Hello, a new user here also introducing my orange iMac G3 400mhz I bought the other day. It is in awesome shape and was stored safely for 7 years. Cost me $35 for everything a few days ago. It seems this is the best place for information on more modern macs so I come with a question. Will a 500Mhz processor work in this model? 100 more Mhz would be :cool: . Already upgraded the memory and hard disk. Would love a G4 upgrade but those are probably beyond my reach.

A 500mhz, 600mhz, and 700mhz logic board will work in that model. The only way to upgrade those to a G4 was by sending it off to a company to have a new one soldered to the board. The company no longer does this and finding one with a G4 is very rare as the upgrade was very expensive.

thanks for the info. I only see a few on ebay, the highest is a 600mhz. It is tempting... but I will wait for a 700mhz.

What do you mean by modern? this Mac is 10-11 years old.

Good luck and lots of fun with your new old Mac, though!

Cox, I think that this is the point - more modern than iMac G3 ;)

OP: if you'll get 600 MHz logic board and you have soldering skills on a good level, it's simple to overclock it to 700. You'll gain 16MB graphics and 300 MHz extra CPU juice ;) I have snow 600 OC'ed to 700 and it runs fine for over a year.

:) well I wanted to imply the question, whether he had actually planned to buy a modern Mac, but was not aware the iMac G3 is that old. Though I love iMac G3s and have one myself, I'd recommend selling it and getting a PowerMac G4 with better CPU and for the same price (at least on Ebay Germany they go for the same prices, normally).

Oh! I wasn't really clear about coming here for information on modern macs I guess. Although I do have an Xserve and a Quicksilver, most of the macs I have are much older than this (1990-95) so this iMac G3 is actually modern equipment to me since I haven't owned a mac past G4! :p

In addition to better graphics and MHZ, I could have ETHERNET! (dead controller)

I am bidding on one on ebay . Im a novice solder guy, I need to practice with a better soldering iron than I own currently..So the real 700 G3 logic board could be upped to 800 this way?

Possibly. I've pushed my 350Mhz G3 to 550Mhz before it started to overheat. You may be able to get 900Mhz out of a 700Mhz board.

I doubt. 700MHz is factory limit for PPC750CXe (CPU used in 600 & 700 MHz iMacs G3) - see datasheet. What ensures me in that, is fact that I've never found iMac G3 OC'ed over 700 MHz on the whole Internet. I wish that I'm wrong, though :)

Well..correct me if I'm wrong but to go from 600 to 750, it only requires mounting 2 resistors? Doesn't sound like I would botch it up..hopefully I can get a new MB!

Four, but only two may need to be changed. There are places for speeds up to 1Ghz, in 50Mhz intervals.
