clamshell 366 FW questions - 09/29/05 01:00 AM

I recently picked up a 366mhz clamshell with firewire off of ebay for pretty cheap. it's in great condition for being as old as it is. I popped in a 512MB SODIMM, and was pretty happy with the results. I want MORE laugh . i found several guides to overclocking the rev A ibooks (300mhz), so i popped open the case (not as hard as some make it out to be), and got down the to logic board and much to my dismay the board is different than the ones shown in the overclocking guides. its a ppc750cx processor. anyone know if i could oc this computer and how? i'd really appreciate it.

Yes, it can be overclocked. Nice buy, by the way. Those are sturdy books that last. There are several mac overclocking sites out there. Try Google. I will check the ones I know of and get back to you (im at work now).

i've tried googling, but i'm pretty much a mac newbie so i kept getting crap results. thanks a bunch

Give those little brats a whack for me! wink



As for the clam...

Yeah, you can overclock it. However, if you intend for it to stay a stable laptop, you won't be able to boost it like you will a desktop (for obvious cooling reasons). I'll be interested to see how far you can jack it before you start melting plastic.

As to [i}how[/i], I'll have to get back to you on that. I'm supposed to be doing work right now... whistle

Later this afternoon I will post some links for you. Did you try the links on this site?
He is write, dont go to far-I think I would be happy with 400mhz. Remember too that you will be sucking up more batteries. Make sure you weigh the +s and -s before you decide to do it.

yes i've tried all the links i can find. they are all for the original non-firewire ibook. the logic board in my ibook is extremely different from the one in the pictures in those links. i think the fact that it has a 750cx-e instead of the 750cx has a lot to do with that...

did anyone happen to find any more info? i'm thinking of tearing it down again and experimenting...if i blow the logic board i'll just get a 466 logic board wink

I am looking to figure this out as well. I also have a 366 mhz ibook and really want to overclock it, has anyone figured it out? I have looked at the board and believe that the area for resistor movement is in the area of resistors marked R59 - R66.

i just added some better heatsinks to the video chip and the 2 main chips...i'm going to start looking into the oc'ing as soon as i pick up a spare logic board wink

I have been searching and searching for a picture of a 466 clamshell logic board because I figure that would have the right resistor configuration for us to use. But I cannot find a good photo, does anyone else know of a good photo?

Re:clamshell 366 FW questions - 10/24/05 07:09 AM

good idea...compare the two and match them...any volunteers? and yeah, i looked at my logic board the other day after reading what you said, and that area is probably where the PLL config is set

Maybe this will help?

Also, I bet you can easily get a stable 433mhz out of that iBook B)

Been there, wrong iBook (different processor). I would love to get 433 out of it, if not 466... hehe. just waiting to get my hands on an ibook 466 logicboard.

I found the following info during a day-long search for another topic just by chance...I'm going to try it out tonight and I'll post the results

did it...seems to run faster, but nothing will confirm clock speed. system profiler and about this mac show the original speed, but there is a noticable increase in speed. according to the instructions i should be running at about 450mhz with a 82mhz bus speed....

theres the comparison of my two xbench scores before and after overclocking...my overclocked score compares very well with the 466mhz machines....especially considering that the 40gb drive that i swapped in from my brand new ibook g4 is considerably slower than the 60gb drive i had in the clamshell before overclocking

careful with that bus speed increase, they usually spell disaster.

yes, 66 to 82 is quite a jump. no problems so far B) . the thing i was concered about the most was the ram, but theres no noticeable problems...i booted to a kubuntu live cd and went through the motions there and I couldnt make it break smile

I wouldn't be too worried about the bus speed increase, original white iBook owners have been increasing their 66mhz bus to 100mhz for awhile. smile I can't wait to try this on my indigo iBook.
