* iRevive guys -> Let me know if something needs to change here. Hope this helps.
Oh wow. This is really impressive! Thank you for taking time out of your day to time stamp every step. The fact that you went out your way to do this for us truly means a lot to me. Your contribution will aide viewers throughout their repair process.
@@iRevive maybe you could toss this into the video or description or something. there are TWO cables that fit the same on the logic board. the HDD fan and CPU fan cable are identical in fit. My HDD cable got caught and bent to a point that it looked like it *should* connect to the CPU fan cable. the CPU cable fell down and was hiding.
Your video walked me through disassembly and putting it all back together. I heat gunned the GPU to confirm that everything is working so that I can decide on what replacement GPU im going to toss in. ugly business all things considered. Taking apart an iMac isn't super difficult but it is not for the feint of heart either.
Outstanding video, award winning. Thank you for not using loud irritating inappropriate music. Your lighting, enunciation and explanations are outstanding. 5 stars!!
Thank you kindly for your feedback! I am pleased to hear that you enjoyed this video.
@@iRevive A really top notch presentation in all aspects f measurement, especially a technical one! One can rarely award a 10/10 but you have earned it as it is deserved. I am an ex UK IBM Agent and was used for major presentations in applications on IBM's Mid-range computers when they had 335,000 installed in Europe and until recently trained Uni students in presentation techniques for the global IET (UK based) Presentation Around The World annual competitions. I have saved your video for passing on the associates and students...
Spot on instructional video very clearly presented.
great job, Thanks
My iMac broke and I tough I bring it to apple and they would look at it and tell me what is wrong with it. They said to me its vintage and ready for the bin. I was like wtf you mean vintage? 10 years for a high end iMac! They must be joking but no they wouldn't even look at it. But thanks to you I fixed it myself. I know its 10 years old, but the i7 3.2Ghz and 2Gb video is still amazing in 2021, still manage to edit en do all stuff I need to do with it! I love the iMac 2011!.
Awesome! I am glad you are able to get more use out of your iMac.
Yeah Apple won't touch anything that's x amount of years old. They'd rather buy it from you and sell you a newer model.
Excellent teacher , calm , confident, measured and moreover , knows what he's talking about. Outstanding.
OMG thank you!! I just finished and are almost in tears. I fixed my 27" mid-2011. I couldn't have done it without your video! THANK YOU!!!!
That’s great news! I’m happy to hear you where able to bring your iMac back to life.
I realise that this is an old video but it's absolutely perfect! Thanks for sharing, it's very helpful and your calm, friendly manner is a breeze to watch.
This is the BEST video there is on tearing down & rebuilding a 27-inch iMac!!! This kid is AWESOME! BRAVO guys!!
Thank you. I am glad that you think so. There are some good videos out there on iMac repair on other channels. I am happy that this video has been a resource to you.
Thanks a lot for your great video - it encouraged and helped me to get my iMac 21.5" end-2009 back to life. In 2015 it "died", I took it to a repair shop, they confirmed a graphics card defect and wanted 400€ for a replacement without warranty. I didn't let them do the repair, kept the dead iMac and bought a cheap PC for the daily office work. Let's call it a "Corona-project", I took out the graphics card and baked it for 10 minutes at 200°C in the oven - I had nothing to loose - and it really worked!! On that occasion I also replaced the hard drive with a rather old 160GB SSD drive which I had used in my 2008 MacbookPro 15". This machine also died because of graphics card problems! However, thanks again for your video!
Update on 29 November 2021: I received the rebuilt GPU and it works great! While I had the iMac apart, I blew out all of the accumulated dust (which was a lot), replaced the BR2032 battery, and replaced the thermal paste on the main CPU with Arctic MX-4. The original thermal paste was now non-thermal gunk but cleaned up very well. Most of it fell away when I separated the heatsink from the CPU. I also installed the free version of Macs Fan Control so I could monitor the temperature and adjust the speed of the three fans. I have them set to run at 1500 RPM, but they will increase as required to meet the heat load. I hope to have a few more years of life out of this iMac before I replace it on my terms!!!
Excellent tutorial and a big thumbs up! The GPU in my Late 2009 iMac just gave up the ghost and I was going to send the iMac to the reclamation yard before I saw your video. I think it is easier to find unicorn tears than the replacement graphics card, but I found a service in Germany that will refurbish the GPU by replacing the processor and the thermal paste for about €140, which includes a one-year warranty. I send them the complete GPU, with heatsink attached, and three days later I receive my GPU back ready to install. I was tempted to try the oven bake, but for this amount, I don't want to bother and risk desoldering the components on the board. This makes it easy to kick that can down the road for another few years before I replace the iMac.
