PowerPC :: G3 IMac DV 400MHZ With Slot Drive Overclocking
Dec 27, 2006
I just restored an old 1999 G3 iMac DV 400MHZ with slot-drive from the dead, and I feel it lacks a bit of power under it's hood. I already put RAM and HDD but the computing power is just not enough. What I want to do is go into OpenFirmware and speed up the cpu and possibly the bus, I remember doing so on my sawtooth but I can't find the code plus that was a G4 and now I have a G3. I also found this page [URL] that shows how to mechanicaly overclock up to 1GHZ but I want to be able to do it non physical if possible. I know this isn't the hot topic now a days but maybe some of you will remember what they used to do and feel some nostalgia(is that a propper word?).
I have currently acquired a few old Macs. I have got an iMac G3 SE with a slot loading drive. The computer is fine all barr the slot load drive - it has died. I have also got a PPC Mac Mini with a suggested logic board failure.
Does anybody think there is a chance i could replace the broken slot load drive in the iMac with the working one from the mac mini? i don't want to start opening the iMac up if someone already knows theres no chance it would work.
Just installed one of the original airport cards in this machine, and though all indications are that it is working correctly, it doesn't see the USR wireless router sitting 10 feet from it. No networks show up in the dropdown list, and manually adding does nothing. Encryption is a simple MAC filter (this card has already been added), and SSID is broadcast. Did I get a bad card? System profiler seems to think it's fine.
It's an original airport card. Computer's a G3 400 Mhz iMac. A G3 300 Mhz iBook with original airport card is having no troubles. Firmware of Airport card is 9.52 Firware of router is up to date. OSX 10.3.9
All help greatly appreciated; this is my moms little computer, and we're trying to rearrange and loose some wires.
Recently purchased a new desktop so i wouldn't mind tinkering with my OLD iMac G4 1.25G Is this processor just a over clocked 1g G4? I would like to add more ram and over clock it to 1.5g or higher if possible. Is there anyone who would know how todo this? I assume i would need to change jumper setting within the computer right? What would the setting be?
I mainly use this for music and simple everyday tasks and its soooooo slow compared to my MBP and MP.
I have a g4 slot loading drive and I am fulling aware the outside casing would be wrong... but that isn't much of an issue, I can replace the panel/casing section with a new panel to take care of that... i just want to know if it is possible as far as hookups etc are concerned.
First and foremost I should tell you that I am a new convert from Windows.
I'm currently running OS X 10.3 and find that I can not read any of my DVD+R discs but I can read my CDRs just fine. My guess is that the optical drive is simply too old to recognize the DVD+R format. Is this correct?
My alternative to this would be to purchase a firewire external drive enclosure and put one of my newer dvd burners in it, but would I be able to boot from this type of connection or do I have to actually buy a "superdrive"?
Until yesterday, my iMac G3 slot is working fine, but today, I can't power it up. When I press the power button, the light just flash and then went off. I've opened it up to check the PRAM batt and also checked if there are any shorts on the logic board. All looked ok to me. The HDD is working fine and I supposed the power supply unit is fine too.
I have a G4 powermac 400 mhz with os panther 10.3.9 installed Can this G4 be upgraded to Tiger and if so which version.There seems to be many versions of tiger ie some say amd or intel etc If i can upgrade which version should i look for
I have a charcoal iMac DV SE 500 which won't complete a proper start. The machine chimes and begins to start, and then clicks off again before anything can show on the screen. It won't start in Target Disk mode, and zapping the PRAM (starting with alt/apple/P/R, right?) has no effect. Does this sound like a dead PRAM battery, a dead 'Power/Analog' board, or a dead hard drive? Can anyone give me an idea of how much it would cost to fix, and recommend good, reliable, cheap UK repairers It's not worth much, but I have a friend who'd love it if it can be restored to life, and I'd like to get some of the files off it if it's not the drive.
I bought a second hand iMac G3 off eBay for a pretty good deal, and am trying to figure out where the buzzing is coming from.
It doesn't come with any CDs so I don't think I can do a hard wear test, but I've noticed it is happening even when the display is off, and is in sleep (although it gets less audible in sleep).
Another thing I noticed is that in OS X it will stop after a while of not using it, despite the screen being on and still showing the image, is this the hard drive stopping? When I go and touch a key or move the mouse it starts again.
I bought 4 G4 towers of eBay for �85.. none have Hdd's so havent tried them out yet (two also have no graphic cards) I got a mix of ram size and speed (pc100/pc133) however thats not my question
Next to the ram slots theres a red light that comes on, is this normal? I've tried to do some research on it and some people say it is, others say it isnt.
