This iMac originally came with a 2.8GHz processor, in this tutorial I will upgrade it to the maximum 3.06 GHz processor.
Keep in mind that this “example” upgrade is not very economical since the performance gain is only minor.
Time and effort involved in replacing an iMac CPU are significant.
Even with an upgraded CPU, this early 2008 iMac will not support macOS High Sierra.
A lack of SATA III and the inability to upgrade the graphics card severely limits this machine's performance.
Having said that, I always enjoyed using this computer!
Even at 10 years old it performs well at most everyday tasks.
Especially browsing the web, watching movies and so on.
On the one hand, this system has a nice large 16:10 display, which is great because most displays today are only 16:9, on the other hand, I found it to strain one’s eyes after prolong use. Some modern displays may be significantly more gentle to your eyes.
Also, notice the in my opinion thermal constraints that ever flatter iMac's seem to have.
If you can’t open it easily, how will you be able to prevent dust from clogging up your cooling system over time?
While the iMac 8,1 uses the "Socket P” unfortunately more powerful quad-core CPU’s such as the "Intel Core 2 Extreme QX9300" will not work in this system. Therefore the fastest supported CPU is the “Intel E8435 Core 2 Duo LGA478”.
In summary, I love the iMac, but obviously, it has some downsides to it as well.
I hope this video did help you to learn more about computers, and macs in general.

I recently disassembled my 2008 iMac and replaced the SSD. I like the detailed style of tutorial here, especially showing the components and explaining how the air flow looks like there.
Thanks much!
Glad it helped!
My Macit's somewhat slow, should I also change the SSD? or is it best to upgrade the CPU?
@@filoshi First of all, which Mac is that? Recent Macs are almost non-upgradable, but it depends on a specific model. Second: CPU update is a more intense task and needs more dissasemble (not every model can have it upgraded either).
SSD update sounds like an awesome idea to quickly fix a Mac and prolong usability for a year or two.
@@NomadicDmitry it's probable the same you used for this video. Late 2009 if I remember correctly
@@filoshi I've used Late 2008 iMac. Yes, you can upgrade SSD there. CPU upgrade is probably worthless on those machines.But expect to get 1-2 years more of the system. It's very old, only for basic tasks.
Another option to get some speed improvement is install some Linux distro there instead of Mac OS. It should work faster on that old hardware. But honestly I would just upgrade the SSD and buy the newer computer within a year or so.
I used the Dosdude patch and upgraded my 2009 iMac to Mojave. Works great.
I have the same iMac from 2008 and iLOVE it ;), just upgraded the hdd to ssd and ram to 4gb
Does it let you upgrade the software after memory change
did the performance improved ? how much?
@@johnbaker4826 That isn’t how it works.
i upgraded mine so much its at 24 gb lol
did u have to back up your files and software?
Yeah, I'm gonna upgrade the ram. Awesome Job.
Thank you vwry much fir the screw overview. Helped a lot🙏
I recently did an ssd upgrade in my 3.5 year old iMac and it was surprisingly clean inside.
That's great, it can depend on the environment and how much you use the machine, mine was in use a lot, plus for some reason, there always seems to be a lot of dust in my room, other than that I since switch to an Early 2009 MacPro ➜ czcams.com/video/Dv73HrnsNkw/video.html
Much more powerful for my daily video editing, and very easy to upgrade in comparison.
I just been told by a computer shop in Plymouth UK - a CPU upgrade is not possible on an I mac - and if it is - it is too cost prohibitive due to the cost of other parts required.
I think the newer model iMacs have a glass panel that is hold in place with adhesive. So I would definitely check your exact model, maybe have a look here ➜ www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2546+CPU+Replacement/15764
Personally, since filming the video, I have switched to a used 2009 Mac Pro, because they are more powerful and much easier to upgrade:

Thé thermal paste looked good.
