![]() I have a Core2Quad Q6600 cpu in one PC, that CPU is officially rated as being 2.4ghz, quad core. But there are moderate overclocking gains that can be made without any fancy cooling systems other than perhaps a larger CPU fan(which is generally going to be quieter too). Pushing more voltage into them will stabilize them and allow even higher speeds, but then the temperatures start to really go up and fancy cooling systems are needed. Some CPU's are known for having tremendous overclocking capability before they become unstable. As you push the CPU faster and faster, and also push the memory speed along with it, it can eventually get unstable. The BIOS on PC is where you can establish the parameters that dictate how fast the cpu will run and how much voltage you will ram down its throat so that it can do so without glitching. That being said, Macs don't really have the same kinds of overclocking capabilities as PC's because they do not have BIOS like all PC's do. UPDATED : two years later, why not try and see if anyone has an answer? Was it ever clear how this worked and why could(n't) it work today on 10.Overclocking (PC's) in general is not dangerous if done properly and should have absolutely no adverse effect on your software or system clock, regardless of how complicated your software is. ![]() UPDATED : still no love on this question, so changed it to at least asking if source code is available. Of course, if it worked fine the first time why bother updating it? The only problem is that it is a 32-bit kernel extension and the last version of OS X to support this KExt was 10.7 Lion.ĭoes anyone know if this tool was ever updated? I'm surprised I really don't see any information on how it is working, but I would hope that someone would have updated it for the modern 64-bit kernel versions? At least if the source was released, someone who has some spare time could pick this one up.Īlternatively, has anyone ever seen a way to overclock a 2008 Mac Pro that works in 10.9 or 10.10? I know I could replace my processors or upgrade, but I think I've got a few years left in this rig. ![]() Though the pages still exist on the web, it seems that after "ZDNet Clock 1.0" was released it was never touched again. That being said, there was a kernel extension released by ZDNet back in 2008 that allowed you to overclock this specific machine. Yes, they've made faster machines, but this old one still holds its own well enough. The Mac Pro from 2008 (MacPro3,1) is still a fairly relevant machine in the modern OS X as not only does it run the latest releases of OSX, but also the 8 CPU cores that it came with provide enough power to do all but the most demanding tasks. ![]()
