I had the biggest trouble removing those CD-ROM screws...but that aside, how did you manage to solder such small parts? I mean removing them is one thing, if you keep the iron on it long enough, both ends will melt, as long as you don't blow the part...but soldering it on...taping it down is pretty much out of the question for such a small part, and one biggest concern i have is too much solder end up shorting the resistor...any advice? TIA

It's easy to slip with the iron, burn a trace, apply too much heat, etc.
Alternatively, folks have done this mod with "el-cheapo" Radio Shack $15 irons.
I heat one side of the component, using flux at both ends. Heat will travel to both sides of the resistor softening the solder joints and you can lift the "hot" end up slightly, then apply the iron to the other end and it will come off clean . This is a bit dangerous as you could easily lift a pad in the "lifting" process. Some recommend two irons, one at each end.
I use a temp controlled station but I'm certainly no pro in this area so YMMV.
To "hold" the component in place, use a pair of forceps and a light touch. You want to prep the solder area with a bit of solder on the pad so that when you apply heat, it will melt in place quickly.
I recommend using flux, always. The heat/solder flow much more evenly and quickly. Again, I'm no expert so YMMV.
Sometimes it takes a few attempts to get the component straight (since the MOBO is done by machine originally, when soldering manually, "straight" is a relative term <img border="0" title="" alt="[Wink]" src="wink.gif" /> ).
For first-timers, it may look like you soldered with your feet but if it's functional, what the hey...

my experience with those small parts was when i OC'd my TI-85 @_@ only had to remove a relatively big capacitor, if i recall correctly ^_^; i'll probably look at my iBook again when i got my iron back from my gf...

Anybody have an clues as to what symptoms a system might exhibit if it was not able to handle this O/C?
Performed this O/C several months back and (within the past couple months) i've gotten somewhat accustomed to a total system lock-up (no mouse, no crash signs, etc) in both OS 9 and OS 10.1.5 about every other day.
Is instability directly linked to excessive CPU temps? What would be a "safe" temp range i should be looking to stay within?
TIA for any suggestions.

Keep the 100 MHz bus. That's the biggest difference you'll see anyway.

I have yet to see a reliable method of measuring processor temperature - what are you doing? Try setting your machine to 550/100 or 500/100 instead of 600/100 and see if that fixes your problems.

Just wanted to report another successful iBook mod. My friend and I got his old iBook 500/66 successfully up to a 600/100 and so far nothing seems abnormal (except for his MUCh faster system)
Both my friend and I are not engineers and don't have excessive soldering experience ( I'm an IS student, he's in Multimedia), but after playing with the resistors on a small dead ethernet card we felt we could handle the solder job (though our iron was 30W, waaay too hot)
Hats off to Carl and his website for without those step by step instructions we would really have been lost. MacAddict touched on how to do it in a short article but really didn't "show" how to do it, only what to do.
Thanks again Carl!
Cheers!

Thanks for the kind words. We actually did it using instructions from xlr8yourmac, but realized that better (and more detailed) instructions were necessary.
As far as magazines go, there should be some pictures of our iBooks in an upcoming issue of the French edition of MacWorld! One of the editors has been in touch with Stan... I've never been published before..... cool!

well, I'm getting ready to do the OC mod, as well as replace the CD-ROM w/ a Toshiba sd-r2002 combo drive at the same time. Anyway, I'm wondering how everyone's OC'd iBooks are doing w/ Jag. Any problems w/ the upgrade??
Thanks,
Kevin

This is just a post inquiring about who exactly the person in the LA area was who was willing to overclock others' iBooks? Can you e-mail me, please, if you see this? Thanks :o)