Good video but please briefly what are the advantages up upgrading the CPU
The speed increase was only minor, that's why I switched to a used MacPro (Early 2009) that is much easier to upgrade, especially the graphics card ➜ czcams.com/video/Dv73HrnsNkw/video.html
@@ReviewTechTV I love this mac but it feels too slow for me...But it's such a great machine, I wish I could continue to use it in a satisfactory way but if you are saying that for you it was best to switch to a different MAC... should I just so the same and give this computer to my mom? I sometimes like to edit videos and such so I need a somewhat powerful computer form time to time. Thank you for your help
Hi! Thx for the video. One question. Would the CPU replacement work with an early 2009 20" iMac? I have replaced the HHD with an SSD and upgraded the RAM to its maxed 8G. I am running Mac OS Monterey with the Opencore legacy Pacher, but it has recently begun running a bit slow. Any advice? ; )
I recommend you look on iFixit cause they have iMac Repair Guides for all models:

Does upgrading a CPU for iMac late 2015 21.5inch workable? Wondering your CPU doesn't need soldering? Also, how can I know which CPU works for my iMac also?
Great Job keep up the great work !
Thanks, will do!
I'm Brazilian, I would like to see it with a quad core, if you can make a video I would appreciate it
Quad Core will not work!
Only the dual core CPU in the video is supported.
so is the cpu socketed or soldered? also does one need to back up all files and software when doing this procedure and swapping ram?
about better performing graphics cards, for the Imac. there are several types that work perfectly. they are from alienware laptops. The lowest price one is GTX 765. This is a two gig card, and will run most video games. The next is a gtx 770 with 4 gig, and will play even demanding games. The most expensive, ($350.00 + shipping) and has 8 gig, so will play with all the shaders and rez on the most demanding games. The 765 gtx 770 can be had for around 100.00 dollars. This will make your imac truly up to date.
Awesome, I am glad you found a card that works for you!
Actually, I did switch to a 2009 Mac Pro last year, because I wanted something more powerful for 4k video editing ➜ czcams.com/video/Dv73HrnsNkw/video.html
That works with a early 2009 3,06 24”?
@@sergiojesus7781 from mid 2009 to late 2012
I wonder if iMac 9,1 would support quad CPU like QX9300?Mine is 20inch, Early 2009,now it's 2.66ghz core 2 duo.And would it be upgraded to a better GPU? It's nvidia geforce 9400 256mb.
did the creator ever make a quad core video?
You cannot use quad-core, the iMac BIOS/Firmware doesn't support it, I don't recommend upgrading this machine anymore, it's too old at this point.
Will a i7 processor work
I have the iMac at the end of 2009 10.1 core 2 Duo,
what type of processor do you recommend that I finally buy to boost my iMac.
I don't recommend this upgrade anymore, the computer is now too old to upgrade.
Hi, I have the iMac 27-Inch "Core i5" 2.8 (Mid-2010) I deleted Mac OS and installed Windows 7 for my wife due to PC software requirements. But now, I want to revive the Imac to its full potential. I would like to know what can be upgraded as to make it as much powerful as it can and run it on Mac OS
I wouldn’t recommend this upgrade anymore, because at this point 2022 I find the iMac graphics card is simply too old.
But you can find detailed information here -> www.ifixit.com/Device/iMac_Intel
@@ReviewTechTV First thanks for the reply and also thanks for the advice, I just had a bit of nostalgia, lol
Hello, will a core 2 duo t9800 or t9600 fit into this computer?
Additional information in the video description.
Can a CPU upgrade for an iMac (early 2011 i believe - A1312) allow a higher version of iOS be installed / ran?
According to Apple the max supported is macOS High Sierra
support.apple.com/en-us/HT201634
A CPU upgrade has no effect on the supported operating system.
