PowerPC :: Use Different Processors On Motherboard?
Jun 24, 2008
I was recently given a non working G5 dual 2.5ghz machine. It is a quad core machine with the Delphi liquid cooling system. After some investigating I found it had a coolant leak. All the fans and lights come on as well as the bootup �chime�. I think (hoping) that the motherboard and power supply are still good. My question is this:
Can I use different processors on this motherboard? Lets say a dual 2.5ghz non-quad core processor assembly. Am I making sense? I am very new to the Mac world and would appreciate any help on this issue.

I was recently given 2 Powermac G5's,one of them works but the case itself looks like it was dropped out of a window,it is a 2.0DP and the second is a 1.8DP that isn't working but the case is nearly perfect.Would there be an issue with swapping the 2.0 into the 1.8?

I have Powermac G4 AGP (M7628LL/A) that has the AGP slot without the 'power-supplying' tab at the front of the slot. Therefore my NVIDIA GeForce2 MX video card (ADC/VGA) will only enable me to use the VGA outlet, and not the ADC. I have two Studio Display Monitors (M7649) and cannot use them.
I need to know (1) What other monitors will work with this G4 (in case I cannot fulfill #2), and most importantly (2) Which motherboard can I replace this one with that will enable me to use the video card in it's fullest?

I bought 4 G4 towers of eBay for �85.. none have Hdd's so havent tried them out yet (two also have no graphic cards) I got a mix of ram size and speed (pc100/pc133) however thats not my question
Next to the ram slots theres a red light that comes on, is this normal? I've tried to do some research on it and some people say it is, others say it isnt.
I plan to sell them off again on ebay but I did it mainly as a project to keep the G4's alive. Any suggestions on graphic cards (cheap ones too)?

I'm looking into replacing a motherboard on my newphews iBook G4. It's an early 2004 Series. I'm wondering if these Ibooks have interchangable motherboards, i.e. 1.0ghz vs 1.2ghz, 12inch screen vs the 14inch screen. I've done much work on IBM compatible laptops and these interchange pretty easily...but these MAC's are all new to me. I'm looking to get a busted up one off ebay and replace it for him for pretty cheap...

Ok, my problem is as the title states. Why is this happening? My motherboard had 8gb slots and is compatable with 8gb ram. I installed 8 dimms of this ram I bought from newegg: [URL]

I recently upgraded my powermac G5 dual 2.5ghz from tiger to leopard and for some reason it is no longer showing "dual" under "about this mac." In addition, under "more info" where it says number of cpu's it only says "1." Is there any way to fix this- is there a way to look in the bios and confirm that both processors are working correctly?

Recently I didn't do my research, and I purchased a Quicksilver power supply to put on a Gigabit machine. I noticed it had four extra pins which look like some of the ones they use to power processors in some PCs (tho I've come to find this is for the ADC port). I dug a little deeper (Googled "powermac_g4.pdf") and found out that some of the pins have differences between the Gigabit PS and the Quicksilver PS.
Has anyone else had an experience like this? Will the PS work without any wirecutting or do I need to get a new one?

I have a replacement motherboard (G4 MDD 1.25 dual) coming in and even though I have a very talented and technical friend coming by to help, it'd sure be nice to have some instructions on removing the current motherboard and the subsequent install of the newer one. Mine is having kernel panics about 98% of the time on attempted startups and I've tried (along with the Apple Store Genius Bar) everything I know how to do or have Googled and read. I think it's perhaps a USB bus issue.
I did manage to get it to boot from the Apple Hardware Test and everything passed. And, one of the USB connectors on the back of the machine is damaged, so I figure a complete motherboard swap should eliminate all possibilities except for maybe the CPU which seemed to pass. So back to the original query. Are there docs somewhere to guide one in the removal of the motherboard? I run a recording studio with this machine and I'm dead in the water! I am looking into either a new MacIntel or possibly a used G5 to replace it with.
G4 dual 1.25 MDD Mac OS X (10.4.11) Recording Studio

While taking apart ibook to replace harddrive on grapghite 466 , I ran into trouble. In taking out the backlight cable, the whole plastic receptor (little white plasatic at J4) on the motherboard came off as well. This is a little part (1/4 x 1/8inch). I can't tell if it was soldered on or just slips on the motheboard since tiny bits of plastic broke off. Can someone tell me if/how this can be repaired.

