Hi guys,
Does anyone has any news regarding upgrading iMacs 2011 with i7-3770?
Anyone successfull?
Thanks,

Tried it on 2 different imacs and it does not work.

I would like to upgrade if it works and it looks like we have two different experiences. Have the failed attempts to upgrade to the 3770 been with the 3770k or the plain 3770? I noticed in the intel site that the K version does not have the following:
Intel® Virtualization Technology for Directed I/O (VT-d) No
Intel® Trusted Execution Technology No
I noticed that this was the same for the 2700k that I am using right now that will not boot Mountain Lion. Could it be that the OS checks for these features?

great idea - shame there are so many conflicting accounts
Hello:
As I said in an earlier post in this thread, I've been in contact with those (one in this thread) that have had the most success, ex/ being able to boot & use the iMac 2011 with the Core i-3700, and they've reported continuing issues/errors with new program installations/OS X updates to the point the computer is unusable.
To put it simply; unless the necessary changes are incorporated into the Lion/ML installer file, Core i-3770 DOES NOT WORK in the 2011 iMac.
As stated above, this might change as updated OS X installer files are released for the 2012 iMac models.
Hey kennyap, aside from Hackerwayne was someone else able to get the imac to power on with a 3770?
Hackerwayne,
Can you help us find the bootrom you are using? You seem to have the only unit that will boot with a 3770.
Thanks,
Greg
Hi Freez3:
I have a Core-i7 2700k in my iMac.
Sorry to resurrect the thread. So am I OK to upgrade to 2700K as long as I have Lion? B1F and 1.72f1
Any updates on this thread with the 2011 iMac CPU upgrades now that Mavericks is out?

I just bought a 2011 iMac 27" for $600 and would really like to know if time / latest OS has solved the Ivy Bridge issue. Has anyone gotten an i7 3770S to work? Thanks!

It won't work. You'll need a BIOS/EFI whatever upgrade + updated kernel.
THANK YOU hackerwayne for putting this nasty rumor to bed.
So this may be an old thread but there's still life left in these older models, and by now we should know for sure exactly what's possible with the Sandy Bridge iMacs.
My gut instinct was exactly the same. Most Sandy Bridge-based PCs required updated BIOS/EFI to enable compatibility with Ivy Bridge CPUs.
To call it a "nasty rumour" is almost a denial of logic, there are more reasons why it shouldn't work than why it should work. A retail motherboard is one thing and there's every reason why a manufacturer would want as broad compatibility as possible, the biggest reason being to maximise sales. Manufacturers of integrated systems such as Apple and Dell, among others, have little to no incentive to broaden compatibility beyond the shipping spec for obvious reasons.
Anyone who's successfully modified an integrated system beyond its original specification deserves kudos but, unless I've missed something here, there's no evidence that hackerwayne actually managed what he claimed. I'm no "hater" and I'm not decrying anyone's hard work and effort but it's not unreasonable to expect people to substantiate their claims with evidence such as "About this Mac" screenshots, as has been requested several times.
It's also sad to see people bickering about peripheral issues such as RAM speeds, some members speaking as if with great authority when they simply haven't done their homework. For example Sandy Bridge supports DRAM up to 1333MT/s and Ivy Bridge up to 1600MT/s. It's not debatable, these are Intel's own specs, and the suggestion faster RAM with work at higher rates is nonsense in the context of an iMac. Sure, faster RAM is available but the speed limits are defined by the IMC not the RAM. Possibly the most crass comment I came across was referring to someone's "dumbass MBP", which may have been off-topic but comments like that are unhelpful and don't make the community a better place.
Why am I bothering to write this? We've got an estate of 120 Mid-2011 iMacs, and given our financial constraints it would be great if a CPU upgrade was possible, even if I suspected it was unlikely. SSD and RAM upgrades have taken them a long way from their original performance level but a CPU upgrade would be icing on the cake. Sadly it doesn't look like it's as simple as dropping in an Ivy CPU and expecting it to work seamlessly, which is what most Mac users would want, especially if it could prolong the life of a machine.
