New iMac 5k 2017 CPU is Upgradable?

Hey! This Summer i bought a new 2017 5K iMac with a i5 7600k.

So... The New Intel CPU 8700K is now available!

I just want know can I replace my i5 7600k to the new i7 8700k?

Is it possible to upgrade?

Thank You So Much

Here's a better vid on upgrading this system: The Best 2017 iMac Apple Doesn't Sell! Quinn only installed a i7-7700k

As far as the still newer Intel i7-8700k Apple hasn't used it yet in any of their systems and the micro code in the EFI won’t allow it. The best this system will support is a 4.2 GHz Core i7 (I7-7700K).

In any case keep in mind you'll be voiding your warranty here! And pulling off the display without using the correct tools and technique can kill it which would be an expensive Oops!

You will NOT be able to swap for the 8700 but you WILL be able to swap for the 7700 with no issues what so ever, literally on boot-up the system will immediately recognize the new CPU. The 8700 is a 6 core chip and they don't have any EFI to support that with the current OS. The iMac Pro doesn't even use the new Coffee Lake chip, so it may be doable in the future, but not as of yet. BTW, the latest iMac Pro uses Xeon chips for multi-threading and a kick-ass GPU, so that one will be upgradeable in the future. Hopefully, Apple will come up with some OS updates and the new 8th gen Intel chips will benefit.

Will the 8700 work now in such an iMac with the new High Sierra or Mojave updates?

Jiri, Will the 8700 work in a 2017 imac as of now with the latest High Sierra or better yet, Mojave updates?

von

Zack - Jiri believes the 8700 will not work and I second that! Again you can't run newer CPUs unless the system has the ability to support it. In this case both the TDP and the systems micro-code won't allow it.

von

Sorry I'm late to this question. The answer for the time being is that the 8700 cannot be used, mostly due to architecture (6 core vs 4 core) and the lack of instructions on the Mac boards. The 2018 Macs may cover the newer chip, but we won't really know that until September. Just so you know, unless you plan to run extremely intensive programs, the 7700 will do super fine. The TDP is fairly high for the 7700K swap, so I would personally recommend the T series for both better thermals and overall better per watt performance. I prefer the 7700T chip, also the 6700T chip is a winner IMHO.

von

Also, quick brainstorm to address newer versions of Mac OS - the software won't affect how the hardware operates, they cannot write in EFI code to 'make' the 8th gen chips 'fit.' This is a matter of hardware, although there may be BIOS updates to the mother boards, but keep in mind that Apple isn't encouraging changes to their hardware, so BIOS miracles are doubtful at best. I would agree that the 8th gen chips have better performance and thermals over the 7th gen, but again, I recommend T chips over the regular ones, and also recommend regular chips over the K unlocked version, mostly due to cooling concerns in the cramped and under-cooled Mac enclosure. The T chips are factory undervolted and they have amazing thermals.

I have successfully upgraded my iMac (Retina 5K, 27-inch, 2017) with an Intel i7-7700 and a 2TB Samsung 970 EVO NVME SSD. Please see post below for full details.

I don't know much about Macs, but I do know they much prefer people buy new things instead of upgrading. My guess is no, but it looks the people here might know better:

From what I read, it sounds pretty intense. Best of luck, I hope it works

Hi guys.

I have same question as well. My iMac is same model which is Mid 2017 i5 processor. But time already 2019 which does it upgradeable to i7 eight or nine generation?

Yes, I am wondering the same.

Some post said that chipset and volt usage are different, but it's been 3 years, I wonder if someone or apple has come up with new EFI?

von

Apple is the only source for the system firmware. While they do update it time-to-time they don't alter the microcode within the series to support newer chips.

So in your case the 2017 27" iMac can support only this chips iMac18,3. The highest performer in this series is a 4.2 GHz Core i7 (I7-7700K) CPU.

Nope! Can't be done the i7-8700 is not supported in the 2017 27" iMac.

The best you can go to is a 4.2 GHz Core i7 (I7-7700K).

oops! why I can’t log-in to ifixit by Google account anymore?!

I'm a bit confused! Now in macOS Mojave, is it possible to do that? or hardware doesn’t accept it!

Anyway. I’m going to bring my iMac 5K 2017 to London apple store and ask them to instal high-end CPU that it’s possible into it. :)

But, if I can replace i5 to i7 8700K, I will do that by myself. I just wanted to ask is it possible with 2017 iMac hardware condition or not. Because, I already knew that Apple will release an update for 8 generation Intel CPUs.

you' probably need a new MOBO to install the 8th gen intel chips

Nope just not possible! The best you can go to is a 4.2 GHz Core i7 (I7-7700K).

It could be done. Using an 8 gen I7 on H110 is possible now. And many articles claimed that 6 7 8 9 gen core CPU are compatible with each other’s socket. So, here is my guess: 1 If we need 8th 6core CPU installed, Some modification on the socket pins is necessary which is referred to some tutorials. 2 When Apple release new EFI to new coffee lake devices, can we transfer it back to this iMac?

That all, may this be helpful.

Apple is not rolling out a new EFI for this series which has newer micro code! There is other factors here than the EFI! First is the Power supply and the second is the thermal load the logic board is not designed to support anything but a 4.2 GHz Core i7 (I7-7700K) as the highest CPU.
