Mac Pro 2009 8 core with an endless cycle while booting up

Dear all,
My Mac Pro 2009 edition (2.26 GHz,8-cores) is suffering from a weird situation which I can't solve, so I post the message and hope someone can help me to find a solution.
On Monday Morning, I found the rainbow cycle is running behind the screen saver after shifting my mouse. The Mac Pro was not responding (can move mouse), so I pressed the button for 5 secs to shut it down. Then, I pressed the start button and saw there is a folder with question mark on the screen. After looking several web pages, I realized that it might be the RAID is failed for some reasons. I used the OS X installation disc to boot up and found that the RAID card was not recognizing the original RAID 0 build while the RAID card was shown to be healthy. I decided to restore my system from the time machine (WD Green 2TB x2, RAID0), so I checked the content of the time machine and hoped that I can find since when the machine is not responding. Then, it was 5:36PM on Friday, the last backup (backup per hour). So, it has been freezed for more than 2 days right after I left my office! Anyways, I used RAID utility to rebuild the RAID 0 (1TB x 4) and started recovering the last backup. After 11 hrs, the restore had been successfully done, so I clicked the restart button. However, after booting up, I got a grey apple and a running circle below it. The loading screen remained for 10 hrs and wouldn't get in.
I sensed that there is something wrong. It couldn't be fixed by simply restoration by time machine. Therefore, I started exhaustively surffing the internet and looking for an answer. Here are things I have tried but didn't work:
1. Restoring from three different time points: last time point, 1 hour before the last time point, and midnight on Thursday. Not working.
2. Remove Mac Pro RAID Card and use Disk Utility to build SoftRAID 0. Not working.
3. Remove ATI Raedon 5770 and replace with the original GT120. Not working.
4. Use Apple Hardware Test from Application installation disc to perform both default and extended tests. Found no problems.
5. Replace SDRAM with the originial 6GB (1GB x 6) SDRAM.
6. Tried reseting PRAM (3 to 4 times each)
7. Tried reseting logic board by following the instructions from macusersguide (http://www.macusersguide.com/2009/06/reseting-the-logicboard/).
(*)8. I tried to boot from another HardDisk, which I installed Win7 on it a few months ago (including all needed drivers for the Mac Pro). It is an originial Win 7 and it works! I also tried to test the 4 HDs by using the windows experience index. I tried 5 times (1 disks individually and all 4 disks enabled). All tests passed.
So far, I can only conclude that the hardware seemed fine, and it could be a software thing which blocks me from getting into the Mac OS.
I have been working on this for 3 days, and I am really tried. Could someone help me addressing this issue? Is there anything I can do to test which part is doing wrong? Should I test more time points in the time machine? Should I just hand my Mac Pro to Apple retail stores and asking for fixing (apple care expired and they would charge fees..)?
Thank you so much

Frankly, if you want a reliable backup from which you can boot the computer, then don't use TM. Use a backup utility that makes bootable backups starting with the Restore option of Disk Utility. Here are others:

Mac Pro 8 core with boot drive cloned from MacBook Pro

I bought a Mac Pro 8 core and in order to avoid having to reinstall all my stuff, I cloned my OSx (tiger 10.49) partition from my MacBook Pro running vista (installed via bootcamp) to my new MacPro's startup disk. The disk works fine except that the MacPro will not boot to osx unless I use the option key and choose the OSX partition. If i just turn the machine on it doesen't find anything. I think it is looking for windows. What do you think?????
Also, if i restart from the os x partition on my mac pro it stops just before the lound bong sound and seems to be looking for the dvd drive. Any ideas??

