 1:531 0:000 Family/ExtFamily: 0x6/0x0 1:531 0:000 MaxDiv/MinDiv: 35.0/8 1:531 0:000 Turbo: 45/45/45/45 1:531 0:000 Features: 0xBFEBFBFF 1:531 0:000 Threads: 8 1:531 0:000 Cores: 4 1:531 0:000 FSB: 100 MHz 1:531 0:000 CPU: 4500 MHz 1:531 0:000 TSC: 4500 MHz 1:531 0:000 PIS: 400 MHz It seems to have the correct clock, it's only the "About this mac" and "System information" that displays the base speed (just confirmed this by benchmarks as well). Is there any way to set those values to reflect the true speed of the CPU? Quote Link to comment Share on other sites More sharing options...

stingray_454 Posted July 22, 2014 Author Share Posted July 22, 2014 Thanx Allan, I'll use that to make some changes . Just out of curiosity - when I previously used Chameleon and overclocked in the same way (I have selected one of the OC profiles in the bios, I didn't change any clocks / volateges manually), the information was updated properly, but it's not in Clover. Is this a missing feature in Clover? No big deal as it's only cosmetic, just wondering if there's a way to make the about-info read the actual speed instead of setting a static text.

Maniac10 Posted July 22, 2014 Share Posted July 22, 2014 Clover tries to respect the Mac way when possible so it shows the regular max speed and not the turbo one, just like a real Mac. You'll have to do it manually like Allan suggested if you want that reflected on those apps. EDIT: be careful with "FrequencyMHz" cause it actually affects the CPU performance, it's not only cosmetic. Besides it will probably be deprecated soon as it's quite harmful and the automatic detection has been working perfectly for a while now. 1 Quote Link to comment Share on other sites More sharing options...
xenophex Posted July 26, 2015 Share Posted July 26, 2015 Least on my Asus X99 Deluxe I had to flip the TPU switch to II, and bang it got the ratio boosts. Quote Link to comment Share on other sites More sharing options...
