Can a 167mhz bus logic board is kill a 133mhz bus cpu?

Well, I'm trying to upgrade my g4 MDD dual 867mhz... So i found a logic board from a newer mdd with 167mhz bus. So anyway, to test the board (got off ebay) I put the dual 867mhz cpu and the ram..ect.. try to boot it up and I got a black screen fans running crazy?? I turned if off.. Put every think back to stock with the old logic board and it doest the same thing. the computer worked great befor for this... Did i kill the cpu in the high bus board? I tryed every the resetting the PRAM, reseating the cpu.. Its just dead! thanks for any help

The CPUs would get very hot very quickly & could be damaged because if you didn't change the Resitors that set the CPU multipliers, it would try to run the 867s at 1.08GHz.
A 25% overclock on the 867s would be a strech in my experience.

Where can I find a logic board for iMac G5 17" (EMC No. 1989) Apple Part

HI Where can I find a logic board for iMac G5 17" (EMC No. 1989) Apple Part #: 661-3290, 661-3351?

Thanks--makes life easier!
I found DV Warehouse has a number of G5 logic boards but none had the exact model number:
http://www.dvwarehouse.com/iMac-G5-Logic-Board-c-4771.html&pltid=05fedd9f246e2a1 dbc9f35cd6712e781
They have a toll-free number. You could ask if another board # would be compatible.
Another option is to contact recylers or schools shucking off older gear. Using the enigma of " A used computer is worth more parted out," you might be able to pick up another G5 cheaper than its LB. Unless the LB had the dreaded "leaky capacitor" failure, most computers don't get discarded for a bad LB.

Where can I purchase a Logic Board for a 24" Apple Cinema Display?

My 24" Cinema Display started to flicker and black out shortly after I purchased my most recent MacBook Pro. Apple felt that the issue was the MacBook Pro so they replaced it. The problem continued so they suggested I take the Cinema Display to the Genius Bar. The display was out of warranty and the Apple Genius felt the issue was a bad display even after I told him I smelt silicon burning just before it went out completely. He said that he could "depot" the unit and have it repaired for ~$600. Due to the high cost of repair, I chose to purchase a new Thunderbolt Display instead. Recently, I opened the old Cinema Display and found that the Logic Board is fried. I have ordered a new board from 2 different Web retailers. Both accepted the purchase as "in stock" but then stated they could not get the board from Apple. Where can I purchase the Logic Board for a 24" Apple Cinema Display?
Many thanks!

I was very interested to read this document. I think there is a problem with the Cinema Display and that it is frying the computer.
My husband bought each of us a macbook pro. His was hooked up to the cinema display. After about a year, his MBP started to suffer intermittent failures where it would suddenly shut off and have to be hard rebooted. After 2 years, the power or logic board on his MBP completely failed. He bought a new MBP and a Thunderbolt display, and I inherited his Cinema Display for use with my original MBP.
After one month of use with the cinema display, my MBP started to have the same problems. It has to be hard rebooted almost every time I disconnect or reconnect with the cinema display. I went to the Genius bar, and they confirmed that my MBP logic board needs to be replaced; I'm just holding out until spring break to take it back in, as they say it may take a week. Fortunately, I have AppleCare for my MBP.
Our cinema display is 3-4 years old, but it looks like, even though it appears to be working, I should probably get rid of it. I can't keep frying computers!
I'm posting this because I'm wondering how many others are experiencing this problem.

Can I replace a logic board?

So my brother-in-law has a 4 year old iBook G3, and the logic board has gone. It will cost $400 to replace at the local shop; if I can find one for like $150 (which I think I can) is it something that could be replaced easily?

Justin and captainbarred, my advice is to send it to DT & T Computer Services in Fremont, California. They charge $225 (plus shipping both ways) to do the repair.
Installing the logic board is a tricky and difficult procedure. If mine goes out again, it's going to DT & T, I believe.

Can't get new logic board hint to work

after days of trying to resolve my new logic board problem of my time machine back ups not being recognized through using the terminal as suggested, i am giving up for now. i will keep my external hd and the info on it and just back up my important stuff to dvds for now. Is there any other way to get the info off my external hard drive back up so that it would make sense to my computer with a new logic board. Any program, etc.

I assume you are referring to this mac os x hint
http://www.macosxhints.com/article.php?story=20080128003716101&query=Time%2Bmach ine%2Blogic
You need to know some basic unix knowledge to follow this hint. If you can't make it work there is no other way to do it. there are no programs for that either. you should start a new backup sequence. You can still access your old backups via browse mode. control-click on TM in the dock and choose "browse other TM disks".

I have a 24" early 2008 iMac. Can i upgrade the Logic Board?