Thank you so much for such a well-done video. My GPU on my mid-2011iMac died. The previous GPU died two years ago, so I had the Apple store replace it for about $500. Of course, now this model is obsolete, so I'm pretty much on my own. Which is a good thing, considering design/manufacturing flaws of these video cards, I wouldn't pay Apple another $500 repair for such terrible reliability. Therefore, I baked my GPU in hopes of being one of the lucky ones to get another couple of years out of it. In the meantime, I ordered a new, non-Apple AMD Radeon HD 6970 2GB from China, that has supposedly been flashed to make it Apple compatible... Desperate times/desperate measures. I followed along with your video to do the the teardown, thermal pasting of the CPU and my freshly baked video card (by the way, the Apple store knuckleheads did not apply enough thermal paste to the VRAM; in fact, it looks like they applied the paste to the heat sink; when I cracked the GPU heat sink open, there was just a tiny amount of paste on a couple of the eight VRAM chips, while the heatsink had mostly unmated, undisturbed thin layer of paste above the VRAM chips). I appreciated you saying something about the battery. As my machine is eight years old, I figure since I'm in there, I might as well replace the battery. But I couldn't figure out how to get the battery out without the help of your video (the old battery was down to 2.75 volts. Before I put the LCD screen back on, I turned on the machine and looked at the four LEDs on the logic board. I had 1, 2, and through lighted, which was a sign that the GPU was communicating with the logic board. Then I turned off and unplugged the machine, installed the LCD with a couple of screws, plugged it back in and restarted. Voila!
This is awesome! I am pleased to hear that you were able to fix your iMac on your own. Bringing old Macs back to life makes me so happy. These units are still great machine and can continue to run if properly taken care like a car. Thanks for letting me know the success of your repair. I hope you continue to enjoy your iMac for many more years.
Hi, Could you share the link to purchase the GPU website?
when it dies. try to get a flashed Quadro K3000M they wont die. mine has been running for 2 years with heavy use
Hey quick question, I’m looking to bake my 2011 iMac graphics card as well. At what temperature did you set your oven and for how long was the card in there?
Excellent Tutorial, by far one of the best videos I've seen, so well executed and explained, thank you so much for sharing your talent and knowledge.
Excellent video, those old Macs can still work quite nicely
With enough TLC, these macs still operate just fine. Thanks for watching.
Man, I took the courage to change the thermal paste on CPU and GPU, thank's to your video. I have a 27" i7 from 2010. Huge thank's!!!!
Quality video man. I love how you include side subjects like not all GPU's being compatible. It shows some passion for your work. Kudo's brother
Thank you for your encouraging feedback.
Absolutely superb video. Fixed my 27inch mid 2011 iMac with a new 2gb graphic card. It's better than ever. Great job, thanks again.
Great job. I am happy to hear you were able to bring back some life to your iMac! Thanks for watching.
Brilliant tutorial,watching to fix my dead screen 2009 iMac. Apple wanted tons of money to repair and my local fixer guy probably too lazy to fix so told me to trash it . I refuse to give up on it . Learning so I can try and fix it myself. Thank you 🙏
Excellent. I hope this video will help bring back life to your iMac. Best of luck to you!
@@iRevive 🙏
This guy the best. He cover all the bases. Well done.
Thank you for your feedback. I am pleased that you found this video helpful!
my cousin and I successfully replaced the graphic card following your video, thank you for the great explanations!
That is awesome! I love hearing success stories. Good Job!
Thank you very much. Finally found someone that explains and shows how to repair this computer properly. What took me to repair my imac 27 i5 2010 was that it would start normally and at half the way it shuts down. My guess is that is the hard drive, since it has been shooing some problems. But I m not shure now if it is not the graphics card. I ll be unmountig my imac, change the thermal paste and dust it off. I hope it works, because this still is a great computer. Thanks again, and you did a great job. Best regards from Portugal.
Being that your model is a 2010 iMac, if the hard drive has not been replaced, it more than likely is going bad due to old age. What I would recommend is seeing if you can boot into safe mode by holding the left shift key while the computer boots.
Hi. Thanks for the reply. I've done that, Ré installed OS and it shut down again. I bought a new ssd compatible, new thermal paste and tomorrow I'll try to mount everything. Hopefully it'll work. Thanks again. You're the greatest. Best regards
I just did the bake on my graphics card and got it working, can't beleive it worked!!
Thanks so much for putting this content on here!!
Thanks very much for the tutorial, it's right on time 🙂 My second GPU failed Wednesday morning (mid-2011 machine that has served me very well).
