Swap i7 CPU from Dell into 27" i5 iMac?

[Hellhammer]

This is true. Mainly due to the i7 9 series supports triple channel memory. Any board that is 1366 supports triple channel memory.

There is a lot more than just triple channeling. First off, LGA 1366 is physically different. It has 1366 pins while LGA 1156 has 1156 pins (or connectors). Secondly, LGA 1366 uses QPI while LGA 1156 uses DMI.

plus, that mainboards with 1156 socket do not have the ability to utilize USB3 and SATA-III fully (i.e. by loss of PCIe-lanes for the graphics card resulting in 8 instead of 16 lanes).

this could well be.

cant see any differences from ifixit teardown. so could be possible.

So, what I learned from this thread is that cracking open imac up to encountering that heatsink sticker does not intrinsically void the warranty (assuming no cracking takes place). Aside from the CPU sticker, were there other telltales at all?

I'm thinking about putting a SSD in, but was leery of the warranty issue. No longer though...

they sure will see at the apple store that yours was ordered with i5 so explain them that your i5 has upgraded itself to a i7
never mind its your iMac you paid for it , but there had been a couple now killing their iMac in the upgrade attempt ,they broke some of these very flimsy connectors inside and rendered the display or logicboard useless and that is not covered by the warranty then , and really expensive , you break something inside its your fault and not covered by the warranty, all upgrades are at own risk

and dependig what you do on your iMac you might not notice the difference anyway between the i5 and the i7


i just did want to make it clear upgrades on iMacs are entirely at own risk

CPU swap breaks a seal and is not honestly concealable.

I think for some of these posters, the risk is partly what makes DIY imac upgrading appealing. Like driving around w/o a license plate or
