PowerPC :: G4 Not Recognizing New Ram
Sep 1, 2008
I bought a powermac G4 from ebay awhile back but just recently got it up and running. So far i am liking it and decided i wanted more ram then the 384MB it was sent with. So i looked on ebay to find ram, i purchased this ram right here. [URL] I bought 3x512mb and none of the sticks are recognized in any of the 3 slots. I'm thinking the problem is that the ram is high density, can any give me their opinion on it. Also, with pc's there is a way to get to a bios screen, do macs have anything similar to that? Besides the boot selection screen? I forgot to mention, the mac i own is a powermac g4 single 533MHz cpu.

I've already RMA'd the first 1gb stick back to Crucial, and now I'm on the second. Sometimes the system boots, sometimes it hangs at a blank screen until I hold the power button down long enough to turn it off. But when I CAN actually get up and running, "About This Mac" reports that I only have the onboard 512mb. System Profiler says my singular expansion slot as empty! Yes, I've tried re-seating it-- many times. To no avail. I'm also positive the module is as far into the slot as it can go. And I find it hard to believe that Crucial would send me two faulty sticks in a row. Unfortunately, due to my built-in 512mb, I can't boot off the Crucial ram alone.

I pulled a 256mb stick out of the girlfriend's dead PC laptop and it fits in my 14" iBook G4 and when I originally put it in, "About this Mac" said I had 768mb, meaning it recognized the new RAM, now its about three weeks later and "About this Mac" says its 512mb again. So, I pulled the RAM out, put it back in, it recognized it for about a day and now its back to saying 512mb.I know when you buy RAM new, it comes with a CD(usually) to scan your computer, so is that the problem and if so, is there a download of the software online?

When I installed it, system profiler keeps saying it's 256. I have a 128 and 2 64's in there. In the 4th slot I put the 512. I tried just putting it in (to make just 512) and it still said.
What is weird is that when it only had the 512 stick in there, it seemed faster then with just the other 3 sticks. Is it just saying the wrong number?

I just replaced the original 20gb Toshiba HD in my 12" white G4 iBook (1.2gHz, 1.25gb RAM) with a new Western Digital 80gb Scorpio drive. No real issues with the swap, except the new harddrive apparently isn't being recognized. Don't see it in either the Disk Utility or System Profiler, but I can sure hear it spinning after power-up. I know it needs to be formatted, but how is that possible without being able to access it with the Disk Utility?
So, what's my next step? Anything I can try without taking the whole damn thing apart again and checking things with the old harddrive? BTW, only trouble with the old drive was its size. I've been running Leopard on it for several months.

I have two USB harddrives and neither of them are recognized by my G4. One of them consistently requires two ports for power, so I'm not surprised that one isn't working. However, my backup drive (a Verbatim) should not need that and it is supposedly compatible with USB 1.1 ports. It shows up on a Macbook. I am also quite sure that the ports themselves are working.

Well I have this problem on my iBook. At first I thought it was just my printer, but now I have it with my iPod. I plug anything in to the usb ports and it is connected by my ibook doesn't recognize anything I plugin. My iPod is sitting here on do not disconnect, but it doesn't show up on my desktop or in itunes. When I plug in my Epson printer and try to print, it wont connect to the printer, but the printer is on and the connection is good. They both work on any other computer in my house. I go into system profiler and when I click USB it just has the loading wheel going. That's all I get. The weird thing is that my mouse which is connected via the USB port does work.

I have an iBook G3 Dual USB with 256MB of RAM currently (128 on LB, and 128 in the user accessible slot under the keyboard). I bought a 512MB chip on eBay that meets the exact specs of the required RAM (512MB PC133 SDRAM SODIMM 3.3V) but when I insert it into the RAM slot and turn on the iBook, it says in About This Mac that I only have 128MB of RAM. what I can do, or is the chip possibly not compatible with Apple?

I have a iMac G5 with an Airport Extreme Card installed and an Airport Express Base Station. I have set a password on it and it is working fine on my G5.
I also have a G3 Clamshell iBook with OS 10.3 on it and an Airport card installed there. In my last home, it was able to connect to a default network without problem, but I have never been able to connect it to the same network as my G5. I enter the password and it says thet the password is not recognized. I have since moved into a new house and the only network that shows up is the one from my house (no default anymore and I can't get access to the internet.
I know the card is working since it picked up the default in my last place, but am wondering what I can do to get it to recognize the password. Should I reset the Airport Express. Do I need a more current version of OS X to run it than the OS 10.3 (I haven't updated the software as I just installed OS 10.3 from OS 10.2 last night and didn't have the connection to be able to do a software update - I could just plug it into the ethernet and do it if I need the update.
I don't want to leave it without a password. We are the only people right now in a new sub division but there will be people moving into the area soon that I don't want jacking my internet service.