I recently acquired a used G5. When I look at "about this mac", it tells me that I have a two processor, 2ghz machine but when I open the case I only see one G5 icon. The serial number is from late 2005. I just wanted to make sure that I have two processors as I'm planning on selling/trading up to a mac pro.

All I can find is an old article that details how to get the 2ghz quad core processors into a Mac Pro. Any reports on using the newer processors in the 1st gen Mac Pro 2.66?

So the new MacBook Pro 17" can have 8GB ram and New MacBook Pro 15" can't anyone figured out way it is that way, cuz only difference I can tell is the new processors but those don't matter with memory it is the chip and as far as I can tell is the same unless apple is not saying something. I don't have $1200 for 8GB of Ram anyway, but be nice to know my new MBP 15" in a year when the prices are lower can have 8GB Ram.

I'm about a year into the Mac platform after switching from pc. My first Mac was a 17" MBP and I'm looking to get a Mac Pro. Like most I'm waiting to see when the new ones will come out. I have always been curious and just wanted to know can the processors be swapped out like on a pc? I realize this involves mother board issues and whatnot but the processors we're waiting for are the same ones that can be purchased by anyone. I always wondered why someone with say a 2008 Mac Pro could not just simply swap out the processors since the tower itself is still the same. Again, I'm fairly new but just was wondering if anyone knew the answer (s). Thanks again for any insight as I'm trying to really learn and understand the Mac system under the hood so to speak.

I am looking into getting a new mac. I am a photographer and my major concern/application is Photoshop. At this point in time apple will be releasing (soon I hope) new models. When they come out, I believe I will have the choice of finding the current models somewhere or getting the just released products. Money is a little bit of an issue. I would like to keep as much of mine as possible and give apple as little as I can. That being said I have no problem investing what I need to. I just don't want to waste on something that isn't going to give me any real gain. Like i said I mostly use photoshop. will photoshops usage of multiple processors equal the cost or should I save the money. Purchase the a quad or what ever they release ( 6 core) and put the money saved into memory and ssd drives or drives.

Can you upgrade the processors in the new Mac Pro's in the future if you choose to?
I have seen a couple people mention to but the 2.6 for now and upgrade them in the future when the price of the processors drops.
I didn't know if I was misinterpreting what they were writing.

If I purchase an i5 or i7 iMac in a years time could the processor be swapped for a faster i5 or i7.
I know the iMac take part looks hard but it can be done so can the processor be popped out and replaced?

Today I ran msconfig and checked out the the boot tab.. I saw I had only 1 processor selected (default) there for booting. Does changing it to 2 processors help overall booting and general performance? I am on MBA Rev B and my bootcamp partition has win 7 Profesional 64 bit.

I am considering buying a new Mac Pro. Can anyone tell me that if I buy one with single CPU, can I upgrade it later by adding another CPU? In other words, do I get a dual CPU motherboard or not?

I just ordered a Mac Pro with Two 2.8GHz Quad-Core Intel Xeon, 2G of memory, 2 500G hard drives and I am wondering it is possible to upgrade it to 3.2GHz more cost effectively then buying it from apple directly during the purchase of a computer or even post purchase?
Also my unit came with 2 500G HD's, this comp is the lifeline for my webstore, web design and storage for all my personal stuff. So i am wondering if I should just buy 2 more 500G drives for roughly 80-90 a drive(memoryamerica.com) and a Raid Card to back up the first 2 500G drives or just buy a Western Digital 1 or 2 TB external OR buy a 1TB Time capsule.
The sole reason for the external or extra internal drives is in case the first 2 500G drives fail I don't lose any data.
Lastly, I bought the basic ATI Radeon HD 2600 XT 256MB card to run two monitors(one for the webstore, one for web design, photoshop and Adium or anything else I would use on the daily). I plan on putting in as BR drive(i know Leopard does not support it) but I was looking to use it for burning BR movies, and if need be run MV(microsoft Vista) to view/copy and burn BR movies(the two screens I am getting are HDCP), i am afraid this card does not support 1080P BR data, does any one know which one will?
I have talked to a Mac Genius and got no real info do to me wanting to use non Apple components IE non apple supplied HD's, memory(buying a 8G memory kit from Memoryamerica.com to reach 10G of memory) and BR drive and Dell Monitors(more cost effective and supports HDCP/BR)....
