Will moving a dual 1.25 processor to a single 1.25 motherboard work?

I have a dual 1.25GHz MDD but suddenly it will not start. No lights and no fan at all. It's just dead.
I have replaced the power supply, but that did nothing. I am assuming that the motherboard is dead. I have a single processor 1.25GHz MDD that's working and noticed that the motherboards look identical.
My question is: Can I take the processor from the dual 1.25 and put it on the motherboard of the single processor machine? I guess, my concern is, do both machines use identical motherboards. If so, this should not be a problem, but before I do anything I want to find out for sure.
Thanks for any help you can provide.

I have the same issue, a suspect MDD2003 G4 MB. My wife yanked the ethernet port from the motherboard when she unknowingly tugged at the cable. The part number is 820-1476-A which is the same as the part number I see available for DP 867 units from before 2003 in several eBay auctions. Does anyone know if the 820-1476-A logic board is the 167MHz bus version? I have a secondhand DP 1.25MHz G4 I want to install but I am getting only power light and fan, no drive or chime on boot with my suspect 820-1476-A logic board...

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.

Full backup ( ~ 1 TB ) using external HD - speed USB vs. Firewire vs. eSATA - what are relative speeds - how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)_

    Hi All,
     I'm trying to resume regular scheduled Full backup ( ~ 1 TB ) of drives using external HD (to allow off-site redundant backup storage) .
     What are relative speeds of USB vs. Firewire vs. eSATA ?
     I suspect eSATA connection may be considerably faster … how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)?
      ( The quicker and easier backup protocol is, the more likely one is to use it to backup on a routine repetitive basis.)
Thanks

Adding a USB 3.0+eSATA PCIe card, which The hatter mentions, is the best solution that I've found. See http://eshop.macsales.com/item/CalDigit/FASTA6GU3/. The card is not cheap, but the USB 3.0 works flawlessly (which can't be assumed; ask me how I know) and the eSATA connection allows booting from the connected drive. Grant Bennet-Alder's point about HD speed is important to consider; in addition, the size of the individual files being backed up and where on the backup disk they're going will affect overall transfer speed. For example, using the USB 3.0 connection on that CalDigit card going to a Toshiba 3TB external, the transfer rate for a big file (say a virtual machine file) from an internal SSD boot drive was about 145 MB/sec while a bunch of little files might drop to 30 MB/sec and both rates decrease as an inner partition on the external is used. All told, a nearly 700 GB backup took under 1.5 hours. Using a HD as the source added almost an extra hour, though a WD external was used for that. Using a WD green drive plugged into this http://eshop.macsales.com/item/NewerTech/FWU3ES2HDK/ with an eSATA connection took about 2.5 hours also, but that was bootable whereas the USB 3.0 connection is not.
Another point to consider is that USB 3.0 is ubiquitous on PC's now so there's lots of price competition for externals; not so much for eSATA externals.

PowerMac G5 Image across single, dual, and quad Processor Macs

Good Day,
Our organization is preparing to roll out Tiger. To streamline
this process we have decided to create images for each Mac family in
use. I know I need to find the newest possible model to create the
image but what is the rule for single, dual, and quad processor macs?
Can we use an image created on a quad processor PowerMac on the
dual/single processor PowerMacs?
Thanks

Macs of different models and vintages may take different restore disks. The disk image method of doing this kind of work may or may not work. Use the original disks when faced with different releases or different models. See this article:
http://docs.info.apple.com/article.html?artnum=25784
So a dual-single processor transfer will not necessarily work.
In addition, there are license agreement considerations.
I would not do it unless you know you are in the clear on both accounts.

What is the operating system available for Macbook Dual core Intel processor system

Exactly what model? Do you really mean the old MacBook with the dual core processor or do you mean one using a Core 2 Duo processor?
The last OS X that runs on a dual core Mac would be:
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.

Difference between dual and quad processor

I'm looking into maybe switching from my iMac to the Power Mac G-5 with the 30" screen. Besides internet/email usage I do a lot with PhotoShop CS2. I think at this point in time I don't want to switch to the Intel, and will stay with the standard Mac system. Too many programs to start switching right now.
First, is there a big difference between the dual and quad processor? Since doing Photo Shop is for pleasure and not a business where time is the essence, would I really see a big difference in speed? I would up the 512 memory to probably 2 or 3 GB as well (like I did on my iMac)
2nd, Do I have to add a different graphics card, or can I use the one that comes in the computer? I don't do gaming just still pictures.
Thanks, Allie1254

Allie,
Do get the Quad PPC and the next level up video card and AppleCare.
1: PCI-Express video cards are impossible to come by right now, so get one up from the stock version, you'll come to appreciate it later on. Adds to resale value.
2: ATI who makes video cards for Macs has been bought by AMD, a processor competitor to Intel. Who knows what the future is going to be on that.
3: AppleCare is mandatory, one year isn't enough to cover a investment of this sort unless you do plan to dump it before then. Still AppleCare is a added plus to selling if you do.
If you can get more RAM, more than 3-3.5GB, CS2 will do a amazing 40% more performance because it won't use the slow boot drive as a memory swap (aka "scratch") disk.
If your handy, or have someone nearby that is, you can buy the RAM at Crucial.com a heck of a lot cheaper than Apple.
If you really want more performance, I suggest getting a large stock drive that comes from Apple, and a 150GB 10,000 RPM SATA Western Digital 16MB Raptor and (Disk Utility Erase w/ Zero all new drives 1x first) and then install Tiger on the Raptor with all your space hogging files in new folders on the large stock drive. Keep the boot drive less than 50% filled.
You'll see a incredible snappiness to your OS as Mac OS X "feel" speed is highly dependent upon boot drive speed.
Your Quad's CPU's are powerful and they can crunch quite a bit, like a bulldozer that can move a lot of dirt. So you can do more at once. But large filled slow boot drives and low RAM just hobble them.
If you never cloned your boot drive before, you should learn how to do that too. (Don't clone a different machines OS to a new one though.) You'll need a external firewire 800/400 drive equal to or bigger than your boot drive.

