Are logic boards interchangeable - such as the 3 early 2005 power mac comp

Hello all,
I have another question similar to the one about whether or not different cases can be interchanged.
My "new" question is this:
Are the 3 "early 2005" Power Mac logic boards interchangeable? In other words, could one use a dual 2.0 or 2.3 or 2.7 ghz logic board in any of these models
or is each logic board specific to the speed of the processor? Or can the quad 4 2.5 ghz logic board be substituted into a dual 2.7 ghz case?
When you answer, could you please try to answer in simple terms.
Thanks,
Stacey Bindman

Hi, sorry for the bump. I am looking to get a new logic board for my G5. I've been looking around eBay and some info you said contradicts the descriptions of some items, namely:
http://cgi.ebay.com/APPLE-POWERMAC-G5-820-1760-A-LOGIC-BOARDW0QQitemZ230384643421QQcmdZViewItemQQptZMotherboards?hash=item35a3fead5d&trksid=p3286.c0.m14
and
http://cgi.ebay.com/Apple-G5-DUAL-2-x-Ghz-Logic-Board-661-3585-820-1592-AW0QQitemZ380161839415QQcmdZViewItemQQptZApple_Desktops?hash=item5883695137&trksid=p3286.c0.m14
The 820-1760-A only has 4 ram slots, and by what Steve said, can only be compatible with the 2.0 ghz processors. The second listing has a model number of 820-1592-A, which the seller claims is compatible with 2.0+ ghz processors.
So which one of you is right? I'm looking to replace my June 2004 board which has the same model number as the second listing, but am not sure if that listing is an Early 2005 model or not...

Hitachi Deskstar 7K1000 (& other 1TB drives) for my Early 2005 Power Mac G5

Hello there:
Like everyone and there grandmother I want a terrabyte drive! But I'm a little concerned.
The Power Mac G5 only supports the first SATA spec (1.5 Gb/s) and all the of the new drives being sold these days are of the SATA II spec (3.0 Gb/s) and use NCQ or TCQ technologies.
I’m really trying to avoid having to install a host bus adapter of any sort to use my new drive(s).
I would like to here from G5 mac users that have installed these drives or other terrabyte drives:
Did you have performance problems, did you have to do “special stuff” to get them to work???
Hitachi Deskstar 7K1000 1TB (HDS721010KLA330) - from what I’ve read this drive does not auto-negotiate to the slower SATA I spec and you have to do something to the firmware in Windows- scarry!
Seagate Barracuda 7200.11 1TB (ST31000340AS)- users of other seagate products have reported a stiff performance penalty when installed in Power Mac G5
And while I’m at I like to here about experiences with the Samsung HD103UJ- I hear lots DOA drives but when these do work their faster that Raptors and that’s super fast!!!
Hopefully my trepidation is unfounded. I just don’t want computer drama... that’s for Windows users ;op
Thanks,
Mike Diaz

Hi-
Welcome to Discussions!
A good place to check on drives, is the Drive Compatibility Data base at Xlr8yourmac.
The Hitachi is reported to be a great drive in the G5, and I have heard/read nothing of this so called "do something to the firmware in Windows" stuff. Mike, the main man at Xlr8 speaks very highly of the Hitachi in his G5.
Another drive that gets great reviews is the Western Digital SE16, and RE2 series. The Green Power also shows to be an excellent drive....
Here's how the "big boys" stack up in a MacPro, tests run by Barefeats, an excellent source on Mac performance related topics. This article tests various drives in the G5.
This article compares the Hitachi, Samsung and WD GP drives.

Why are G5 replacement logic boards in such short supply?

It is now almost 1 week after the service tech I brought my G5 to informed me that my computer needed a new logic board and that Apple had backordered them. He can't tell me if I will be waiting a few weeks, a few months or more.
Is there such a flaw in these logic boards that Apple can't keep them in stock because they are constantly going bad? That G5 is our only computer at home and we use it for both prdfessional and personal purposes.
If anyone has any info, I would like to know how severe a backorder exists on G5 logic boards, just so I have some idea of how long I'll have to wait.

Mark Hannon-
First let me say that you have every right to be upset with the facility that is doing service on your Mac. My experience with "Apple Certified Repair" facilities shows that mileage may vary. Your experience is not necessarily the same as others.
You are making quite the leap of faith about many facts based on this one perceived fact. I am not buying into the idea that you cannot be given an ETA or some other due date regarding your part.
As far as flaws in the boards themselves, I doubt it. There are a bunch out there that are not failing.
Call Apple Customer Relations-1-800-767-2775. Be firm yet polite and have them open up a case number to track your fiasco. Emphasis on the polite. My experience is that once ACR is on it communication improves tremendously.
If this is a machine that you need for business it would be wise to have a backup plan. Just as backup data must be stored off-site in order to ensure continuity should disaster strike, but you must also be prepared to either have a backup machine ready or at least rent one in the interim.

