Dual Processor problem

I have been fighting with a cpu problem. my FW800 1.25 dual only works when pressure is applied to the bottom of the cpu, ie: a little "padding" between the MB and cpu around the 2 large chips. i have a sneaking suspicion the technique used to solder them to the daughter card, the ball grid array, has failed. has anyone had this issue or is this known at all?
i know the MB is good. i have tried other cpu's in my machine with no issue.
(in a related issue, ibook's suffered the same fate from this soldering on the video chip)

Hi Jade8503, and a warm welcome to the forums!
After changing CPUs you need to calibrate everything for one, look for Apple Service Diagnostics, ASD 2.6.3 I think, not sure which G5s that is for actually, but it's a start.
2.5.8 should work on that machine as well.

Power Mac G5 dual processor problem

So I've got a Power Mac G5 Dual 1.8Ghz that I bought used that only had one processor working. When started up, the screen hangs after the gray start up screen. I figure replacing both processors would fix the problem. Having bought 2 new processors, I installed them and now the computer won't boot at all. The power light comes on but doesn't stay on, the fans spin but nothing comes up on the screen. Is this a logic board problem? Any help would be appreciated.

K8T master 2far dual processor problem

has anyone installing a second opteron had a similar problem?
diagnosis:
the system works fine with one 242 processor, prior to instaslling the second 242 processor i turn off power using the PSU switch, i install the second processor and then turn on the PSU switch at this point the cpu fans and the system fan spins up for a second and then stop. The main atx on/off switch does not now work!! however after a few minutes it does and then the fans start up at full power and keep running. There is no display signal and no sounds of the system booting. Taking the second processor out allows the system to work normally.
What the hell is going on could there be a short induced by the second processor or something, please help before the whole system gets thrown out of the seventh floor window, closely followed by me.........
AAAAAAHHHHHHHH.........SPLAT.......too late?

let me know first so i can be there to save the computer
are the cpu's identical ?
are you mounting the cpu heatsink correct ?
do you use thermal pad or paste ?
i dont knwo much about your mobo but is there any jumpers you need to change ?

Urgent : UI refresh problem on dual processor or hyper threaded machine

Hello,
I am developing an applet that displays a set of tabs to the user. Each tab contains JLists.
When user selects from any of the JList(s), all lists are updated to reflect what is still available for selection. Number of elements in the list can be as large as few hundred thousands. This all works fine on single processor machine.
However, when running same on dual processor or Intel hyperthreaded processor, lists are not updated correctly. What I meant is that, for example, if a list originally has 100 thousands elements in it, then when I select an element from it, list is updated with available elements.Assume there are only 2 thousand elements available after above selection.Everything is fine so far, but when I de-select my selection, list is suppose to be updated again with original 100 thousands elements displayed again. The real problem is list indeed gets updated properly but few elements from list are not visible on the screen. However, If I minimize the browser(as it is an applet) and restore it again, all elemnets within the list are displayed correctly. Any help will be highly appreciated.

When your JLIst refresh occurs, the items are loaded into the JList from some other Object right? Nt knowing more about your code, I can't say exactly what that would be.Yes, you are right. Let me explain in breif about the architecture of the code.
I have a class,say CatPanel, that extends from JPanel and has BorderLayout with JList (wrapped in JScrollPane) in the center.
The main GUI class controls all such CatPanels.So, when the list is to be updated, GUI class invokes a method from CatPanel with Vector of elements to be inserted as an argument. Elements are inserted using setListData method of the JList.
If I'm right, the this might explain the behavior you are seeing. In a single processor environment, the data >is not cahced and therefore everything is fine. When you go to the dual-processor machine, the threads >have their own caches and are not always in sync. When you mimize the window and restoer it, this could >trigger a resync of the cache.Is there a way to trigger such synchronization?
One thing I'm not sure about is, when you return to the 'main' list, do you still see the selected sublist or >the main list with some elements missing? When a list is updated as a result of de-selection, few elements from start of the list are not visible.
I can see all other elements by using ScrollBar. So, if there are some selections that belong to the begining portion of the list, then selected sublist is not visible.
Let me explain with following example. Assume that with current selection, I have 100 elements in the list and all of them are visible on the screen. Now as a result of de-selection, suppose now the list should contain 200 elements rather than 100 elements. So, what happens in this case is that if first 50 elements are not visible in the list then I can see blank space corresponding to first 50 elements at the start of the list followed by remaining elements. I tried overloading paint method of an element that is actually inserted into the list, but still the result is same.

