Thermal issues with PowerMac G5 Dual 2.0 Processor

I've been having issues with my fans running super loud for no apparent reason. I have been told that my thermal meter for one of my processors has gone bad and that I have to replace both my processors at a cost of over $800! I am simply wondering if there has been any other issues even similar to this one or if anyone can tell me if I really do have to have both processors replaced for this situation. Also, I am wondering if anyone knows how to run the processor diagnostic where I can view my computers feedback for myself.
I am a starving designer and desperate to fix my biggest tool. Please let me know of any possible suggestions or cheap fixxes. If there is no way around replacing both processors, please let me know of any good mac processor retailers! Thanx all!

Who has told you what the problem is? Has the G5 been in the shop?
Is there a pattern to the loud fan noise?
Is there a red light on inside?
How warm is the room?
Is there a dust build-up inside the G5?

4GB memory on new MacBook Pro Retina 13 with 2.4GHz dual core i5 processor &128GB flash storage

Hello,
I'm completely new to the mac world but I'm fed up with pc's and all the insanity with processor problems, viruses, etc. I'm seriously looking at replacing my HP laptop with the new MacBook Pro Retina 13 with 2.4GHz dual core i5 processor, 4GB memory (RAM) & 128GB flash storage, OS X Mavericks (not sure which version). My concern is whether this will be reliably & consistantly fast & smooth both in desktop apps & internet use. I don't need it to do somersaults or anything too advanced. I would mostly be using Pages & spreadsheet apps & internet. It would double as my daughter's computer for cyber school so it's crucial that it runs quickly & efficiently. If she can't complete everything on time or log in to her online sessions because of a computer issue we'll be up a creek without a paddle since this particular cyber school's tech department is still working off of pc's running Windows XP. My father, thus far a pc user, thought I should consider moving up to 8GB memory but I was hoping that with flash storage being faster, I would be able to avoid the extra $100 for the upgrade to 8GB. My biggest fear is finding myself as frustrated & angry as I am now with all of my pc's, ready to take a sledge hammer to them because they take forever to boot, launch apps, internet or do just about anything (that is if they're even fuctioning at all- not joking). Does anyone have any advice or input? Thanks!!
P.s. On Apple's site I found a refurbished late 2013 model of the MacBook Pro Retina 13 with all of the same specs as listed above (4GB, not 8GB), running OS X (doesn't say which one) but for a bit less than a brand new one. Is this the same model as what they're currently selling new in their store or did they just upgrade everything to match what is being offered in the current "new" model? I realize this may be a dumb question but I can't seem to find anything online indicated that Apple has released a model newer than what was released late last year (October 2013, I believe), except that the model released then came with SSD storage instead of flash.

No computer is fault free but Apple MBPs have a good track record. In those cases where problems do arise, Apple has the best support in the industry.
A MBP with 4 GB RAM with the SSD storage should be adequate for your needs.

The latest MBP models came out in October 2013, so it will be the same, with the same warranty and telephone support. The difference will be that the price will be less and it will be delivered in a plain white box.
I have purchased three MBPs from the refurbished section. I have never been able to detect any cosmetic differences and will go that route again.
Ciao.

WRT54GX2 SRX200 thermal issue with internal Ethernet switch engine? Issue with DynDNS?

The WRT54GX2 SRX200 had been working for 2 years. Last week it started to drop LAN/WLAN i.e. all Ethernet connection are up for about 20 seconds, then drop, comes back within 10 seconds then drop again after 20 seconds, etc. Shutting off the WRT54GX2 for a while will give 5 minutes of service, but the cycle will start again. Power supply is operating OK. I suspect a thermal problem on the Ethernet switch engine: it has been hot in San Jose and the wiring shelf reached 85*F. The other issue is that DynDNS flagged the WRT54GX2 SRX200 because it updates IP too often e.g. update on a timer ?
I replaced the SRX200 with an older WRT54G V5 that works well in the same spot, and is 'verified' by DynDNS.

