PowerPC :: IMac G4 1.0ghz 17" More Than 1gb Of Memory?
Jan 30, 2007
I am looking to upgrade the current memory in my iMac. It has 512 (2x256) and it says it supports up to 1gb total. However, i have been searching all over this forum seeing if it is possible to have more. Like if I added a 1gb sodimm to get it to 1.2gb. I have seen very little on this as I have searched these threads. Also, is the upgrade in memory really going to help me out? I really notice the slowdown in iMovie. I have been watching the activity monitor and even though the cpu can get up to 100%, the free memory will be down to 4 mb. oh ya, I am running 10.3.9. When i update the os, with a clean install, will i see any improvements without additional memory? Or will i need more memory just to keep tiger or possibly leopard running good?

ive got a Imac 17inch 1.0ghz with 215mb ddr ram. anyways, as Sheepy suggested, i upgraded her to a nice speedy 500GB 7200 Sata drive and dropped 1.5gb ram into her...... but lets take a step back. when i got her, she was full of dust and had tiger on her.. no dramas, tiger is good. anyways, i wanted to do a reinstall of tiger, and so grabbed my tiger retail disk and started her up, no dramas there either, ran disk util, repartitioned (the old disk) and started to install. the install never finished and then it just rebooted after about 80% through... The reboot came to the disk flashing with the osx face and a question mark. I try a few more times, with the same result, and also with Leopard, also with the same result, but the leopard install actually tells me after about 80% that "Install failed" try again? anyways, so i think its a shagged optical drive. i have a few lying around and i need to get in there anyways to upgrade the hard drive. installing the HD and the new Optical drive went fine, all works well.. and while i was there also installed 500mb ddr400 stick in the main memory non user slot. close her up, checked the heatsink matchup spots and there dry as a nuns nasty.. theres no paste on them, but kinda like a pad.. (which isnt even sticky either) anyways, i stick em back together (without) cleaning the pad stuff nor with applying any paste and boot her up. I insert the leopard disk to istall and it all goes fine, i re-partition the newspeedy 7200rpm sata disk and start the install. and again.... gets to about 90% and reboots. flashing smily face with alternating question mark.

I just bought a new Mac Mini. I bought 4GB of RAM for it, and I understand there is a 1GB memory stick that I'll take out to put in the 4GB (2 x 2GB).
My question is: will that single 1GB memory stick fit into my friends iMac, which is a 20" white iMac 2.0ghz intel?

I listed my Dual 2GHz G5 on ebay and hope to sell it. In the event I can't, would it make a good server if I throw Mac OS X Server on it? Would a server be of any benefit since my network consists of my Mac Pro, Mac Book,a nd Xbox 360?

I was wondering if Leopard would slow down my old iBook. It's a 1ghz G4 with 1.12gb RAM. Would Leopard be okay, or should I just keep Tiger on it?

Our old powermac died recently (G5 2.5ghz x2), the cost to repair was quoted at 850$, which is roughly the same price as a new Mac-Mini 2.0ghz. Just wondering how the performance of new mini compares to the 4 year old powermac? A new powermac is out of the question right now.

Hi there, a couple of easy questions I hope.
What is the simplest was to increase the memory on a 10GB Imac G3. 9.7GB are used up and there isn't much I can delete to free up space. It is a friend's computer, she is not mac savvy.
Also, I am considering rebooting the system as there is an account on there with a forgotten password and the original administrator password is long forgotten. What would be the best way to go about doing this? I have 10.4 os discs, with extra memory would this work ok?
Thanks in advance.

My internet is very slow! It's not the service as I have 2 other computers who run very fast on wireless. I just replaced the ethernet cable which didn't do anything. My computer itself isn't that slow although it isn't fast either. It's a imac, 10.5.7, 1.8 GHz PowerPC G5, memory 2GB DDR SDRAM.
I thought about switching it to wireless,I'm not sure as I don't see it on the top toolbar and I'm not sure how to set it up if my machine actually has it. Could my router be bad if my other computers are good?

tell me the main difference between 2.0GHz and 2.26GHz. I'm buying the base model and upgrading to 4GB, just wondering if I should fork out the $180 to upgrade to 2.26GHz and will I see a huge difference?

I am about to buy a computer and just been doing some research. When I went to best buy and ran a geekbench score on the imac it was like around 5800.
A seller on ebay who is selling a Mac Pro 3.0 ghz just ran the score and posted the results of 6214
[URL]
Based off of this score alone wouldn't it mean that the 2007 Mac Pro is faster than the newer 2010 imac

I like eMacs but the G5 looks sooo nice. I know I probably won't be able to use any for very long but whatever. What is the best?

does anyone know how much memory would the PowerBook G4 (the very last one, 1.67GHz with DL SD and 15" HD) take?
apple- says 2GB, but is that limited by the motherboard or by the fact that when this machine went out of production, 2GB sticks weren't available yet?

