Of course the best course of action is to restart before using any utility like this, and do your testing on a drive other than your normal boot drive that you use for regular work and use. It is also possible for the journal to become corrupt and need to turn off, then turn it back on (booted from another drive) to get it back to working. I don't consider OS X filesystem to be all that robust, nor does Disk Utility look to see all the possible problems, which is why you still must use 3rd party tools (MicroMat, Alsoft, etc). My directory had some orphan files and needed to be repaired with both Disk Utility and Disk Warrior. Probably should have restarted the Finder or done a sync command to flush changes to files and directory before running. No other programs were loaded or running except System Profile (I wanted to watch for memory or parity errors). In fact, I had cloned my system, run DW etc all in getting prepped for 10.5.4. I was surprised because I had a clean system and had run DU and Disk Warrior earlier, and had not had any problems (for months, since last fresh install). Since HFS+ is a pretty robust filesystem, it recovers well at the next reboot. *Are there any risks involved in overclocking by a great deal?*Īs with any system crash, you lose unsaved files. Here is the article and download to the utility: Carefree overclocking fun does not exist beyond this frequency.+

But a reboot without crashing is only possible up to 3178 MHz. The latest series of the Mac Pro (Mac Pro 3.1) can indeed be overclocked in the ZDNet test up to 3241 MHz while remaining stable. ZDNet Clock is fundamentally "reboot-proof". +The only option for "normalising" the time of the Mac Pro again is to restart without switching off the computer. So videos do not run faster after overclocking.+ After all, multimedia applications use the HPET module.

+Whereas programmers of the IBM PC XT had to be forgiven for using the bus clock speed because of inadequacies of its Intel 8253 timer module, it should be reasonable to expect more from Apple, who now only offer computers with modern HPET timers.

Nor does time correction by means of the Mac OS NTP daemon succeed: It simply no longer works with a large discrepancy between the bus clock and real time.+ It is compared with real time when booting up. +Unlike Windows, Linux and many Hackintosh versions, Mac OS uses the bus clock speed as the time source. One caveat - no performance improvement in Xbench (or other benchmarks) but the article seems to address this and suggests a stop watch to see the real-world performance gains since the Mac clock is tied to the system clock. I've downloaded the app and will post results as soon as I can. Well, they claim you can OC a 2.8GHz mac pro to 3.2GHz safely using this utility.