Whats the current firmware installed on your Router?
Try to download the latest firmware of your router from the linksys website and upload it on your router, once the firmware is uploaded then you need to reset your router and re-configure all the settings on it from scratch.

Powermac G5 Dual 2.0 - Processor Issue

Well, I've finally had something happen to this beloved G5 of mine after 5 years.
For no reason, the rans started kicking in, spinning up and down, very frequently.
Decided to give it a good cleaning (which I do at least once a year).
1. Sprayed out all dust
2. Reset the PMU
3. Reset the PRAM/NRAM
4. Ran Apple Hardware Test (gulp).
Error Code:
2STH/1/2: CPU A AD7417AD1
Guess it's a thermal failure in one of the AD modules in CPU A.
Question:
Is it safe to keep running this "as is"? Also, does this really mean that I need to buy a new processor?
Thanks for any assistance.

I'm pretty certain you only need to run the thermal calibration if you remove a processor.
Looks like this problem has changed gears, anyway.
Hardware tests do not bring back a processor error. Now, everything is linked to the video card failure (has failed on the hardware tests).
Cleaned the card and heat sync real good, as well as reseating it. Same issue.
Screen "dissolves" on both my ADC Cinema Display 20" and DVI HD Cinema Display 23".
Has to be linked to heat as it's fine when you start up, and then everything slowly dissolves.
I have an ATI 9800 Pro 128 AGP which is impossible to find. It was an upgrade direct from Apple with the ADC/DVI connector.
I hope it's just the card and not the start of the end; I'd hate to dump this beloved friend, but I'm not willing to invest a ton of money into putting it back to square, especially since first gen g5's seem to dying all over the place.

Compatible issues with PowerMac 8600/300

I am currently attempting to make use oif a NI board for experimental purposes, however I am unsure in regard to it's compatiblity. I'm referring to Nation Instruments Board NB-M10-16X (assy: 180675e-12).
I currently have a PowerMac 8600/300 which i would like to install the the card into. However, if this is not compatible, I would welcome any suggestions.

Hello;
That board is supported on Mac OS. Make sure to download the latest NI-DAQ version that support Mac OS, from www.ni.com/support.

Issue with dock and dual monitors

After unplugging my MacBook (Late 2008) from my Samsung External Monitor, my dock disappears and requires a "killall Dock" in Terminal to reappear. Does anyone know how I can fix this? Thanks.
PS- Running 10.5.8 and it happens all the time.
Thanks again.

could have something to do with how you are sharing your desktop b/t the laptop and the monitor... try resetting your monitor to "clone" or resetting your home screen to the laptop BEFORE unplugging the external monitor--

Powermac G5 Dual 2.0 thermal calibration issue - Fans on full blast!

Hello, I need to do thermal calibration on powermac G5 dual 2.0. Does anyone know where to get ASD dual 2.5.8 discs? I'm afraid to run the computer with fans on full blast. Any help would be greatly appreciated!

Hi, ASD has never been available to the public, but even if somebody had any clues or other suggestions, you & Apple are the only ones that can see your eMail in your profile.

Powermac g5 dual 2.0 fans run too slow, overheats the freezes.

My G5 processor fans seem to always run at the same speed, 300-345 rpm. I know this deviates from the common fan over- revving issue with powermacs but recently it now will freeze up and I get the grayed out curtain telling me to power off with the power button. I've monitored the temps and noticed that when running multiple apps or just one like Aperture the temps begin to increase and when they reach 145-148ºF it freezes up. I've repaired permissions, reset PMU but nothing. Is there any way to adjust or rest fan control in console or is there an aftermarket auxiliary fan I can use to provide better cooling? Oh, yes I've vacuumed and blew out any dust on the processors.
Thanks
Pete

