Dead Powermac G5 Quad?

Hi I have a Powermac G5 Quad, late 2005. It has just begun to not turn on at all. After trying to start the computer it will begin to start, fans whirl, drive move, however no start up noise, then about a second or two later, red lights come on on the motherboard. I tried doing a SML reset to no avail. I've been looking online and no one else seems to be having these issues. Not sure if there is something I can do easily, or if someone has a similar expirience. Was looking and people have said apple has replaced these for them even out of warranty in the past, but I'm not the original owner so not sure if they would honor me at all. Hope someone has some ideas.
The specs on it:
Quad 2.5Ghz G5
4.5 Gb of RAM
Oh and thought it might be a coolant leak but I'm not seeing any spilled in there...
Please help!!!

Hi Japamac, No it does not respond to anything.
So here's what I ended up doing, I started reading about liquid damaged macs and that apple was fixing them for people. So I ended up just taking it to the apple store for them to look into it. I myself had felt like I saw some liquid seepage by one of the cooling tubes. However they called back the next day and told me they found nothing, I told them where I felt the leak was and they said they would look into it further. Now I just called back after a week of not hearing from them, was told oh sorry you were supposed to be called, although I never received a call of any kind and I never turn my phone off so I would have seen it. They told me that they found no liquid damage and that it was probably a dead processor as they die after a couple years. Right now I'm a little ****** off, I mean come on a $3000+ computer and they are telling me that they processors die out after a couple years. Yeah and its not like its too cheap to fix either! Anyone have any suggestions? A little ****** right now, maybe I should sell all my Macs and go buy a PC.

PowerMac G5 (quad) vs Intel Macs?

Hello what would be better? The PowerMac G5 (quad powerpc 2.5ghz) or Intel Mac mini or Intel iMac.
i don't have enough money for a Mac pro, so that's out of the question, but on ebay, the Powermac G5's (with quad processors) are about the same pice as mac mini's and a little cheaper than the iMac's. But would I be better off with an intel Mac or the G5 quad. I'm leaning towards the G5 because I can upgrade two hard drive slots and the RAM to 16gb.
Which is better for gaming, day to day stuff and animation software?

Thanks for the suggestions guys...I know I'm a few months late on the post and for that I apologize. Anyway I purchased a Quad-Core PowerMac G5 on Ebay last week for $600. Here are the specs:
-2.5ghz Powerpc G5 quad-core
-9gb RAM
-1.5 tb HD (1 x 1tb & 1 x 500gb)
-Built-in wifi & bluetooth
-Geforce 6600 w/256 VRAM
I also purchased 12gb RAM on ebay for $124...they're all Kingston so that will be nice. I'm going to max out the RAM and I'm also thinking of Installing a small SSD for my boot/applications drive to speed it up a bit. Anyway I'll keep you posted. Thanks!

Will the new ATI graphics card work on PowerMac G5 Quad?

Hello,
I'm having a problem with my PowerMac G5 Quad, simply the graphics card is at fault. The rest of the machine is in perfect working order. I need a new graphics card and i've searched ebay (UK) and found some products. However, I would like a new graphics card with a little more power.
As I develop code using the OpenCL API on the windows machine, I would like to transfer this process over to my Mac (have to install OpenCL API myself, as Leopard does not have native OpenCL support). More importantly, OpenCL supports selected GPU types i.e. latest GPUs from ATI/Nvidia.
Simply put, would anyone know or have experience installing the newer ATI/NVIDIA generation of Mac Graphic cards on PowerMac G5 Quads and if so, which graphic card (ATI RADEON 4850 etc).
As I think about this, both PowerMac G5 Quad and Mac Pro utilise PCI-E and yes, even though graphics cards are not particularly interchangeable on different architectures (or are they?) I would just like to know if anyone can give me advice or if anyone has had success or failure at such an attempt.
I really cannot afford to buy a Mac Pro machine and there is still many years of life left in my PowerMac G5. I really need your help and advice friends.

Hi-
Welcome to Discussions!
No modern card will work in a G5.
The best that one can do in a PCIe graphics G5 is to use a flashed Geforce 7800 GTX 512MB card.
That card is the pinnacle of GPU power for a G5.
There are no options beyond that.
Here is a full, "short" list of options:

PowerMac G5 Quad doesn't start up (crashes and fans become real loud)