Thank you. I hope this video was resourceful for your repair!
Very informative; I bought a imac 27" mid 2011; specifications: 180GB SSD with installed adapter, 32GB of ram, i7 quad core processor 2600 3.4GB, AMD Radeon 2GB Graphic Card, imacOS High Sierra, remote keyboard and mouse original, brand new power cord plus a backup spare, condition immaculate, even included the original box and packing material. I felt it was worth the $700. Canadian, "came fully serviced and cleaned". Inspection indicated no sign of usage, I suspect it had Miniman use from the original owner.
That's awesome. It sounds like you got a pretty nice set up. With just a little TLC, these iMacs can run for a long time.
Why do you only have 325 (326 now!) subscribers when you should have 325K?! Great work - and you're down with dosdude! Keep it up, man!
Collin is a great guy. If it wasn't for him, we wouldn't be able to bring 2011 15" MacBook Pros with failing GPUS back to life. Please continue to support dosdude1's work.
@@iRevive Amen, Brother. Been using his techniques and software for years. Saved me alot of headache with a MBP and an old Air just last month!
One of the best instructional videos I have seen on TH-cam. Just bought a 2011 imac..hope I don't have to revisit!!! Thanks
Great video. For DIY kind of people it can be absolutely helpful.
However, as I personally pulled out gpu on my imac, i have to say there is no need for removing logic board completely. It's ok for examining and cleaning cpu vent for example, or check of cpu/termal paste, or changing button battery br2032. But, gpu is actually easy for remove without mainboard removal.
Just don't forget to remove small cable which is plugged at bottom/inside side on mainboard BEFORE pulling gpu out from (still attached) mainboard/logicboard.
And also, it's important when removing display to be careful with removing 4 cables attatched on it, first one (at the upper left side of computer) is extremely easy to damage. Just don't pull display to much, do it slowly until you see (small) amount of space you have to work in.
So my algorithm for this is: 1. pull out small cable from logic board. *it's a bit tricky to put it back when reassembling, but if you are focused and not nervous, it will save much time vs taking out whole logic board. 2. unscrew three screws which hold heatsink shield fixed onto mainboard, loosen small screw close to screw that holds heatsink fixed onto computer frame/housing, and then unscrew this second screw. 3. pull gpu with heatsink and shield completely out. Be careful, pull the shield a bit up (so it won't scratch logic board), pull heatsink a bit up, and than pull it all out (into upper computer orientation). I put it back in reverse order. If you have big hands and fingers, you might need 90degree precise pliers to put small cable back.
Thank you for your feedback. I was unaware of the ability to remove the GPU with out the logic when I created this video. Fortunately, people have discussed in the comment section that you can save time by removing just the GPU by loosening up some screws. It’s a neat method. Like you said, removing the entire logic board does have its benefit to replace thermal paste while the device is open. But if you only need to replace the GPU, then there are methods to remove the GPU only without pulling the board. I’m not sure, however, if all A1312 models can have just the GPU removed.
What? Only 983 subscribers? Boy is this channel underrated.
Thank you! That means a great deal to me.
Great video. Was super useful. I just replaced a GPU in a 2011 27" iMac. Luckily I had two identical models so no parts cost!
Really this a fantastic training video. Thanks for the time and effort-it reboots!
Awesome. I love hearing success stories. Glad this video helped.
excellent video, the explanations on why your doing things in that order was valuable addition.
I agree the motherboard is marked up well, when I took my motherboard out I taped the wires back out of the way to ensure now get fouled or trapped behind the board.
Awesome! Thanks for sharing. This has just happened on my 2009 iMac! I'm not confident any local Mac specialist repair shop would do the job to your high standards.
There are plenty of competent Mac technicians around, you may need to ask around your local Facebook groups for someone reputable. I hope you are able to get your iMac fixed.
@@iRevive Maybe in the US but not where I live in the UK! I've just ordered a GPU Nvidia Card 1GB MXM for my 27" 2009 iMac model. Based on your video I've decided to to change the GPU and thermal compound myself. Do you list the equipment and materials needed to do this anywhere on your website?
@@bt2u4u Ahh. I see. I know a few technicians in the UK if you need a referral. As far as tools, I don’t currently have them listed in the description of the video, however I personally use an ifixit toolset for all my bits, and a suction cup for removing the glass. As far as thermal paste goes, I use MX-4 arctic for the GPU, and cooler master for the GPU RAM
Superb, clear and concise step-by-step instruction. Much appreciation for your know-how, time and efforts. Thank you ever so much.
Thank you for your feedback. I greatly appreciate it!
Excellent video. I will be replacing the GPU on my iMac based on your video. Thanks again.