Well, I've covered this extensively here:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3 or G4 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior (does not work), TechTool Pro (pre-4.5.1 versions do not work), SuperDuper (newest release works), and Drive Genius (untested) may not work properly on Intel-Macs. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
Basically the instructions you should follow are:
1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
2. Connect a Firewire cable between your old Mac and your new Intel Mac.
3. Startup your old Mac in Target Disk Mode.
4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
4. Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
/Home/Library/Preferences/ copy any preferences needed for third-party applications
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to another forum user for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
Written by Kappy with additional contributions from a brody.
Not knowing what you did when you migrated from your PB to the MBP, I can't really comment, but it's quite possible it didn't go as well as you think. Numerous users who migrated from PPC Macs to Intel Macs ended up with an Intel Mac that didn't work properly because Intel coded components had been replaced by PPC coded components.

Mac Pro 12-core won't boot Mac OS X 10.6 "Server" Install DVD

I have just received my new Mac Pro 12-core today.
I tried to boot from my Mac OS X Server (10.6) Install DVD with no success.
I WAS able to "upgrade" from the preinstalled Mac OS X 10.6.4, but I need a clean installation.
I first thought there was a problem with the internal DVD drive, but I could boot the provided Mac OS X Install DVD. I also tried to boot the "Server" DVD from a firewire external DVD drive, with no success. I even tried "target" mode, using the DVD drive from a Mac Book Pro, with no success.
The server install DVD is not corrupted, as I used it recently on my 2007 Mac Pro 8-core.
Please help.

FCS 2 -- Mac Pro 4-core or 8-core?

Been reading both the FCP forum and the MacPro forum and still not unsure which way to go.
I'm an avid Avid user (sorry about that) for many years and now making the switch to FCS2. My confusion lies in which configuration to get to best maximize FCS2-- Mac Pro 4-core with maximum RAM or Mac Pro 8-core with 6 or 8 GB RAM? The machine will be used 90% for FCS 2 so that's the main decision-making factor here.
Been reading articles about bottlenecks that make having 8-cores benign, but I find them hard to believe. Either way, the cost is about the same (the $$ saved buying the 4-core would be spent on more RAM).
Thanks for your time and advice.

With FCS the trick to maximising your performance is balance. Getting the balance right between processor performance, GPU performance, RAM and drive performance can often be a tricky thing. Unless you consider your system as a whole, any improvement in one area will often have little value.
At the price of the 8-core upgrade (more than 50% of a whole new one!) I would think you'd get far better value by going with a 3GHz 4-core system and maxing out everything else.

If you become a "power user" i.e. running more than one app at a time all the time.... The 8 processor machine will be faster than the quad... if not, they'll be similar in speed.
See: http://www.barefeats.com Rob there comes up with much the same conclusion. There are certain apps though that really shine on the octo... AE for example... and Certainly Compressor 3... big time...
I'd go with the faster machine figuring Leopard will make a big difference in the way it handles mulitple processor machines.

Mac Pro 8-core slow compression on MPEGs

My Mac Pro 8-core with 9GB of RAM is very slow compared to my G5 Dual 2.7GHz with 2.5GB on doing MPEGs... the problem only exist with MPEGs in Compressor 3 or 3.0.1. All other formats the Mac Pro gives the G5 a thrashing. I've read in here that many people have it the other way around.. that MPEGs are supposedly more multiprocessor capable.
Both with using virtual clusters (4 instances) and no virtual clusters I'm getting around 52 minutes on a DVCPRO HD 720/24p clip which is exactly 6 minutes in length. The G5 dual 2.7GHz with 2.5GB of RAM did this job in 21 minutes and 33 seconds.
On the Mac Pro I've erased my system and reinstall with just FCS2 on the system... still the same speeds. I've taken out the 2x4GB sticks.. still the same speeds. I've moved the 6 minute clip onto different volumes still the same problem. I've tried other DVCPRO HD clips.. still the same.
The problem only happens with the DVD 90-150 presets regardless of quality. Does not occur with the HD DVD presets or H.264.
Mac Pro configuration:
Mac Pro 3GHz 8 core
9GB of RAM (2x512mb, 2x4GB)
ATI Radeon X1900 XT with dual 30 inch ACDs
3TB of internal Hard Drive storage... one unraided 750GB for system files.. 3 RAID 0 for Scratch.
AJA KONA LHe capture card
Runiing Final Cut Studio 2 with compressor 3.0.1
G5 configuration:
Power Mac G5 Dual 2.7GHz
2.5GB of RAM (2x256MB, 4x512MB)
NVIDIA GeForce 6800 Ultra DDL with 23" ACD
250GB + 160GB internal Hard Drives.
Running final Cut Studio 2 with Compressor 3.0.1
Any help would be appreciated... I've tried everything in my technical powers to solve this one.