For some reason only Steve jobs will know this iMac only was able to have a maximum 4 Gb Ram and 512 Mb graphics.
To buy a new one with 32 Gb RAM and 2 GB graphics would cost AU$3,000.00.
Therefore I was wanting to know if you could just drop in a new Logic Board with 32Gb RAM and 2 Gb graphics into the old machine?

iMacs are Not like PC's, which are generic and have commonly interchangeable parts. They are also prone to all sorts of driver conflicts between different versions of hardware that can be installed. Apple avoided all these conflict frustrations by building each model of Mac to a specific, tightly controlled standard "that just works right out of the box". But they are Not upgradeable after purchase except for RAM Upgrades and Hard Drive replacement. That's the tradeoff between getting a PC and getting a Mac.
Hope this helps

Can I get new logic board without serial number? Machine was refurb and so serial on base is wrong

My MacBook is mid 2010 dual 2.4gz unibody white. I bought it refurbished from a company (not apple). It no longer turns on and showed no sign of degradation so I took it to the Genius Bar and they reckon its the logic board.
Problem is that the base on the laptop was replaced before I got it and so the serial number is not the right one and as it doesn't turn on, there is no way of finding it out.
I am wondering if it is going to be fixable?
Thanks in advance.

You need to have any repairs done by the vendor who sold it to you. Usually Apple will only deal with products purchased from them or an authorized reseller.
Motherboards are not "fixed." They are simply replaced.

Where can i buy a NEW logic board for my macbook pro 2012?

My video card has recently failed, in this model video card is sticked to logic board.
Does anyone know where i can buy a NEW logic board? Its a Mid 2012 MacBook Pro

"Where" questions are more easily answered if you give your approximate location. Especially important if you live in the US because there is a low-cost repair option for which you can ask.
If you are out of warranty and you live in the US, the most cost-effective solution is a depot repair. Instead of fixing the computer in an Apple Store, it is sent to a central refurbishment center and they fix anything that's wrong (other than damage to the case and/or display) for a flat fee of around US$325. It takes about a working week but it is worth it. All the posts here from people who have availed themselves fo this option were glowing.

Can i replace logic board mid 2010 with logic board 2011 as newer

The port placement is completely different on a 2010 model and a 2011 model, so the user wouldn't be able to replace it at all.

Logic board swap fw400 to fw800

My 867Dual died and all indications seemed to point to the logic board.
So I swapped the cpu into a FW800 1ghz (shell from parted psu) because they share the same 133 bus.
It works and I haven't had anything strange happen
Anyone else do this?
Now I can use the newer wireless card.
I also want to try this with my main unit a dual 1mhz mdd fw400.
Any reason not to be doing this?

Running fine, and I found out it was the AGP card that failed causing the no start.
Anyways, I have a dual 867FW800 waiting for an airport card

Is there a way of testing the logic board via Terminal?

About 5 days ago, my mac book pro experienced the gray screen flashing folder scenario, telling me that it can't find the OS.
I opened in Internet Recovery mode, and when opening disk utility to check my hard drive, the hard drive didn't show.
After a breif call to apple support, it looked like my hard drive was kapput, so I bought another hard drive (something I've wanted to upgrade for a while anyway).
The new hard drive is a seagate momentus xt 750GB, and fairly sure it's compatible as I watched a youtube vid showing me how to replace the hard drive with the very same drive.
The disk utility cannot find this hard drive either, which means it could be a number of things, the worst being an issue with the logic board..
I cannot open in apple diagnostic mode, but I can access terminal without an OS, can I check the logic board, or anything else that could be causing the problem from there?
I'm trying to find out as much as I can about the problem before I have to pay to get it diagnosed.. hopefully it just needs a replacement SATA cable!
Thanks all,
Joe

Did you format the new drive? This can be done with the Internet Recovery Mode. Try booting holding the command option R keys to get to Disk Utility.

You can run the Apple Hardware Test / Apple Diagnostics:
may not be aware is that Apple dumped AHT this past June. New Macs, introduced in June 2013 or later, no longer include the software. Instead, they have an entirely new diagnostic application called, appropriately enough, Apple Diagnostics. You access Diagnostics exactly the same way as you do AHT: Hold down the D key at startup.
http://support.apple.com/kb/HT5781
New MacBooks can access HardWareTest by rebooting holding the D key, no disk required.
http://support.apple.com/kb/ht1509
or older machines Boot off your Install Disk while holding down the D key, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
If any error codes are generated, post that code back here for interpretation.

Replacing the Logic Board on an iMac G4 (flat panel)

Hi all
A friend of mine has a G4 Flat Panel iMac, and apparently, though I've not seen it for myself yet, her Logic Board died on her. She has since bought an iMac G5. But I've been trying to find where one can get a replacement logic board from, that isn't going to break the bank. I've found nothing so far. Are these available anywhere? And will they be so expensive as to make it not worth the bother? And of course I have not found any technical data about how you open and replace components in one of these iMacs. Apple don't post them since they are supposed to be tampered with only by Apple certified technicians.
Thanks.