Awesome video. I have one that i need to replace the VGA card so now after watching your video I will order a new card and do exactly the same repair. Wish me luck. 👍😎
I’m glad you liked it. Let me know how it turns out for you. Good luck!
I am about to follow this to replace the GPU in my 2011 iMac, this video is great!
Thank you for this video! I found a 2011 27" Mac on a curbside recently. It was making a lot of noise, so I thought I would need to replace thermal paste and clean it. With the help of your video I succeeded. Working smoothly and silently now!
Apple should give Estaban a prize for providing what they themselves don't provide.
This is one awesome walk through! Thank you so much for your time and effort making this. I really appreciate the little details, tips and tricks as those are very helpful. Diagonally opposite is the word I think you were looking for when talking of screwing down the heatsinks. Anyway, thanks again! I will be doing a CPU and GPU upgrade on my 2010 iMac soon. Moving up to core i7 870 CPU and a AMD WX7100 GPU. I already have a 500gb ssd installed as well as 16gb or ram. I will have to see if the new CPU supports 32gb of ram, if so I will max that out as well. All these upgrades should give me many more years of OS upgrades at a fraction of the price of a new machine.
This is awesome. I am happy to hear that this guide is able to assist you with your upgrades. I personally have not done CPU upgrades in iMacs for my clients so I am not sure if the CPU will support more RAM, but hopefully so. I wish you the best of luck with your repairs and hope you restore the iMac to better than new specifications.
Jeremy Carter: Have you done the CPU and GPU upgrade on your 2010iMac? I would like to do the same on my 27" iMac Mid 2010, 3.2 GHz i3 - upgrade to i7 and more memory. Do you think it is possible? Any answer are appreciated. And thank you iRevive for this awesome video with all the explanations
A well put together and thoughtful video. However there is no need to remove the power supply, or the fan or the super drive. I have worked on a lot of these iMacs and the logic board comes out without removing any of the aforementioned parts. In fact on the 2009, 2010 iMacs you can remove the GPU without removing the logic board at all. In the case of the 2011’s you do have to remove the logic board, as the screw heads on the GPU heat sink are behind the logic board, not so with the 2009, 2010.
I have heard of these methods before. I personally have not attempted to remove the GPU without removing the logic board on 2009 or 2010 models. Someone in the comments pointed me to a video with someone performing this method and I was rather impressed. You are also correct about not having to remove the power supply of super drive fan. I find it easier to remove and reassemble the logic board with these out of the way. But you can still perform the repair with the PSU and fan still installed. Thank you for sharing this information. This is how our industry gets better, by people sharing tricks and tips to helps others with repairs.
Great tips, thank you. I'm planning to replace the Thermal paste in mine. I knew how to get the memory out and the screen cover off, now I know how to do it all. Thanks for showing the way.
Thank you for your very good repair guide , I brought this model second hand in 2011 and has only developed a GC problem. Being retired for some years I
feel that a rebuild with a replacement GC can be a project during this winter. I have other macs which I can re watch your video.
Man, you are a star, my iMac mid-2010 is overheating, so I will use your video guide and try to fix it. Thank you a lot.
Thanks so much man for this video! When my graphics card on my mac died in 2016 I took it to Apple and they said that the card by itself would cost me £700. They told me it was best to give up and buy a new computer. The nerve! So I just abandoned my computer in the garage for the next 4+ years until a few days back when I was off work and decided to have a go at fixing it. Then your video came up and it looked so professional which is why I followed it. I ordered a used graphics card and MX 4 paste from Ebay and now my computer works great. It's fast because it has 32GB Ram and an SSD, so I hope it can cope for the next few years. Also, now I can mention "thermal compound" during a conversation with my friends and immediately sound very smart😂. Thanks man!
Amazing. I love stories like this. I am happy to hear that you were able to bring life back into your iMac. Thank you for your kind words!
@@iRevive now I have followed another tutorial to update the machine to Big Sur and all is well.
@@ernestmfakudze That is awesome. I am happy to hear that the Dosdude1 Patcher worked for you.
@@iRevive I can’t exactly remember which tutorial I followed regarding installing Big Sur. Anyway at the end I had to remove Big Sur and go back to supported High Sierra because the machine was just not stable, too many crashes and there were some sound issues in Windows inside Parallels. Now the worst has happened and I am back to square one: the card I put in was not new and today the machine started flickering while I was using it. I shut it down and when I tried to reboot it the pink vertical lines appeared and it wont boot into MacOS. The card is gone again, right? I want to buy a new one from China this time via eBay but before I do that I wonder if you have ever heard of the oven trick where you put the card into the oven at 200 degrees Celsius for 10 minutes and it bizarrely fixes it? Any thoughts on that?
