Bregt Posted October 28, 2013 Share Posted October 28, 2013 Hi, I upgraded to 10.9 this weekend. Everything works thanks to the help on this forum. Only problem I have, my OC won't show up anymore. In Mountain Lion this was no problem. I OC'd my Q9550 from 2,85 GHz to 3,9 Ghz and my ram from 800 Mhz to 1102 Mhz (Kingston ram at 1066 Mhz stock) This all worked perfect, but now in 10.9 HWMonitor only shows my stock speed 2,85 Ghz. Speed stepping works however. Also system profiler show my CPU speed as 4,3 GHz Quad-Core Intel Xeon bdmesg gives me this: CPU: Brand String: Intel® Core2 Quad CPU Q9550 @ 2.83GHz CPU: Vendor/Family/ExtFamily: 0x756e6547/0x6/0x0 CPU: Model/ExtModel/Stepping: 0x17/0x1/0xa CPU: MaxCoef/CurrCoef: 0x8/0x48 CPU: MaxDiv/CurrDiv: 0x1/0x1 CPU: TSCFreq: 2833MHz CPU: FSBFreq: 333MHz CPU: CPUFreq: 24167MHz CPU: NoCores/NoThreads: 4/4 CPU: Features: 0x0000025f My Hardware: GA-P35-DS4 Radeon HD 6870 Q9550 Anyone an id how to fix this ?

santa1 Posted October 28, 2013 Share Posted October 28, 2013 same to me My hardware My Hardware: GA-P35-DS3R Radeon NV 9800 GT Q9300 Processor Name: Quad-Core Intel Xeon Processor Speed: 28,6 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache: 6 MB Memory: 16 GB Bus Speed: 1,6 GHz chameleon build 2266 I was on the impresion that chameleon is responsable of detection and injection in kernel for cpu and memory, no ?

Bregt Posted October 28, 2013 Author Share Posted October 28, 2013 I thought so too. I'm also on chameleon build 2266. Is there a way to revert back to an older chameleon build but still being able to boot 10.9? Link to comment Share on other sites More sharing options...
adamsweeting Posted October 28, 2013 Share Posted October 28, 2013 Same here Gents. Even odder = Once I installed Mavericks, I could still see the over clock in About This Mac - but after a few reboots, It's changed. Used to say : 4.2GHz Quad Core Intel Xeon Now says : 3.6GHz Corei7 Link to comment Share on other sites More sharing options...
adamsweeting Posted October 29, 2013 Share Posted October 29, 2013 I've managed to sort it on my rig. I wasn't using an SMBIOS.plist - so I've started to use one! Now I have the SMBIOS.plist in use, I can see "4.2 GHz Quad-Core Intel Xeon" I think these are the pertinent lines: <key>SMmaximalclock</key> <string>4200</string> <key>SMcputype</key> <string>1281</string> Link to comment Share on other sites More sharing options...
santa1 Posted October 29, 2013 Share Posted October 29, 2013 smbios.plist afects only About this Mac window, but system information show 28.6GHz on processor speed Link to comment Share on other sites More sharing options...

wrk73 Posted October 30, 2013 Share Posted October 30, 2013 I think you are using clover bootloader, that are problem. Disable P-state and c-state helped me! Link to comment Share on other sites More sharing options...
santa1 Posted October 31, 2013 Share Posted October 31, 2013 no, this is what i'm using (like i said previuosly) http://www.insanelymac.com/forum/files/file/59-chameleon-22-svn/ Link to comment Share on other sites More sharing options...
Bregt Posted November 3, 2013 Author Share Posted November 3, 2013 I alse tried other version of Chameleon, but that also didn't work. About this mac sometimes does report some other speeds with different versions but HW monitor still reports my 2,83 Ghz instead of 3,9 Ghz. I also tried playing with Chimera, but to no avail. Is this something that can be solved when a new version of Chameleon is released ? Link to comment Share on other sites More sharing options...