Powe Mac G5 early 2004 gives error (no memory installed) Do I need to replace the Logic Board. Machine powers up,2beeps and power lights blinks 2 times and stops there, No video or any thing?

I just recently aquired a Power Mac G5 early 2004.
When I power the system up. I get 2 beeps
and the small front panel light blinks 2 times continuously.
The error codes show that it means a memory problem or
no memory present. Memory is installed.
In this case do I need to replace the mother board.
The system goes no futher, no video or any thing.

Well, it's possible that someone pulled the original RAM from the computer before they sold it, and repalced it with incompatible RAM. That, believe it of not, would be the best of all world in this case, as a working G5 logic board and its installation could cost as much as a refurbed Intel mac.
I would contact the seller if you did not personally see the computer working before you bought it.
As the computer had to be moved about--possibly shipped--to change hands, first check that all internal cards and RAM Modules are fully seated. They can work loose in some models.

Is replacing the logic board going to make my early 2011 Macbook Pro as good as before

I have an early 2011 15" Macbook Pro that just crashed completely days ago. I sent it to the genius bar and was told that I need to replace the logic board and it costs amost $1000. I'm thinking whether changing the logic board actually means that my macbook would be as good as before. I mean I'm not having high expectations but I hope that it would at least lasts for another few years. I've only had this Mac for three years and I'm not sure if its a consistent problem for the early 2011 models regarding the logic board but I sure had mine replaced for at least three times in the first year when I got it. I'm not sure if I should just use that same money to get a brand new laptop, problem is, I'm quite unwilling to switching to a windows system if you understand how it feels.

The first thing I'd look at is your hard drive ... is your free space 10% to 15% or more of the total capacity? If not, that would account for what you're seeing.

Are MacBook Pro & white MacBook logic boards interchangeable

I have a MacBook pro 13" 2.4GHz 2010 model that needs a new logic board. I'm wondering if they use the same logic board (motherboard) as the polycarbonate MacBook 2.4GHz from 2010 & could I use it in my MBP?
Thanks in advance!
Oh & if anyone knows where to find a source for Mac part numbers for replacement parts it would be REALLY awesome!!

Logic boards interchangeable?

I am an Apple Certified Macintosh Technician, but my company is not an Apple Authorized Service Provider, so I can't get this answer from Apple.
A client has a Mac Mini Early 2006 1.66GHz with a faulty logic board. The repair manual lists a half-dozen board numbers, from 1.5GHz to 2.0GHz. The instructions for replacing the logic board say nothing about differences depending on which board you are replacing. Am I correct in assuming that the boards are interchangeable? The client may decide to pop for a 2.0GHz board for the incremental cost.

all logicboards in the manual Mac Mini Early 2006 will work. (But not the logic boards for more recent mac minis of course)

What logic board is used for the newest 27 inch iMac

If anyone knows that would be awesome!

The one Apple has specially built for those systems. Since the newer iMac's are SEALED system, only RAM can be accessed by the user, not sure why you want to know. It's not like it is some Off the Self motherboard (Apple speak Logic Board) made and available any other place than from an Apple repair center.

Why are there so many problems with the early 2008 Mac Pro ???

Hi everybody out there using Mac Pro's early 2008,
I found out there is a lot of problems with the early 2008 Mac Pro.
My early 2008 Mac Pro has been repaired ones under warranty and now it stopped working again ! Also see under: Mac Pro early 2008 no chime and does not start up. Why is this ????
It worked well for about 2 years and then it just fails and i had this failing issue twice already !!! Is this just a BAD Apple product or how do you think I need to approach this. Let’s face it, these machine don’t come cheap and you at least expect them to work without problems for 4-5 years. What is happening here ???
Cheers, Kavango

go to a black screen after 15 minutes or a couple hours
That is probably an indication that you need to find a new graphics card.
RE: Mac Pro Replacement Graphics cards
1) Apple brand cards,
2) "sold in the Apple store" cards, and
3) "Mac Edition" cards ...
... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
1) Apple brand cards:
• Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5
• Apple-firmware 5870, about US$450
2) "sold in the Apple store" cards
• NVIDIA Quadro 4000, about US$1200
• NVIDIA Quadro 5000, about US$2500
3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:
• SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1
• EVGA GTX 680 Mac Edition, about US$600
The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
If you are Meet ALL of these:
• running 10.8.3 or later AND
• don't care about "no boot screens" etc AND
• can re-wire or otherwise "work out" the power cabling, THEN:
You can use many more cards, even most "PC-only cards"

Logic Boards replaced- for HALF the cost of Apple's service

Instead of paying the $600+ Apple charges for replacing logic boards- take note. I got the following response a few months ago from DWD57 when I figured out my logic board croaked. I sent my iBook in, and they replaced the logic board. It is acting up now, but they have a 6 month warranty, so I'm gonna send it back. At any rate, $350 is better than $600 and it will buy you at least another half a year. They were quite reliable.