@@ReviewTechTV yes I read that. High Sierra is no longer available for reinstall through official Apple, but it's possible to get a working (bootable) copy, & install it fresh. Or if possible try Big Sur, maybe Catalina, if either will work! Thank you 🤓 I found the A1312 in a dumpster recently and did an Erase function, then tried the Reinstall function from the utility menu, but no luck.
@@ReviewTechTV just better performance?
is this upgrade possible in a , iMac (21.5-inch, Late 2013) and if it is, would it be easier than ths.

I got hold of early 2008 imac 20 inch came with 2.6 GHz 320 GB hard-drive 2 GB ram I brought month ago it was very clean when I open it. I have upgrade my hard drive to 1 TB and ram to 4 GB. Can CPU be upgraded on this system
If you have a different iMac than shown in the video you can most likely find a repair guide here ➜ www.ifixit.com/Device/iMac
Can I use a core 2 quad q9000 in my 9,1 imac?
Will the T9900 chip work in the 20inch iMac ? The bus speed is different. My Mac has 800Mhz bus speed and the chip you used is 1066. Thanks.
The hardware tends to differ based on iMac model year, please compare on websites like:
➜ www.ifixit.com/Device/iMac_Intel
12:00 Think of the AMD GPU failure in nearly all Apple Macs. It's all about thermal issues, regardless how many fans you have or how careful you are. I never would any used Mac without PCIe 3.0 4x + NVMe Support. IMO this is the most important spec at these machines. The CPU doesn't matter so much...
Many people use Macs Fan Control, that way I had no thermal issues at all, even after using the iMac for many years. Having said that, I switched to a used Mac Pro 4.1 (Early 2009) model and did a few upgrades such as NVMe ➜ czcams.com/video/fo7lVMfXq1c/video.html
what is the quad core processor called?
i would like to upgrade it
Honestly, even if you could upgrade to the faster quad-core, I think it would not be worth it because you are limited to the old GPU of the iMac. Recently I bought a used Mac Pro, early 2009, from eBay, and it was much easier to upgrade everything. ➜ czcams.com/video/lJF-rffIyq0/video.html
@@ReviewTechTV cant change the GPU too? :(((
Does it work with 20 inch 2008 iMac (MB323LL/A)
I don't recommend upgrading hardware this old anymore.
So I have two mid-2009 imacs (20inch- and 24inch) . This cpu is the max CPU for them correct? I need to repaste the terminal paste but I guess it would be best to replace the cpu as well.
It's probably best to look at the iFixit website because depending on the exact model it can be different:
➜ www.ifixit.com/Device/iMac_Intel
@@ReviewTechTV Thank you for the link! I have ordered the cpu and will do the upgrade this week. Pray for me lol
YES, QUAD CORE PLZZZ!! i want to put one in my 7,1 imac!
Your 8,1 has a 1066 bus speed? Mine is just 800mhz.
But i did hear that you can run some 1066 cpu in it. But then the cpu might not be running at 100%, im not sure. :(
Too bad about the GPU situation...
The quad-core won't work, even if the hardware could support it, my understanding is that the BIOS doesn't have the CPU microcodes for it!
@@ReviewTechTV omg someone needs to try it... It would be amazingg if it worked!!
Ive seen people run chips in them that were un-reconised but still worked!
I thought maby it might run on the same code as some of the dual core chips since its not a true quad core.
Dangggggg thanks for the reply tho! I might still have to try it lol
Shame about the GPU i reallyyy need more Vram. Maby do a video about upgrading :p i know you covered it a tiny bit here but... :)
Cheers
@@ReviewTechTV maby one of those external video card setups?! Just thinking out loud.
Altho im not keen on that idea i would rather buy a chip from another mac or whatever. Too bad about the priceeeee :(
Dunno but ive been hearing whispers that it MIGHT be possible lol
Does these work with the 20 inch model
Since the iMac models can differ significantly I recommend you look for a tutorial here:
www.ifixit.com/Device/iMac_Intel
How would core 2 due x9100 work? And would a video cats for the 24 inch work floors the 20 inch?