Made a new DVD: MPEG-2 custom setting with an average bit rate of 7.7Mbps... still slow... about 50 minutes to complete the 6 minute DVCPRO HD 720/24p clip. The compressor daemons are averaging around 60MB of Real Memory and 450MB of virtual memory. I really think this lack of memory usage is causing the problem. This only happens on the DVD 90-150 MPEG-2 presets. Any other format is grabbing at least 200MB per daemon... including HD DVD MPEG-2 and DVD MPEG-1. I will continue to test different settings and pray for a change.
Getting all compressord (Not Responding) for each 4 instances in the virtual cluster when I run the DVD 90-150 MPEG-2 presets. The batch monitor is still reporting progress. Real memory usage fluctuating in the 60's per daemon and around 450MB's for Virtual Memory. Compressor daemons not responding is a problem solely on the DVD 90-150 MPEG-2 presets.
No major difference in speed between CBR or VBR custom presets... memory usage still in the 60's per compressor daemon.
With Job Segmenting turned off & One Pass CBR... 20 minutes to job completion. The memory usage is around 65MB of Real Memory and 450MB of Virtual Memory. CPU activity on the one active compressor daemon is averaging around 460%.
One thing I am learning is that processor activity as reported by Activity Monitor is not a reflection of speed.

Why is Northbridge diode so hot on Mac Pro 8-Core 2009?

Hi,
I just run XRG (http://www.gauchosoft.com/Software/X%20Resource%20Graph/) to have a deep look for my Mac Pro 2009 and I discovered that the Northbridge diode is 70°C-80°C.
After reading some infos on some other forums about the Northbridge diode, I read that it went often hot even when the Mac Pro is idling. All the topics I read about it said that it seems to be normal but I wonder why is this diode so hot althought all the other temp sensors are way cooler, as you can see on that screenshot : http://img183.imageshack.us/img183/7736/xrgtempscreenshot.jpg
My Mac Pro is starting up in 32-bit mode because I had too much troubleshootings when trying starting up in 64-bit mode.
Any idea on that issue?
Thanks in advance.

Intel does not 'tell all' about what goes on, and it is a detailed and complex subject on the net.
You can be sure that Hardware Monitor's developer does a fabulous job on the subject of core temperature and sensors.
What was disappointing in the 2009 was it took until December last year for a fix to the audio triggered high core temperature issue.
An 'idle' thread can kick a processor into high gear doing absolutely nothing at all besides 'pestering' it to ask "are you free?" type ping rather than what a Nehalem processor like everyone else wants to do, go into a sleep mode until it needs to be awakened. That robbed processing cycles. iTunes or most any audio app, could instantly kick one or more cores from 35-40 up to 80*C. That is one of side effects of how Intel's HT/Nehalem performs, that temperatures can jump 10*C just opening an app or loading files.
Most PC stability tests run for hours and involve stressing the system but there it is as much to see how far it can be pushed. 85*C can be thought to be break-point or boiling, even though it is still under the 100*C that is commonly thought to be TJ Max (thermal junction).

