Macpro overclocking tool

June 29, 2008 Leave a comment has released a tool for overclocking the Macpro. It’s not a perfect solution and raises some interesting points about how the Mac keeps time, so read the notes before using, especially on a first generation Intel Macpro.

The more interesting point is that this has been released at all. The PC overclocking field is well established but until now there has been little of interest for overclocking Apple Macs. It’s different in the hackintosh realm, where overclocking the Intel Core 2 Duo/Quad is well documented and common. My own hackintosh has been running an overclocked Core 2 Quad 6600 at 3Ghz (up from the stock 2.4Ghz) for several months. This is set from the Bios and doesn’t appear to have any effect on OSx’s timekeeping ability.

Hackintosh part 7

GaragebandI had a play with Garageband yesterday to test the hackintosh audio input, and I’m happy to report the MIC input is working fine. I made myself a mono ¼ inch to stereo 3.5mm cable and plugged my bass straight into the computer. Nice clean sound, and like many other aspects of this build it just worked. Many forum reports say it’s possible to get the digital output working if you want surround sound, but I’m not concerned with that at the moment.

The other area I started experimenting in was overclocking. From the default 2.4Ghz of the Q6600 I am currently running at a stable 3Ghz using only the Arctic Cooling Freezer 7 Pro. The CPU appears to be multiplier locked at 9x so the only way to increase the speed is to increase the FSB. I have mine at 333Mhz for 9×333=3Ghz. The GA-P35-DS3R bios has an option to automatically control CPU and chipset voltages so I didn’t have to worry about raising these to get the board stable. Read more…
