Mac pro quad core overheats since installing snow leopard OS

I seem to have a lot of overheating since installing on my pro tower. the fan runs constantly. additionally, the monitors go to sleep on their own and I can't wake them back up. does LION OS fix this or am I doomed?

Bad or faulty RAM
Poor power cable connection to the back or to the outlet
Running off a UPS that is too small (you want 900W / 1350VA range)
Of course disconnect all peripherals but mouse/kb and try in Safe Mode.
Reset SMC www.apple.com/support/macpro
Run Apple Hardware Test
I wouldn't rule out it being the ATI 5770 either.
I know there are other threads w/ identical symptoms.

Windows – but Which? (What to install on Mac Pro Quad Core?)

First, apologies in advance if this seems like repetition of a recent topic, but I read through the recent "Vista vs XP" thread and it didn't quite answer my questions.
Basically, I'm planning on buying a Mac Pro "Quad Core" 2.8 and installing Boot Camp and a Windows OS startup. This puts me into the notoriously tricky area of picking the right version of Windows for my needs, something I haven't really had to deal with in regards to OS X.
Basically, I'm not looking for something with too many bells and whistles or to much bloatware built into the OS. Also, I'll probably be using some older software/shareware, so backwards compatibility is an issue. On the other hand, I'd like something that works with the Quad Core architecture at its greatest efficiency.
This means I'm wondering about a couple of features that I may or may not need, and it would be of great help if you folks could point me in the right direction regarding these:
x64 – Since the Xeon processors in the Mac Pro are 64-bit processors, am I better off with "x64"-compatible versions of Windows (either Windows Vista or x64 versions of XP)? Will this cause problems starting up older programs that may not have been written for x64?
*Dual Processor Support* – the Quad Core, of course, is a dual processor – will I get better performance from a version of Windows that list "Dual Processor Support" among its features (basically, the "pro", "business", or "ultimate" versions of XP and Vista)?
If I need those features, I'm probably looking at getting either the x64 version of Windows XP Pro or the Business or Ultimate versions of Vista. However, I'm leaning against Vista based on backwards-compatibility and bloatware issues. That leaves XP Pro x64, but I might go for a more basic version of XP if I find out the x64 or DPS features aren't actually something I need. (The other "extras" in XP Pro don't sound like anything I need.)
Also, I'm likely to install Parallel Desktop at some point and don't want a version of Windows that would have compatibility problems there, either.
Anyway, any answers you folks can provide for me in this regard would be very helpful.
Thanks in advance,
Peter

Truth is, I am disappointed in VMware Fusions slow walk toward full support for 64-bit and SP1 but 2.0 beta is getting there. Never used Parallels but best to check their own support forums. They also updated the 1.x version recently.

You don't need anything first, except I would start with a new hard drive for Vista, don't even do anything with it and pull OS X drive, boot Vista DVD and go from there, just as you would normally. Much easier. After it is installed is when you need Apple BootCamp from your Leopard OEM DVD, install, and then Apple Software Update will take care of 2.1. And install your graphic drivers yourself.
The problem(s) come with trying to use BootCamp Assist and setting up partitioning, and it only makes it harder - not easier - on Mac Pro (you aren't and don't want to use your OS X boot drive).

And their Mac Pro area http://forums.macrumors.com which has a lot of Vista talk from Mac Pro owners.
The only real issues are which graphics card to get today or in next weeks, what drives you are going with and other upgrades like memory (8 x 1GB is actually a good base ideal figure so all DIMM slots are taken up).
Barefeats has a number of benchmark articles:

WD 300GB Raptor: http://www.barefeats.com/hard103.html
- this is the drive to die for, but not natively supported
I buy most of the upgrades I need over the last ten years from OWC http://www.MacSales.com that specializes in Mac.