Robbert,
Thanks for your reply. I decided to try a fix to cool the processor temps and it seems to have worked albeit rather unconventional and honestly after dealing for over a year with an out of control dual 2.7 (my previous computer) until it just self destructed, I really had nothing to lose. I went to Walmart, bought a $15.00 3 speed fan which interestingly is same color as the powermac and is a cylinder type with two exhaust outlets that cover the entire motherboard height. Removed the clear plastic air deflector but covered a piece of paper with aluminum foil and inserted it into the tab slot to fool the computer. Opened CS3, Aperture & Corel paint. Temps quickly went to 137+. Turned on the fan to high and saw temps drop to 120º. Opened several more apps to try to cook the processor but highest temp was 125, Kept running all apps for hours and no shut down. When just running Aperture I turn fan to low. I have not been able to run Aperture for more than a few minutes fro months so this to me is great. I also noticed that when I just removed the air deflector temps went down about 4º. As I said I had nothing to lose and I think it's an accepted fact that a majority of powermacs had/have serious cooling issues. I'm happy.

Powermac G5 dual 2.5 issues!

I purchased a pre-owned Powermac G5 Dual 2.5 ghz. It has 4gb ram and is running Mac OSX 10.5.8. Very shortly after I purchased the computer I had a crash and couldn't get it to start back up. I tried to re-install software and it would go part of the way thru and crash on the install every time. I started the machine in target mode and hooked it to my old trusty G4. I was able to install the software that way with no issues. I then went back to the G5 and tried installing updates, but part of the way thru the updates it would crash saying the update was possibly corrupt, ( these were straight from apple so I doubt that ) thus leaving my g5 unable to restart because of the partial software update. I did the target mode again, this time installing all of the updates using my G4. After all was said and done, I was back to where i had started when i bought it. I now keep to be getting freeze issue with the machine. I can be online using safari and all of a sudden I get the spinning color wheel. When this happens I can not even force quit the app, it will just sit there spinning away. Tonight i tried opening firefox and it started up and ran for a few minutes before freezing also. A few days ago I had tried to burn a dvd using toast, and that app also froze up and would not let me force quit. I have not had any issues like this from my G4, and after trying resetting the SMU, PRAM and many many hard restarts, I am no closer to knowing what the issue could be. Any help or ideas for me to try would be much appreciated. Thanks, Mike

Have you blown the dust out of it since you got it?
Possibly a temperature problem or bad RAM/RAM slots.

PowerMac G5 Dual 2.5 - Only Boots with Side Cover and Fan Guard OFF!!

I have the strangest problem with my PowerMac G5 Dual 2.5. This has been my Pro Tools rig forEVER.
At some point early last year, my Mac wouldn't boot. It would not see the hard drive, and would show that dreaded alternating icon in the middle of the screen indicating as much. I tried resetting, tried power off/on, tried resetting PRAM. Nothing. I took the cover off, and fan guard off to get at the hard drive. Verified the data and power cable were seated in hard drive. Cover still off, I booted up the system. Voila!!! Booted right up like nothing was ever wrong. I put the cover back on, and went about my business, passing it off as a one-off power glitch (the power in my house ***** rocks). Next time I rebooted the Mac, the exact same thing happened.
I can repeat this at will. If I leave the cover on, the system will not ever, ever boot. The minute I take the cover and fan guard off, causing the fans to spin at max speed when turned on, the system boots without issue. So, I reset PRAM and PMU. I even tried replacing that green/white cylindrical battery on the motherboard. Reseated power/data cable on hard drive. ****, I even tried a different hard drive and memory (explained below). No change.
Since then, I have relegated this system to the emergency backup system, and procured Dual 2.7 G5 PowerMac. I transferred the pro tools cards, hard drive (without formatting it) and memory (8 GB) to this new 2.7, and have not had a single, solitary issue with it. So, I know it's not the hard drive, memory, OS install, or Pro Tools cards.
What in the name of the Apple Gods could be causing this issue? Any ideas at all?