Nope, only the CPU shown in the video works, faster quad core are not supported.
@@ReviewTechTV this is the fastest dual core. Also ive read in some forums of quad core working
SO I have the imac 20inch / early 2009 - 2.66ghz / geforce 9400 256mb - what can I upgrade it too?
Ok, according to iFixit this are possible upgrades:

Is it possible to upgrade the processor from i5 to i7 on imac 2017 27" 3.0Ghz Radion pro 570?
I checked on apple site on the 2 other of 27" its written configurable but not on the 3.0
I was torn between 21" and 27" model and the most important key factor is to be able to upgrade in the future.Many said to buy the highest gpu and there is amongst the 21"model imac that can be upgraded into vega but im not sure if anyone can upgrade without removing the whole motherboard.
all of the imacs have socketed cpus
this iMac works with Core 2 Quad? I have also.
No, only the dual core shown in the video works, quad core CPUs are not supported.
That’s bullshit! That’s mean PC is better in Core 2 Era being able to support quad and extreme! I don’t know why people would buy an iMac when they can get better spec on the PC
what is the heights CPU can supported by this P.C ? Thanks
Answer already given in the video description.
@@ReviewTechTV thank you so much
Would a core 2 quad q9000 work? I want to upgrade to that and either an 8800 gs or gt 130 or Radeon hd 3670
No, a quad-core CPU won’t work, the 3.06GHz Intel E8435 shown in the video is the fastest one you can upgrade. Also please note that I don’t use the iMac anymore, with the release of macOS Mojave it simply became too old. Instead, I got a used 2009 Mac Pro from eBay and upgraded it instead.

Can you use any processor for this upgrade from another pc?
Only certain processors can be used, see video description.
I don't recommend this upgrade anymore, I switched to a used MacPro instead.
So is the iMac faster? is it better for video editing?
Unfortunately, it was only a small increase, because of that I switched to a used 2009 Mac Pro instead ➜ czcams.com/video/lJF-rffIyq0/video.html
In my opinion much better for video editing than an iMac, and much easier to upgrade as well.
My 2008 iMac i've had since new (24" 2.8 extreme processor) does a much better job of iMovie than my 2014 MacBook Pro...
Nevermind i got it but will the q9000 work in the system
No, the quad-core "Intel Core 2 Extreme QX9300" will not work!
@@ReviewTechTV I'm helping my mom upgrade her iMac 8,1. We upgraded the hard disk drive to an SSD, and we maxed out the RAM to 6 GB. She has the 2.8 GHz stock E8235. I'm trying to determine the fastest CPU we could upgrade to. 3.06 GHz 8435 (what you upgraded to) seems like the fastest CPU Apple offered with this Mac. When you mention the quad core model, you're referring to the Q9000? But you mentioned the Q9300 doesn't work? Do you have a list of supported processors? I'm considering the T9900 or the Q9300 if one of those would work, as they seem like the fastest models. Any advice on where to identify which CPUs are supported by this Mac? Great video, thanks for the information!
@@AdamJaz That's a great question, maybe have a look at the MacRumors forum, I recently got a 2009 Mac Pro, and upgraded it, they had a great CPU list for that ➜ forums.macrumors.com/threads/mac-pro-cpu-compatibility-list.1954766/
Having said that, I would stick with the 2.8 GHz, because the perforce increase I got from the 3.06 GHz was only very small. Even if the hardware could support faster Intel quad-core CPUs, the iMac BIOS (EFI, Boot ROM) will not support them… hence it is not worth the trouble.
Take my used 2009 Mac Pro, for example, it needed a BIOS (Boot ROM) update before it was able to accept newer and faster Xeon CPUs. Essentially, CPU microcodes are sometimes changed and updated by Intel, and then these updates have to find their way into the Apple Boot ROM, which is usually included with the macOS installer.