I have inherited two PowerMac G4 450 MHz AGP machines for use at the non-profit arts organization that I help run. I believe these are either the "Sawtooth" configuration [URL] or the "Mystic" configuration [URL], probably the former.
They each came with two 128 MB DIMMs (256 MB RAM each), which is anemic of course, so I bought two DIMMs of 512 MB RAM of the same type, intending to add one to each machine. Same bus speed (133 MHz) and voltage configuration (contact edge indents) as the existing memory. There are 4 DIMM slots.
The DIMMs go into the slot just fine, but are not recognized by the system. It boots up as if they aren't there; there are no abnormal boot beeps or flashing power button. It just doesn't count them as existing in the RAM pool (per "About This Mac").
I did try both DIMMs all by themselves, separately in the first slot and together in the first two, and those boots failed with the warning beep, flashing power button, and no video.
I can take these back to the vendor (a trusted local whitebox shop) and have them test them, but is there something special that I need besides PC133 SDRAM?
I noticed that these new 512MBs are 16-chip DIMMs, and the existing 128MBs are 8-chip DIMMs. Does that matter? I vaguely recall that there's a difference between 16-chip and 8-chip.

I don't know what the deal is. I'm trying to install 2 sticks of 2GB into my 7,1 iMac, and the screw just won't turn. I'm using a standard Phillips head, and nothin' doin'. The screw is now starting to strip, so I guess I'm going to have to take this into the friggin' Apple Store just to have them open the thing.

Is it possible for me to put a 1g memory stick in my PowerBook 12inch 867mhz? The reason why I'm asking this, is because when you check the apple store, the maximum memory is 512mb. But if you check elsewhere, you can buy the 1g stick. Some places says that the computer will recognize only 512mb, even if you put the 1g.

Sometimes hear things of Macs supporting more memory than listed, so I was curious about my Powerbook. 12-inch Powerbook G4 1.5 GHZ. I have the specified limit of 1.25 GB. Has anyone here ever tried a 2 GB stick in it? Doesn't work?

So my dad decided to upgrade the ram on his Powerbook G4 to 2GB. Initially everything went smoothly and the ram was detected and working. Within a week though, the computer only recognized 1 of the memory slots. Switching the ram cards around proved that the ram itself was fine but that the one memory bank was not working. Is this at all a common problem with the Powerbook G4? Our concern is that a repair may cost more than it is worth considering this is an old machine.

I was wondering what is the max memory that I can put on my iBook G4. My G4 (12 inch) has 128 MB DDR SDRAM soldered in place and has a 800 MHz PowerPC G4 Processor. I was wondering what is the most memory I could install and what is recommended? Also I am only running Mac OS X Version 10.4.11. Is it possible for me to update to 10.5 or higher? Sometimes when running videos on google video or youtube it gets choppy and lags what fixes this problem. A message pops up about quicktime not up to date but I try and do a software update and it says that my software is up to date could this be because of the older software?
Hardware Overview:
Machine Name:iBook G4
Machine Model:PowerBook6,3
CPU Type:PowerPC G4 (3.3)
Number Of CPUs:1
CPU Speed:800 MHz
L2 Cache (per CPU):256 KB
Memory:256 MB

The other day, I put more ram into 2 12-inch ibooks - my own 1.0 ghz, and my wife's 1.33 ghz (Yes, I know she has the faster machine. It means I'm the next to upgrade). Anyway, this is the first time I had opened them up at all and I saw something that confused me: I know that ibooks have only one available expansion slot for ram. That's what I saw on mine. But on my wife's, it looked like there was a second slot lower down, just below where I installed the ram, but missing the clips to hold the ram in place.
Is this in fact a second ram expansion slot, or is it just the shape of it that makes it appear to be one, or is it a second slot that is somehow unsupported or unable to be used? My guess is that it's just the shape of the hardware, and it only appears to be a second ram slot, but isn't really. But wouldn't it be sweet if there was in fact another usable slot in the ibook?

I own a 900 MHz G3 ibook (v2.3) with 256 MB of ram running 10.2.8. It's been good to me, but over the years it's performance has started to decrease. Most applications load up and run fine, but web browsers can become a little slow when I have multiple windows or tabs open. What should I do to get rid of this problem? Upgrade the memory to 640MB of ram? Update the OS to 10.4?

Can you add memory to an iBook G4. And can the new AirPort extreme card be installed in the same computer. It has an AirPort Extreme but I don't think its the newest one.

So I've got a 2.0 GHz, white MacBook with 1gb ram, and a G4 Powerbook 1.67 with 1gb of ram. The major software difference between the two is the OS, the MacBook is running Leopard. So, I noticed the MacBook started to lag a little from when it was new, so when I upgraded to Leopard I did a clean install. Still noticed the lag so I checked my ram, and here's what I got:
The Powerbook was running the same exact apps (iTunes, iChat, iPhoto, Safari) as the MacBook, and even after loading dashboard on the Powerbook it still used only 500mb of ram and 4.45gb of Virtual Ram. The MacBook was using 615mb of ram and 32 GB OF VIRTUAL MEMORY?I thought it might just be counting space set aside, but I checked the apps and adding all them up is about 32gb. They both have the same iPhoto library yet the powerbook's only took up 240mb of virtual ram and the macbook's over 1000mb.
I realize there are some slight differences (different iChat, spaces was running) but why in gods name would it make the MacBook use almost 7 times the amount of virtual ram!