Hi all,
I started having problems with my PowerMac G5 Quad 2.5GHz (late 2005) about a week ago. First I found the computer with the fans running at full speed (really loud) after leaving the computer alone for a while (instead of going into Sleep mode). At this point, I wasn't able to recover it from that state and had to force it to shut down by holding down the power button. Another thing that caught my attention was that a couple of red LEDs were on (just behind the power button).
Last night, after finding the same situation and shutting down the computer, it would no longer start up. I could hear the hard disk starting to spin and the chimes sound, but I'd get no video at all (no gray screen or anything). After trying 3-4 times, the computer finally started up.
The situation got worse this morning, as again I found it with the fans on full blast. Now I can't get the computer to boot anymore. I no longer here the chimes sound or get a video signal at all. I can't open the CD tray either (it doesn't seem to recognize the keyboard) so I could not boot from a CD. And holding down the power button is no longer shutting it down, now I have to unplug it.
I've already tried relocating the RAM, resetting the SMU, and read about resetting the NVRAM (however, this was not possible as I have no response from keyboard input).
I've not installed any new software or hardware lately so maybe this was caused by the latest software update. After reading forums and searching the web, it looks like this problem has become quite common in the past few weeks. Has Apple taken any steps to solve this problem on the affected computers?
Any ideas or suggestions would be of great help. Thanks!

Man it sounds like what happened to my G5 quad before it died. Sounds like your power supply is done. There is a link on the lower right side on the SUPPORT page under EXCHANGE AND REPAIR PROGRAMS... There is a recall on the power supply of these models but Apple is not honoring it. Here is my story:
In April of 2009 My Quad dies and won't start. I bought this machine in January of 2006. I bring it into the Apple store and they said it is the Power Supply, but will cost over $500. I decide to buy a MacBook Pro due to the intel chip needed for newer programs.
August 2009- I find that Apple has announced a program to fix the Power Supply on the G5 Quad. (I guess they did not know about this repair program in April at the Apple store in Kahala, Hawaii). I figure that even though my computer is just over 3 years old they will surely fix it for free. Nope. Denied. "You gotta pay son".
Imagine if a car company announces a recall on a part that will render your machine inoperable and then denies to fix it.
I am very upset. If this does not get fixed for free I will not stop bad mouthing Apple until the day I die.

PowerMac G5 Quad GeForce 7800 GTX 512mb or Quadro 4500 FX

Hey, best regards for all users. I have a question about changing graphics card. I'll be gratefull for all help.
I have PowerMac G5 Quad Late 2005 - M9592LL/A and OS X Leopard 10.5.8.
My card is GeForce 7800GTX 512MB and Quadro fx4500 model p348.
I'm looking for ROM for this cards for Mac G5. I want to change 6600 for 7800GTX 512MB or Quadro. Cards tested on PC are working.
Anyone can help ? I can't find any info about ROM for this cards.
Thanks all !

Both the X1900 (R580) and the 7800 GTX (G70) are capable GPUs on advanced cards, both targeting and supporting Shader Model 3.0. 3D was a focal point in development for either card.
Approaches for shader implementation are very different between the two cards.
Arguements for either abound, but, 3D performance will be a defining factor to show shader prowess.
Architecturally, the cards are very different, but, in the end, memory bandwidth, an important performance feature, is highest with the 7800 GTX; 54.4 GB/s vs. 38 GB/s for the Mac Edition Radeon.
The next X19xx card, the X1950, almost doubled memory bandwidth over the X1900.
I know guys that use flashed X1950 (512 MB) cards really like them.
Support of DirectX 9 and Shader Model 3.0 make either card more than is necessary for OS X Core Image and OpenGL requirements.
You bring up a very important point regarding application specific performance.
Games are one form of benchmark, but not always indicative of real world performance.
In Photoshop, CS4, the 7800 GTX is a fully supported card, whereas the X1900 (256 MB) card is not supported. The 512 MB version of the X1900 is supported, but doesn't help owners of the Mac Edition.
There are pros and cons with either card, eventually driver and OpenGL support being the defining point.
Early driver issues with the X1900 in OS X and a relatively short retail availability likely affect the lack of empirical data on the cards performance.
The following, though comparing a X1900XT (not the little brother X1900GT which is the G5 version) with a Geforce 7800 GTX on platforms other than Mac, the comparisons do show pro oriented application performance.
Though not necessarily applicable to OS X and PPC Macs, I thought it to be an interesting set of tests.
http://ixbtlabs.com/articles2/cpu/nvidia-vs-ati-on-amd-and-intel.html
Either card is great, either is way better than the 6600, and, as you point out, availability is an important factor.

PowerMac G5 Quad 2.5 Video Card Upgrade?

