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

I followed your instructions and installed Developer Suite 10G on Windows Vista Home Premium edition. I have Oracle 11G DB running on the same machine.
Two points, Steve:
1. When I tried to set the maximum virtual memory to 6110 an error message displayed from Windows and told me that I can't set the maximum virtual memory to more than 4096. I set it to 4090 and it worked and I got nothing wrong during the installation process.
2. After installing JInitiator and disabling Java on Firefox I called the http://127.0.0.1:8889/forms/frmservlet page and everything seemed to be OK because the Oracle Forms Services logo appeared and then a successful installation message appeared , but as I clicked (ok) to continue a gray screen appeared inside the browser (like the one displayed when you try to run a Java applet inside a browser) and then I wait to death till something appears but sadly nothing. I just get a blank gray screen inside my Firefox browser.
Do you have any idea what to do to solve the problem?

How to erase a early 2008 iMac Hard drive when the screen is dead

My early 2008 iMac's Graphics Module has died for the third and last time. I want to erase the Hard Drive before I offer it up for sale as parts or just re-cycling. But with the Graphics Module dead it will not boot up, therefore no display. So how do I erase my data and restore to a clean OS?

Make sure that your old Mac will boot into disk mode then buy this Thunderbolt to Firewire Adapter

Early 2008 Mac Pro 3,1 Mystery Logic Board/GPU Issue

I recently received an Early 2008 Mac Pro 3,1 for free because the owner couldn't figure out what was wrong with it. It would boot up with the startup chime, but never output any video, and kept rebooting and replaying the startup chime. Using the diagnostic LEDs on the logic board, I was able to see that the Power Good LED (LED 7) and the EFI LED (LED 9) were both on, but the GPU LED (LED 8) never lit up. After trying all the PCI slots and confirming that the graphics card worked in another Mac Pro, I confirmed it wasn't the graphics card. I then tried a different power supply and different power supply cables, different RAM, different RAM boards, but still nothing. (Note: I also went through all the usual stuff: Power Cycling, PRAM, SMC Reset)
I then ordered a replacement logic board (used from eBay) and spent the weekend swapping out the logic board. After the swap, the Mac Pro STILL won't output video, and now the EFI LED (LED 9) won't even light up. Tried resetting the EFI Firmware via a CD, and still nothing. Does anyone have any idea as to what the issue could be? I'm 95% certain I plugged everything back in correctly on the board, but I don't know what else to do other than tear it apart again to confirm everything is plugged in. The only other thing I can think of is that the second logic board I received was also bad.
Please help!!!

Your problem sounds like a graphics card problem to me.
confirming that the graphics card worked in another Mac Pro,
Was this also a Mac Pro 2008 model? was it running the same Mac OS X version as you are testing? what version?
what graphics card are you trying to use? Genuine Apple or flashed PC or unflashed PC? what Mac OS X version?
That second board sounds Bad to me if it won't say EFI-OK.

I have an Early 2008 Macbook, can I upgrade to OS X Mountain Lion?

Please advise. Thanks

To Upgrade to Mountain Lion... Your Mac must be one of the following models:

I have a hp dv7-1020us. Can I upgrade the CPU and if I can what is the best I can obtain?

Just recently my hp dv7-1020us CPU performance has drastically been reduced to the extent that it runs at 75 to 100% capacity all the time. It is very noticable when accessing the internet. At times my screens take up to 60-seconds to change/refresh. I see "not responding" on most web pages accessed.
I had heard that possibly a CPU upgrade would correct the issue. What I have done most recently is upgrade the memory to 8gb, installed W7 Home and also downloaded IE9. The performance issue was noticed before I made all those changes. I have two hard drives installed, both are less than 50%. I have contacted the cable company about my cable router and they have remotely tested without any issues. I have also been runing daily virus scans to see if a virus has possibly infiltrated my system. I even re-installed my previous wireless router and there was no remarkable change.
If anyone has any ideas or solutions please let me know. I am actually looking at another computer, the dm4-3090se as a fix but don't really want to spend the money. I also have a small Asus netbook with 2gb's of memory that runs faster than my hp. My phone even accesses web sites faster. Again, if anyone has any ideas please share!

Hi:
If you are interested in upgrading the processor (which may help only a little--depending on what processor you currently have), below is the link to the service manual.
http://h10032.www1.hp.com/ctg/Manual/c01918142.pdf
Supported processors are listed in chapter 1, page 1.
Normally when my PC's begin to get real bogged down and I have maxed out the memory as you have, I back up my files and reinstall the operating system, and get a fresh clean start.

Can we upgrade the wireless board in T42?

I have revitalized my T42 by upgrading the hard disc and memory. Since this machine primarily is for internet, the wireless is very slow. It is only 11mbps. Annway that we can upgrade it?

I have a 24" mid 2008 imac when i plug the head phone jack into my stereo i have a hum that never goes away.

i have tried grounding both the head unit and also the computer it self and all i find is the noise is still there. what can i do to get rid of the noise? i think the problem is in the grounding of the head phone jack it's self but i dont know. has any one else had this same problem? thanks for your time.

How did you confirm grounding? How old is your house? Does it have 3-prong outlets? If not, there's no guarantee they are wired right even if they are the ones with one wider prong slot. If they are 3-prong, that's still no gurantee they are wired right. You would need one of the below to be sure. Just trying to save a lot of troubleshooting of devices when it could be your house wiring.

Problem installing Win7 64 bit on early 2008 iMac 2.66 GHz

I have read posts elsewhere that, contrary to what Apple says, it is possible to install 64 bit Windows 7 on an early 2008 iMac 8,1. The problem I'm having is that I can't get the iMac to boot from the 64 bit Windows 7 install disc. The error I'm getting is "Bootmgr is missing". I can view files on the disc just fine when I'm in OS X, so I know the bootmgr file is on the disc. But it refuses to boot from it. I know this hardware can support 64 bit cause I can boot OS X 10.6.2 into 64 bit mode.
Anyone else run in to this? Thx for any help.

Thanks Hatter. That did the trick. Actually, the link you sent me lead me to this site:
http://blog.andersonshatch.com/2009/01/11/windows-7-x64-on-a-macbook-pro-guide/
That site links to this:
http://test.andersonshatch.com/2009/11/08/select-cd-rom-boot-type-prompt-during- vista-server-2008-r2-windows-7-x64-boot-on-macbook/
and that's what I used to create a DVD that was bootable by my early 2008 iMac.

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.

We have an early 2008 imac and we realize it is not long for this world but we would like to get a few more months out of it until we can afford a newer one. Can we put in a larger hard drive and add some memory?

Would it be worthwhile to put in a larger hard drive and boost the memory on our early 2008 iMac? We realize it is on borrowed time but we would like to squeeze a little more time out of it.

Problem description:
This iMac is running awfully slow, and freezes up often

I have Garageband version 4.1.2 (248.7) installed on my early 2008 IMAC Version 10.5.8. I have never upgraded but have a LOT of projects. If I upgrade my operating system to the next level (10.6?), will my GB version still work? Do I need to upgrade GB?

I have a LOT of projects involved and hope they will transfer. Can I (and should I) upgrade GB at the same time and how far should I go with that without causing a problem with my projects? What would I gain if I upgrade GB? Thanks!

the only version you can buy new is v6,a nd it should open older projects without issue ... however you could keep 4 around:
