Chosen Solution
I have a 2008 24" iMac with EMC2211 Reboots randomly. Most of the time stuck in boot loop (cd-rom sound first, then no post, 5 seconds, then cd-rom sound, no post, 5 seconds, then cd-rom sound, no post, etc). - Type “A” boot loop Sometimes stuck in boot loop (starting sound, bootup screen, reset, starting sound, bootup screen, reset, etc) - type “B” boot loop Attempted all the “usual” resets, unplugging the power cord, replugging. This will usually make it go past the type “A” boot loop, but causes type “B” boot loop. Trying the keyboard shortcut reset (command/option/fn key? or whichever keys they were) doesn’t achieve anything. Tried installation disk, but iMac took forever to try load the disk, and in the mean time, reset and got stuck in type “A” boot loop. MacStore said logicboard needs to be replaced. Can I replace the logic board of the 2211 with this: A1225 2008 logic board 820-2301-A? Thanks!
Ameel, trying to help you figuring this out. Your computer is the EMC 2211, right? That would make it either a 2.8GHz or 3.06GHz with the following general specs:" 2.8 GHz Core 2 Duo (E8235) Intro Date: April 28, 2008 Disc Date: March 3, 2009 Order No: MB325LL/A Model No: A1225 (EMC 2211) Subfamily: Early 2008 Model ID: iMac8,1 Std RAM: 2 GB Std VRAM: 256 MB Std Storage: 320 GB (7200 RPM) Std Optical: 8X DL “SuperDrive”. The logic board you can get is a 820-2301-A, correct? 661-4666 2.8GHz which is the 820-2110 iMac 24" 2.8GHz Core 2 Duo (A1225) - Mid 2008 661-4667 3.06GHz which is the 820-2301-A iMac 24" 3.06GHz Core 2 Duo (A1225) - Mid 2008 So, it does look like it is just the processor that is different. Same model, same year, so yes, there is no reason why it should not fit. Hope this helps, good luck.
If you mean move from the 2.08Ghz to the 3.06Ghz version yes. As long as you stay in the same model year the logic boards are just variations, or customizations of the base board. If this answer is acceptable please remember to return and mark it.