- until the WD "Black" series (I guess Blackbird name or SR71 are already taken) along with 3rd generation of their RE series drives. WD has been popular, reliable, with Mac Pro for last two years. Can't say the same of every vendor. Samsung F1 is also a real winner.
If you buy only one book to understand and get the most out of OS X: "Mac OS X: The Missing Manual" (Pogue has a Missing Manual Series on most everything, and this is the most popular recommended for Mac OS).
http://books.slashdot.org/books/08/02/27/1551206.shtml
I needed 3-4 for Vista before I found "Administrator's Pocket Consultant" and O'Reilly's "Vista Annoyances" are both excellent along with MS Press's "Inside Out."

UPGRADING AND MIXING MEMORY ON MY MAC PRO QUAD CORE DUAL 2.8 (Xeon)?

Hello,
I have a Mac Pro Quad Core Dual 2.8GHz (Xeons) with 4GB of memory (2 x 1GB Apple modules + 2 x 1GB other brand - Shown as "Manufacturer 0x855D") and now I want to fill the other 4 memory slots by adding an additional 16GB (4 x 4GB modules) for a total of 20GB of RAM.
My 2 questions are:
1.- In which order/pattern should I install these new 4 X 4GB modules along with my original Apple 2 x 1GB modules and the "Manufacturer 0x855D" 2 x 1GB modules the best way (for better performance)? - I have heard stories that if I do it improperly, I could slow down my Mac Pro...
This is how I have them configured right now:
Raiser A / DIMM 1 = 1GB (Manufaturer "0x830B") - I assume this is the Apple memory, right?
Raiser A / DIMM 2 = 1GB (Manufaturer "0x830B")
Raiser A / DIMM 3 = Empty
Raiser A / DIMM 4 = Empty
Raiser B / DIMM 1 = 1GB (Manufacturer "0x855D") - How can I find which manufacturer is this?
Raiser B / DIMM 2 = 1GB (Manufacturer "0x855D")
Raiser B / DIMM 3 = Empty
Raiser B / DIMM 4 = Empty
2.- What brand would be most compatible to work with my Apple 2GB (2 x 1GB) factory memory? Kingston? Crucial? Mushkin? iRam? Corsair? OWC? (Does OWC sell their own brand? or which one do they carry?-its not specified on their web)
Thank you so much in advance for all your help!

Error message on my Mac Pro Quad Core Dual

Hello..I'm hoping someone out there can help or advise me.
I turned on my mac this morning to find it's normal loading screen of grey with the darker grey logo in centre..all normal at this stage. This was followed by a wipe from top to bottom making the background grey a little darker and in the centre the apple logo was replaced by what appeared to be a semi transparent power button symbol with the words. "You need to restart your computer. Hold down the Power button for several seconds or press the restart button"
I have tried this several times to no avail I have also zapped the P RAM again nothing. Can anyone out there help. I have a Mac Pro Quad Core Dual which is only a few months old and is up to date with its system software.
I could be so grateful of any assistance.
Warm regards
Sophia

Make an appointment. But in the meantime...
So from cold boot, you can't do the Command Option P R through 2-3 full reboot cycles (don't let up)?
Unplug everything and let it sit overnight without power cord or anything. That is the only way to rest the SMC system management controller on the 2008 model, the older model still had a reset button.
Also learned that the 2008 Macs can all boot AHT if the original OEM installer was used to install the system and the drive has not be completely reformatted and retail OS X used, just holding down "D" on startup. But you have to
Also, pull all your hard drives. Rule out that, which I have seen a hard drive cause panic on startup, which required disabling journaling and other repairs from Disk Utility and deleting caches, then repair, and finally do Safe Boot (shift key down on startup).
The only way to test RAM is with TechTool Deluxe or Pro; with Memtest or Rember; and to test some devices is to try using a differnent one, keyboard and mouse included if you have any.
Last hope: open case, look inside, take the two RAM Riser cards and pull out, check the DIMMs are fully seated.
If you have 3rd party memory, remove that (would need to before taking in probably).
Might want to put RAM back to way it shipped with 2 x 1GB and one DIMM on each Riser in slot one. Maybe that will wake this sleeping giant. Changing RAM config use to be one way to clear nvram in the distant past in the time of Arthur.
PS: it is "odd" to find a BTO 3.2GHz system, and only 2GB. For memory performance, Barefeats found a marked improvement with 8 DIMMs, and of course Mac Pro really needs memory to feed 8 cores and pro apps (2GB would be okay for web and email type use only).

Are these Seagate 2TB drives compatible in my Mac Pro Quad Core 2.66 GHz?

I still have an Apple Mac Pro "Quad Core" 2.66 that was introduced August 7, 2006. I currently have 4 of the following Seagate internal hard drives installed: ST3750640AS SEAGATE BARRACUDA 7200.10 - HARD DRIVE - 750 GB - INTERNAL - 3.5" - SATA-300 - 7200 RPM - BUFFER: 16 MB
I want to know if these hard drives will work in this computer: Seagate Barracuda XT ST32000641AS 2TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive.This computer is powered by two 2.66 GHz dual core Intel Xeon 5150 processors.
The old drives were purchased from NewEgg and I want to purchase the new ones from there also. Are these 2TB drives compatible in my computer?
Thanks,
Lou Hosta

SATA is SATA.
Apple introduced GPT (GUID) years ago to support 2TB and larger (default partition scheme).
SATA III is also backward compatible with SATA II (otherwise, who would Seagate have to sell to?)
The only issues have been with green drives, using green version for RAID or for performance purposes.

Mac Pro Quad core Intel Xeon upgrade advice please!

Hi all, i have a Mac Pro Quad core 2 x 2.8ghz Intel Xeon (2008 model) with 4gb RAM.
I am planning on giving it some upgrades and a fresh OS install as it is slowly grinding to a halt (particualrly noisey hard drives)
Can anyone recommend best/fastest/silent! S-ATA hard drive to upgrade to?
Can anyone recommend a good replacement ATAPI DL DVD-RW Drive as mine is also on its way out.
Ram upgrade. Lots of space for RAM so what would you all recommend?
Ultimately i am finding myself working with alot of large PS file and so would welcome any suggestions to improve/soup-up the processor/performance.
Thanks for any advice in advance...

24GB RAM gets cost ly when you look at 800MHz FBDIMMs in 2x4GB
You shoudl have added more as 4GB is vary basic and miinimal
Any SATA drive device is fine. WD Black 1-2-4TB / WD 10K VRs are fast but not as quiet though I do hear those WD Blacks.
A single SSD for a system is nice.
10.6.8 works best in that system.
Your GPU most probably is in need of an upgrade.
You should never need to do a reinstall of the OS. Clone. Yes. And start wit h a new OS by not upgrade in place over the old OS but that is when to clean install, clone and use Set up Assis tant.

IMac 27" or Mac Pro Quad-Core?

Hello all,
I understand that this topic has been covered before although I am still unsure and I am looking for some help please!
I am currently looking into purchasing a new computer to complete my architectural post-graduate degree. I currently use a PC, which I have done so for many years and initially I was thinking about buying a customisable Dell XPS sticking to using PC’s. Having recently been sent an email from Apple regarding student discounts offered on the Mac range I thought I'd look into getting an Apple having heard nothing but praise and also that it can also run Windows XP (via ‘Bootcamp’). This would mean I would effectively get 2 “computers” for the price of one, however, after hours of research, scrolling through web pages I am torn between the Mac Pro Quad-Core and the iMac 27” (Intel i7) !
I mainly use Microstation V8/AutoCAD, Maxwell Render, Adobe Photoshop/Illustrator/InDesign, SketchUp, etc, and require a computer which can run programs quickly and efficiently, including some rendering. I will be switching between both operating systems, but will heavily use Windows to run most of my software.
I was first hooked onto the iMac due to its sheer simplicity, elegance and also the specification (Intel i7) which was on par with the Dell I was considering. Although reading deeper on various forums, articles, I found that the Mac Pro Quad-Core might be a better alternative for future proofing (IE. Upgradable hardware) but it costs a little bit more than the iMac plus no monitor included. I feel that the iMac will suffice for what I need but I am not sure how about its longevity. I will be using the computer intensely for the next year, however, after I graduate I will see the computer being used casually.
Another question is, if I were to use Bootcamp how would I share drivers (printers and scanners) between both Windows & Mac OSX? Also, when running Windows OS, would I need to install anti-virus software just like a PC?
I am wondering if anybody could shed some light, assistance, experience and guidance to help me with my purchase please.
Many thanks in advance!