@@ReviewTechTV aww too bad :/ Well, Ill just use the x9000 then since I have two sitting right here... at least I can overclock in windows, and hopefully in OSX too. They work great in my acer laptops of that era!
I have to say that I wish Apple would add a little thickness to the imac and macbook pro. I'd rather have more bulk and better cooling. If someone wants a tiny mac let them buy a macbook air.
Cut out a panel on the back, attach hooks, so you have easy access to hdd and can open up for extra cooling. if properly sized (140x140mm) you can even hook up a secondary fan you can power via usb
@@DerFliegendeMocca I guess I could build my own laptop. That's a novel solution too.
Thinner = hotter : (
you skipped over the important parts!
Is it possible to install a core 2 extreme in this mac?
No, Quad core CPU is not supported by the BIOS, max CPU is shown in the video.
Due to age of this iMac I don't recommend this update anymore.
@@ReviewTechTV Never had an apple computer before, but I bought an 8.1 3.06Ghz iMac for 9 pound, so I decided to see what it can do and how far it can be upgraded.
@@gamingdad2549 I would focus on the SSD and RAM, however the main limitation of Mac's that old is mostly the GPU and operating system.
@@gamingdad2549 For upgradability you can also look at: www.ifixit.com/Device/iMac_Intel
How can I know what's the max CPU I can put in my iMac (2008 20")?
The system is too old now, I don't recommend the update anymore!
Doesn't 'too old' depend on what you are using the machine for - and what OS?
If not doing gaming, video rendering, etc. an upgraded older iMac should be quite usable, no?
Linux would also run well on an older machine, correct?@@ReviewTechTV
Are there any quad cores that will work
No, the Intel DUO core is the maximum supported by the system/BIOS.
I don't recommend upgrading this old machine any more.
Newer iMacs have much better and efficient cooling design. It was redesigned completely without optical drives, with new much thinner and cooler display panels, and with low-power storage. So most of the heat comes from CPU+GPU, through one big radiator.
It is also available in double-fan design like iMac Pro in practically same enclosure.
Too bad it doesn´t work with Intel Core 2 Quad Q9100.. This apple guys are really bad by limiting their Bios to use only duo core processors. Is this a MacOS or hardware limitation?.. I use linux Mint on mine Btw.
Apple's limitation on using only dual-core processors in some older models is a result of hardware design choices and macOS optimization for specific hardware configurations. It's not necessarily intentional but might be due to compatibility issues with the motherboard and chipset. Older hardware becomes incompatible with newer operating systems due to changes in architecture and optimizations for newer components.
anyways for change the gpu ?
Nope, and changing would not makes sense anymore in my opinion.
Can this be done on the 20”?
I am sure there is a tutorial for it somewhere, but at this point, I wouldn't recommend it anymore.
Because with the release of macOS Mojave, you need a graphics card with Metal support.
That's why I abandoned my old iMac and switched to a used 2009 Mac Pro, which works much better because you can easily swap out any hardware ➜ czcams.com/video/lJF-rffIyq0/video.html

the fans in the newer iMacs is better
No it's not. Had 3 iMacs and I'm writing this on one I've had for almost 11 years. The two newer ones all failed just outside of applecare warranty...
nicely explained but too much talking, you can for sure get more to the point in some part to reduce the video to 15min and showing how to take the CPU out and putting the new one was what I expected and only this part you don't show, lol !. Thanks anyhow, it is a long process to replace that CPU
Awesome, the CPU replacement is in part 4 install, you can see it here ➜ czcams.com/video/GH2gUpYf6gc/video.html
look like a pain to replace my hp all in one was so simple
Yes, for the average user it is quite challenging to replace the CPU on the iMac. Eventually, I gave up on my old 2008 iMac and got a used 2009 Mac Pro 4.1 instead. In comparison it very easy to upgrade and much faster as well ➜ czcams.com/video/UoV4I-FlYdw/video.html
