Sorry to cross post, but this is best placed here.
Here's a link to the thread in the G3/G4 forum:

Sorry, my last post on the other thread should have indicated that I placed the solder bridge across the "0" position of PLL #1 to zero it, in order to achieve the 1000MHz configuration (ref: http://www.macxtrem.com/articles.php?article=71)

As a further update, I've just gone through and made all of the PLL switches match exactly those of my 1GHz powerbook. Still no 1GHz for me 🙁
Oh well, it's still working very nicely at 867MHz (confirmed on an OSX 10.4.11 install disc system profiler).

Have you checked the continuity of your solder joins? If might be easier to use conductive ink if you have to go in again, try for 1067Mhz like me 🙂

Have you checked the continuity of your solder joins? If might be easier to use conductive ink if you have to go in again There's only one that needs moving, PLL #1, and yep, she checks out OK with a multimeter on continuity mode, and the resistance across the solder blob is the same as the other pins (near enough to 0-ohms).
Going in isn't too much of a hassle, since it just involves flipping the bottom cover off. I might try some of that conductive ink - perhaps my solder joint is dry.
Did you just blob some solder across the contacts on yours, or did you actually solder 0-ohm resistors in place?

I overclocked mine years ago, I just relocated the resistor to the other space. Fiddly work and vaguely recall it didn't "take" at first either, perhaps heat up the soldering iron a little more to really melt the solder pads you are working on.
