ZDNet Clock ist ein Overclocking-Tool für Macintosh Computer. Die Version 1.0 unterstützt die Modelle Mac Pro und Xserve. Typische Geschwindigkeitssteigerungen liegen bei 15 bis 20 Prozent. Mittels eines Schiebereglers lässt sich die gewünschte CPU-Frequenz auswählen. Rechner mit einer 2,8-GHz-CPU können meist bis weit über 3,2 GHz getaktet werden.
Description:ZDNet Clock is an overclocking utility for Macintosh computers. Version 1.0 supports Mac Pro and Xserve computers. Typical increase of speed ranges from 15 to 20 percent. Simply select the desired CPU frequency. Most computers with a 2.8 GHz CPU can be overclocked to 3.2 GHz and up.
Summary:ZDNet Clock is the first overclocking utility available for Mac Pro and Xserve computers. Overclocking no longer is a Windows-Only domain. Unlike most overclocking tools for Windows ZDNet clock can be used without any hardcore knowledge. ZDNet.de features detailed coverage of ZDNet clock in English and German.
Ist jemanden außer diesem Placebo-Tool eins bekannt was auch wirklichübertaktet Auf einem Mac Pro 2.1 läuft es hier gar nicht ( weil man lautRequester einen Mac Pro dafür braucht ) und auf einem 1.1 läuft eszwar aber es ist halt ein reines Placebotool denn:
Laut Tool angeblich von 2.66GHz auf 3GHz übertaktet ( das Tool merkt sichbeim Beenden und Neustart des Tools sogar den Pseudotakt ) aber:1. In Benchmarks keinerlei Unterschiede2. Gleichbleibende CPU-Temp3. OS X sowie alle anderen Analysetools zeigen weiterhin 2.66GHz ab
Ever since Apple shifted the Mac line to Intel processors, its computers have been getting more and more PC-like in their capabilities. First up was Boot Camp, which lets you run Windows (or Linux) on Mac hardware. Now it's the turn of the overclockers: ZDNet has release a software overclocker for the Mac, called simply ZDNet Clock.
ZDNet.de has posted a new tool called ZDNet Clock Tool 1.0 for Mac Pro which allows you to overclock your Mac Pro. The process of overclocking uses software to increase your computer's processor speed and bus speed, potentially leading to higher performance. Boost the speed too high, however, and the computer may crash as either the processor or some of their components are unable to keep up. Still, ZDNet.de claims to have achieved some impressive results:
Rebooting (but not shutting down) reportedly corrects this timing issue on all but the 1st generation Mac Pros. More details are available in the article. The application is available for free download from ZDNet.de (click on \"Jetzt herunterlade\" to download). Some MacRumors readers have already had some experience with this tool, but readers should proceed with caution (see potential disadvantages in overclocking, in general).
ZDNet Clock is developed by de.zdnet and is used by 6 users of Mac Informer. The most popular version of this product among our users is 1.0. The product will soon be reviewed by our informers.
Proven to work by those in the Mac community, the approach also increases the speed of the system bus and the memory as a result, though Apple's choice of hardware ironically suits it better to the process than many gaming-oriented parts for Windows computers: as the Mac Pro must use RAM with error correction, it prevents an excessive overclock from ruining data on the hard drive by making sure that only valid data leaves system memory.
The clock difference is enough to provide a tangible \"free\" upgrade in performance to the systems, though this isn't always measurable. In synthetic tests such as Geekbench, the software can incorrectly report similar performance even though timing the results proves that they're above what would happen at Apple's officially rated clock speeds.
However, unlike most overclocks, the technique requires a certain degree of trickery and carries an extra amount of risk. The current version of the tool works by loading a kernel extension into Mac OS X on boot that forces the clock speeds upwards immediately after the system starts. Without it, the Mac Pro would immediately revert back to its stock speeds the moment the system is rebooted, according to ZDNet. The initial beta app can also sometimes be overridden when the Mac comes out of sleep mode.
Like most overclocking, the technique is also limited by the nature of the hardware. At present, the German experimenters are unable to push past the 3.24GHz barrier without an inherently unreliable system. The faster processor speeds eventually overwhelm the memory and prevent it from correcting every error, triggering a kernel panic in Mac OS X that forces a reboot. High-performance third-party memory that operates above spec is described as the only real solution to this problem.