Mac Pro 2008 8 core 2.8 GHz versus Mac Pro 2009 8 core 2.26 GHz

I'm trying to decide if its worth selling my current MP 2008 with 8 core 2.8GHz 16Gig machine to get
a Mac Pro 2009 with 8 core 2.26 GHz 8 Gig systems. I have a chance to buy a 2009 MP that has 2 years left
on AppleCare but would still need another 8 gigs of RAM. My 2008 MP does what I want as a developer (I don't use it for
graphics) but warranty expires in 7 months. Based on reviews, discussions, etc. They both are about the same in speed but
I like that the 2009 is newer and with more warranty however my 2008 is a real workhorse, has NEVER let me down and
the thought of going to another system and reinstalling everything does not motivate me. As for price, I might get the same
money for my 2008 MP as it would cost me to get the 2009 MP. So the question is, is the 2009 a "better system" to get
or is the 2008 MP more stable? I hear that Hyper-Threading on the Nahelam's are not all that they are craked up to be so if I had
to switch OFF HT then I would actually loose speed on the 2009 even if it uses DD3 RAM a better bus etc..
Your thoughts?
Thanks.

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

Nvidia Quadro 4000 is Freezing / shutting down / Buggy with Mac Pro 2009

I currently have two Nvidia Quadro 4000 mac cards and there causing my Mac Pro 2009 machine to kernel Panic and freeze or shutdown my machine.
I dropped it off at the Apple store for them to diagnose the problem for 9 days and they went ahead and confirmed that it was the card which was causing the problem.
NVIDIA PLEASE UPDATE YOUR DRIVERS FOR THIS CARD FOR MAC.
Its ridicules that if you spend $1200 (apple store) that it will crap out your Mac Pro. I'm waiting for a updated driver in order to test the stability with the Mac Pro
I'm almost 100% sure I did the 10.6.6 update with the stock card, then installed the most updated drivers from Nvidia website and then installed the Cuda Drivers, then finally installing the Video card in the machine. After two days, system was acting up.
Once I get my machine back from Apple tomorrow, I will go ahead and give it one more last try to see if it works. I'm mean the cards are amazing with Adobe Premiere and Media Encoder (super fast), but at the cost that your machine will be very buggy.
Lets wait and see what Apple, Nvidia or PNY will do about the big problem. I'm wanting to keep these babies, so make some moves people and fix the issues for the Professionals.

I hadn't been experiencing the problems you have, but I have been having issues, and yes it absolutely is a case of immature drivers. When the card was released in December, nVidia merely did a simple patch job on the 256.01.00f03 driver that shipped with 10.6.5 rather than include an optimized driver that was comparable to the 259.x driver available on the Windows platform at the time.
Since then, nVidia's engineers have been hard at work doing what appears to be nothing for the Mac. On the Windows side, the Quadro drivers have progressed to 267.11. Rather than provide Apple with updated drivers to include with 10.6.6 or this week's 10.6.7 release, they chose to sit back and wait for the 10.6.7 release and then release their own update.
After 4 months, their best and brightest have brought us <drumroll> driver version 256.01.00f03. To be fair, they changed it from "v5" (the patch job to enable Quadro 4000 compatibility) to "v6". The idea was that it would add compatibility for the Quadro 4000 running under 10.6.7, Sadly for nVidia's Quadro engineers, that driver's installer didn't actually work. It took them nearly a full day to fix that, finally releasing 256.01.00f03v7. As expected, there are no improvements in either performance or stability. In fact, what happened to me is that the new driver actually broke compatibility with Adobe Premiere Pro CS5's Mercury Playback Engine GPU acceleration feature.
Fortunately, I still had my GTX-285 card available, and this evening I pulled the Quadro and re-installed the older GTX card. I really wish nVidia would care enough to release a solid driver update, I really want to like the Quadro 4000. On paper the potential for video production and OpenGL rendering performance should be huge.

Logic Pro 10 requires OSX 10.8.4, which is not officially supported on your Mac Pro (must be Early 2008).
There are, however, unofficial workarounds to install 10.8 on those older models that you can search for on Google.