I would say a lot of it depends on just how extensively you expect to be using it after you graduate. Either system should carry you through a single year easily, but the Mac Pro obviously has the expandability advantage that will help extend the tail of its useful life.
IMO, a reasonable expectation for an iMac is 2-3 years, while a Mac Pro is 3-4 for the quad core, 4-5 for the 2x4-core, and if you're buying one of those 12-core systems, odds are you're doing some serious number crunching and you'll be replacing the thing pretty quickly.
So, if you think there's a better than 50% chance of needing to keep this computer for a longer than 2-3 years, go for the Mac Pro, otherwise you can get the iMac now and see where life has taken you in 2-3 years.
As for bootcamp... Think of it like dual booting on a PC. Bootcamp does NOT allow you to run both operating systems at the same time, it's one or the other. Think of it like a time share. Programs like VMWare and Parallels let you run Windows in a virtual machine, but odds are you won't want the performance hit the emulation brings with it. So, there's no need to share drivers, because you'll need to install drivers for all hardware on both operating systems. You'll just need to make sure that any hardware you buy will work with both Mac OS X and Windows. When you're running Windows, it's no different from as if you had bought the Dell you were contemplating. Everything you would have done on the Dell as far as security software, you should do on the Mac with bootcamp. Mac OS X doesn't necessarily need AV software (yet), but Windows absolutely does.

Adding new hard drive to Mac Pro (quad core)

I've just ordered a new Mac Pro quad core (2.66 GHz) with one GB HD. Since Apple is charging £240 for a second drive I decided to get it from somewhere else. I found a 1GB Western Digital Caviar Green but I also noticed 1GB WD Caviar Black. I wonder if anybody has any experience of those drives and would they work with the latest Mac Pro ?
Does anybody knows what make of drive is Apple using in their latest Mac Pros ?

Welcome to Apple Discussions!
Do you keep your data backed up?
If not, you should always do so*:
http://www.macmaps.com/backup.html
You never know when a hard drive or a directory might go bad. Having a bootable clone is a must.
That link also shows you some tools you can use to recover data.
If you aren't backed up, try buying those tools first, before attempting to repair the directory.
Directory issues can be fixed with these tools*:

Welcome to Apple Support Communities
Time Machine should be enough to make a backup of your files. Also, it should back up all folders, so open System Preferences > Time Machine > Options, and make sure that there are no folders included in the excluded items list.
If you want to create a bootable clone of your hard drive, you need to use an app like Carbon Copy Cloner or the Disk Utility's Restore feature > http://pondini.org/OSX/DU7.html

Fileshare between my Mac Pro Quad Core Intel Xeon (64-bit) & Power Mac 9600

I want to make my Power Macintosh 9600/233 (Mac OS 9) a shared computer with my Mac Pro Quad Core Intel Xeon (64-bit)(Mac OS 10.6.6). I am using a Netopia Model 3346N-VGx DSL Ethernet Managed Switch to network with my Samsung printer and the Mac Book Pro.
I also have a Power PC G4 (Mac OS 10.5.8) connected (via a Ziplinq 48" Retractable Crossover Network Cable) to a Farallon EtherWave 10 Base-T AAUI Transceiver, which in turn is connected to the Netopia, from which I can share files. All of this is ethernet connectivity.
I thought I could connect my 9600 using the same method as for the G4 or by connecting the ethernet cable from the 9600 directly into the Mac Pro Quad Core. However, neither of these methods work.
An additional stumbling block is that I have not used this 9600 for several years and am not sure of its account name. I'm fairly certain of its password. But because I don't have a second monitor for this machine, I can't muddle my way in.
My questions:
1. What might be a network solution to this dilemma?
2. Or, do I need to get another monitor for this computer and leave it un-networked and just transfer files manually?
3. Or, would whatever hard drives are in the 9600 be transferable into the networked G4 or the main Mac Pro? (not sure what they are.)
Any suggestions greatly appreciated.