System time also falls out of sync without the expected clock rates and can't be corrected even by calibrating the computer online, the testers say. Instead, a reboot is necessary to at least temporarily provide accurate timekeeping.

Quote:Originally Posted by AppleInsider The current version of the tool works by loading a kernel extension into Mac OS X on boot that forces the clock speeds upwards immediately after the system starts.Let me just add some comments:ZDNet Clock doesn't load a kext at boot time. It is dynamically loaded, when you start ZDNet Clock. After a reboot the kext will never be loaded, until you run ZDNet Clock again. This keeps things safe.If you reboot without turning the system off (shutdown), the Mac Pro keeps the speed you set with ZDNet Clock. In this case the system time runs at the correct speed and benchmarks report better results, because Mac OS adjusts the system time speed at boot time, but at no time afterwards. Also, the kext is not loaded, because it is needed only to change the bus clock. Once changed the kext can be unloaded.If you shutdown your computer and turn it on again later it will always run at stock speed. You need to run ZDNet Clock again.With pre-installed Apple RAM we were able to run a 2,8 GHz Mac Pro at 3,17 GHz 24 hours under full CPU and memory load without a single parity error, that had to be corrected.Using Kingston or Transcend RAM the same results could be achived at 3,24 GHz. Same specs as Apple RAM.Some noname RAM showed up errors at 2,83 GHz. A user reported RAM errors at 2,86 GHz using noname modules. One should probably check for parity errors in the system log when using noname RAM, even if the system runs at stock speed.-Christoph (Author of ZDNet Clock)
Mac OS X only: Freeware application ZDNet Clock overclocks your Mac Pro's processor for faster performance. As the name suggests, the application is made by the German branch of tech web site ZDNet, and according to the download page the latest generation Mac Pro (3.1) with a 2.8GHz processor can be overclocked to 3.24GHz without increasing voltage to the CPU and without losing stability (translation: faster computer, no major risk). Overclocking has never been as easy on Macs as PCs, but the ZDNet Clock tool aims to make it just that. ZDNet Clock only works on Intel Mac Pros and the Apple server Xserve, requires OS X 10.5. We don't have a Mac Pro at Lifehacker HQ to test it on, so if you feel like being our canary in the coalmine, let's hear how it worked for you in the comments.
The latest version of ZDNet Clock is 1.0 on Mac Informer. It is a perfect match for the General category. The app is developed by de.zdnet. Jun 27, 2008 +The only option for 'normalising' the time of the Mac Pro again is to restart without switching off the computer. ZDNet Clock is fundamentally 'reboot-proof'. But there are a few snags. 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.
Whereas there are a lot of tools available for overclocking in Windows, it is a fruitless task looking for similar applications for Mac OS X. This has all changed now. The ZDNet Clock tool for Mac Pro raises the frequency of the processor, FSB and memory.
Apple owners can do a lot of things better with their computers than Windows users can. Despite this, there are a few things that are easier to implement under Windows. These used to include overclocking. Many PCs can be overclocked in the BIOS set-up, although this does not apply to most brand name machines, such as those from Dell, HP or IBM. Under Windows, however, overclocking tools such as Clockgen, SysTool or CrystalCPUID can be used.
Underclocken fuers MacBookAuch wuenchenswert waere die Moeglichkeit einen Processor zu underclocken. Die MacBook Pros naemlich laufen sehr warm (deshalb auch sehr laut) unter voller Belastung. Optimal waere wenn der underclockte Rechner eine grosse Aufgabe langsam waehrend der Nacht bearbeiten koennte, ohne dass der Ventilator sich kaputt spinnt.
Bad Ram=Bad OverclockingAs mentioned in the article, oc depends on the memory-modules. A lot of users do have problems with RAM from OCW when they try to overclock their Mac pro. Apple-Ram is ok for oc. Modules from Transcend and Kingston are even better.
Mac Pro 3.2 Overclocked at 3.6 working perfect!I overclocked my mac pro 2008 generation at 3.6 and works perfect. I will keep trying more, but my question is how to keep the computer overclocked after shoot it down. I mean, do I have to overclock the computer after each time that I turn it off There is any way to make a permanent overclockAny way,Thanks for this tool! 153554b96e
