The iMac DV ClockUp page was originally posted at <http://www.bekkoame.ne.jp/~t-imai/imacde1.html> and is no longer available there. We have adapted that information for the benefit of those who wish to overclock slot-loading iMacs.
This infomation does not confirm stable operation. Please note that any modifications you make to your iMac are made at your own risk.
I analyzed how to increase the clock speed of an iMac DV. If you adjust the set of resistors labeled “R35” to “R42” on the logic board, you may configure the processor clock PLL.
First, remove the display connector cover.
Remove iMac bottom cover (6 screws).
Remove iMac bottom shield (6 screws).
Nonfigure the set of resistors labeled “R35” to “R42” on the logic board.
- S: mount resistor
- x: remove resistor
