G5 with intel dual quad core 3.0Ghz Crashing

ok I have tried everything i know no this G5 tower and it keeps crashing i can use it fine for a while then all at once blue and red lines come up on the screen and the computer locks up and then the black box of death as I have come to call it pops up and tells me to restart the computer it just started this about 3 days ago. there was a power outage and after that it has been acting up the UPS i had it hooked up to went dead. anyone got any ideas what could be causing this?

Is the tower portion (bottom aluminum metal case) kept in an enclosed area like under a desk? Is there plenty of room and ventilation where the machine is kept?
You might be experiencing thermal shutdowns. If enough thermal shutdowns occur, hardware damage may be the result. The Achilles heal of the MacPro is potential high temperatures in and around the video card area where it connects to the logic board. This also may be causing the weird lines and graphics.
You can run a shareware program called Hardware Monitor (you can find it at versiontracker dot com) to check the operating temperature of your machine. The software also has specified limits displayed to let you know if the temperature is too high for your specific machine.
There have been several MacPros that I've worked on that had this problem. It turned out to be that the excessive heat damaged both the logic board and video card and both had to be replaced. Do you still have Apple care for this machine? If not, I know of some good 'organ donor banks' if it turns out to be hardware failure.
Keep us posted,
Mike

Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows

I've got a Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows. I've tried all of the following initial tests as suggested on forums:
-Ram swaps
-Alternating video card in PCIe slots
-Trying alternate video card
-resetting pram and smc
-Multiple tests with memtest86+ over 26hrs and no failed ram
-Multiple tests (8-12 cycles) with apple HW diagnostics and no problems
-Firmware is approved firmware for early 2008 model...no new updates.
Gentoo livecd works fine and I even installed to hard drive and it boots fine with it. In addition to above tests I also ran a linux stress test putting all 8 cores at a load of 22 for 2.5hrs with no problems.
Memtest86+ for 24hrs+ yields no problems.
Where problems occur:
Booting off hard drive, DVD or firewire yields an immediate curtain of death and booting off a new snow leopard DVD dies about 25% into the install.
Looking at error log and a quick dmesg shows "Package 0 didn't get an HPET" and complains about AppleIntelCPUPowerManagement.kext. Google turns up illegal uses of this, so doesn't apply to my use case.
I'm a bit stumped since all was working well until one day it was non-stop curtains of death and can't get them to go away.
A logic board replacement at $1100 is not a feasible option for something that works on linux and windows, but not OS/X, is a bit disappointing and somewhat surprising.
Thanks for your help and advice.
Regards,
Marcos

Someone here once thought they knew EFI and Open Firmware a little, and used some commands from OF library that an Intel EFI Apple system didn't like. New logicboard.
Of course to run or boot OS X and see video you need EFI based card. The presence of some PC cards can block OS X from booting.
The fact you get part way through SL DVD, pull all the drives, put in a new drive and format it from SL DVD.
Most of the things you tried are what are more common with PC hardware. Including where people have tried and failed to install OS X on unsupported hardware.
I suppose it is possible something tried and failed to modify the Mac's firmware.
If you have Windows running, and you have WD drives, WD just posted new Lifeguard utility which is what I use to do a good job of stripping a drive down and recertify it for reuse, works wonders. Maybe same for other makes with vendor utility.

Why is it that the new macbook pro processor upgrade option only offers up to 2.8 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz Intel Dual Core i7 Macbook, is the new one tuned to go much faster anyway?

Why is it that the new Macbook Pro processor upgrade option only offers up to 2.8 Ghz boosting to 3.3 Ghz with Intel Dual Core i7, when back in Sep 12 I bought a 2.9 Ghz boosting to 3.6 Ghz Intel Dual Core i7 Macbook, is the new one tuned somehow to go much faster anyway, or will the new one be slower in fact? Or does the solid state drive compensate for the lack of increased processor capacity?

The CPU's come from different Intel 'families'. The older ones are 'Ivy Bridge' and the newer ones are 'Haswell'. Numbers alone will not determine the efficiency of CPU.

Can I install Windows 7 64-bit on my mid-2007 dual quad core "Clovertown"?