I have a mid 2011 27 inch intel core i7 with the vertical lines on the boot up which convert into a grey screen. I think it’s my graphics card AMD Radeon 6970M 2048 MB ... based on your very detailed video. Which I appreciate. I think I might try and fix this myself based on this and another video I saw. 32 GB 1333 MHz DDR3.... OS X Lion 10.7.5.... Pray for me you guys. Without my iMac man I couldn’t even begin to explain how much that sucks during this pandemic.
Anyhow. Thanks. About to finish watching your video.
🙏🏾
The symptoms you are describing are indeed a failing Graphics card. Replacing the GPU will solve your issue. Afterwards, you may need to upgrade your operating system to something newer like macOS High Sierra. There is limited Application compatibility with OS X Lion these day. Best of luck!
I know that this video is for the 2009 iMac so the safety precaution below is pretty much OT but maybe food for thought
As per the iMac mid 2011 service manual
(Page 139) Re the LED backlight board for the 2011 iMac: If the computer is shut down by removing the power cord, allow the backlight board a good 2-3 minutes to discharge the capacitors before handling it. However, if you select “Shut Down” via the Apple menu, the computer will discharge the capacitors almost immediately.
(Page 16) Re Power Supply PCB: If the computer is shut down by removing the power cord, allow the power supply a good 2-3 minutes to discharge the capacitors before handling it. However, if you select “Shut Down” via the Apple menu, the computer will discharge the power supply capacitor almost immediately.
These Power supplies can be dangerous. It is best to allow the capacitors the discharge. Another way to force the caps to discharge is by removing the power cable from the iMac and holding the power button for a few seconds. It is best to avoid touching any components on the power supply as much as possible. I recommend holding the PSU by its edges away from any components or any obvious exposed traces.
Thanks for the tip on when to use Coolermaster vs Artic paste!
By far the clearest explanation. - excellent video. Thanks for this.
Was running Ventura with all updates via Open Core Legacy Patcher on exactly this late 2009 27" iMac (10,1), with the ATI Radion 4850 and the latest patches (thanks to Mr- Macintosh and the whole team of Mac-Heads), upgraded ist a few years ago to 12 GB RAM (non-Apple RAM), a 1 TB SanDISK SSD drive, Mac Fan Control installed and set the "HDD" ventilator to manual 2.000 rpm, as the SDD had no temperature sensor. Worked good, some minor hassle with the non-metal graphics still. But, really good for more years.
But yesterday I got the "Stripes go Death" and the system won't boot. Even re-installing the OS, trying backups from Time Machine, first-aid of the disk utlility manager, clearing SCM and so on... didn't work. I had to hardly learn that, obviously, my GPU / graphic card got fried. I remember I was trying 4K option for a TH-cam video lately, then switched to like "2K" which was running fluently again, just for a test. Normally it's set to the "auto" option. But as the creator of this video said: "This model cannot run 4K. It will try but eventually destroy the graphic card." And it did. Very sad. :( That masterpiece of a computer has been mine for 14 years (!) now and still had a super bright and clear 27" screen, not wasting too much energy and, with the help of Open Core Legacy Patcher, was able to run the most actual macOS and all it's security standards.
I am thinking of buying a new ATI 4850 graphic card to get the iMac back to life again. But I am not much of a technician and I am afraid, I will never get those parts together again. Nor do I want to spend like $400 for the repair of a 14 year old computer system. Maybe I will sleep over it and make a decision. Really don't wanna let my trusty friend iMac go.
Thanks for the detailed explanation alongside with tearing down the Imac
Thank you for this video, i'm going to fix my old 2011 imac 🙏🤞😅
Thanks! You saved my life already twice!
Thank you. I’m happy to hear this!
nice to see you work on the mac.😀
Great instructor and very helpful video. Thanks
I just watched another video that showed you can take out the GPU on the 2009 and 2010 without removing any other component.
I have seen this method before. Other people have mentioned this in other comments. I personally have not done this method, but from what I have seen, it is totally doable. The main benefit to disassembling the entire iMac is to give it a detailed cleaning and apply new thermal compound on to the CPU.
@@iRevive Yeah, you can def do it. I did it last night on mine and it wasn't hard to do. Then I took out the logic board and cpu together and worked on that afterward. If you use a blower, you can clean all the dust out without even removing any components. My vacuum is also a blower and a cloud of dust came out and it was all clean when I took the logic board out. I unfortunately have to bake the gpu or use a heat gun. The paste didn't solve my issue and purchasing a used or new card isn't worth it since it will happen again. Thanks for the vid!