It's the logic board.
Don't waste your time with Apple service.
Send it to http://www.dttservice.com/ibookg4.html
They will replace the board for $345 plus 6 months warranty.
Turn around was 1-2 days.
The iBook works fine since they did the repair.

Why are Logic 8 samples separated from the 'legacy' ones? whats the point?

When I installed Logic 8, I noticed that the installer had separated the new (and improved?) Logic 8 EXS24 instruments from the untouched ones (known as Legacy Instruments in Logic). Is it safe to assume that the Logic EXS24 instruments were set up this way because those who bought Logic 8 outright, and not as an upgrade, did not get the Legacy Instruments? If not, why wouldn't they just allocate the Legacy Instruments where they belong within the sample hierarchy? What have you guys done with the Legacy layout? Did you leave it as is, or did you disperse the Legacy Sampler Instruments amongst their 'families' for searching convenience? If I decided to do this myself, do you think there would there be an organization disadvantage when it came time to upgrade Logic 8 to Logic 9? I guess I am just looking for a little background on the reasoning for this, as well as what most other users have done. Thanks!

What is the deal with this new CAF formant anyway? Is it just smaller file size? Are there any downsides to it?
Have any upgrades melded the Legacy in with the Logic 8 instruments for the sake of convenience when searching for instruments? I was thinking I would do that, but than wondered if that would make it extra tedious somehow when the next Logic came out.

I have to get a new logic board, will this effect the memory on my 4s?

My iPhone came back with major problems when I let someone borrow it. I went and had it looked at by a genius at the apple store, and he said the logic board was messed up or something and it was probably put through the washer. I forgot to ask a lot of questions. If I get this 'logicboard' or whatever replaced will my memory on the iPhone still be the same? Like, will all of my contacts and apps be there like before? I had very important documents on there and I had no backup. I also want to know if the apple store can do this for me. Thanks in advance.

Thry will replace, not repair, it.

I got my logic board replaced along with the memory but I just realized I no longer have Microsoft Word. I pair for it and now I no longer have it. What do I do because obviously Apple won't do anything about it.

Macbook Pro mid 2011
Logic Board and Memory replaced in July 2014
Going to type things up for school and just realized that I no longer have Microsoft Word (along with Excel, Powerpoint etc.)
I paid for Microsoft word when I first bought my Mac.

Reinstall it.

Resolution of Logic Board/Airport card failure - iBook G4 2005?

Well, after my first post this morning, I was kindly advised to post a new topic regarding my kernel panics and not-so-nice grey screens of death!
So here goes....
I had experienced this problem since January, when my iBook purchased in April 2006 was coming up to it's first birthday. The problem was this - the iBook would freeze and i'd get a message stating that I needed to re-start. After re-starting, i'd get about 2-3 minutes of use, before the symtoms occured again.
I had the logic-board and airport card replaced twice, by an Apple Store, back in January. The first replacement failed as soon as I got it home, the second replacement failed last night.
So, somewhat dejectedly, I drove to Apple this morning, after booking a Procare session. I was expecting a bill of around £450, as that's what they quoted me back in January, if I had to pay for it. This time I would, as my iBook was 1 month out of warranty, with no Apple Care extended support.
Upon arriving 45 minutes early for my session at the 'Genius Bar', I was promptly served, and advised the tech-guru guy what the issue was. Upon looking at the logs, he checked my warranty, found it had expired, then told me to 'wait', and disappeared into the back office.
Some 5 minutes later, he reappeared, and simply said "have you still got the box for the iBook?"
I did, but it was at home, some 45 minutes away. Then he said these magic words - "We're going to replace it, and give you a new MacBook, free-of-charge"
I was blown away by this approach. I'd expected a repair, possibly a charge, depending on whether they realised that both replacements had been faulty. However, with a machine 1 month out-of-warranty, I did NOT expect a replacement machine.
However, that's what I got. So, I'm composing this thread on a brand-new MacBook Intel Core-2 Duo, with the new spec 1GB RAM and 80GB hard drive.
So, I'd like to take this moment to commend Apple on their outstanding customer-focused approach. Well-done on resolving my issue. Good luck to the rest of you experiencing similar issues.
iBook G4 2005 Mac OS X (10.4.9)

Your ibook G4 (purchased april 06 probably being the 1.3 ghz model) was worth about 440 pounds second hand. The quoted repair bill of 450 was higher than the price of the machine itself, and you were going to pay it?
There are unopened macbooks on ebay for 520-540 pounds (inc apple sales receipts+warranty).
Them asking you for the box means they're going to con another customer into buying your broken machine.
