Einleitung
In der Ruhe nach dem iPhone 5s/c Sturm dachte Apple, dass es ein paar iMacs an uns vorbei schummeln könnte. Zeit für uns unsere Hebelwerkzeuge fertig zu machen und die nächste Generation des 27" iMac für eine schnelle Tour durch die Highlights weit aufzuhebeln.
Wir haben auch den neu aufgelegten kleineren Bruder iMac 21,5" – Schaue dir diesen Teardown auch an.

Was du brauchst
-
-
Von außen sieht der iMac Intel 27" EMC 2639 identisch zu den Vorgängermodellen aus, allerdings bekamen die internen Bauteile ein Upgrade.
-
3.2GHz quad-core Intel Core i5 Prozessor (Turbo Boost bis zu 3.6GHz) mit 6MB L3 Cache
-
NVIDIA GeForce GT 755M Grafikprozessor mit 1GB GDDR5 Speicher
-
802.11ac Wi-Fi
-
PCIe Flash SSD verfügbar
-
-
In diesem Schritt verwendetes Werkzeug:iMac Opening Wheel$7.99
-
Nach ein paar schnellen Schnitten mit unserem praktischen iMac Öffnungswerkzeug machen wir die Haube auf und haben ein sehr großes Deja-Vu.
-
-
-
Die AirPort/Bluetooth Karte, die mit dem 802.11ac Wi-Fi Standard kompatibel ist, ist immernoch an der Hauptplatine befestigt – Das heißt, die Reparatur ist nicht einfacher als vorher.
-
Nicht der erste Mac, der das Update auf den neuen ac Standard bekommt. Wir erwarten ähnliche Hardware wie in den neuen MacBook Airs aus dem Frühjahr diesen Jahres
-
Die neuen Chips:
-
Broadcom BCM4360KML1G 5G WiFi 3-Stream 802.11ac Gigabit Transceiver – wie vermutet ist das derselbe Chip, der das ac Wi-Fi in den 11" und 13" MacBook Air-Modellen ermöglicht.
-
Skyworks SE5516 Dual-Band 802.11a/b/g/n/ac WLAN Front-End Modul.
-
Broadcom BCM20702 Single-Chip Bluetooth 4.0 HCI Lösung mit Bluetooth Low Energy (BLE) Unterstützung
Replaceable Wifi card is excellent news. Question: is it possible to upgrade the WiFi card to 'ac' in previous Late 2012 iMac? If so, where can I buy that part?

Wie es jetzt Standard bei allen neuen iMacs ist, unterstützt der neue iMac 27" den PCIe-basierten Flash-Speicher. Das ist eine angenehme Überraschung, verglichen mit dem 21,5" Modell aus dem letzten Jahr, als wir von den unbesetzten Lötstellen auf unserer low-end Hauptplatine enttäuscht wurden.
-
Laut Apple erlaubt die Verwendung von PCIe Flash-Speicher bis zu 50% schnellere Geschwindigkeiten als die Vorgängerversion.
i jst want to know if i can upgrade my graphics card to NVIDIA GeForce GTX 780M with 4 g.b memory,, is i ?!

Gut, dass dem 27" großen Bruder dieses Schicksal erspart geblieben ist, sodass es Power-Usern weiterhin möglich sein wird den Prozessor auszutauschen, ohne ihn selbst ent- und verlöten zu müssen.
I've never heard of anyone buying a Mac expecting to upgrade the CPU (or ever having to replace one).
Not to mention that the reason the CPU is soldered in the 21.5" iMac is because it's the only formfactor Intel sells the CPU in with the Iris Pro graphics. You CANNOT get that chip with a socket. No way, no how.
Given this iMac does not need the Intel graphics, Apple went with the traditional socketed design.
Blame Intel for that one, not Apple.
(Though I agree - do people really upgrade their CPUs? Short of enthusiasts who upgrade every 6 months (who would never buy an iMac anyways...), by the time one finds the CPU too slow, it's time to upgrade the entire machine anyhow. Even on a PC you'd probably have to replace the motherboard, so soldered or not...).
Do we know which i7 they're using in the 27"?

I've done it before. If you're happy with the shell it's a great way to spend 10% of a computer's replacement cost and still enjoy a generational leap forward in performance. Made my G4 last 10 years that way through RAM, Graphics Card and Processor upgrades. This is the same thing. I bought a Haswell iMac 27 only because the screen is so much better than my iMac 24. Otherwise I would have figured out a way to stretch my $2400 investment from 2008. Did the same with a Macintosh Plus too. Well a 2 Mb upgrade and cutting the 256k resister. Still. I've always enjoyed messing with out of the box items.

