Grafdude Posted July 28, 2007 Share Posted July 28, 2007 I've installed coreduotemp and it is reporting that my cpu is running at 1.83ghz, although I have a mbp 2.2ghz. I though it was because I had my energy saver set at normal, but even set at "Better Performance", it's still running at 1.83. Not only that, sometimes I see the clock go down to 1.33 for several seconds (sometimes even minutes) and then it goes back to 1.83. All of this is happening while my mbp is supplied with power (MagSafe Power Adapter) Now, it's to know if coreduotemp really is reporting the correct cpu clock.

Synaesthesia Posted July 28, 2007 Share Posted July 28, 2007 Go to apple menu -> About this mac. I would trust that more than a 3rd party program...

I'm not too hot on my Intels... Link to comment https://www.insanelymac.com/forum/topic/58370-mbp-22ghz-running-at-183ghz/#findComment-416830 Share on other sites More sharing options...
Grafdude Posted July 29, 2007 Author Share Posted July 29, 2007 Under system profiler, the cpu is identified as a core 2 duo 2.2ghz. Link to comment https://www.insanelymac.com/forum/topic/58370-mbp-22ghz-running-at-183ghz/#findComment-416879 Share on other sites More sharing options...
rathalos Posted July 30, 2007 Share Posted July 30, 2007 i know what the problem is... the problem lies with the speedit.kext that was installed as a dependant for coreduotemp... apparently speedit.kext is not coded for the new SR macs and defaults on the older c2d macs which have 1.83Ghz as a base freq for standard models... if u want to do temp monitoring, i reccommend smcfancontrol as it helps u manage ur temp and set ur fan speeds when u see ur temp goes upwards... anyway, pray hard that speedit is coded for SR macs, as i know macs have no in built speedstep capability.. the only speedstep is done by the CPU themself and not controlled by the OS.... (read documentation of speedit and you wil know that apple seriously lacks speedstep, and that explains why mbps run so damn hot compared to all other laptops....)

Stadsport Posted August 6, 2007 Share Posted August 6, 2007 Uh...what. No, no. Grafdude: What's happening is completely normal and even intended. It drops the clock speed when it doesn't need the muscle to keep things running cool and, when on battery power, preserve battery life. Keep CoreDuoTemp open and start encoding a video or something and you'll see it jump up to 2.2ghz.

rathalos Posted August 6, 2007 Share Posted August 6, 2007 stadsport, u're wrong dude.... go to coreduotemp website and check, it has dependencies on speedit.kext... and speedit.kext will detect its max speed wrongly on the new SR mbp which grad and i happen to own... I know this happens cos i actually installed speedit.kext on my mbp and did a sysctl and check it out... if u read the documentation, speedstep is NOT implemented at OS level.... Apple left out speedstep to the chip itself to manage.... no throttle is done by the OS... if u did a sysctl -a with speedit.kext loaded, u will see that kernel.maxcpufreq=2200000 and kernel.mincpufreq=2200000 and kernel.curfreq=2200000... which means that NO throttling is present and apple os does NOT attempt to speedstep itself... but at the bottom, u will notice that speedit.curfreq=1330000 and speedit.maxfreq=1830000... this shows that speedit is reading the wrong max speed from the system... its speedit's fault.... wait for them to code speedit for the new SR mbps....
