Reviving a fried Power Mac G4 CPU card

Reviving a fried Power Mac G4 CPU card

Once in a while I take on a project that involves something I’ve never done before. This time it is the revival and overclocking of a Power Mac G4 (MDD) dual 1.25GHz CPU card. This card was working fine until someone decided to take the world’s biggest soldering iron to it in an attempt to overclock it to 1.5GHz. Just like making a sandwich with an excavator, this was doomed to fail. The card fried, pads and traces burned right…

Project Maya – Installing a new CPU

Project Maya – Installing a new CPU

This is a post in the Project Maya series. To see all related posts go to the index page here. While looking for a new CPU card I did some more testing with the fried 1.25Ghz chips. They ran long enough for me to do some basic testing and I ended up removing the internal speaker. This made a surprisingly big difference in the heat output of the power supply as it was now able to draw some fresh air…

Keeping your Mac’s temperatures in check

Keeping your Mac’s temperatures in check

With Macs becoming thinner and components being smaller and more crammed together than ever, you can expect internal temperatures to rise quickly. CPU’s and GPU’s become more energy efficient every year but they still run at the same, or higher, temperatures. Even with the latest CPU’s and GPU’s being far more energy efficient, when a little workload is applied temperatures immediately shoot up. Heat and dust are the primary computer killers (not covering electromigration here), specially when they work together….