I have a 366 G3 graphite iBook that was working fine in OS9 a few months ago. I took it out of the closet yesterday and installed 10.3. I did all the updates etc., and now the computer will not recognize the battery! There is a battery icon on top, but when the light is amber on the machine (charging) it says it is calculating how long it will take to charge. Once the light is green (charged) it says there is no battery. I take out the plug and the machine turns off. On top of that, the clock has to be reset everytime I unplug the machine. I don't get it, the battery was like new back in September - it would go for hours. Now it's like it's not even there!

I have a 12" PowerBook G4 that stopped recognizing the factory hard-drive some time back. I have a G4 iBook so I was not in a hurry to look into it. I removed the old hard-drive and replaced it with a Scorpio drive of 60GB. It still fails to recognize the hard-drive. If I run the Apple Care diagnostics it hangs at the start-up while 'scanning for volume' or something like that. t hangs for 15-minutes or more and never moves past. The CD-RW drive is fine as I can boot the machine into the OSX installer up to the point where it asks for a destination...at which point nothing is selectable. It is a 867MHz G4 PowerBook with 768MG RAM. This is a fantastic notebook and I would hate to see it remain in this state. Does anyone have any ideas? I replaced the IDE cable and hard-drive with all new Mac OEM parts (except the HD) and reset the PRAM or PMU or what ever it is called...with no results.

Initially it would intermittently not recognize the RAM that was in the 2nd slot (not the on-board ram). Now it does not recognize the 2nd RAM slot at all. I know it's not the stick, as we've put different sticks in to test.

I have an snow iBook G3 that I use everyday as my machine for doing schoolwork etc., so it is a very critical machine. The battery doesn't hold a charge anymore, so I just plug it in. No big deal. However, just a few hours ago the iBook started to not recognize it was plugged in. The prong has always been bent a bit, I think, and it always worked (before MagSafe type). The charger is beat up at the cord going into the power brick from the wall outlet, but it has always worked too and it seems to be a problem with the prong going into the computer. I have to hold it a very certain way for it to even detect power. So, the machine has NO way to get any power. I was thinking about taking it in to the Apple store to see if they could still get me a non-magsafe charger, but what if its something different then the charger?
The specs are as follows:
12 inch iBook
PowerPC G3
500 mhz
128 gb RAM
I have a Vista laptop I can use until its fixed, but I'd rather not use Windows. No speical prgrams or anything, I just really like Mac OSX. I have files on the iBook, too.

I used this iPod (new) previously on my husbands PC. I recently purchased a refurbished iBook G4 and it works great with the exception of not recognizing my iPod! When I plug it in, it give me the error message: Disc Insertion - The disc you inserted was not readable by this computer. What does this mean? It has been a while since I've used a mac. I've tried restarting my iPod both off and on the mac with no change. I'm worried I'll lose all my music. Have also tried repairing and verifying with no results.

My powermac G5 has been off for a week while I was moving apartments. When I plugged it in again the external harddrives (four in all) that were daisy chained through the two firewire ports aren't being recognized anymore. I thought it was a bad cord or insufficient power but nothing worked. When I finally got around to looking at the System Profiler and check Firewire it said, "Unable to list firewire devices". I admit that I'm at a loss and I have no idea how to troubleshoot this.

I'm trying to use a Blue Snowball USB microphone to record in Garage Band (run on Mac OSX Snow Leopard). However, Garageband is not recognizing the Snowball when I go to Preferences.
In addition my mac is not recognizing the snowball when I go under sound within system preferences.
The power light is illuminated on the Snowball. I tried the Blue on my friend's mac computer and it also did not recognize the mic.