Hi all,
I want dearly to install Windows 7 64-bit on my MacPro, but the only online compatibility information says bootcamp 3.1 for 64-bit works with "early 2008" Macs and not "mid-2006" Macs. I'm stuck in between, for I purchased a mid-2007 MacPro with dual quad core Clovertown processors, which are 64-bit. I'm unsure though if I will run into problems trying to use Bootcamp 3.1 in this case (I have Snow Leopard as well). I've called Apple support several times and they basically say they are not sure, but don't see why it wouldn't work. Any thoughts from the group?
Cheers,
Ben

ATSServer CPU @ 200% LOCKS-UP Mac Pro dual quad-core desktop

My dual quad core running Mac OS X 10.5.5 locks-up frequently at boot.
Required hard (destructive) reboot, until I figured out workaround
described below. Apple really needs to fix this as a high priority.
Symptom: Desktop freezes and the system becomes unusable.
Usually occurs when booting the system, but can happen
at other times spontaneously.
When it occurs during boot (after desktop first appears, usually
as task bar is starting to populate), the wedging is so bad that
applications are effectively 'suspended' mid-launch.
Icons and menu and mouse buttons and keyboard completely unresponsive.
Usually just a spinning beach ball that tracks with the mouse is present.
Attempts to resolve (both failed):
1. Did a fresh install of Mac OS X (with data transfer) and upgraded,
which brought system to 10.5.5. (Problem appeared immediately
on fresh installed system).
2. Totally re-indexed Spotlight and de-selected option to not index
PDF documents.
Workaround:
1. Enable 'ssh' logins and root user.
2. Login via 'ssh' from remote system, while Mac Pro desktop frozen.
3. Become super user in 'ssh' session.
4. Find ATSServer with 'ps -ef' or 'top' command.
5. Terminate ATSServer with 'kill -9'
6. Desktop on Mac Pro immediately unwedges and applications
that hung during start-up finish launching.
/var/log/system.log (many messages like this):
System/Library/Frameworks/ApplicationServices.framework/Frameworks/ATS.framework /Support/ATSServer[241]: FOExceptionMainHandler caught a fatal exception at 0x96028036
Safari[151]: GCGetStrikeMetrics failed: error 5.
Plea from customer:
Apple: PLEASE post an update to fix this very soon.
If anyone has clear instructions on what I can do to fix properly until
Apple comes up with a real fix, for example, caches to clear,
how to identify a faulty file, or quarantine a faulty faunt,
or any other diagnostics, please feel free to reply.
My machine was already in the shop for five weeks recently for repair,
and I can't afford down time, because I'm mid-project right now,
and it will be a HUGE setback to have to bring my machine into the
shop again for another 'n' days.

I'm also seeing this problem on my MacBook with 10.5.5. After killing ATSServer via ssh, I looked in the Console, and found these console messages which occurred when the GUI locked up:
10/18/08 12:44:03 PM com.apple.ATSServer[2554] Notice ATSServer(2554,0xa076afa0) malloc: * error for object 0x83ac00: incorrect checksum for freed object - object was probably modified after being freed.
10/18/08 12:44:03 PM com.apple.ATSServer[2554] Notice * set a breakpoint in mallocerrorbreak to debug
The problem seems to happen whenever I mount a certain remote shared volume (AppleShare) from my old desktop computer (G4 Dual 450 running 10.4.11). I guess it could be that ATSServer is choking when trying to generate QuickLook previews for some document on the shared volume...

I have a late 2012 mac mini with an i5 2 core can I replace it with an i7 quad core?

A few places online may still offer the i7 2.3GHz quad-core Late 2012 MINI (Oct 2012 to Oct 2014)
that allows the user-upgrade of RAM to 16GB, and this one I've seen is a Server model and has
two 1-TB Hard Disk Drives. The B&H store in NY online has this listed, if in stock now, price &
shipping in continental US is good until tomorrow.
Your i5 dual-core is still desirable to many, & you may be able to resell it if not needed.
Good luck & happy computing!

XServe dual quad core max power consumption

What can I expect to be the max power consumption of a dual quad-core XServe?
I have four new XServes that I administer in four separate locations and I need to know what Apple recommends for an Uninterrupted Power Supply (UPS) per server.
Right now, I have a 500VA one that I've had on hand at least one site. However, I've noticed that this one, eventhough the UPS has a new battery in it, does not support an XServe -- ie, when I test it, the XServe shuts down abruptly. My guess is that 500VA is inadequate.