Awesome explanatory tutorial !!!
I just want to say that since all the certified GPUs of 2011 earlier iMacs come to an end, wouldn't it be great if u guys did a tutorial on how to install non iMac certified GPUs?
There are a lot of 27" iMacs out there that have experienced GPU failure, so such a tutorial would be most "Revival" for our iMacs 🙂
Its a big shame to chuck into the dust bin such a computer... Esteban and Revive crew, plz help us! 🙂
There is a way to install a different graphics card that is not specifically made for these iMacs. I have been meaning to post a video on how to do this. But for the mean time, the macrumors link in the description has a list of compatible GPUs that can be used as replacements.
@@iRevive Thanks for replying guys, i appreciate it. Personally i really admire the work you do, its so professional.
Regarding the macrumors link, its got info but its chaotic. A video is way much easier to follow, especially for new unexperienced users. Im certain youll make a great one, i can't wait to see it :)))
@@iReviveany news regarding making a how to video about GPU replacement and installing a non Apple certified one?
By the way, seeing that the glass was broken it would have been safer to apply tape all over the glass before removing it because the glass on these things can really cut as it is not tempered glass.
Safety first. And a very fair point to make.
this video somehow hypnotised me
Got mine replaced! Thank you!
That is awesome! Another iMac saved from being e-waste.
This is great, thank you for sharing your knowledge. 2010 iMac with black screen, hope it’s the graphics card. Will try.
Sorry for the delayed response. I hope replace the GPU resolved your issue. If not, you may have a backlight issue with your LCD or inverter board.
Great video, how can one get hold of this graphics card for 27inch 2011 model imac? I have a 1gig graphics on my imac and its gone kaput. I baked it twice, first time it lasted for 6 months and second time, only 2 days.
After watching your video I have a hope to revive my iMac . Kindly could you put me in right direction.
Thank you for your feedback. I have a link to macrumors where there is a list of compatible GPUs in the video description. I hope this information points you in the right direction.
Thank you for making this video
You can remove the card while leaving the logic board in place
You are correct. I few people have mentioned this in the comments. I have not attempted this method. However, it is doable. I believe specifically on the 2009 and 2010 models.
Thank you sooo much!!! It really helped me to change it after the bake in my mid 2011 iMac
Awesome. I’m so happy that this helped you out.
This was a fantastic video. I have a mid-2011 3.1 GHz i5 with a seemingly failing AMD 6790 (one day the computer shut down and I was presented with the dreaded vertical green lines when trying to restart). I tried my attempt at the graphics card “bake”, which resulted in the computer chiming to a black screen. The LED test only shows the first two lighting up. I am trying my hand at a graphics card replacement but have a question about paste: Do you know anything about KP4 and KP5? The KP5 I used was much more “clay” like so I am wondering if I should just switch to the Arctic Silver MX-4 and use on all VRAM. I would hate to go back through the work of dissembling the logic board to apply paste that isn’t even working….
I would agree that your card has your issue here. I am inexperienced with KP4 and KP5, so I don't have any input on its quality. I would suggest using Artic MX-4 on your GPU die and VRAM just to be safe.
@@iRevive thank you so much for taking the time to reply, I really appreciate it. I am hoping the card comes in next week & we will see how it goes!
@@iRevive hello! Just wanted to give an update to you and anyone else in the future who may try to replace the video card. I ordered Arctic Silver MX-4 and used it on both the GPU and VRAM and am now typing this comment from my repaired computer. Thanks again for this video!
This is awesome! I am happy to hear your success story. Thanks for the update.
For a GPU replaces only then you do know you can replace the GPU without having to disassemble the whole machine. the GPU is mounted with 3 screws on the outside ,, where on the 2011 model is on the inside .. so if you remove the 3 screws remove the temp sensor then you can remove the GPU including the mounting bracket without further ado.. :)
I’m not sure what you mean. There are 2 screws in the back of the logic board that the GPU is held down with that can only be accessed by removing the logic board.
@@iRevive This guy shows it pretty good :)

@@MrRaebild interesting. I’ve never seen this method before. Thanks for sharing. :) I’ll have to try this out some time.
MUCHAS GRACIAS MEN, ME FUNCIONO MUCHO, SEGUI LOS PASOS AL PIE DE LA LETRA Y WOOOOWWWW PRENDIO MI IMAC, GRACIAS, SOY TU FAN JAJAJAJAJAJA EXITO!!!!
Lovely video, loved the fact that he did it in way that anyone can follow.
