Ted Cox Posted October 19, 2006 Share Posted October 19, 2006 Hi there, I have an old Northwoord 2.4c running on an ECS PF1. The motherboard and proc should be great overclockers, but the cooling I have on them is junk, so I've been running them stock. However, when I boot into OSX, it shows the processor as 3.06Ghz. I would oridinarily assume that this is just misreporting by the OS, but I have noticed that the machine is unstable and locks up whenever it's been on for a while -- only in OSX mind you, it runs forever in windows without problems (which is kind of a feat in and of itself. ) The machine also has a Radeon 9700 Pro in it with QE and CI enabled. I suppose they could be causing instability as well, but I'm curious if there is any precedent for OSX deciding to overclock the processor? Thanks, Ted Link to comment Share on other sites More sharing options...
equilibriumuk Posted October 19, 2006 Share Posted October 19, 2006 I think it's just OSX. It does it with my systems aswell. p4 2.8c @ 3.5Ghz shows as 3.8Ghz Core2duo e6400 @ 3.2Ghz also seems to show as 3.8Ghz Link to comment Share on other sites More sharing options...
Ted Cox Posted October 19, 2006 Author Share Posted October 19, 2006 ok. Bummer. I was hoping there was a simple way to stabalize the machine. Thanks for the info! Link to comment Share on other sites More sharing options...
wolf103fm Posted October 29, 2006 Share Posted October 29, 2006 10.4.3 reported my P4 (prescott) properly, at 3.0GHz (or 2.99) 10.4.6 reports it as 1.5GHz, it still runs fine though. Would hyperthreading cause it to report as half speed? Link to comment Share on other sites More sharing options...
M Ariff K Posted March 26, 2007 Share Posted March 26, 2007 I'm running P4 2.6c (hyperthreading). Just after installing OSX, Mac Os detects 4GHz Intel with 2GB SDRAM. Damn, I'm using 2 sticks of 1GB DDR400 rams. Why huh? Link to comment Share on other sites More sharing options...
Mousse-T Posted March 26, 2007 Share Posted March 26, 2007 Try this out: Go in the Terminal an type: sysctl -a Is the CPU MHz right? Is your FSB settings right? boot @ F8 : fsb=xxx Or just the System-Profiler tells you something wrong? If, yes, go and install "Colonel System-Profiler Patch" Link to comment Share on other sites More sharing options...
Vipersfate Posted March 26, 2007 Share Posted March 26, 2007 Exactly how would you set the FSB at F8? With many zeros like it is written in the sysctl -a command? Link to comment Share on other sites More sharing options...