Hi Chris,
Good info & work so far, but indeed strange, only thing I can think of is something to do with that little switch for the fan cover... near the bottom as I recall, but it may be some kind of short in it's circuit.

Powermac G5 Dual 2.0 Ghz machines made in 2004 ship with Tiger or Panther?

Reason I'm asking is I bought this mac used. The dude forgot his password, the machine freezes up intermitently, so I think I should reload the OS. However he forgot to give me the OS X system disks that come with it. He's been avoiding my phone calls about this. So I'd love any help anyone can give me on this system freeze up and password issue. Thanks!
Here are the specs:
Machine Name: Power Mac G5
Machine Model: PowerMac7,3
CPU Type: PowerPC G5 (2.2)
Number Of CPUs: 2
CPU Speed: 2 GHz
L2 Cache (per CPU): 512 KB
Memory: 1.5 GB
Bus Speed: 1 GHz
Boot ROM Version: 5.1.8f7
150 gig HDD
Powermac G5 Dual 2.0 Ghz Mac OS X (10.4) 1.5 ram, 150 gig hdd

Other than having to buy Tiger OS, there is no reason not to. I have Tiger on even older 2003 G4 MDD and Blue G3 (Yosemite) still running 10.4.9. Well, I don't use the G3.... but I 'could' - and run okay for basic stuff.
The only things to consider is that you have updated your software and such to run on Tiger (can't see that being an issue 2 yrs after Tiger shipped, unlike Apr 2005 when it was a 'learning curve' for all of us).
I would backup, and then use Tiger DVD to re-format (Partition) and install, and then import or merge my files afterwards. Anyone with G5 from prior to Apr 2005 really is more likely and should upgrade to Tiger than stay with the original OS.

Issue with HP Z820 64GB RAM and dual Quadro K4000's and rendering and playback performance

I'm having major issues with performance on my system (running windows 8.1. Premiere CC 7.2.2). My friend in the office here has a Mac Pro (2013) with 6 core cpu and dual D500's and I have dual Xeon 2665's and dual K4000's.
The problem is that he can export twice as fast as me on mercury software and almost 3 times faster on Mercury GPU. He can also add twice as many affects before his system drops frames (using same settings and video file). When I go to GPU-Z my gpu's are hardly working with GPU export selected... with software only my CPU's get to 60% load max whereas his CPU get's to about 84%. Am I missing something? I know the D500's are almost the same as W8000's (and he has two), but dual K4000's shouldn't be that far behind? And how does selecting cpu exporting get him an export time of 6 minutes compared to my 15 minutes when I have a 32 threads to work with??
Am I doing something wrong? Have I got a setting somewhere that is causing this that I might have missed? Are dual D500's really THAT much better than dual K4000's? AND HOW is my 7k+ machine that much worse than his £3200 mac?
Please help. I'm losing my mind here!
Thanks
Edit - Would just like to add that the video files we are using are pro res 422 and that I have the latest bios and latest nvidia performance drivers