Wie angegeben besitzt der iMac 27" einen neuen Grafikprozessor:
-
NVIDIA GeForce GT 755M GPU
-
Vier SK hynix H5GQ2H24AFR 256 MB GDDR5 SGRAM ICs bringen bis zu 1 GB Grafik RAM
Good day!
Is there any information about which exactly north bridge is installed on this model (ref to: Intel platform controller hub)?
Today I got my iMac 1419 from non-official service and noticeably work slower and image update very slow on the screen compared to late 2011 iMac sending next to this one.
Hola Tocayo, excelente explicación pero me podrìas orientar de como quitar el CPU, lo quiero actualizar a un core i7, gracias

iMac 27" EMC 2639 Reparierbarkeitsbewertung: 5 von 10 (10 ist am einfachsten zu reparieren)
-
Der RAM kann wegen der hinteren Zugangstür vom Verbraucher selbst gewechselt werden, ohne, dass das Gehäuse geöffnet werden muss.
-
Du kannst immernoch die Festplatte und die CPU ersetzen, auch wenn das mit ein wenig Kleber schneiden einhergeht.
-
Die Komponenten sind Modular und recht einfach zu entfernen.
-
Effektivitätsorientierte Menschen können jetzt aufgrund des Fusion Drive Konnektors auf der Hauptplatine eine zweite Festplatte in den iMac einbauen.
-
Das Glas und das LCD-Display sind miteinander verbunden und es gibt keine Magneten mehr, die das Glas an Ort und Stelle halten.
-
Du musst das doppelseitige Klebeband genau abschälen und neues Klebeband aufbringen um diesen iMac wieder zu verschließen und in seinen Originalzustand zurückzuführen.

You forget to mention *HOW* one should mount an extra SSD in the new port.
Do we need to remove the LCD panel or is there a slot you can access through the back, like with RAM?
You'll need to remove the LCD and dig your way inside.
On the BTO "SSD flash memory only model", is the SSD connected to the rear PCIe port leaving an empty SATA port? So someone could add an additional SATA drive?
Thx
I am also looking for the same info. Anybody has an ans?

Thanks for the tear-down...very nice as usual.
I'm glad we can still easily upgrade RAM on the 27" iMac. I would still like to be able to easily upgrade the HDD and/or SSD though - especially as SSDs get cheaper.
What we be required to install a second drive? I would like to keep the stock 1tb hdd and add a Samsung S30 SSD.
Has discover how to add a second drive? thanks
1) In order to "upgrade" the CPU, would you just "pop out" the current i5/i7 and plop a new one in? Are some not going to work? Would you need to do any software upgrades, etc.?
2) Same sort of question regarding the fusion drive slot. Would this only work with an apple fusion flash drive? could you just plop in a samsung, etc SSD? Any max for storage space?
There is no "popping out or plopping in" a replacement processor in this or any other iMac, save for some of the earliest G3 and G4 machines. If you're going to upgrade your processor then plan on replacing the mother board complete, and then only the particular board that fit into the same model machine. This is the only way an upgrade can be achieved without a lot of 'board level' experience, the sort that won't be addressed here. Popping and plopping is saved only for various PC variants but then we don't see much in the way of generic and mundane in the Mac world.
Ok just tore mine down thinking I could easily add a SSD drive to my 1TB sata setup. NOT. There is NO additional SATA port and the one that's on the MOBO is proprietary to Apple. So unless you have a converter that can adapt a STANDARD sata cable and power, then adding your own "Fusion Drive" setup is not going to happen. However, if you bought the SSD model then you can add the additional HDD but would still need to split power from their proprietary power cable. UGH.
Is the GPU upgradeable? Can I swap a GeForce GTX 780m for the base 755m card?
Does the fusion drive have a PCIe SSD and a standard sata HD or is it a special drive? Can it be splitted into two individual drives again?
Eric Haulenbeek.... I just hate it when people spout off things as if they were gospel when they have no friggin' idea what they're talking about. Case in point: your assertion that you can't upgrade the CPU in these Macs without board level tweaking. Utter nonsense! Pick a CPU that will fit the same socket and TDP and you're in business. To be safe, you should pick a CPU that Apple has already installed in the same model so that the firmware will support it. For example, you could replace the 3.2GHz Core i5 4570 with the 3.5GHz Core i7 4771. Whether this would be an economically wise course of action is another question.
I have a mid 2010 iMac 27, containing internally a 2TB conventional hard drive, and 240Gig SSD drive replacing the DVD drive. I’ve been offered an iMac 27 late 2013. Is there merit in swapping into it the 2TB and SSD drives from my 2010 model. Is there room and connectors to make this possible? Thoughts of others?
Regards,
Terry
It’s been a year since you wrote this… great time to use a Big Sur hack… the 2013 I just acquired doesn’t have a SATA port installed. But Amazon and eBay had one. Pull the logic board and hook it up. Then enjoy the extra data connection. Nvme to apple SSD adapter works with no sleep wake issues.
Did a CPU swap to a Xeon 1231 v3… thus far it will not POST or turn on. It leads me to believe/hope I didn’t connect the power supply well. I’m a little exhausted this was a rigorous job, tomorrow is another day. Insights welcome until then.
Got back in, bent some CPU pins…. daintily put them back. Go for boot. Recommendation remove the plastic ram cage and start reattaching the CPU from the side closest to the edge. I can’t confirm the Xeon didn’t work, I didn’t see a point in testing too variables for repair and another surgery afterwards.
Rather than change parts and replace thermal paste to the heatsink and CPU, can I buy a new logic board?
great job!! thankx alot but i want to know if i can upgrade my vcar to NVIDIA GeForce GTX 780M 4 gigs memory mine is 2 gigs any advice or how to do it plz?!