I plan to sell them off again on ebay but I did it mainly as a project to keep the G4's alive. Any suggestions on graphic cards (cheap ones too)?
I running a 400MHz sawtooth Family #M5183 my friend gave me with a 40 gig hard drive running OSX 10.3.9. I just picked up at the swap meet a Qwicksilver Model No.M849 PNG4 1GHZ DP/2M CACHE/512MB SDRAM? 80GB HD DVD-R/CDRW/Nv17 DUAL/56k MDM/GIGE it is missing the HD from under the superdrive can I just plug in the HD from my Sawtooth and run her? She still has the HD in the bottom its a 80 gig IBM Deskstar. When I opened my Sawtooth I found that there is a Seagate Cheetah model#*ST118202LW* Its not even plugged in!!! How many gigs is it and can i run it for more space? I have three 512 cards for memory. Can I use the video card from the sawtooth to run a second monitor? If this all works whats the newest operating system I can run? As soon as I get the money I am going to swap the processor and bring her up to speed. I am a singer/songwriter on a budget trying to put my studio together,I run live sound and make Hand Drums.I'm not a computer tech by no means but I do ok running a mouse to get a good sound. If you are going to tell me to wrap machine in tin foil and put it in the freezer PLEASE don't waste my time!!!!! I just want to build my machine correctly and not f@#$ anything up.
I want to do this to increase the speed of my sawtooth. I think that the dual 500mhz was the last apple processor that is compatible with the sawtooth because they both run on 100mhz busses, correct?
I have a G4 PowerMac 400Mhz running OS 10.4.8. The graphics seem a bit slow at times and I was wondering if upgrading the video card from the current ATI 16MB to a GeForce2 32MB would help? I have 1GB of memory so I know I am good there.
This is not related to the other bluray thread on here. I am looking for a slot loading Blu Ray drive (I do not want write capability) for my iMac Aluminum. I know fastmac sell a Bluray drive for $999, but that has the unnecessary write capability which jacks up the price. So, does anyone know where to get a slot loading BD-ROM for the iMac?
Today I was planning to build in a second harddrive into my old G4 tower. So I did this. But after installing the system won't boot anymore from the OS X Tiger partition. I have tried all sorts of jumper settings, from slave to master to cable select. All without success.
When I boot from the Tiger installation CD diskutility does not even recognize my original master drive nor does it recognize the new slave drive. I even tried to boot from an old OS9 disk to initialize the disk. I tried formatting it in another machine to HFS Journaled, no success in booting mounting the disk whatsoever.
I recently added some extra RAM's but i doubt these are the problem since my machine DOES boot without having the new disk installed in the system.
It is a 60GB Maxtor drive, so it is within the maximum amount of GB's possible for these older machines.
I found one on craigslist for $15 but want to make sure it will work, or if I do get it and try to install it I want to make sure I don't break my computer.
Instead of placing my sdhc card into the memory card slot on the imac I placed it by mistake in the dvd drive and it just swallowed it up and I have no idea how to get to it.
I have accidentally slot in my SD card into the disc drive. Is there anyway I can take it out again? Will apple charge me for this? It is still in the warranty period. Anyway, I have to pay if they charge me. So careless!!
I recently bought a PowerMac G4 1.42GHz Dual Processor. It has 2 gigs of RAM on it. It was a fair deal I think. The "thing" is still looking like new and shiny. Even the insides are still tidy and intact. My question is, would I still be able to pump more juice from this beast. It still run fast comparable to some decent windoze box. Up to how much processor can i be able to squeeze out the CPU and if possible, how to?
i have 1.25ghz mdd default jumper settings is like first table now i have jumpers like third table. about this machine shows 1.58ghz now and its unstable so how i get this f..king 1417mhz
I have a 1.33ghz 1.28gb ram 14" ibook. I have leopard on it and have optimized it as much as possible. Ive got youtube videos running pretty smoothly but there in an online TV service I use that drops a frame every couple of seconds. I was wondering if i overclocked the graphics card by 10% will in slightly improve the playback of flash?
It originally had 64MB RAM, and a it now has 2 sticks of 256, but it is only seeing a total of 320MB, so I don't know what to do. If I need to give any more info on it, let me know.
My former, babied, 400mhz overclocked by Daystar to 550mhz Titanium Powerbook has a fried logic board. Can I put a the old low resolution Tibook screen on a 1ghz Tibook body with a higher resolution screen?
Would it just power on at the lower resolution or is this just idiotic?
I just got a G5 power mac (dual 2.3GHz) and bought one of these: [URL] as an airport substitute. When trying to install the card it doesn't appear to fit in the PCI slot. Am I right in thinking it should fit? Since it's a PCI card and the G5 has PCI/PCI-X inputs?