That HP Z820 should kick the Mac pros butt! For example we run Autodesk Flame systems ( 150k software) on the Z820's with Quadro 6000 cards and they fly. We also had a new mac pro in for testing a few months ago w the dual fire pro cards all decked out and it was crap next the the Z820. Of cource the new MP cant run allot of highend software because of its lack of nvidia support and the firepros lack of open GL but we did run premier and smoke etc on it for testing. ( Although i thought it looked cool the total lack of exandability and nvida support was to much so we sent it back). Graphic workstations need PCIe expandability and a choice in GPs.
Anyhow here are a few observations:
-Software being used will dertermine the hardware purchased,
-The dual xeons at the much lower clock speed are meant to work 24/7 like a lamans endurance race, not a sprint race. Better to get highest frequency xeons.
-Having dual CPUs with all thoughs cores will only work with a software that is properly mulithreaded, premier is definetly not one of those softwares so you not getting any advantage.
- the advantage to Quadro cards are much more noticable in 3d tha 2d. If your running Autodesk maya, 3ds max or the recently disscontinued XSI you would be flying compared to the W7000.
-dual GPU cards do not preform at twice the speed. On average the second card gives about a 10 percent boost.
-At present ( and as akways) , nividia Quadro drivers are much more uptodate and bug free compared to ATI highend cards. This will inevitably change as openCL over takes openGL, until then Quadros are the clearly superior cards for those with DEEP pockets.
-I think you would have been far better off with a single Quadro 6000 vs dual K4000s. Also any higher end ATI firepro card would have worked since Premier now uses open CL and no longer needs openGL. Main advantage to Quadro at this point ( besides 3D ) is to be compatible with the most softwares and get the best and most optimized drivers. Firepros will work properly in far fewer softwares at this point but I can see a day over the next few years this may change but not as of yet in 2014. So his W7000 wins this sprint race in this single simple example but in most any other situations your cards will actually work and win. I like saving money like the next guy but I even purchase Quadro cards for my home use and experimenting, but Im not a gamer.
-FYI: Cuda core count no longer is true measure. For example older Fermi cards worked at twice the frequency than the newer kepler architecture so in effect today you need double ( actually more) the amount of cuda cores to equal the older cards. Also the true compute power in the new Keplers is also much inferior to the older cards. Its all creative advertiseing today more akin to creative accounting / smoke and mirrors. What im trying to explain is when people read the charts that show the cuda core count and say the higest is best is completely not true. It may have the most "cores" but it will not render correctly, double percision is missing, colors may pop, anti aliasing is inferior and inconsistant, interaction ( most important) and shaders will be buggy or missing. There are very good reasons people spend money on highend Quadro cards but the charts and reviews generically speaking never understand or can even test for this stuff.
-Even given the above scenarios your Z820 should be killing your competition. Using a decked out Z820 is way overkill for anything CC. ( Kinda like driving an F1 to get groceries.) get your HP rep to come over and replace / test your rig. Its free and covered in your coverage.
I am CLEARLY not a tech guy as my talent in is creation and design but I overhear the tech guys talking.

Compatibility issues with Mac OSX Leopard 10.5 and Word 2004 11.6.3 on G5 PowerMac?

Are there compatibility issues with Mac OSX Leopard V. 10.5 and Word 2004 11.6.3 when installed on a PowerMac G5? I understand the Leopard upgrade is okay on the later Intel Mac, but what about my G5 PowerPC Mac?

I do not use Microsoft Excel much but when i do use it it works fine on my G5. my powerbook has excel to but sometimes freezes on the powerbook. but not the G5 so give it a try you can always uninstall it if it does not work good

Issue with new dual band APE

I am having an issue keeping a good connection on the 5ghz channel with my new dual band airport extreme. Let me explain my current network. I just purchased a new APE. Airport utility shows it as AirPort Extreme Dual Band II with 7.5.1 firmware. I have it running a 2.4ghz G network and a 5ghz N network. In the basement I have my older APE which is a Airport Extreme N with gigabit ethernet (7.4.2 firmware). It is set to join 5ghz network from the dual band and then acts as a hub to my gaming Windows PC, ps3, and xbox. The 5ghz network is very spotty, it will work fine and I can browse away for about a minute and then it will just stop. My laptop and ipad will still show full signal strength, safari will just end up timing out while waiting. If I move them over to the 2.4ghz G network everything works fine, except of course file transfers which are slow because of being on the G network. Also should the older router be on a higher version number of firmware? I have tried checking for updates on both.

