Wich version is it? Can't see the ssd port. Any trouble booting the new CPU?

Lisandro - This version of the logic board does not have the Blade SSD socket. So it can only support the one SATA drive.

As to the CPU as long as Ted uses what this series offered for a CPU option he's good!

@yddet98 - Thanks for showing us the 21.4 4K i3 boards are socketed, good to know!

Yes, But… You'll need very special tools if the CPU is mounted via BGA. Otherwise, if it's mounted via socket, you can upgrade it to a later version as long as the CPU structure and pin arrangement is the same as the original.

However, be warned that opening the Mac will void your warranty. You can't get Apple components for replacement easily, because Apple keeps those under wraps and exclusively avaliable for licensed Apple technicians only, so definitely don't damage anything!

Good luck.

as long as the new CPU structure and pin arrangement remains the same, there is no problem upgrading from a 8700k i7 to an 9th gen i9 ?

Sorry for the REALLY late reply, I'm very busy trying to raise money to start my business in repairing video game consoles.

Yep, basically. And if it doesn't work, you've probably got an incompatible CPU. However, I am quite certain the structure would be different if it wasn't compatible. Therefore, you should be fine as long as, like you said, the structure is the same.

You are wrong Sterling, for newer CPUs you will still need BIOS update for them to work.

you cant use Gen9 on Gen8 without bios update . even they are the same structure and work on the same board. and there is no way Apple will give you that bios.

@uhrwerkkwx - The 4K models have a socket the lower end systems tend to be soldered CPU's in the 21.5" iMac's.

Intel's i9's can't be used in this series as the TDP is so high for the system and the systems firmware won't support it. Unlike Windows PC's you can't alter the systems firmware. Each generation of CPU requires different micro-code which is what holds you back here.

@danj Ah, I suspected. Apple machines tend to differ model to model but for the most part (if I'm not mistaken) they can be CPU upgraded as long as Apple's product specifications state it. But as you said, they do change the firmware compatibility a lot, and so it can be hard to CPU upgrade if you don't know what you are working with. Thanks for the correction, I can sometimes make small mistakes like that.

Yes it can. It uses a regular intel 8th-9th gen wicket with a Q370 chipset. Idk how the cooling will handle let’s say a 9900K, but it is possible

Very true! The chipset supports the better chip. But that's the easy part ;-}

The micro-code within the systems BIOS needs to support the chip. This is where we have an issue with the iMacs unlike many Windows systems. You also have power and cooling issues going any higher than what the system is able to support.

I have an iMac19,2 and I want to upgrade to a 9900, but I'm afraid that it won't boot because of that. my current 8100 is very slow and an 8700 is very overpriced currently.

da

The best CPU your system will support is this I7-8700 which you could upgrade your system to! Have you priced out the CPU yet?