What Apple might recommend and what might work in your environment, I do not know.
The APC SmartUPS 1500 works reasonably well for an Xserve and its usual accretion of giblets and accouterments, and Mac OS X Server automatically recognizes this device via its USB connection.
And one thing I've discovered that's not widely listed. Get yourself some short power cords. A handful of appropriately-rated power extension cords (of about one foot in length) makes most UPS products far easier to deal with. These cords are a few dollars each from various vendors, and very useful.

Hi there,
If you purchased FaceTime from the Mac App Store, the first thing that I would recommend is removing and reinstalling the application. Take a look at the articles below for more information.

DSC 8.6.1 wrong timestamps for logged data with Intel dual core

Problem Description :
Our LV/DCS 8.6.1 application uses shared variables to log data to Citadel. It is running on many similar computers at many companies just fine, but on one particular Intel Dual Core computer, the data in the Citadel db has strange shifting timestamps. Changing bios to startup using single cpu fixes the problem. Could possibly set only certain NI process(es) to single-cpu instead (but which?). The old DSCEngine.exe in LV/DSC 7 had to be run single-cpu... hadn't these kind of issues been fixed by LV 8.6.1 yet?? What about LV 2009, anybody know?? Or is it a problem in the OS or hardware, below the NI line??
This seems similar to an old issue with time synch server problems for AMD processors (Knowledge Base Document ID 4BFBEIQA):
http://digital.ni.com/public.nsf/allkb/1EFFBED34FFE66C2862573D30073C329
Computer info:
- Dell desktop
- Win XP Pro sp3
- 2 G RAM
- 1.58 GHz Core 2 Duo
- LV/DSC 8.6.1 (Pro dev)
- DAQmx, standard instrument control device drivers, serial i/o
(Nothing else installed; OS and LV/DSC were re-installed to try to fix the problem, no luck)
Details:
A test logged data at 1 Hz, with these results: for 10-30 seconds or so, the timestamps were correct. Then, the timestamps were compressed/shifted, with multiple points each second. At perfectly regular 1-minute intervals, the timestamps would be correct again. This pattern repeats, and when the data is graphed, it looks like regular 1-sec interval points, then more dense points, then no points until the next minute (not ON the minute, e.g.12:35:00, but after a minute, e.g.12:35:24, 12:36:24, 12:37:24...). Occasionally (but rarely), restarting the PC would produce accurate timestamps for several minutes running, but then the pattern would reappear in the middle of logging, no changes made.
Test info:
- shared variable configured with logging enabled
- data changing by much more than the deadband
- new value written by Datasocket Write at a steady 1 Hz
- historic data retrieved by Read Traces
- Distributed System Manager shows correct and changing values continuously as they are written

Meg K. B. ,
It sounds like you are experiencing Time Stamp Counter (TSC) Drift as mentioned in the KB's for the AMD Multi-Core processors. However, according to this wikipedia article on TSC's, the Intel Core 2 Duo's "time-stamp counter increments at a constant rate.......Constant TSC behavior ensures that the duration of each clock tick is
uniform and supports the use of the TSC as a wall clock timer even if
the processor core changes frequency." This seems to suggest that it would be not be the case that you are seeing the issue mentioned in the KBs.
Can you provide the exact modle of the Core 2 Duo processor that you are using?

Linux Enterprise V5 on Intel i7 Quad core..

Has anyone tried installing Oracle's Enterprise Linux and Oracle VM on an Intel i7-920 Quad Core CPU?
How about Oracle 10g, 11g on the same CPU?
I'd greatly appreciate if you can share your experiences with me (and others).
Your feedback is greatly appreciated.

Hi Paul,
Just curious, what processor did you use?
You are right, I was not referring to production installation, however, there are a lot of production installations that have been virtualized. So it is quite ok to virtualize production databases/servers etc...
I think with Oracle buying Sun, you will see more of that. Sun has an excellent product called XVm-VirtualBox. I took that and installed Ubuntu and Solaris for Intel. Works flawlessly. Next step is to install Oracle 10g or 11g in it.
Thanks for your response.