I do have a question though, i have a similar 27inch late 2009,i managed to upgrade it to high sierra and sudenly the screen went black. Now when i turn it on, no starting chime and still black screen. It seems to do something inside but i dont know what it is, any thoughts?
Great video! Lotsa of tips and gotchas! Only did the GPU bake, which not only cost nothing, but proved the problem is in the GPU. I'll have one sitting on the shelf for the next time it dies. Thanks again! Saved me the price of a new machine.
This is awesome. I love these comments, because it really shows that these computers still have life and if properly maintained will last a while. I’m glad this video helped you solve your issue!
Excellent video, thank you!
Just an FYI, the Apple Diagnostics that you can access using D or (alt-D over the internet) on boot is unable to detect a defective GPU - I found this to be true with whatever GPU failure my iMac 2011 AMD 6870M 2GB has.
This is good information to know for future reference. I was unaware. To be honest, I never use the built in Apple Diagnostics since it doesn't really give detailed reports and in some cases gives false negatives. I can only think of 1 time the the built in Apple Diagnostics helped me and that was to help me determine that a client installed the wrong RAM speed into the 2015 5k iMac. Outside of that one time, I find it faster to use other diagnostic methods. That is just my past experience with Apple diagnostics.
Thank you SO MUCH for sharing your knowledge. Sharing is caring!
I am glad you liked the video! If you are looking for more Mac repair knowledge I recommend checking our the Rossmann Group Discord. Lots of technicians sharing information there.
Amazing video thanks.
Is it necessary to use a different compound for the VRAM than the processor?
Eg. Can I use a high performance thermal paste for all of it, rather than buying a bulk amount of cooler master just for the VRAM?
You can use the same thermal paste on the VRAM as well.
Thankyou! So nice of you to reply to this old of a video.
@@JEPs. exactly, i totally agree!!!
Outstanding video😀
Thank you!
Good video. Revived my mac video card issue. cheers
This is great news. Thanks for sharing your success!
Like your work, so details and easy to learn.
Thank you! I am glad to hear that you like this video.
Thank you!
Much appreciate it!
A great video, very informative and useful, thakyou.
Hi, very nice presentation and so clear ! I do have a question and hopefully you can point ne in the right direction. In the last couple of months I encountered a shut down or a crash of my mid 2011 imac who served me flawless in all these years. But the crashes ended up in a grey screen with with lines horizontal lines like every centimeter. After reboot he worked fine again. Today I encountered tge,same thing but this time it didn't reboot anymore. No chime, screen stays black. When I push the power button it sounds as if the comp is waking from sleep stand...that typical noise. I do hear the fans working in the computer when trying to reboot, but nothing further happens. Tried all other short cuts to no avail. So, is it the CPU or the GPU that need replacement ? Any pointing in the right direction would be greatly appreciated...thank you and keep up the good work ! God bless !
Thank you for your kind words. Everything that you have describe sounds like a dead GPU. When a GPU gets too bad, it will prevent the entire computer from turning on. A GPU replacement will resolve your issue. I hope this helps out. Best of luck!
Ok, thanks for getting back and confirming it's gpu related. God bless !
thank you, first class quality job .
fantastic awsome explanation thats the right way to do so my compliments , only 1 question , how many times a year do you have to put on paste on the CPU + GPU ? can you explain that in a video to please to make it completely clear for all those people who have apple mac desktop computer !
Thanks for a great video!
Can you just pull the wires up to disconnect the connectors? Makes me nervous. Thanks
Hello. Great and informative video. I have one old iMac mid 2011 and I struggle with it right now. The LCD cable is broken and a new one is on its way but I suspect that Its not the only problem. The iMac boots up fine but after awhile sometimes enter a few minutes and sometimes enter several hours the screen turns black and but you hear the computer runs still. I will give it some more time and love but otherwise I will look for a newer one. Regards from Sweden 🇸🇪
Good afternoon. Sorry for the delayed response. Is there any update on this one? If the screen goes black after a while but the computer is staying on, it could be possible that the Backlight inverter board is going bad or the LCD LEDs are going bad.
@@iRevive Hello. Thanks for your respond. I’m a total amateur and after several other fixes I now had ordered a new backlight inverter board and hoping that is the problem. Best regards from Sweden 🇸🇪
Thank you for the video! Very hello full! Please do a video for ssd upgrade in this and if there is possible to get higher gpu it cpu?
The best explanatory video I have seen. 👀..Now going to do the job 😎 Mant thanks for the info. ✅🤙
Keep us updated. I hope it all goes well.
You're Amazing and very kind, thank you for the lesson!
Very informative tutorial. Thanks for the video.
Thank you. I hope this video helps you out.