I've been trying to upgrade my video card (for Final Cut Pro) in my PowerMac G5 Quad 2.5, and I'm trying to figure out which card(s) would be best for me. (can't get a Mac Pro 'till next year)
I guess I'm right on the cusp of the PCI Express connection. (is that true?)
Can someone point me in the right direction. Latest I was trying for were the Radeon x1900, or one of the 2800/2600 pro mac edition. Not sure, now, which connection is correct, though...
Thank you for your help!
joe

Thanks. I'm still trying to make sure my computer is indeed the PCI Express slot.
I can get a Radeon x1900 card (used) that was in a MacPro - but I don't know if that's the same slot either. I thought I read that people HAD put the x1900 cards in the G5 Quad. Would the Mac Pro NOT have a PCI Express slot, therefore this card would not work in my G5 Quad? How can I tell. I got a description from the person selling it - but I can't understand it.
(I also meant to say the other cards I was looking at were the Radeon 9800 Mac and the 9600 Mac - late typing, sorry)
I currently have the 6600 stock video card that came with the computer. Since Final Cut Pro 6 really needs speed (on my MacBook Pro it's struggling a bit), I thought it would be the one thing I could do, since I have 6.5 gigs of ram and plenty of drives and space. I'm tempted to wait, but the need for speed is tough...
Thanks for all the help.

Any experience with DDR2 RAM from Legacy Electronics (PowerMac G5 Quad) ? ?

hi, I´m looking into upgrading my PowerMac G5 Quad with 8GB RAM DDR2(4x2GB), and came across a kit from Legacy Electronics for $740 (w/lifetime warranty). I already have 8GB from OWC installed, but they want $1100 for another 8GB..
Anyone had any experience with RAM from Legacy Electronics ? The price on this kit seems almost to good to be true.. is this crap ?
Here´s the specs :
8Gb (4x2048Mb) Memory Kit
DDR2-533
PC2-4200
Dual-Channel
Matched Pair
Lifetime Warranty
30 days Money Back Satisfaction Guarantee
Guaranteed Compatible with Apple PowerMac G5 (DDR2 / Dual-Core models only!)
Any input is highly appreciated.
THANKS!

B?rre S?thre-
That is an amazing price. I have no experience with Legacy Electronics. If it has a lifetime warranty that should help, but if it is the kind of company that won't be around in 6 months it really doesn't matter.
As I am sure that you know, most issues with RAM (once it is known good and working) come from subsequent OSX updates. The warranty should help with that should it not work in the future.
Lemme know if it works.

I'm guessing that my Powermac G5 Quad running 10.4.11 does support extended desktop. My present monitor is a 1600x1200. Can a second monitor of smaller size and lower resolution work as an extended desktop?

Software or Games for a Powermac G5 Quad?

I recently got a Powermac G5 quad that was in storage for a long time so its basically brand new still and i was luckily enough to get it for free.. It has 16Gb ram and 6600 Nvidia graphics. I know that its very dated and no software can really run on these things now. I just really wanna push this thing to the limit and test its power out with any software or games that can still run on these things. As i should i am running 10.5.8 thanks for any suggestions.

Graphic card for a PowerMac G5 quad 2.5ghz

I have a powermac g5 quad 2.5ghz with a 30in cinema display and i am looking to upgrade my graphic card so that i get better resolution out of my monitor. what are some good ones that are fairly inexpensive? I have a Nvidia GeForce 7800GT 256mb right now
Message was edited by: jrgphotography

Hi-
Fairly inexpensive? That's a relative consideration.....
All OEM cards support the 30" ACD at 2560 x 1600 native resolution.
Only one of the ports on each card id dual link, with the other limited to 1920 x 1200.
The Geforce 6600 LE is the bottom of the pack, with the 6600 (256 MB) being only slightly better.
The 7800 GT and the Radeon X1900 G5 Edition are about equal in performance, and are two desirable cards for performance graphics.
Both have a dual link DVI for the 30", and both have the necessary horsepower.
I can't find a retail Mac edition of the X1900, but this flashed Radeon X1900 is cheap and has two dual link DVI ports.
But, since you already have a 7800 GT, you only have one real option left. the Geforce 7800 GTX.
http://www.barefeats.com/mutant4.html
The absolute pinnacle of performance for the PCIe G5 is a flashed Geforce 7800 GTX (512MB).
These cards have 2 dual link DVI ports to support 2 30" ACDs.

I suppose, depending on your usage, a Quadro FX4500 may be an option.
There is a link on my page to help determine if that is a better choice:

DVDSP 3 on PowerMac G5 Quad Processor

Hi,
I have installed DVDSP 3 with the upgrades on my PowerMac G5 (Quad Processor) running OSX 10.5.8. The installations runs smoothly without error.
However, when using DVDSP3 it crashes frequently. Sometimes when I try to preview the project or when working with assets.
I tried installing DVDSP3 on a bootable external drive running Tiger (same computer), but encountered the same problems.
Has anybody had any success running DVDSP3 on G5 hardware? Especially a quad- processor model?
I installed the product on my G4 (450MHz AGP graphics) and it runs fine (no crashes) albeit slow.
SyB

do a clean install:
back up work files to CD or external drive
insert the Mac OS install CD and select clean install from options menu
this formats the drive and installs the Mac OS
copy over the saved workfiles
re-install applications from original discs
up date as necessary
takes about an hour and a half

AMUG PowerMac G5 Quad Review

Hi Guys,
Those PowerMac G5 Quad users that are interested in upgrading or adding hard drives to a PowerMac G5 Quad may be interested in the results posted in the AMUG Quad Review. In addition, if your PowerMac G5 came with a LG GWA-4165B SuperDrive you may wonder how it compares with the Pioneer 110 or 109. The article compares all three burners and discusses the slow RIP rate of the LG SuperDrive.
For those paying an electric bill each year higher than the cost of a computer you may be interested in the Quad energy usage comparison section of the article.