Oh man, what a dilemma...
1. What might be a network solution to this dilemma?
Without a monitor on the 9600, almost none. At the very least you'll need to configure the server with appropriate network settings for your environment, and that can't be done headless.
You might only need a display for long enough to setup the network, but you'll need one all the same.
Once the network is configured your options are either AFP or FTP, but I'm not even sure the old version of AFP is supported anymore, which means you may need to fire up an FTP client on the 9600 and push the files to your MacPro.
2. Or, do I need to get another monitor for this computer and leave it un-networked and just transfer files manually?
As mentioned above, you're going to need a monitor at the very least to configure the network settings. I'd be inclined to say at that point you might as well copy the files off any way you can and put the 9600 to rest. If you're really, really fortunate and the 9600 has a CD burner I'd probably use that and count myself lucky
3. Or, would whatever hard drives are in the 9600 be transferable into the networked G4 or the main Mac Pro? (not sure what they are.)
The 9600 shipped with SCSI drives, which no current Mac support (at least without a SCSI card), so there's no way to remove the drive from the 9600 and attach it directly to the MacPro.

Since installing Snow Leopard and Lion two weeks ago, my iTunes program opens seemingly at will. It usually starts playing music, too. What is causing this?

Since installing Snow Leopard and then Lion on my Intel-based iMac two weeks ago, my iTunes program seems to open at will whenever the computer is on. It often begins playing music, as well. What is causing this and how do I make it stop?

There are ways to minimize, mitigate, and help avoid a lot of problems.
Bootable backups.
Zeroing a drive twice before using, and format it with SL DVD Apple Disk Utility for sure.
Even a clean install should import old apps without having to reauthorize.
If you must do an upgrade, do it from the SL DVD, after repairing the drive and be sure to use the SL version of Alsoft Disk Warrior (4.2).
Wait six months before jumping on a new OS.
10% is still too many. Yes, it is more sensitive to RAM and hard drive errors, doesn't like some controllers; most ext hdd cases; and enough software to make for test-only status. And it only IDs some known incompatible applications, drivers, extensions, etc and does not remove even those always in best manner.
Plus, there are problems with the new Rosetta and the cache files it now uses. So some apps and plug-ins will cause more trouble. Not all are ready. Good reason to hold off for the months it takes.
Other devices act different as far as on/off behavior.
(Migrating from G5s to Mac Pro can cause all kinds of problems, weird behavior, sluggish system, and why anyone that went down that road was strongly recommended to NOT use Migration Assistant for any of their applications, and to ONLY do clean/fresh installs of any apps. If you skipped that day, didn't read the Guide to M.A., or didn't want to do fresh installs then, your system could have been on borrowed time. If you did do clean install of applications, great.
Installing SL can result in a corrupt directory - I think and it "seems" to be happening, but no real proof, just gut feeling and instinct (underlying file system problem? weak sectors that pre-existed waiting to happen?).
Remember all the "there just aren't a lot of 64-bit drivers" for Vista and XP? it's come home to roost.
... my guess is not enough incense and offerings. To hop into TimeMachine and SuperDuper backup images and pull the 1TB for another day (week, month, year).

Quicktime player problems since installing Snow Leopard

Since installing Snow Leopard my Quicktime plays weird. The are sharp horizontal streaks and glitches where the picture smears (the only way I can describe it). If I restart or shut down and restart, that sometimes resolves the problem, but for only a short while.
Any suggestions from any of you pro guys out there?

Hi:
I'm not a pro, but I think I would download the OS X 10.6.4 combo updater and apply it. Something may have gone wrong with the initial update. Alternatively, I would reinstall OS X 10.6 from the software install DVD and then run software update.
