eMac 800Mhz -> 1.33GHz conversion

I don't think mini-pci has all of the same lines as standard pci...I'm trying to remember off-hand what the differences are. Some will work, but only the ones that don't utilize the extra traces.

The other problem becomes of course driver support for whatever pci device you're wanting to plug in.

old g3 imacs

I've been looking at the g3 350mhz imac and find out something on the board that could be the pll clock signal chip.

It as the reference IMI C5002BYB 0032 T3010

Anyone know what can be done with this?

old g3 imacs(2)

i found ibm info for the processor at http://www-3.ibm.com/chips/techlib/...PowerPC_750_Microprocessor_(300MHz_to_550MHz)

old imac g3(3)

And the multiplier settings at http://www.bekkoame.ne.jp/~t-imai/imacde1.html

old imac g3(4)

This mac uses the motorola XPC755A processor http://e-www.motorola.com/files/32bit/doc/data_sheet/MPC750EC.pdf

imac g3

I found some info on this japanese page about imac DV http://www.bekkoame.ne.jp/~t-imai/imacdj3.html

that was a great article

i want an emac over my imac 15" now...

can i over-clock my imac 15" 700 g4???

Lbodnar, I think you should create one massive eMac modding site

(I really want an eMac...)

Do you mean other than this site?

Keep that.....and just include all the little bits like the fan mod.

Add stuff like how to replace the HDD, etc, and maybe a tweaking guide.

IMIC5002BYB Settings

I think these are the FSEL for this chip but i'm not shure about the FSEL order...

IMIC5003BY settings

Here's the pdf http://homepage.mac.com/dgiessel/.Public/c5003.pdf

The settings for bus speed...

With much thanks to BigBadMac, my eMac works again!

What was the problem? Seems your eMac was dead for like a month!

Will this hack work for a 700mhz eMac?

Kinda new to macs and not very familiar with the "technical" end of things. I'm not going to get a new mac until fall and would like to put a little more life into my eMAc. Any suggestions would be appreciated in helping me facilitate this hack.

eMac 700 overclock

I've put up a site for all of us 700 eMac users... http://www.studio-northwest.com/Hakz/index.html

more speed

Thanks Ibodnar. I have 1ghz emac now running at 1.27 ghz with no problems!! I also installed a new 120 gig western digital hard drive and installed a pioneer dvd burner. My xbench score is 119 up from 100!!! Any one know how to get more performance from the video card or even make increase the bus from 133 to 167????? Thanks again.

any one know if its possible to change the graphics card in the emac the radeon 7500 is a little slow would it be possible to pop a new video card in the agp slot

AGP Slot???

Actually, there are no AGP or PCI "slots". The graphics chip is soldered directly to the MB. Sorry...you got what you got...be happy!

Hey guys, I'm back!

Did you miss me? I know you did.

I didn't get a chance to clock up the bus speed on the imac 800 yet. I got evicted, then started to buy the house, then got evicted again, bought another house (3 weeks till closing), moved out of state, and after closing I'm moving back!

I just got my hands on a 233 Bondi, and I'm going to be overclocking it as well . It's going to my sister and her kids, so the soldering iron is back on the prowl again, and after seeing the CPU daughter card for the Bondi, I think I finally understand what I need to do to finishing clocking up to 1.33Ghz on the 800, but I get the sinking suspicion that a peltier cooler and possibly an external power supply will be required. I think I'd just be thrilled with ~900mHz@133mHz frontside bus.

Anyway, I'm back on the case. Also considering upgrading to a G4 433 in the bondi, and then trying to overclock from there. Who knows?

hmm..

sounds alittle risky to me..i couldnt afford to screw up...

i was wondering can you overclock the 1.25 ghz emac and what to

7500's are decent live with it


there is an agp bus on an emac but the card is part of the logic board so unless you feel like finding the circet traces soldering on an agp slot and modding the emac so one fits and dose not overheat live with it
