Introdução

Back in 2003 when i was still studying, i bought an used eMac G4 with a 800 MHz processor. After some time with the help of my closest friends Claudio Nizzoli and Vassilis Moutsos we decided to operate on my eMac and we managed to speed it up to 1.33 GHz after 4 years in late '07s together.

Still now days i recall the goosebumps and chills watching my friends trying to scratch of some resistors from the board as i was holding it to achieve the overclock as my eMac costed me 6 months of salary when i was working and studying. It was not a good idea to play with but we surly enjoyed it.

This guide was made in memory of those moments and for all those who still own one and would love to juice out some power of it and it is based on featured guides from iFixit members Arthur Shi, Chris Green and an outsider Leo Bodnar who gave me the idea.

Hope you enjoy it as i did those days. Please feel free to contact me for details or featured corrections.

    • It should be noted that these guides are written based on a late-model eMac (2005, 1.42GHz, DDR). They will differ slightly from the older model eMacs that use PC-133 RAM.

    • Lay the eMac screen-down on a flat surface. I've found it convenient to use a carpeted floor because the computer is so heavy.

    • Remove the single phillips #2 screw on the RAM door, and remove the door

    • The screw is captive in the door, so don't worry about losing it.

  2. Overclocking your eMac, Bottom Screw Removal: passo 2, imagem 1 %32
    • Before starting this process it's important to note that the eMac can have some seriously dangerous voltages inside of it, thanks to the CRT display. Before working on an eMac, you should unplug it, press the power button to clear any stored charge on the motherboard, and then let it sit for 24-hours (or more) to allow the CRT to discharge.

    • You can read more about CRT safety procedures here. If you aren't experienced with working on devices featuring a CRT, it's recommended that you don't proceed any further.

    • On the bottom side of the eMac, remove the following screws:

    • A single 2.5mm hex screw

    • Two #2 phillips screws

  3. Overclocking your eMac, Top and Side Screws: passo 3, imagem 1 %32 Overclocking your eMac, Top and Side Screws: passo 3, imagem 2 %32 Overclocking your eMac, Top and Side Screws: passo 3, imagem 3 %32

    • Now, the shell can almost be separated from the computer.

    • There is a cable that connects to the power button. This must be disconnected before removing the housing completely.

    • Lift the housing enough to allow you to fit your hand through the access door, and disconnect the cable at the power button.

  5. Overclocking your eMac, Shell Removal: passo 5, imagem 1 %32
    • Now the entire shell can be removed from the computer.

    • The motherboard access panel is held on by 4 phillips #2 screws.

    • Remove the screws, then use your fingers to pull on the top tabs to separate the panel from the computer frame.

    • 3-pin fan cable

    • Ground wire, requires phillips #2 screwdriver

    • 2-pin AC cable to power supply

  10. Overclocking your eMac, Assembly Removal: passo 10, imagem 1 %32 Overclocking your eMac, Assembly Removal: passo 10, imagem 2 %32
    • You should now be able to remove the fan assembly.

    • Doing this will expose more of the CRT neck, be careful not to touch this area because it can contain high voltages (and is fragile)

  11. Overclocking your eMac, Bottom Connectors: passo 11, imagem 1 %32
    • There are four connectors at the bottom of the motherboard that must be removed.