+Something seems off.+
Absolutely.
At 2.4 GHz, the high noise level indicates that you are experiencing interference from another wireless network (do you see other networks in iStumbler?), cordless phones (could be yours or your neighbors', a nearby wireless security system, microwave interference...lots of possibilities.
iStumber may not display "hidden" networks. Most modern routers (Apple included) allow users to "hide" their network, so it's possible that you may be experiencing interference from a wireless network that you cannot "see".
If you have cordless phones, you might want to pick a time when you can power them and their base stations completely down for a few hours to see if the wireless signal improves and noise drops on your network. Not much you can do about a neighbor's cordless phone or security system.
Experiment with different channel settings on your 2.4 GHz wireless as well.
Most cordless phone will not interfere with 5 GHz. I can't explain why your 5 GHz signal is so low..and the noise high..if you are close to the router and have line of sight between devices. Try a few different channel settings on 5 GHz as well.
Let us know what you find.

PowerMac G5 Dual 2GHz freezes any time, boots sometimes with one processor

Since two weeks I experience freezes at different up-and-runnng time. It could happen at grey startup screen (after a while fan goes wild), could be after some minutes working in a full booted user environment.
I run AHT several times, no error reported. When I took out all RAM except for Apple RAM, it still freezes at some time.
Now, by random, my machine starts sometime with only one processor and is stable for hours (only the fan runs higher and cpu load is most of the time near 100 percent). Activity shows one bar only, System Info says: Number of CPUs=1. I have no idea which processor runs and which "sleeps" deadly. iStat tells only about CPU A as having a temperature, the fans of CPU A run higher, but the fans of CPU B run also on a lower level.
The "U3 Heatsink" reads 65-70 degree Celsius. Is that (too) high?
Only once I got a kernel panic during verbose startup. It read:
"System failure: cpu=1; code =00000001 (corrupt stack)
unalined fram address: 0x00000001"
I am tempted to shut down one CPU with Open Firmware command, but will it be the defect one? At least the machine is doing something regular then, but is slow...
Any help is much welcome!
Yours, Whoopy

My PowerMac G5 Dual 2.0 also has this problem.
It all started one sad afternoon a month or so ago. I noticed that my computer was on and the fans were on full speed. As soon as I moved the mouse to shut it down, I got the wheel of death!
I had no choice but to do a force shutdown.
The next day, I turn my computer on and it just stayed on the gray screen with the dark gray apple, and no spinning thingy.
So once again, I had to force shutdown.
Pressing the 'Option' key did gave me the screen where one can select where to boot from; the main HD, booting CD, etc. but none of the worked.
When I chose to boot from my internal HD or from the restore CD it would just get stuck on the gray screen with the apple logo.
I pressed the PMU button = no change
I did a PRAM reset = it brought my G5 to life but then a few minutes later it froze and history repeated itself.
Did a PRAM reset again and this time didn't work.
Tried booting from my PowerBook G4 HD via firewire = frozen gray screen
When I pressed the 'T', i get the FireWire logo and I'm able to boot my G5's HD using my PowerBook G4. But when I put my G4 on firewire mode and try to boot my G5 by selecting the OS of the G4, I still get the frozen screen, so the problem is not with the HD.
One time I was able to boot my G5 from the 'Restoration CD' and I used the Utilities to Fix permisions, and repair the HD but still the computer would freeze and same old story.
Since I got this problem, It has work normal only 3 occasions but no longer than an hour until the fans go crazy and freezes.
I tried different memory sticks and no improvement.
My AppleCare expired on May, and my G5 went down 2 or 3 months after that.
This feels part of an strategy called "Get a(nother) Mac". Where comps are design to last just a little after AppleCare expires and then BOOM! no choice but to spend some serious cash on fixing it or use that money plus more to get one of the resent mac which have had some changes since one bought the mac that just went to apple heaven.
Anyways, I feel that the problem will be solved by replacing the two processors, heatsinks, or whatever they called it.
I took apart my G5 today and I'm not sure but it seems that the heatsinks might use some kind of gas to cools the CPUs or Chips and I think that gas is over.
Has anyone swap the heatsink units and noticed any difference?
Here's of the heatsink for the PPC G5 2.0