Hello,
Apple doesn't typically make their repair components available to the end-user. So, it's a bit harder to find a replacement logic-board for one of their computers.
The service centers can get them, but it's not going to be cheap.
Typically, you can expect to pay $500 to $800 for a replacement logic-board from Apple.
And, the service center is only going to sell it to you if you let them install it.
But, you can sometimes find places that sell them.
This place used to sell lots of Apple logic-boards, case parts, brackets, keyboards, etc. But, they stopped for some reason. But, you might call and see if they have what you need in a warehouse somewhere:
http://cgnusa.com/scripts/default.asp
And, this place does sell some parts for the Do-It-Youself person. But, they typically require you to send in your system for a new logic-board. But, you might be able to get a price from them:
http://www.dttservice.com/index.html
In all honesty, if you are looking for a part you can install yourself, and don't want to pay $500 or more, then you are probably better-off trying to find a used part.
If you can find one who's screen died, but the logic-board is still good on, then you may be able to work out a deal. I hate to recommend them, but e-bay is probably your best chance for a used replacement logic-board. Just don't pay too much.
Whatever route you / they choose, keep in-mind the price of a low-end Mac Mini. Don't spend more to repair an old system than you would spend to buy a current low-end system.
I hope this helps.

What is the part number for my MacBook Logic Board?

I have been searching through all of the Apple forums to help me with my issue. My issue is not knowing the partnumber for my MacBook Logic Board. The sticker that is usually found on the ram slots is NOT there.
The information I have for my Mac is:
2.4GHz/2x1GB/250GB/SD
EMC No.: 2254
Serial No: W8846MGM1AX
I hope someone in the community can help me.
Thanks Ahead of time.

The wegenermedia reference relates to some earlier positive results others mentioned some years
ago, and due to that, I sent an iBook computer to them, in a padded box (over-engineered) that I
made, for diagnostic repair service, and it returned with stickers over the screws that said their
warranty would be void if the tape were damaged or removed. I felt sure enough of their work that
I later sold the computer to an 80+ y/o some miles from where I lived, and chose to give him free
support for two years. That means since he never had used a computer, and saw an ad I put on
a bulletin board in that town and chose to reply to it, I even went as far as helping set up printers
and other things he had never done, at no additional profit to me. The iBook was a complete kit
and included original box, plus later OS X and extras, at below other location retail.
I've been in contact with them about two other computers I have, one is an aluminum PowerBookG4
and the other a MacBook1.1 13-inch 1.83GHz first-model, each has issues. The MB1.1 is better, &
it only needs some parts to fix two issues, but it runs well. An occasional winking display, that does
best if left sitting with lid open; and by use of iStat Pro, I see odd information from the CPU temps on
one of the two cores in the processor. Sometimes, it says the core is sub-zero °F, other times hotter
than the other one. And also, it may disappear from the reporting to iStat altogether. So that may be
as simple as a need for new thermal paste if the CPU could be so doctored. They will inspect and
test an item before a firm cost estimate is arrived at. They've also workstations to repair logic boards.
So I'd be willing to bundle up my early MacBook1.1 1.83GHz and send it off for a $200 service, since
once it is opened most issues can be dealt with on the spot, and it would be returned with warranty.
Since my example is a clean one, it may be worth that service. It has 10.5.8; could run 10.6.8 OK.
Anyway, the discussion is a bit afield from the OP topic, except there are experts who can repair an
original logic board; some prefer to see and test the entire machine. Others may swap out the board
for one they've already serviced if available, for turnaround-time sake. They offer older refurbs, too.
Between the sales model number and processor version it should be easier to locate a replacement
for the original post's questionable part issue. Some devices had additional part numbers that may
work, depending on the length of product run and changes in manufacture over the duration.
{Seems to me you'd gone from using Macs awhile, to PC, and were in state of ID awhile, btw.
And the reference email I have, is your first + last name at gmail.}
In any event...
Good luck!

Which logic board do I need?

I need to buy a replacement logic board for a PowerBook G4 15"...what are the specs for which one I should buy?
My laptop's Model Number is UJ-825-C and Serial Number is W84424JFQHY.
Know where I can get a cheap logic board?

UJ825C should be the number of the DVD drive. If you click the blue apple and about this mac, that will tell you what the processor speed is. If it's a 1.67Ghz system, click more info, and memory, and if it says DDR2 memory (versus DDR) then you have the last model of the Powerbook, sometimes referred to as high res or high resolution for it's video (and the other 1.67Ghz system, with DDR memory are sometimes referred to as low resolution). Some boards may have a choice of 64MB or 128MB of video memory.
There are several vendors that sell used logic boards, two of which are http://www.ifixit.com and http://www.pbparts.com .