Z800 dual processor Booting Problem

Hi there,
I got a Z800 dual processor , I tried to operate the motherboard with CPU 1 only without installing CPU 0. now when I turn on the device. the fan of the case spin at maximum and RAM fan doesn't spin. besides bios screen not loading. is that mean my motherboard is gone. or could be bios got corrupted.
Thanks

What is causing a PowerMac G5/2.3GHz Dual Processor sudden abrupt shutdowns

Hi all
I am posting in hope that someone out there can help me solve this very puzzling problem.
The machine: A PowerMac dual processor G5/2.3GHz (early 2005). 1.5G RAM. 250G HD. SuperDrive. Radeon 9650.
The problem: When under some load, this machine will suddenly and abruptly shutdown as though someone pulled the power cord. There is no warning. Just a soft click, and it powers off. The machine can be manually restarted after the sudden shutdown with no problems.
This problem is very replicable. (eg go to a particular website, play an embedded video, and boom, the machine shutsdown. Each and every time.) It was replicated at an Apple Store and at two Apple Authorized Service Providers.
System.log said "PMU forced shutdown, cause = -122"
Before the sudden shutdown, the machine seemed to be operating normally. The fans did not noticeably speed up. Activity Monitor showed no more than 50% CPU activity for each CPU. Temperature on both CPU was around at 70C before the sudden shutdown. Temperature and activity on both CPU goes up and down in tendem.
If I use the Energy Saver system preference to change "Processor performance" to "Reduced", the problem goes away. (As measured by going to the same website and playing the same video. Even playing 5 videos simultaneously did not cause a sudden shutdown.)
What have I done #1: I have reformat the hard drive with a 7-pass security wipe, followed by a clean-install of Tiger which was then brought up-to-date using Software Update. I then installed Safari 4.0.3. No other software is on the machine except Tiger and Safari. (Later installed Hardware Monitor to get me a handle on the temperatures.) The problem persisted.
What have I done #2: I then installed a new PRAM battery and reset PMU using the switch on the motherboard. Resetting the PMU also resetted the PRAM. The problem persisted.
What have I done #3: I then took the machine to an Apple Store. They found that they can replicate the problem easily. But, after 3 days of running the Apple Service Diagnostic, the diagnostic software didn't find any problem. They also did a thermal re-calibration. That didn't help either. Without an error code from the diagnostic software, the only "solution" the Apple Genius offered was to start swapping CPU, power supply and mother board at my expense. And even then, he has no idea which component to start swapping first. (Two independent Apple Authorized Service Providers offered the same non-diagnosis and roughly the same "solution".)
Has anyone encountered such a problem before? What was the solution?
How about an educated guess as to what's wrong?
I want to, if possible, and if reasonable, repair this machine.
Thanks in advance.
Lara

This sounds almost exactly like the problem I have. My G5 is also an Early 05 2.3G. I tried every tip I found on the forums from UPS vs. wall socket to stock RAM vs. 3rd party to booting from external HDs, etc.. I currently have 10.5.8 on it and it's running using the "Reduced" processor setting in Energy Saver prefs.
I have also made a trip to The Apple Store where the AS folks ran their diagnostics but were usable to replicate my problem. I understand they "can't fix it if it ain't broke".
Aside from the "Reduced" setting work-around has ANYONE actually solved this problem definitively? Although I have no interest in spending $1000 to fix this, I can't imagine disposing of it on Ebay.
Assuming this is a hardware issue, this would mark the first insurmountable failure of any of the 10 or so Macs I have owned.
Anyone? Anyone?

CHUD on a dual processor MDD running Leopard (10.5.8)

I finally got around to installing CHUD today and am wondering if some of you folks who have used it for a while might have some easy answers to a few questions.
I first tried version 3.5.2. It installed, but I couldn't adjust any of the settings. I then read on japamac's site that some MDD's could use 4.4.4. I installed that version and it does work (In fact, I'm posting this with one processor tied behind my back). However, there does not seem to be an option for nap mode.
Also, after I toggle between single an dual processor mode a few times, performance in dual mode seems to take a big hit. A restart solves the problem, but I'm wondering if this is normal.
Is there any way to get nap mode to work in a dual cpu MDD running 10.5.8?
Is there any way to get it to stay in single CPU mode when it wakes from sleep?
I read through the discussions at xlr8yourmac before posting this. It appears that some people have been able to get nap mode to work under Leopard, but they are not always careful to mention exactly which version of Leopard and CHUD they are using.