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!

You can check the temps and fans with

or
http://www.kezer.net/thermographx.html
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?

VISTA Support for Multiple Dual Quad Core Processors

Sorry if I missed this in my search.
Does Windows Vista Home Basic support dual quad core processors?
Windows Help & Support:
Under System, you can view the processor type and speed, as well as the number of processors installed, if your computer uses multiple processors.
Yet I see no mention of multiple processors there -- what am I missing?

Hi -g,
all Windows Home versions (XP and Vista) only support one physical prcossor with multiple Cores.
Windows Professional versions (XP Professional and Vista Business+Ultimate) support two physical processor with multiple Cores each.

Can I add a processor to my single 1.8 Ghz, making it a dual?

Can I add a processor to my single 1.8 Ghz, making it a dual? If so, where can I find installation instructions to do that? Thanks.

I've heard from various places that the G5 boards (excluding the 1.8GHz G5, 600MHz FSB) share a common design. However, the SP ones lack a physical socket for the second processor even though the board traces are there. That opens up possibilities if you're adventurous.
I recommend selling your current G5 and using the money towards a dual or quad G5 if you're not too attached to it. It's the simplest solution and would result in a faster system overall.

Can a 2 x 2.66 GHz Dual Core Intel Processor 10.5.8 support an upgrade to Snow Leopard 10.6

I want to up grade to snow leopard so that i can use facetime to talk to my son on his ipod touch.
My G5 computer has 2 x 2.66 GHz Dual Core Intel Processor
I want to upgrade from version 10.5.8. to 10.6 snow leopard
With the processors I have is this possible.

Hi: Your information is somewhat conflicting, (a GS can not have an Intel processor), but if it has an Intel processor, it can be upgraded to Snow Leopard.
Requirements are listed at the Apple support article below.

Does the new iPod touch with iOS5 come with the dual core A5 processor?

If the new iPhone 4s is able to pack a dual core A5 processor into the phone, shouldn't the iPod be able to? I wanna buy a new iPod cause mine crashes a lot but I'm not sure I want another one with just a single core processor...Did Apple announce anything at the keynote about this or something? I didn't watch it through cause it was long so I'm not sure what to expect. Thanks if you can answer it(:

From the information provided by Apple, the only differences between the new iPod Touch and the 4G released last year is the lower price and the addition of a white color.

Satellite P30-145: drive will not recognise dual layer DVDs

I have a Satellite P30-145 with a DVD SupermultiDL drive. When I first got the PC I could write dual layer DVDs without any problems. Now the drive will not recognise dual layer DVDs at all. Even ones from the same box that worked fine previously. I'm using Verbatim Double Layer DVD+R 2.4x discs.
After much searching on the internet I downloaded and ran DVDInfoPro. This application reported that the drive did not support DVD+RW DL. Very strange!!
Can anyone help? The drive is a Mat****a DVD-RAM UJ-831S.

Hi Lan
This drive is definitely DL one but I can just imagine that drive is defective and can not calibrate lens in the right position. This notebook model is more that two years old and if you have used this drive intensively I can really imagine that DL function is defective.
What you can do is to clean the lens and see it this will help.

My HD died on my iMac. I replaced it and lost everything that was on it. I found my source disks from my original purchase for Final Cut Express HD 3.5. I now have Maverick ISO and it will not let me load my software so I can continue my film work. ???

My HD died on my iMac. I replaced it and lost everything that was on it. I found my source disks from my original purchase for Final Cut Express HD 3.5. I now have Maverick ISO and it will not let me load my software so I can continue my film work. How do I get it too recover it without paying for it again since I paid for it already and have projects in progress that need to be completed?

1) Partition your hard drive or add an external drive and install Snow Leopard (with the Optional Rosetta) into it and then you can dual-boot (System Preferences:Startup Disk) into Snow Leopard and run FCE 3.5 there.
2) Use one of the following methods to install FCE 3.5 into Mavericks:
a) Pacifist: http://www.charlessoft.com/
b) Jeremy Johnstone's Terminal method: http://www.jeremyjohnstone.com/blog/2012-03-11-installing-final-cut-pro-studio-2 -0-on-mac-os-x-10-7-lion.html
Reports on this forum seem to confirm that Final Cut Studio 2 will continue to operate in Mavericks once it is functionally installed, albeit some plug-ins may fail to function. FCE 3.5 is the same generation as FCS2, and presumably will continue to operate in Mavericks, as well.

I tried updating my iPod, and ever since it has not worked at all. If I hold in the lock & home button, it will tell me to plug it into iTunes. Once I do that, it says it will restore but every time, restoring it fails. My iPod is not working at all, and I really have no idea what to do. It is just a black screen, and occasionally the white apple will appear as if it were turning on, but it won't turn on. I just need some suggestions on what to do!

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have recently purchased an IPad Air. This comes with "IPhoto" as well as it's usual photo App. I do not have a Mac, instead I am syncing it to my windows PC. Is there any way of actually moving a picture around, (arranging photos in a single album), in either of these apps???? They claim to be able to "Organize" or "arrange" Photos, but for the life of me I can't figure out how......could you recommend any apps that actually allow someone to move individual photos around on an IOS Device.

No, reordering within folders and albums is not supported. the yare arranged automatically by date. I found this, but I have not used any of the apps besides iPhone. You might check the descriptions to see if they do what you need.
