    • 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?

  4. iMac Intel 27" EMC 2639 Teardown: Schritt 4, Bild 1 von 1
    • 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.

    • Die Fusion Drive Option kombiniert die große Speicherkapazität einer Festplatte mit der hohen Leistungsfähigkeit von Flash-Speichern, um kürzere Boot-Zeiten und schnelleren Zugriff auf Apps und Dokumente zu ermöglichen.

    i jst want to know if i can upgrade my graphics card to NVIDIA GeForce GTX 780M with 4 g.b memory,, is i ?!

    gforceemas - Antwort

    I would like to know, do they sell a ssd that can fit in that slot in step 4.

    Is it m.2 or mSata?

    Where can I purchase the SSD to utilize that slot?

    • Apples neue Auflage des iMac beinhaltet auch ein paar hinterlistige Änderungen im Gegensatz zum 21,5"-Modell und wir waren ziemlich entsetzt, als wir eine festgelötete CPU entdeckt haben.

    • 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).

    Scott Adams - Antwort

    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"?

    Daniel Gray - Antwort

    can i put this wifi card in my 2010 imac 27 i7 2.93 ghz?

    jess - Antwort

    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.

    • Schwergewichtige ICs:

    • 3.2GHz quad-core Intel Core i5 Prozessor

    • Intel platform controller hub

    • 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.

    • 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?

Christian Bille - Antwort

You'll need to remove the LCD and dig your way inside.

Miroslav Djuric -

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

Matthias Gasser - Antwort

I am also looking for the same info. Anybody has an ans?

imacsps -

Is the Thunderbolt port "Redwood Ridge", ie. DisplayPort 1.2 capable?

Robert Le - Antwort

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.

Scott Adams - Antwort

What we be required to install a second drive? I would like to keep the stock 1tb hdd and add a Samsung S30 SSD.

John - Antwort

Has discover how to add a second drive? thanks

janomixchile -

Do you think the cooling would support a 3 or 4TB hard drive and a 256 or 512GB SSD?

FredR - Antwort

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?

Ali Maadelat - Antwort

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.

Eric Haulenbeek -

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.

Michael Ybarra - Antwort

Is the GPU upgradeable? Can I swap a GeForce GTX 780m for the base 755m card?

California Aggie - Antwort

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?

Thomas Mosch - Antwort

This information is wrong. If you order the iMac with a fusion drive then the logic board has an SSD slot. If you don't order it with a fusion drive, it doesn't have that slot. Please correct your article.

Thor - Antwort

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.

Is it possible to install 2 ssd in raid 0 in a imac 27" late 2013. I have the one that comes with 1tb of hdd.

gera07 - Antwort

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

Terry Smythe - Antwort

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.

Pete Karnowski -

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.

Pete Karnowski - Antwort

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.

Pete Karnowski -

Rather than change parts and replace thermal paste to the heatsink and CPU, can I buy a new logic board?
