Its late, thats says a lot, and i got to thinking if there was anyway to overclock my 333Mhz chip in my iMac. Just a crazy thought

Sounds like a good idea to me, not crazy!!!

[Ca$h68]

Yeah, you can do that. Thats my next project, but first I'm swapping my 333 with another 333 (in yet another iMac) because it runs 40 degrees cooler, thus easier to O/C. I should try that next week sometime. I'll let you know, but I do know that some 333 can go to 400.. some 450?

You can certainly chip it a bit more but since the 1st gen A-D all still have the 66mhz bus, as the ratio increases so does the bottleneck. I'm not sure how much faster Powerlogix or whatever will let you up the backside cache speed either. But hell, damn the torpedos, full steam ahead.

Cash, after having some free time and reading about your copper/aluminum fiasco i found out that my chipis aluminum....bummer. Can I Still overclock it without killing my precious iMac? Hope you get back with some info.

Yeah, you can. But check how hot it runs right now with that powerlogix cache controller.. (available from powerlogix.com)... this will tell you how hot you run NORMALLy.... lower teh temperature the better... so.. yeah, you can o/c it if it is a cool running aluminum chip, it just happened that my aluminum sack ran SUPER hot, hotter than ANYONE else's.. (I think)... so, now it runs 40 degrees cooler, which is awesome... well.. once it gets fixed. Hehe. But yeah, if it is running hot, it could still work, you just need more cooling.

PS: Hope that helped somewhat.

Well my iMac runs between 116-123F, 116 when just sitting there on, 123 when playing MP3s and such. I am guessing this is pretty hot but i'd still like to know of my overclocking abilities (I'm new to this sort of thing). thanks ahead of time for any info

Thats not that hot. Thats somewhat normal. My old aluminum chip ran at 146-150 degrees. Blech.

Ca$h

[sek929]

All this heat talk gets me to think that chips should be water cooled like Porsches not air cooled like Yugos.
Maybe if i rigged a small refrigerator under my computer desk and piped the cold air into my iMac... .eh nevermind, jusy keep the info coming Ca$h (123F not hot? well i'll be) or if you like (or if you don't, whatever) you can email me. [address below]

actually, porsches ARE air cooled. Kinda funny since you used those as an example. HEh.

Ca$h

[sek929]

My bad, i was refering to old Porsches (like 4 years ago) were still water cooled, while the new ones (Boxster, etc) are air cooled.
Not that this matters to overclocking an iMac

Porsches have been air cooled for a LONG time... thats why they have those big vents in front of the rear wheels. I havent ever heard of a watercooled porsche before... >shrugs<

Ca$h

[sek929]

Not that this matters,but you have probably seen old Porsche Turbos where those air vents near the rear wheels were used to feed the massive twin turbochrgers. But i think late 80's and even some early 90's Porsches were still using water cooled engines. But i may be wrong...anywho about them overclocked iMacs eh?

Hey, about the Porsches--

They were ALL air-cooled up until the new 911 (or 996, whatever you wish to call it), when Porsche started to use water-cooling (more efficient). Every car the Porshce currently manufactures (Boxster, all the 911's and 911 Turbos) and their upcoming SUV are all water-cooled.

Hope that clears up that dilemma.

As for overclocking iMac's? I have no idea...

AHH!!! yes i am an idiot, i knew that, all there old cars are air cooled while their new ones are all water cooled. But who cares Cash, just let me tap into your vast knowledge of the iMac

Wait.... PORSCHE IS MAKING A F-IN SUV?!?!?!

AAAHHHHHHHHHHH!!!!!!!

Screw this, I'm selling my iMac, buying a gun, and shooting myself in the head.

Ca$h

[sek929]

Yep and Lamborgini is going to be making one around 2004 or so (with the V-12 Diablo engine) and i have to say, what is the point? Use money to buy SUV and buY a sports car instead, faster,better handling, better gas mileage...

I get back to my original question, how can I overclock my iMac? When is this info supposed to come Cash? Or are you still stuck with the smushed daughtercard?

sorry. Um. You cant do it personally, you need to have some resistors moved. Here:http://home.earthlink.net/~nickndan/imac/imacmod1.html

Go read that.

Andy my puter is better now.

Hello people!

Feathers mentioned that we were stuck with the 66 Mhz bus on rev. A-D iMac, thus the "moving the bottleneck around".
Can't we do anything about that? I mean, we've got rev. A iMacs running at 500 Mhz (Powerlogix), Voodoo 2 cards, CD-Rs, EXTERNAL IDE drives (long ribbon cable), lights in the mouse, in the keyboard and God knows where else, and we can't do a simple bus speed overclock like PC users?
Man, and I thought we were all that...

Voodoo2s arent that great. I want a PCI voodoo5 for it, but Im pretty sure I'd have to use another monitor.

Ca$h

[TimmyDee51]

Yeah, if I could overclock my bus speed, I would be in a lot better shape. I don't want to buy an upgrade card and then have it sitting comparatively idle while my stupid 66 MHz bus slows the whole thing down. Isn't there any way?

[Ca$h68]

I think we should all get faster processors first, then worry about this.