Can I upgrade a PowerMac G5 Quad to an Intel chipset?

I am about to receive a hand-me-down PowerMac G5 Quad (model: powermac 11.2). However, I really need to run 3D modeling software like Rhino or Solidworks and thus would need to be able to load bootcamp.
Is it at all possible to bring the tower to an AppleStore or licensed repair business and have it upgraded to an Intel chipset for running bootcamp?
Is there another option I don't know of, for running windows apps on this mac pro?
Thanks

If you want to run Windows apps on that machine, you can install Virtual PC. I used to do it and it worked (although it took a bit to set it up and you need a copy of Windows). Also, be mindful that you'll only get about 1/2 of your processing speed in Virtual PC because of the emulation that's going on.
If you really need a Mac Pro, sell it (or trade it) and buy a used 1st generation 2.66 Ghz model. They're pretty reasonable now at about $1000 on the low end.
Hope that helps.

Powermac G5 quad - where ist the SMU-Reset Button?

my G5 quad is very fast, but too loud. The Main Logic Board Backside Fan increases speed after maximal 5 Minutes up to 3000 rpm, even if the quad really does nothing. I tried to reset the SMU by removing the power cord, but no difference.
An Apple instructor sent me this:
"To reset the SMU on a Power Mac G5 (Late 2005) computer, either use the steps listed above for the Power Mac G5 (Late 2004) or:
Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
Open and remove both the metallic outer door and the inner plastic air deflector.
Remove the fan assembly immediately to the left of the processor module.
Press the SMU reset button on the logic board.
Replace the fan assembly, air deflector, and outer door.
Turn on the computer."
…but I can't find the SMU reset button. Can anybody help me?

Hello
Choose "turn off" in the Apple menu, unplug the power cord, open the side door, unplug the lower fan, put your hands on the Quad Tower Case before you touch the SMU Button, then push the button only one time.

PowerMac G5 Quad - 2 issues that require your assistance ...

Hi Everyone ... I used to hang-out here a few years back under the handle KentZ, but I can't get back into my account for the life of me ... guess I have to start fresh.
I've been experiencing a few problems as of late with my PowerMac G5 Quad and I'm hoping someone may have some insight. I've tried the obvious "solutions", but please mention them, just in case I missed something - no such thing as condescension on this thread!
1] Fans - I'm not one to complain about fan noise on this machine, though I do have one weird issue. Upon start-up, the fans sound strained (can happen randomly) as though I'm running a small batch process or something. If I then go into sys prefs/energy saver/options and cycle the processor performance from highest to reduced and then back to highest, the fans drop back to idle speed. Works every time, but why is this happening?
Here are the stats:
All CPU fans are around 1455-1500 rpm and the radiator pump is at 3600 rpm. Drive bay spins at 1000 rpm, expansion slots at 1560 rpm, and MLB fan spins at 1100 rpm.
AFTER I toggle the energy saver/options:
All CPU fans are around 970-1000 rpm and the radiator pump is at 1250 rpm. Drive bay spins at 1000 rpm, expansion slots at 1560 rpm, and MLB fan spins at 1100 rpm.
Something to do with the CPUs ...?
2] The more serious issue: system hangs. Generally, when I'm doing something that's graphically intensive: expose-ing a lot, happens all-the-time in Aperture, happened tonight twice while watching an imbedded video online. Usually, the cursor still moves around and sound may continue, but the system is completely frozen and I have to do a hard reboot. Sometimes it happens when I'm nowhere near the machine. Any idea what this may be? I ran a RAM test a while back and all appeared OK.
Thank you everyone for reading and/or commenting.

Hello KenZ, and a warm re-welcome to the forums!
I can't get back into my account for the life of me ...
I've seen a few of these and asked, highers ups have mentioned "User Error", but I don't buy it myself.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for action in Safe Mode...
Reboot, test again.
While it can still can be HW such as Video Card, Airport, etc., If it only does it in Regular Boot, then it is some 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check System Preferences' Other row.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
I ran a RAM test a while back and all appeared OK.
Unfortunately, the only time you can trust a RAM test if it reports an error, not if it doesn't, seems OSX "Tests" the RAM more than any test.
