Power Mac :: G5 Won't Recognize New RAM / Why Is So?
Oct 9, 2007
I bought two sticks of this RAM http://eshop.macsales.com/item/Other...g/3200DDR1024/ and put it in my Dual G5, following these instructions http://www.info.apple.com/usen/cip/pdf/g5/memory_c.pdf , but when I go to 'ABout this Mac,' it doesn't recognize that I've added RAM. I put the two sticks in slots 3 and 4 of the bottom half. I then tried putting the RAM into slots 3 on top and 3 on bottom, and then 4 on top and 4 on bottom....but it still won't recognize it. Did I do something wrong?

My Power Mac Dual G5 will not recognize my GeForce 6600 LR2A22 Video Card. I have it plugged into the VGA plug. The computer sounds like it starts up fine (chimes, DVD drive runs, hard drive runs), but does not show video. I have tried a new Battery?I have tried the PRAM tricke (did have two chimes)I have tried unplugging hard drive?Is this a video card issue (says its a brand new working card from ebay)Tried on multiple VGA monitors.Â

I have a PowerPC G4 running OSX 10.4.11 that contains a lot of media files. I want to transfer them to my external hard drive (1 tb) so that I can use them on my newer MacBook. I was unable to partition or erase anything on the external hard drive from the PowerPC, because I kept getting an input/output error. I followed the same process and was successful at establishing partitions on my MacBook. Now, I plugged my external into the PowerPC to copy the media files, but it isn't recognizing the partitions on the external harddrive! What did I do wrong?

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.

I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.

I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.
A clean install of Leopard eliminates the infamous power supply beeping
Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.

a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

I hav" a "late 2004" G5 2.0 dual processor. To upgrade graphics card, I find many require a power supply splitter. Do I have a molex 4-pin connector? I can't see the location inside the box.

I have the problem that I need to frequently power cycle (shut off and on) my dsl modem to maintain a reasonable speed with my internet connection. It is making the internet experience pretty user unfriendly. Does any one know whether there is a way to optimize my internet connection such that this is not required so frequently (couple times a day)? I am on my second dsl modem, and the same problem has occurred with each of them. ATT simply advises me that my solution is to power cycle the modem to sync the system, whatever that means.

I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.

I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.

Anyone know where I can buy an extra AC cable for the MagSafe 85W power supply that came with my late 08 MBP? I'd like an extra cable and I'm not interested in ponying up the dough for the entire power supply. I checked the Apple Store and Macmall, but haven't found anything as of yet.

I've been suffering of slow speed on my macbook pro, and this happens when I unplug it from power and just let the battery works itself, then the % CPU usage increases dramatically to 330%Â and the laptop becomes very very slow, what should I do? Because if my macbook is off-power, it doesn't work properly, so what is the point to own a portable computer?

I have a problem described by Apple in document Power Mac G5 (Late 2004) 1.8GHz models stop responding randomly.
How can I update the firmware because my G5 1.8 screen is blank? Thought that I could make my G5 1.8 as a hard disk for my MacBook, or I may try to update over the network. Is there a risk of corrupting my MacBook if I try?

Power supply partially expired on my 2.3GHz G5. Have found a donor. Manual says remove logic board before power supply. But you could remove power supply with board in situ on older G5s...

I still have the same G4 Digital Audio which came used but with a clean OS, which I managed to up grade to reach the 10.4.11. Its works great and I love it. I can only imagine using a real Mac Pro 2012. The software is legacy and It will not support the QuarkExpress9 for example. So what if I found and upgraded to the 10.5.8 or the max OS my G4 can handle? Is it worth it?Â

I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?

a MacBook Pro, Retina, mid 2012 running Yosemite 10.10.1...I've noticed that since upgrading to Yosemite, if I close the lid on my computer to put it to sleep and then leave it overnight, it is completely drained by morning. It used to burn through, MAYBE 5% overnight. All the power settings are set for no power usage, i.e., no power nap, no wake for network, etc. If I look in the system log, I see something that happens every hour while it's asleep. I've included an excerpt below.Â

Today I turned on my G5 to recover some files off an old iMac hard drive (can't very well read HFS+ using Windows), and my G5 refused to boot. Your press the power button, the power light flashes normally when you press on the button, but it powers on but the power light never comes on and there isn't a "bong" sound. The fans come on normally, but after a while the fans start picking up speed until they are at full speed.
I tried swapping ram, no change. Pulling ram, no flashing lights, pulling air deflector shield, full speed fans and red light (tells me something is working at least), swapping the video card, pulling the video card and still nothing. The 17" Studio Display power button works to turn on the system, but it has no light either saying the computer is on.
Based on the full speed fans after a while, I'm willing to say I have a failed processor, but that is just a wild guess as I don't normally work with Macs. The system is a Dual 2 GHz Power Mac G5 with 2 gigs ram, 80 GB hard drive, Plextor PX-712A DVD burner (I got this with a DVD-ROM), stock Radeon 9600 Pro and an Airport Extreme card. It runs Mac OS 10.5.8 and has worked great up until today.
