Boot Camp Posted April 19, 2008 Share Posted April 19, 2008 I have my Q6600 OC'd to 3.3GHz. I am using a Thermalright 120-Ultra Extreme Cooler. When I try to install stuff or do what ever I am doing I sometimes get a kernel panic and have to restart my computer. But if I lower my CPU's frequency I can install without a kernel panic. Does this mean Leopard is not stable at this frequency? What causes this? Why can some people get up to 3.6 GHz?

JedixJarf Posted April 19, 2008 Share Posted April 19, 2008 Ive had the same problem, had to downclock to fix. Link to comment https://www.insanelymac.com/forum/topic/100193-am-i-getting-kernel-panics-because-of-overclocking/#findComment-715061 Share on other sites More sharing options...
Boot Camp Posted April 19, 2008 Author Share Posted April 19, 2008 Does anyone know if there is a way to make it stable without having to downclock? If some people can get their Q6600 up to 3.6 GHz, why can't I, are there other components involved in these kernel panics other than the CPU?

tazevedo317 Posted April 19, 2008 Share Posted April 19, 2008 i have the same problem. lowering worked for me. but i wish to be able to hit higher speeds.

00diabolic Posted April 19, 2008 Share Posted April 19, 2008 Does anyone know if there is a way to make it stable without having to downclock? If some people can get their Q6600 up to 3.6 GHz, why can't I, are there other components involved in these kernel panics other than the CPU? Yeah bus frequency, memory frequency, memory timings all can affect stability. Try to OC your machine a different way. Try upping maybe your memory first and see if it fails or not. Then slowly try OCing your cpu up little by little till you get stability. The reason some people can OC there CPU higher & remain stable has to do with 3 things. 1. There CPU was made in a country where the standards of production were not as high or supply for the components was short. The supplyer either used parts for the CPU from a higher model or got the parts mixed up and some lower speced CPU's got the ability to be run a lot higher. I would check your stepping and the country it was made in to find out if you got one of those lucky cpu's. I would bet you did not. 2. The mainboard your using. If the motherboard has shotty parts no matter how good your cpu is it wont overclock it even if the options are there in the bios. 3. Ram and other parts of your computer. These parts are all sensitive to an OC especially PCI devices. Try taking some out or disabling in the bios and see what you get for stability. No one reason is the main reason an OC works or does not work. Its many things and you have to be diligent and try them all before you decide its the OS. Most likely its not the OS, but since your on a hackintosh it could be.
