#Overclock mac pro tower how to
The operating system has to be able to deal with all kinds of different CPU speeds and know how to handle it. Regarding software and system clock, they are never effected. But I'm comfortable with the current temps and sleep well at night knowing there is plenty of juice to avoid glitching. Then my temps would be a little lower than they are now. Frankly I could probably lower the voltage some, and test again, until I find the lowest possible voltage setting that will run glitch free overnight. I also ran CPU stress tests for 24 and 48 hours which pushed the cpu cores at 100% running various calculations in order to see if it would glitch or not with the speed and voltage settings that I have. All software works perfectly fine and there is definitely a very big difference noticeable in performance. In a couple years I'll be ready for a new computer anyway if it does, but frankly I don't think it will.

Usually I see around 34C as the temperature except under full load then it gets into the 40's. It does run a little hotter than it would without overclocking, but still completely tolerable. The memory speed is also pushed from 667mhz to 900mhz. I have been running it at 3.24ghz for over a year with no problem whatsoever. 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. 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.