I recently purchased a 15" MBP which is replacing an old PB G4. I used the PB at home and at the office and it performed brilliantly. I thought the transition to the new MBP would be seamless and it has been, save for one major issue. I cannot connect to my office server. In the past I simply brought my PB in, connected the ethernet cable in, clicked on "Network" and my office servers would appear in the Finder. When I tried the same thing with the MBP, I clicked on (my name)'s MacBook Pro>Network only to see a small icon of an Airport Extreme Base.
When I clicked on this it pointed me back to my HDD at my home which is plugged into the AEBS. That's all well and good and I love the ability to read my HDD at home from my desk at work but that's all that clicking on "Network" makes available to me. I have tried manually connecting though Finder>Connect to Server>Browse to no avail. Has Leopard made this so simple that I am overlooking a simple step or is it so complicated now that I need to bring in the IT professionals?

When I insert a blank disk into the drive, it doesn't show up on the desktop, although A CD-RW with data on the disk does show up. I've tried Sony, Imation and Verbatim CD-Rs. Running OS 10.5.6. Only other research has been to attempt searches on numerous other Mac websites, with no success.

So, to all of you using Snow Leopard, especially those with a UMBP - can you post the following : Go to Activity Monitor and post the number listed below the pie chart. Here, in Leopard the number is 2.0GB but SL shows 1.75GB, and the "wired RAM" usage increases by 256MB.

I want to import massive amounts of footage from my camcorder and I want to import them into my external hard drive. The drive is plugged in, and is recognized by Finder, but when I hit import and try selecting the hard drive to save it, the external drive isn't there.

I have a g4 dual 1.25 ghz with airport extreme card in it. I recently bought a powermac g5 dual 2.3ghz. I tried to swap the airport card into the g5, but when I did that, the computer did not want to scan and pick up any networks. Is this because I need an extra antenna? Moreover, when I put the airport card back into the g4, the computer no longer see's it. I know its firmly plugged in. What I would like to do is have the g5 use the airport card, but help on how to get the g4 to recognize it again would also be helpful.

Last week I happened to buy a new 16 gig pen drive to backup important stuff... then I started using time machine and everything was OK till today. Now whenever I pop in the flash drive to the USB port, my macbook won't recognize it and after a few seconds the drive will get really, really insanely-absurdely hot to the point that I will remove it afraid of something worse happening.

I have a 2.4 Ghz MacBook that i bought last summer, and a 250 GB Western Digital external hard drive (powered by computer) that i also bought last summer.
My problem is that My computer will not recognize the hard drive at all. it doesn't show up anywhere, and after attempting to reconnect it over and over, it will eventually pop up, and then disappear, saying that it was improperly ejected.

I'm trying (desperately!) to copy a section of a DVD. it is approximately 1h30mins long, but I only need 10mins for a work project. I am having real trouble doing this. I am new to Mac and so am probably doing something wrong. I'll run through what I've done so far:
1-Ripped the dvd to a m4v format and put it on my desktop
2-Opened iMovie and tried to import the file
3-The file is visible, but is grey and unable to be selected
4-Clicked the file on my desktop to preview it, it automatically opened in iTunes-I don't know if that is normal or not
The file is able to be played in Quicktime.

Neither Safari (v4) nor Firefox can connect to the internet. However, my internet connection is fine, and iTunes is currently downloading a video podcast no problem, in fact I can see under Activity Monitor that it's downloading at 110KB/sec, which is blazing fast for where I live (Indonesia). I can also get email no problem. And the other weird thing, is that I can use Safari for Windows no problem on my Windows side (through Parallels), which I'm using right now.
I did recently update to Safari 4, but up to now I've had no problems. And the fact that I can't use Firefox either leads me to believe it's not just a Safari problem. The only thing I can think is my ISP has recently been updating their system, and I have had some issues recently connecting, but right now my internet connection is otherwise great. Does this have something to do with DNS servers or something? Why can I use Windows browsers on my Mac no problem (through Parallels on Windows XP) but not Apple browsers? I'm on OS 10.5.7 FYI.

I have a Canon PIXMA iP4200, and I want to use it to print things. I have it plugged in to my PowerBook G4 via USB, but it does not show up. When I "Add Printer" (via Print and Fax preferences, or from any print dialog), I cannot find any option for USB printers (it is not on the Canon IJ Network, it is not a Bluetooth printer, etc. it is plugged directly into the computer)
I know for a fact that I have the driver, and that the printer works, because I have printed using this printer via a network, back before my Mac Mini (into which the printer has always been plugged) died. I have also verified that the USB cable and my USB ports are in working order. And yes, the printer is turned on.