Hi-
When installing CHUD, it is also necessary to run CHUD remover to deinstall previous installations.
If not deinstalled, odd stuff happens.
3.5.2 is the one for dual processors.
Other versions have mixed dual processor support.
This is one of the claims that 4.4.4 works, but I have lingering doubts
http://discussions.apple.com/thread.jspa?messageID=5974655&#5974655
I may need to edit my blog page.....
It takes a script for automatic Nap enabling in a dual processor machine with 3.5.2.

"Inconsistent cursor cache. Out of range cursor" error on dual processor multi thread

I have a C++ with Pro*C++ COM object running on a Win2000 OS on

Table A and following errors comes from a Table B having a
foreign key on Table A.

Trying to set up a new Lacie Porsche 9220 external drive on a 1.25Gb Dual Processor G4 Mirrordrive running OS X 10.5.8

Labview and AMD 760 MPX Dual Processor Chipset?

Anyone have any experience with Labview on a dual processor motherboard with the AMD 760 MPX chipset [and, of course, Athlon MP 32-bit CPUs]?
Any gotchas? Any known incompatibilities?
On the hardware side, has anyone had any problems with NI-DAQ or NI-DAQmx?
Any info would be most appreciated. Thanks!
PS: Especially interested in opinions of e.g. Tyan Tiger MPX -vs- ASUS A7M266-D [or any other boards you're familiar with]. Thanks again!

It's years I use 6533 high speed digital i/o making 2mhz output without problems on any hardware.
Today I'm trying to use a Tyan Tiger MPX (double AMD)and .....it doesn't work at all. It's surely a problem with the pci bus, dma and bus master. The total speed is 200KB/sec instead of the desired 2MB/sec. I tryied more than one serial number so the problem is a motherboard's design problem.
I dont use labview but only nidaq drivers and C language.
Now I'm changing the motherboard...at least until someone explain me how to work around the problem.
No problems with MSI and Intel motherboards.

Dual processor / performance

Hello world!
Is anyone running a dual processor or dual core procesor with a jmf application or even JMStudio? on Windows or Linux.
Could you tell us
1) The sort of performance gain you get compaired to single cpu
2) The type of cpu you use
3) Do you experience any cpu related problems worth mentioning
Thanks for your input,

ok here are some tests that seem to clarify things and contradict some of the previous text on this posting.
We created a number crunching cpu intensive basic java application (see code below) and the result are as follow
machine 1 single 3ghz Intel P4 cpu windows xp
machine 2 dual 3ghz Intel P4 cpu (2 X 3ghz ) windows 2000 server
1 single thread
machine 1 took 17 seconds at 97% max cpu
machine 2 took 33 seconds at 50% max cpu
2 concurent threads
machine 1 took 35 seconds at 97% max cpu
machine 2 took more than 70 seconds at 97% max cpu
So it seems that multithreading or not for java, a dual cpu on windows is a waiste of time.

Need? firmware update on 1.8GH Dual processor G5 PwrMac for Tiger upgrade.

Equipment: refurbed 1.8Ghz PowerMac Dual processor, running OS10.3.9 Panther just fine. CPU's: PowerPC 970 (2.2); Bus speed: 900MHz. Boot Rom: 5.1.4fo
I read on Forums of problems some single processor 1.8 G5's have had with firmware updates prior to attempting to run OS 10.4.3 . I was about to install Tiger 10.4.3, now wonder if it will open a can of worms if I update firmware prior to the install. The reported problems were on machines with bus speed of 600mHz; as mine has a 900mHz bus speed, am I not likely to encounter that difficulty? I would appreciate any input from those familiar with this issue. Sounded like some of the affected owners were really stuck for a long time with that particular problem. Thanks.

Since you did not specify which particular model you have, it's hard to tell you whether a firmware update is even required. Open System Profiler and in the summary look for the Machine Model. If it's 7,2 then 5.1.4 is the current firmware version. If it's 7,3, then 5.1.8 is the current firmware version.