Your video was great. I am replacing my iMac 2011 graphics card and should receive the new card next week. Can you tell me what diagnostics you used to check out the iMac after assemble?
nice work bro~Thanks！
I’m glad this video helped!
@@iRevive I fixed my imac according to your video ,thanks again
Awesome video dude. Well done
Hi.I have a iMac 27” I have had the computer for nine years the cover screen is held on by magnets.The problem I have is when powered up the start up sound comes on but the screen stays black (nothing at all) if you give can give some advice...I would appreciate it. Thank you.. Great Tutorial.
Thanks Gordon. A black screen can be caused by a bad GPU, bad backlight inverter board, or bad LCD. The first step to try is to take a flash light to the screen and see if there is any image on the LCD. If you have an image, then your backlight has failed, if there is no image, then move on to connecting the iMac to an external display using a Mini Display Port to HDMI cable. If you get an image, then your LCD is the culprit, if you don't get an image, then you might be looking an a failed GPU. The last step is the open up the iMac up and check the 4 LED Diagnostic lights. on the mother board. If you are only getting 2 LEDs lit up, the your GPU has failed and needs to be replaced. I hope this little guide helps you restore your iMac!
Great and detailed, explanation! Thanks to that I took the chance on upgrading my iMac 2011 's GPU to 2GB, I added Thermal Grizzly Paste to that, But apparently I added less than needed, 'cause two weeks later screen started to flash after using InDesign 2015 for some hours daily. If I buy the MX- 4 paste, how much in grams would you suggest to put on the card? Should I buy more thermal grizzly? or is it convenient to change it all?
Hi there. Sorry for the delayed response. Grizzly paste is adequate to MX-4. I usually use a dot about the size of a pea on the GPU die. It is also possible that the replacement GPU is defective. I hope you were able to resolve this issue.
sir i have an a1312, when turn on, can see apple logo and loading bar, the loading is slow especially above 60 or 70%, it stuck at apple logo even the bar reach 100%, no lining on screen, everthing is perfect. could it be graphic card issues?
Sorry for the delayed response. If you are still having this issue, it can be caused by either a failing hard drive or a bad graphics card. If you have not serviced the HDD before, it is possible that you issue may just be a bad HDD. Hard drives typically have a life expectancy of 5 years. When they fail, they can have all of your symptoms. How we test this out at our shop is by booting into an external test drive with a bootable copy of macOS. If the test drive boots up all the way, the GPU is fine and the issue is more than likely the HDD. If you do not have a test drive, you can create a macOS installer by using Dosdude1 High Sierra Patcher found here. dosdude1.com/highsierra/ I hope this information helps guide you. Keep me updated!
Are you still answering questions? I'm just wanting to know if it's ok to use the Arctic MX4 on the GPU memory as well.
Yes. You can use that thermal paste on the GPU RAM as well.
Wow, what a great expertise! That styrofoam solution killed me :)
I have question considering parts. My local repairsmen have recommended avoiding eBay cards as there's a high risk of running into an old one wich has just been rufurbished and will run for weeek or two and then die for good. So they offer to swap the chip itself instead. I must admit it's hard to give up on a "new" card as it offers 2gb, while changing the chip would mean I'll be stuck with stock 1gb.
Any thoughts on that? Would you recommend some reputable seller which you've metioned earlier in the comments?
Thanks!
brilliant
Thorough
Well communicated
You are doing a great service
Thank you Moses for your feedback. I appreciate it!
A very professional tutorial
Thank you!
@@iRevive no problem this vid helped me alot
Great video, thanks very much for the info!
Thank you! I am glad you found it useful.
Great Video!! Where can the same graphics card you have used for this video? Thanks
Sorry for the delayed response. Been out of commission after having my wisdom teeth removed. Graphics cards are becoming increasingly difficult to obtain due to supply and demand. However, I left a link in the description to a list of compatible graphics cards on macrumors. I recommend checking out the list. I hope this information helps out.
Thanks for this useful video! would you be able to drop a link where I can buy the replacement GPU unit?
Hi Josh. I don't have any direct links to replacement GPUs. However, in the description, I have a link to a list of compatible GPUs listed on macrumors website.
Hi ! Very nice and still up to date ! Just done with a S7100x firepro . Do you know is there is a way ton get the apple logo startup back ?
Thank you! I am not sure how to get the Apple logo with the firepro GPU. But I do know that with a NVIDIA Quadro, you can flash the VBIOS to bring back the Apple logo. There is a MacRummors link in the description where there is a discussion on installing 3rd party GPUs including the firepro. There might be information there on how to bring back the Apple logo after installation.
